Springboot process keeps running even after completion in batch mode

Springboot process keeps running even after completion in batch mode - java

I need to run the springboot application in the batch mode. As soon as the processes get finished, the process should exit. I have written a mock code to achieve the same but even after the print statement is completed, the process is not getting completed and I have to manually abort the process.
#SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
ApplicationContext applicationContext = SpringApplication.run(DemoApplication.class, args);
Test test = applicationContext.getBean(Test.class);
test.printTest();
}
}
Test.class :
package com.example.demo.service;
import org.springframework.stereotype.Component;
#Component
public class Test{
public void printTest(){
System.out.println("Test class !");
}
}

It keeps running because you are using an ApplicationContext. You should close the context.
You can use ConfigurableApplicationContext and call the close() method .
ConfigurableApplicationContext applicationContext = SpringApplication.run(DemoApplication.class, args);
Test test = applicationContext.getBean(Test.class);
test.printTest();
applicationContext.close();

Manager throws NullPointerException when using Togglz in Spring Boot application

I'm trying to use Togglz with Spring Boot 2.7.8.
I created this test application to get it up and running:
#SpringBootApplication
public class Testproject2Application {
#Autowired
private static FeatureManager manager;
public static final Feature TOGGLZ_TEST = new NamedFeature("TOGGLZ_TEST");
public static void main(String[] args) {
SpringApplication.run(Testproject2Application.class, args);
if (manager.isActive(TOGGLZ_TEST)) {
TogglzTest togglz = new TogglzTest(manager);
togglz.getTogglzStatus();
}
}
}
#Configurable
public class TogglzTest {
#Autowired
private FeatureManager manager;
#Autowired
public TogglzTest(FeatureManager manager) {
this.manager = manager;
}
public void getTogglzStatus(){
System.out.println("togglzOn is working");
}
}
My pom looks like this:

I set these in application.properties:
togglz.enabled=true
togglz.features.TOGGLZ_TEST.enabled=true
When I run it I get:
Exception in thread "main" java.lang.NullPointerException: Cannot invoke "org.togglz.core.manager.FeatureManager.isActive(org.togglz.core.Feature)" because "com.paulcarron.testproject2.Testproject2Application.manager" is null
at com.paulcarron.testproject2.Testproject2Application.main(Testproject2Application.java:22)
I'm not sure what I should do with manager as nothing about this is mentioned in the Spring Boot Starter documentation.
What should I do to resolve this?

I created the war using mvn clean install or mvn package,and deployed on tomcat server, but getting same 404 not found.
Is there any way I can deploy spring boot application war to tomcat?

Is there any way I can deploy spring boot application war to tomcat?
you can run this command in command prompt.
mvnw spring-boot:run
Note:
May be you should try this url:
http://localhost:8080/test

Spring Boot returns 404

I would like to get a running Springboot Application with Java Backend.
I tried an example application of the web.
I runs on Tomcat. I can install the maven, and run the jar.
I can open the Localhost:8082/ and it returns some .json document.
What i cannot do is to jump to some .html page.
Is there an error in my structure?
Strucure:
HomeController.java
package com.example.demo.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
#Controller
public class HomeController {
#RequestMapping("/home")
public String home() {
return "index";
}
#RequestMapping("/test")
public String test() {
return "test";
}
}
application.properties:
spring.mvc.view.prefix = /views/
spring.mvc.view.suffix = .html
server.port=8082
Application:
#SpringBootApplication
public class BootDemoApplication {
#Autowired
UserRepository userRepository;
public static void main(String[] args) {
SpringApplication.run(BootDemoApplication.class, args);
}
}
}
Error:
Run-Output:
The mapping should work:
2020-12-03 10:09:23.444 INFO 4764 --- [ main] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/test]}" onto public java.lang.String com.example.demo.controller.HomeController.test()

I have tried to change the application.properties into:
spring.mvc.view.prefix = resources/static/views/
and
spring.mvc.view.prefix = /static/views/
this had no effect on the result.
Is there an error, i cannot see?
Thanks

try to add #ComponentScan to the main class#SpringBootApplication #ComponentScan(basePackageClasses = HomeController.class) public class BootDemoApplication {

fix application properties.
spring:
mvc:
view:
suffix : .html
and call url : http://localhost:8082/views/index

You can use thymeleaf as template engine and put your views under the templates folder
src/main/resources > templates,
thanks

Spring Unit Test works in IntelliJ but not when using Maven (Multi Project)

So, I have the following setup:
Project
Module Database
Module Core
Module REST
Core and REST have Database as a Dependency and inside Database is a Configuration Class which connects to the Database on Startup.
Now, when i run each test of this class (default test looks like this:
#RunWith(SpringRunner.class)
#SpringBootTest
public class RestfulApplicationTests {
#Test
public void contextLoads(){}
}
It works when directly ran from IntelliJ.
BUT if i do "clean install" in Maven, Maven cannot find the dependencys. Example pom.xml from my Core Project

I am getting an error in the below java class(ActiveMQQueue cannot be resolved to a type)
src/main/java/sample/activemq/SampleActiveMQApplication.java
package sample.activemq;
import java.util.Queue;
import org.springframework.boot.SpringApplication;

#Bean
public Queue queue() {
return new ActiveMQQueue("sample.queue");
}
public static void main(String[] args) {
SpringApplication.run(SampleActiveMQApplication.class, args);
}
}
Two more classes are there which is exactly same as in Consumer and Producer classes

Finally I resolved my issue
Run mvn dependency:purge-local-repository to remove all dependencies and force a re-download.

Or you can use this in your pom.xml
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jms</artifactId>
<version>5.1.3.RELEASE</version>
</dependency>
