I'm trying to give resource folder for Freemarker template below is my bean config
Configuration freeMarkerConfig() throws IOException {
Configuration cfg = new Configuration(Configuration.VERSION_2_3_29);
cfg.setDirectoryForTemplateLoading(new ClassPathResource("ftl").getFile());
return cfg;
}
and I have ftl folder in the resources folder
-- java
-- resources
-- ftl
-- template.ftl
while deploying it works fine in my local machine but fails in my docker container with exception
java.io.FileNotFoundException: class path resource [ftl] cannot be resolved to absolute file
path because it does not reside in the file system: jar:file:!/BOOT-INF/classes!/ftl
I need to keep ftl in the resources folder and give the directory path to configuration. I don't know how to debug further.
Property spring.freemarker.template-loader-path is available.
spring.freemarker.template-loader-path=classpath:/ftl/
Or, use setTemplateLoaderPath("classpath:/ftl/") instead of setDirectoryForTemplateLoading().
I found the issue after repeated searching. Issue is because of this
Classpath resource not found when running as jar
my springMVC project not able to locate the config directory
My application directory structure is--
myapplication
+src/javaApplication
+webcontent
+web-inf
+jsp
+lib
+config
while accessing this configuration I am getting an error
SEVERE: Servlet.service() for servlet [springsocial] in context with path [/socialmedia] threw exception [Handler processing failed; nested exception is java.lang.ExceptionInInitializerError] with root cause
java.util.NoSuchElementException: 'babelnet.minEdgeWeight' doesn't map to an existing object
I am trying to use babelnet in springMVC application. where should i put the configuration details in spring please suggest.
thanks in advance.
In general, your file hierarchy should probably be something like this:
/src
/main
/java
/resources
/webapp
/WEB-INF
/test
/java
Configuration files that need be be on the classpath should go into the /src/main/resources directory. Config files that you reference directly can go pretty much anywhere, but probably belong either in the resources folder or the WEB-INF folder, depending on the context of their use. Spring MVC configuration files should go into /src/main/webapp/WEB-INF.
Resource resource = new ClassPathResource("classpath:src/main/resources/template/datafields.properties");
Properties props = PropertiesLoaderUtils.loadProperties(resource);
Your problem is that your file is actually not in the application classpath. Looking at your folder paths I am assuming that you have a maven project structure and your properties file is present within resources directory. When your project is compiled, everything inside the resources directory is at the root of the classpath along with your compiled java classes. So you should instead use
Resource resource = new ClassPathResource("template/datafields.properties");
Classpath resource loads resources from the application classpath, so you need to be aware what all directories/jar files are in your classpath and their directory structure to successfully load resources.
I've got some XML files under my WEB-INF directory:
lyricsBaseApp-servlet.xml
hibernate.xml
dataSource.xml
beans.xml
the servlet xml imports other xml files:
<import resource="dataSource.xml"/>
<import resource="hibernate.xml"/>
<import resource="beans.xml"/>
I would like my junit4 JukeboxTest class to include entire spring configuration. Using default filename I have created a JukeboxTest-content.xml file. And finally, I do not know what to put there...
I've tried:
<import resource="/WEB-INF/dataSource.xml"/>
<import resource="/WEB-INF/hibernate.xml"/>
<import resource="/WEB-INF/beans.xml"/>
or
<import resource="classpath:./WEB-INF/dataSource.xml"/>
<import resource="classpath:./WEB-INF/hibernate.xml"/>
<import resource="classpath:./WEB-INF/beans.xml"/>
and some other ideas but all failed. Could someone point me how to access those files and what way spring interprets those filepaths?
Option 1 (should be preferred as it's the best practice):
Refactor your config files under WEB-INF and move the common parts (that you want to access also from integration tests) to src/main/resources/. Then write test specific configuration files in src/test/resources/ (if you only need to import several different config files from src/main to assemble your test context, then skip this, and use #ContextConfiguration preferably).
Option 2 (hack):
Use references like:
#ContextConfiguration("file:src/main/webapp/WEB-INF/dataSource.xml")
Option 3 (hack):
If you have a Maven project, you can configure the maven-surefire-plugin (used in the test phase) to declare src/main/webapp as an additional classpath element during test execution.
