I want to override properties defined in application.properties through cmd with existing other in application.properties , but #Scheduled only allows to provide predefined values.
What I need is to pass the argument for #Scheduled through command line which already exists in application.properties and It will going to change the default value defined in #Scheduled.
My question is that when I am executing jar file from cmd It is taking value present in #Scheduled at the time of build. It is not overriding the existing value #Scheduled value. I want to override value as per user need.
spring code
#SpringBootApplication
#EnableScheduling
public class PSchedularApplication {
public static void main(String[] args) {
for(String s : args)
System.out.println("arguments passed=>"+s);
SpringApplication application = new SpringApplication(PSchedularApplication .class);
if(!(args).equals(null))
{
application.setAddCommandLineProperties(true);
}
application.run(args);
}
}
#Component
public class TaskSchedular {
#Scheduled(cron="${cronExpression}")
public void taskScheduling()
{
System.out.println("Welcome to task schedular " + new java.util.Date());
moveFile();
}
}
Application.properties
cronExpression=0 0/1 * * * *
pzsc.poll.cron.weekly=0 0/2 * * * *
pzsc.poll.cron.daily=0/30 * * * * *
in cmd
java -jar PSchedular-0.0.1-SNAPSHOT.jar --cron=cronExpression
There's a couple ways of doing this, but one way I can think of is to use externalized application properties file. See https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#boot-features-external-config-files for more specific details.
You would have your application.properties (under src/main/resources) with the default property cronExpression. But when you invoke the JAR, you could pass in a system property to tell Spring where an additional properties file is with possible overrides for that cronExpression property.
java -jar <jar_name> -Dspring.config.additional-location=my-other-file.properties
java -jar -Dserver.port=9999 your_jar_file.jar
Please take a look at this thread. There's a many example.

I am writing a custom Info Contributor. I have a properties file that is generated during the build process in target/classes folder.
How Can I use this generated file in the custom info contributor.
I checked the below code for GitInfoContributor
public class GitInfoContributor extends InfoPropertiesInfoContributor<GitProperties> {
public GitInfoContributor(GitProperties properties) {
this(properties, Mode.SIMPLE);
}
public GitInfoContributor(GitProperties properties, Mode mode) {
super(properties, mode);
}
#Override
public void contribute(Info.Builder builder) {
builder.withDetail("git", generateContent());
}
#Override
protected PropertySource<?> toSimplePropertySource() {
Properties props = new Properties();
copyIfSet(props, "branch");
String commitId = getProperties().getShortCommitId();
if (commitId != null) {
props.put("commit.id", commitId);
}
copyIfSet(props, "commit.time");
return new PropertiesPropertySource("git", props);
}
/**
* Post-process the content to expose. By default, well known keys representing dates
* are converted to {#link Instant} instances.
* #param content the content to expose
*/
#Override
protected void postProcessContent(Map<String, Object> content) {
replaceValue(getNestedMap(content, "commit"), "time", getProperties().getCommitTime());
replaceValue(getNestedMap(content, "build"), "time", getProperties().getInstant("build.time"));
}
}
I am not able to figure out how the git properties are being injected to GitProperties class here ?
I need to do the same for my custom info contributor using my properties file.
In addition to a git contributor, Spring boot also comes with a EnvironmentInfoContributor. This contributor automatically includes all application properties starting with info.*.
So the easiest solution is to make sure your custom properties all start with info.* and to treat your custom properties file as an additional application properties file. This can be done by providing the spring.config.additional-location VM argument. For example:
java -jar -Dspring.config.additional-location=classpath:custom-properties myApp.jar
Now you only have to enable the environment info contributor by setting:
management.info.env.enabled=true
If this isn't possible, you can indeed write your own contributor. One way of doing so is by programmatically reading your properties and converting it to a Map<String, String>. Once that's done, you can call the Info.Builder.withDetails(..) method with your Map (see the source code of EnvironmentInfoContributor).
Below showing the project structure
Core Project
|-config project
|
|-Service project
After building the core project we get Service.jar file.
While running the service.jar am passing spring.config.additional.location as command line argument.
java -jar Service-1.0.jar --spring.config.additional-location=C:/Users/Administrator/Desktop/Springboot/
above spring.config.additional.location path having application.property file and some xml files.
I can able to read application property file in service project ,following logic
Application.propertes
external.config=C:/Users/Administrator/Desktop/Springboot/config/
Mian Class
#ImportResource(locations = {
"${external.config}"+"/spring/service-config.xml",
"${external.config}"+"/spring/datasource-config.xml"
})
public class ServiceMain {
public static void main(String[] args) {
ConfigurableApplicationContext applicationContext = new SpringApplicationBuilder(ServiceMain.class)
.build()
.run(args);
for (String name : applicationContext.getBeanDefinitionNames()) {
}
}
}
Similar kind of logic applied in config project is given below,its not working
#Configuration
public class ConfigurationFactory
{
#Value("${external.config}")
public String extConfPath;
public String REQ_CONF = extConfPath+"/Configuration.xml";
public static final String FILTER_XML_CONF = extConfPath+"/DocFilter.xml";
}
Is there any better way to do this? How can i read external application.properties in config project
Do we have any better way to do this in spring boot
As you are cleary developing a distributed web system the best practice is to used externalised configuration used by your different services allowing you to update settings without redeployment. Take a look at Spring Cloud Config
As mentioned in the title I have two applications with two different logging configurations. As soon as I use springs logging.file setting I can not seperate the configurations of both apps.
The problem worsens because one app is using logback.xml and one app is using log4j.properties.
