Greetings,
I am working on a spring based web application. Situation is :
there are two .xml file one application-context.xml , other is default-context.xml
application-context.xml will be load to web context when tomcat started ,which is configured in web.xml
application-context.xml ServletContextPropertyPlaceholderConfigurer loaded some properties.and import default-context.xml
because default-context.xml is in another project, and I want it have its own .properties(default-context.properties) file and set up a ServletContextPropertyPlaceholderConfigurer for it to load the properties.
the current result is that : the properties in default-context.properties is not loaded, and the ServletContextPropertyPlaceholderConfigurer in default-context.xml is not inited. It reports
can't resolve placeholder for xxxxxx"
I tried some combinations,
1.to load default-context.properties in application-context.xml 's ServletContextPropertyPlaceholderConfigurer ,its worked.
2.to load default-context.properties in application-context.xml 's PropertyPlaceholderConfigurer ,NOT work. I guess its because the PropertyPlaceholderConfigurer can't be load to servlet context?
3.loading default-context.properties in default-context.xml in both ways (ServletContextPropertyPlaceholderConfigurer or PropertyPlaceholderConfigurer)
NOT work.
I can't figure out why there's only one ServletContextPropertyPlaceholderConfigurer can be configured in servlet context?
configuration is like :
in application-context.xml
<class="org.springframework.web.context.support.ServletContextPropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:etc/system.properties
</value>
...
in default-context.xml :
<bean id="tempName123"
class="org.springframework.web.context.support.ServletContextPropertyPlaceholderConfigurer" >
<property name="locations">
<list>
<value>classpath:etc/default-datasource.properties</value>
</list>
</property>
</bean>
You can use different placeholder prefix and suffix for second bean. With following declaration you can use placeholder as #[some.property.name].
<bean class="org.springframework.web.context.support.ServletContextPropertyPlaceholderConfigurer"
p:location="classpath:etc/default-datasource.properties"
p:placeholderPrefix="#["
p:placeholderSuffix="]">
</bean>

I am loading property file in spring-context.xml and i am giving
external property file location in
${spring.profiles.active}.properties which is in classpath and using the location as a placholder in spring-context.xml. My spring-context.xml is:
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="ignoreResourceNotFound" value="true" />
<property name="ignoreUnresolvablePlaceholders" value="true" />
<property name="searchSystemEnvironment" value="true" />
<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
<property name="locations" ref="propertyConfigurerFiles" />
</bean>
<bean id="propertyConfigurerFiles" class="java.util.ArrayList">
<constructor-arg>
<list>
<value>/WEB-INF/properties/common.properties</value>
<!--In Developemnet Enviroenment it will be dev.properties-->
<value>/WEB-INF/properties/${spring.profiles.active}.properties</value>
<!--External Property File Location as a Placeholder-->
<value>${app.config.batch.location}</value>
</list>
</constructor-arg>
</bean>
And my dev.properties is:
app.config.batch.location=E:/project/properties/config.properties
My problem is that is ${app.config.batch.location} placeholder is not
resolved in spring-context.xml and its trying to load file
${app.config.batch.location} in place of
E:/project/properties/config.properties.
I hope I explained the problem well. Please help!
Thanks in Advance!!!
You need to create bean of class PropertyPlaceHolderConfigurer.
Not just some ArrayList bean. Why do you think you need this ArrayList bean?
It seems you are using spring profiles, instead of messing with initialization time property value binding what you can do is ...
1) read the property file(profile's)
/WEB-INF/properties/${spring.profiles.active}.properties
2) create a java class that can read these property values. (don't forget to use spring profiles interfacing class)
3) as you are trying to read a property file whose location is embedded in property file(step-1), object created at step-2 will give value for key <value>${app.config.batch.location}</value>
now you can load this property file using available file reader class.
4) create Properties object and access the values in it.
Note:: if any of your bean initialization depends on key-value read at step-4, do initialization manually or create your ***custom class(servlet) that get loaded before any other class (even spring's DispactherServlet).
I am a begginer in Spring and encountered the following problem.
I have the following files:
app.properties
applicationContext.xml
web.xml
Within app.properties I have the value app.env=dev
In applicationContext.xml:
<bean class="org.springframework.web.context.support.ServletContextPropertyPlaceholderConfigurer">
<property name="ignoreResourceNotFound" value="true" />
<property name="location">
<value>app.properties</value>
</property>
</bean>
I want to use the app.env from the properties file in web.xml like this:
<context-param>
<param-name>ENV</param-name>
<param-value>${app.env}</param-value>
</context-param>
I am using ${app.env} without problems in applicationContext.xml.
I have found discussions that state you can push values into web.xml from a properties file but I have also found people saying it is not possible (usually older posts).
The issue is the placeholder ${app.env} in web.xml is not replaced by the value from the properties file. Is it possible to do it? If so what am I missing.