The latter two options are considered as hack, because files under src/main/webapp are simply not supposed to be on the classpath.
Now the detailed explanation:
The reason why you can't refer to these files as classpath:/WEB-INF/*.xml is that they are indeed not on the classpath. It's important to understand how your webapp is packaged, and what exactly ends up on the classpath. Assuming a default Maven project structure:
Java classes from src/main/java go to /WEB-INF/classes after compilation.
Resources from src/main/resources go to /WEB-INF/classes as well.
Project dependencies go to /WEB-INF/lib.
Everything you have in src/main/webapp goes to / (root of the package). This means that all files from src/main/webapp/WEB-INF go to /WEB-INF, of course.
The most important thing to know is that the classpath will only contain /WEB-INF/classes and one entry for each jar in /WEB-INF/lib. Consequently, resources outside these two locations are completely invisible for the classloader. This is also true for the xml config files directly under /WEB-INF, which is why the reference classpath:/WEB-INF/dataSource.xml will never work.
You may ask yourself, how the hell are then these xml config files loaded by Spring if they are not reachable from the classpath? The answer is simple: When you start your webapp (as opposed to executing just unit/integration tests), it is running in a Servlet Container which provides access to the ServletContext (an actual class from the Servlet API), so it uses ServletContext.getResourceAsStream() to load these files. The key for understanding is the following quote from the javadoc of this method:
This method is different from java.lang.Class.getResourceAsStream, which uses a class loader. This method allows servlet containers to make a resource available to a servlet from any location, without using a class loader.
Sorry this become way too long, but that's the whole story...
try this
#ContextConfiguration(locations = {"classpath:**/dataSource.xml",
"classpath:**/hibernate.xml",
"classpath:**/WEB-INF/beans.xml"})
I am trying to make my first bean in Spring but got a problem with loading a context.
I have a configuration XML file of the bean in src/main/resources.
I receive the following IOException:
Exception in thread "main" org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [src/main/resources/beans.xml]; nested exception is
java.io.FileNotFoundException: class path resource [src/main/resources/beans.xml] cannot
be opened because it does not exist
but I don't get it, since I do the following code test:
File f = new File("src/main/resources/beans.xml");
System.out.println("Exist test: " + f.exists());
which gives me true! resources is in the classpath. What's wrong?
Thanks, but that was not the solution. I found it out why it wasn't working for me.
Since I'd done a declaration:
ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");
I thought I would refer to root directory of the project when beans.xml file was there.
Then I put the configuration file to src/main/resources and changed initialization to:
ApplicationContext context = new ClassPathXmlApplicationContext("src/main/resources/beans.xml");
it still was an IO Exception.
Then the file was left in src/main/resources/ but I changed declaration to:
ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");
and it solved the problem - maybe it will be helpful for someone.
Edit:
Since I get many people thumbs up for the solution and had had first experience with Spring as student few years ago, I feel desire to explain shortly why it works.
When the project is being compiled and packaged, all the files and subdirs from 'src/main/java' in the project goes to the root directory of the packaged jar (the artifact we want to create). The same rule applies to 'src/main/resources'.
This is a convention respected by many tools like maven or sbt in process of building project (note: as a default configuration!). When code (from the post) was in running mode, it couldn't find nothing like "src/main/resources/beans.xml" due to the fact, that beans.xml was in the root of jar (copied to /beans.xml in created jar/ear/war).
When using ClassPathXmlApplicationContext, the proper location declaration for beans xml definitions, in this case, was "/beans.xml", since this is path where it belongs in jar and later on in classpath.
It can be verified by unpacking a jar with an archiver (i.e. rar) and see its content with the directories structure.
I would recommend reading articles about classpath as supplementary.
Try this:
new ClassPathXmlApplicationContext("file:src/main/resources/beans.xml");
file: preffix point to file system resources, not classpath.
file path can be relative or system (/home/user/Work/src...)
I also had a similar problem but because of a bit different cause so sharing here in case it can help anybody.