I tried to introduce a new configuration parameter in one application where I can set the path to the logback.xml but I am unable to make the new setting work for all logging in the application.
public static void main(String[] args) {
reconfigureLogging();
SpringApplication.run(IndexerApplication.class, args);
}
private static void reconfigureLogging() {
if (System.getProperty("IndexerLogging") != null && !System.getProperty("IndexerLogging").isEmpty()) {
try {
JoranConfigurator configurator = new JoranConfigurator();
configurator.setContext(context);
// Call context.reset() to clear any previous configuration, e.g. default
// configuration. For multi-step configuration, omit calling context.reset().
System.out.println("SETTING: " + System.getProperty("IndexerLogging"));
System.out.println("SETTING: " + System.getProperty("INDEXER_LOG_FILE"));
context.reset();
configurator.doConfigure(System.getProperty("IndexerLogging"));
} catch (JoranException je) {
System.out.println("FEHLER IN CONFIG");
}
logger.info("Entering application.");
}
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
reconfigureLogging();
return application.sources(applicationClass);
}
The above code works somehow. But the only log entry which is written to the logfile specified in the configuration, which ${IndexerLogging} points to, is the entry from logger.info("Entering application."); :(
I don't really like to attach that code to every class which does some logging in the application.
The application has to be runnable as tomcat deployment but also as spring boot application with integrated tomcat use.
Any idea how I can set the path from ${IndexerLogging} as the path to read the configuration file when first configuring logging in that application?
Take a look at https://github.com/qos-ch/logback-extensions/wiki/Spring you can configure the logback config file to use.
I need to change the default location of log4j2 configuration file. I followed the documentation here
https://logging.apache.org/log4j/2.x/manual/webapp.html
But the only file log4j2 can see is log4j2.xml in the classpath. otherwise I get "no log4j2 configuration file found"
I tried:
-1 setting context parameters
-2 setting system property Log4jContextSelector to "org.apache.logging.log4j.core.selector.JndiContextSelector". and using the JNDI selector
as described here
https://logging.apache.org/log4j/2.x/manual/webapp.html#ContextParams
-3 lookups: web, env, sys, ctx and bundle. the first 4 failed only bundle worked but you can only lookup inside the classpath.
-4 set isLog4jAutoInitializationDisabled to true, and I am not sure how to configure the filter in this case. If I include them in the web.xml the app will not deploy.
jar in the project
./WEB-INF/lib/log4j-jcl-2.4.1.jar
./WEB-INF/lib/log4j-core-2.4.1.jar
./WEB-INF/lib/log4j-slf4j-impl-2.4.1.jar
./WEB-INF/lib/log4j-api-2.4.1.jar
In my situation with .propeties file I use code shown below
#Plugin(name = "LogsConfigurationFactory", category = ConfigurationFactory.CATEGORY)
public class CustomLogsConfigurationFactory extends PropertiesConfigurationFactory {
#Override
public Configuration getConfiguration(String name, URI configLocation) {
File propFile = new File("/path_to/log4j2.properties");
return super.getConfiguration(name, propFile.toURI());
}
#Override
protected String[] getSupportedTypes() {
return new String[] {".properties", "*"};
}
}
I think you can change CustomLogsConfigurationFactory on XmlConfigurationFactory, and change return typse in getSupportedTypes method. I hope this will help you.
I have a project and in it I'm using spring-boot-jdbc-starter and it automatically configures a DataSource for me.
Now I added camel-spring-boot to project and I was able to successfully create routes from Beans of type RouteBuilder.
But when I'm using sql component of camel it can not find datasource. Is there any simple way to add Spring configured datasource to CamelContext? In samples of camel project they use spring xml for datasource configuration but I'm looking for a way with java config. This is what I tried:
#Configuration
public class SqlRouteBuilder extends RouteBuilder {
#Bean
public SqlComponent sqlComponent(DataSource dataSource) {
SqlComponent sqlComponent = new SqlComponent();
sqlComponent.setDataSource(dataSource);
return sqlComponent;
}
#Override
public void configure() throws Exception {
from("sql:SELECT * FROM tasks WHERE STATUS NOT LIKE 'completed'")
.to("mock:sql");
}
}
I have to publish it because although the answer is in the commentary, you may not notice it, and in my case such a configuration was necessary to run the process.
The use of the SQL component should look like this:
from("timer://dbQueryTimer?period=10s")
.routeId("DATABASE_QUERY_TIMER_ROUTE")
.to("sql:SELECT * FROM event_queue?dataSource=#dataSource")
.process(xchg -> {
List<Map<String, Object>> row = xchg.getIn().getBody(List.class);
row.stream()
.map((x) -> {
EventQueue eventQueue = new EventQueue();
eventQueue.setId((Long)x.get("id"));
eventQueue.setData((String)x.get("data"));
return eventQueue;
}).collect(Collectors.toList());
})
.log(LoggingLevel.INFO,"******Database query executed - body:${body}******");
Note the use of ?dataSource=#dataSource. The dataSource name points to the DataSource object configured by Spring, it can be changed to another one and thus use different DataSource in different routes.
Here is the sample/example code (Java DSL). For this I used
Spring boot
H2 embedded Database
Camel
on startup spring-boot, creates table and loads data. Then camel route, runs "select" to pull the data.
Here is the code:
public void configure() throws Exception {
from("timer://timer1?period=1000")
.setBody(constant("select * from Employee"))
.to("jdbc:dataSource")
.split().simple("${body}")
.log("process row ${body}")