I have configured a config.xml file choosing the appropriate properties file depending on environment. I am running this as a Spring Boot app with Apache Camel.
The config looks like this.
<bean id="properties"
class="org.apache.camel.component.properties.PropertiesComponent">
<property name="locations" ref="locations" />
</bean>
<bean id="bridgePropertyPlaceholder"
class="org.apache.camel.spring.spi.BridgePropertyPlaceholderConfigurer">
<property name="locations" ref="locations" />
<property name="ignoreUnresolvablePlaceholders" value="true" />
</bean>
<beans profile="dev">
<util:list id="locations">
<value>classpath:config/users.properties</value>
<value>classpath:config/application.properties</value>
<value>classpath:config/application-dev.properties</value>
</util:list>
<beans profile="test">
<util:list id="locations">
<value>file:${project.dir}/config/users.properties</value>
<value>file:${project.dir}/config/application.properties</value>
</util:list>
When using the test profile I want to use the external files defined in the config (because I dont want to commit username/password to repo). That seems to work okay.
However, my users.properties file contains:
username=myusername
password=mypassword
and my application.properties contains:
loginParameters=username=${username}&password=${password}
when running java -jar myjar.jar --spring.profiles.active=test I encounter:
java.lang.IllegalArgumentException: Could not resolve placeholder 'username' in string value '${username}&password=${password}'
It clearly loads the properties files because it states:
Loading properties file from URL: file:...../users.properties
Loading properties file from URL: file:...../application.properties
Bridging Camel and Spring property placeholder configurer with id: bridgePropertyPlaceholder
...
And then the exception occurs. How can I resolve the issue where the application.properties file doesn't recognize my properties defined in users.properties? Everything works okay when running the dev-profile.
in your application properties, use $simple{username} and $simple{password} to tell Camel to put the values there.
in my web.xml i want to read the welcome file from property file
something like:
<welcome-file-list>
<welcome-file>${home.page}</welcome-file>
</welcome-file-list>
i have propertyPlaceholderConfigurer configured:
<bean id="propertyPlaceholderConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:messages/application.properties</value>
</list>
</property>
</bean>
is there's additional param should be added to web.xml, or another bean needs to be defined or what ?
also i have another xml file on the same level of web.xml (under WEB-INF direclty)
can i read from property file in it in the same way ?
please advise.
It doesn't work like that; the web.xml file is completely unrelated to Spring.
What you could do is have a hard-coded welcome file, and inside that file, redirect to something defined in the Spring configuration, retrieving the page by grabbing the Spring context manually.
I want to pass the WSDL url for an internal web service into my Spring beans.xml dynamically, using a PropertyPlaceHolderConfigurer.
Here's the scenario:
My web application is deployed in WebLogic 10.3.
The WSDL url is contained in a properties file that is located outside my application (directly under the corresponding domain folder, while my application is inside the autodeploy folder). I set the location of this properties file in my domain's setDomainEnv.cmd file like below:
set JAVA_PROPERTIES=%JAVA_PROPERTIES% %CLUSTER_PROPERTIES% -Dproperty.file.path.config=%DOMAIN_HOME%\Service.properties
This is what my Service.properties file contains:
Service.WSDL.PATH=http://localhost:8088/mockServiceSoap?WSDL
My Spring beans.xml configuration:----
<bean id="file.path" class="java.lang.System" factory-method="getProperty">
<constructor-arg index="0"><value>property.file.path.config</value></constructor-arg>
</bean>
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" ref="file.path"/>
</bean>
<bean id="myServiceId" class="com.test.service.ServiceImpl">
<property name="myServiceSoap">
<ref bean="myService"/>
</property>
</bean>
<bean id="myService" class="org.springframework.remoting.jaxws.JaxWsPortProxyFactoryBean">
<property name="serviceInterface" value="com.test.service.ServiceSoap"/>
<property name="wsdlDocumentUrl" value="${Service.WSDL.PATH}"/>
</bean>
I enabled DEBUG log specifically for PPC and this is what I saw in my application log:
INFO org.springframework.beans.factory.config.PropertyPlaceholderConfigurer 178 - Loading properties file from URL [file:D:/bea10.3/user_projects/domains/my_domain/Service.properties]
So, it seems that although the Service.properties file is getting loaded by PPC, the ${Service.WSDL.PATH} is NOT getting replaced.
What am I doing wrong here?
Also, how can I find out if PPC tried replacing the value of the placeholder and with what value? I was hoping the log file would contain that info but there was nothing there.
Any help is appreciated.
I've figured out, that PropertyPlaceholderConfigurer needs to be declared first in the application Context file, otherwise there's no guarantee of the load order. It took me a few hours to realize this.
Try moving the "file.path" bean into the PropertyPlaceHolderConfigurer's location property.