My file location
How I was using
ClassPathXmlApplicationContext("beans.xml");
There are two solutions
Take the beans.xml out of package and put in default package.
Specify package name while using it viz.
ClassPathXmlApplicationContext("com/mypackage/beans.xml");
src/main/resources is a source directory, you should not be referencing it directly. When you build/package the project the contents will be copied into the correct place for your classpath. You should then load it like this
new ClassPathXmlApplicationContext("beans.xml")
Or like this
new GenericXmlApplicationContext("classpath:beans.xml");
This is because applicationContect.xml or any_filename.XML is not placed under proper path.
Trouble shooting Steps
1: Add the XML file under the resource folder.
2: If you don't have a resource folder. Create one by navigating new by Right click on the project new > Source Folder, name it as resource and place your XML file under it.
use it
ApplicationContext context = new FileSystemXmlApplicationContext("Beans.xml");
You have looked at src directory. The xml file indeed exist there. But look at class or bin/build directory where all your output classes are set. I suspect you will need only resources/beans.xml path to use.
I suspect you're building a .war/.jar and consequently it's no longer a file, but a resource within that package. Try ClassLoader.getResourceAsStream(String path) instead.
Note that the first applicationContext is loaded as part of web.xml; which is mentioned with the below.
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>META-INF/spring/applicationContext.xml</param-value>
</context-param>
<servlet>
<servlet-name>myOwn-controller</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>META-INF/spring/applicationContext.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
Where as below code will also tries to create one more applicationContext.
private static final ApplicationContext context =
new ClassPathXmlApplicationContext("beans.xml");
See the difference between beans.xml and applicationContext.xml
And if appliationContext.xml under <META-INF/spring/> has declared with <import resource="beans.xml"/> then this appliationContext.xml is loading the beans.xml under the same location META-INF/spring of appliationContext.xml.
Where as; in the code; if it is declared like below
ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");
This is looking the beans.xml at WEB-INF/classes OR in eclipse src/main/resources.
[If you have added beans.xml at src/main/resources then it might be placed at WEB-INF/classes while creating the WAR.]
So totally TWO files are looked up.
I have resolved this issue by adding classpath lookup while importing at applicationContext.xml like below
<import resource="classpath*:beans.xml" />
and removed the the line ClassPathXmlApplicationContext("beans.xml") in java code, so that there will be only one ApplicationContext loaded.
In Spring all source files are inside src/main/java. Similarly, the resources are generally kept inside src/main/resources. So keep your spring configuration file inside resources folder.
Make sure you have the ClassPath entry for your files inside src/main/resources as well.
In .classpath check for the following 2 lines. If they are missing add them.
<classpathentry path="src/main/java" kind="src"/>
<classpathentry path="src/main/resources" kind="src" />
So, if you have everything in place the below code should work.
ApplicationContext ctx = new ClassPathXmlApplicationContext("Spring-Module.xml");
Gradle : v4.10.3
IDE : IntelliJ
I was facing this issue when using gradle to run my build and test. Copying the applicationContext.xml all over the place did not help. Even specifying the complete path as below did not help !
context = new ClassPathXmlApplicationContext("C:\\...\\applicationContext.xml");
The solution (for gradle at least) lies in the way gradle processes resources. For my gradle project I had laid out the workspace as defined at https://docs.gradle.org/current/userguide/java_plugin.html#sec:java_project_layout
When running a test using default gradle set of tasks includes a "processTestResources" step, which looks for test resources at C:\.....\src\test\resources (Gradle helpfully provides the complete path).
Your .properties file and applicationContext.xml need to be in this directory. If the resources directory is not present (as it was in my case), you need to create it copy the file(s) there. After this, simply specifying the file name worked just fine.
context = new ClassPathXmlApplicationContext("applicationContext.xml");
Beans.xml or file.XML is not placed under proper path. You should add the XML file under the resource folder, if you have a Maven project.
src -> main -> java -> resources
I did the opposite of most. I am using Force IDE Luna Java EE and I placed my Beans.xml file within the package; however, I preceded the Beans.xml string - for the ClassPathXMLApplicationContext argument - with the relative path. So in my main application - the one which accesses the Beans.xml file - I have:
ApplicationContext context =
new ClassPathXmlApplicationContext("com/tutorialspoin/Beans.xml");
I also noticed that as soon as I moved the Beans.xml file into the package from the src folder, there was a Bean image at the lower left side of the XML file icon which was not there when this xml file was outside the package. That is a good indicator in letting me know that now the beans xml file is accessible by ClassPathXMLAppllicationsContext.
This is what worked for me:
new ClassPathXmlApplicationContext("classpath:beans.xml");
If this problem is still flummoxing you and you are developing using Eclipse, have a look at this Eclipse bug: Resources files from "src/main/resources" are not correctly included in classpath
Solution seems to be look at properties of project, Java build path, source folders. Delete the /src/main/resources dir and add it again. This causes Eclipse to be reminded it needs to copy these files to the classpath.
This bug affected me when using the "Neon" release of Eclipse. (And was very frustrating until I realized the simple fix just described)
I was experiencing this issue and it was driving me nuts; I ultimately found the following lying in my POM.xml, which was the cause of the problem:
<resources>
<resource>
<directory>src/main/resources</directory>
<filtering>true</filtering>
<includes>
<include>**/*.properties</include>
</includes>
</resource>
</resources>
I was not sure to write it but maybe someone save a few hours:
mvn clean
may do the job if your whole configuration is already perfect!
I have stuck in this issue for a while and I have came to the following solution
Create an ApplicationContextAware class (which is a class that implements the ApplicationContextAware)
In ApplicationContextAware we have to implement the one method only
public void setApplicationContext(ApplicationContext context) throws BeansException
Tell the spring context about this new bean (I call it SpringContext)
bean id="springContext" class="packe.of.SpringContext" />
Here is the code snippet
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
public class SpringContext implements ApplicationContextAware {
private static ApplicationContext context;
#Override
public void setApplicationContext(ApplicationContext context) throws BeansException {
this.context = context;
}
public static ApplicationContext getApplicationContext() {
return context;
}
}
Then you can call any method of application context outside the spring context for example
SomeServiceClassOrComponent utilityService SpringContext.getApplicationContext().getBean(SomeServiceClassOrComponent .class);
I hope this will solve the problem for many users
I am on IntelliJ and faced the same issue. Below is how i resolved it:
1. Added the resource import as following in Spring application class along with other imports: #ImportResource("applicationContext.xml")
2. Saw IDE showing : Cannot resolve file 'applicationContext.xml' and also suggesting paths where its expecting the file (It was not the resources where the file applicationContext.xml was originally kept)
3. Copied the file at the expected location and the Exception got resolved.
Screen shot below for easy ref:
But if you would like to keep it at resources then follow this great answer link below and add the resources path so that it gets searched. With this setting exception resolves without #ImportResource described in above steps:

Sharing my case and how I debugged it, maybe helps someone:
this will only be relevant if you have first checked you actually have the resources folder in correct place and correctly named
create some temporary folder somewhere, preferably out of any git projects (e.g. mkdir playground) and move there (cd playground)
copy the java archive there (e.g. cp /path/to/java.war .) that is missing that beans.xml
unpack it (e.g. unzip java.war on ubuntu)
find if there's any .xml files in there (for example in WEB-INF/classes) (the unpacking process should show a list of files being unpacked, most of them will probably be other dependencies as archives, these are not relevant)
if you don't see a beans.xml, just read the other .xml files (e.g. cat root-config.xml), you might find something like root-config.xml there or similar, in there you might either have some other <import resource="somethingelse.xml"> records or nothing.
if this is the case, this means you do have that file (root-config.xml here) present in the project or if not, continue going up parent projects to where the archive is getting packaged from. Find that file, add <import resource="beans.xml"> and run mvn package.
Now verifying the fix by doing the steps in 1.-5. should result in that file (root-config.xml here) in the newly packaged archive having the beans.xml defined and once you deploy it, it should work.
Make sure that beans.xml is located in the resources folder.
