I am able to run this as spring boot war that uses embeded tc.
In another thread it said use tomcat 9. I am using 10. Still getting the error.
My Spring boot App class:
package pra.learn.tcjardemo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
#SpringBootApplication
#RestController
public class TcjardemoApplication extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(TcjardemoApplication.class);
}
#GetMapping("/show")
public static String getShow(){
return "Show is the problem";
}
// public static void main(String[] args) {
// SpringApplication.run(TcjardemoApplication.class, args);
// }
}
Not sure what am i missing.
So, I deployed it on tc9 and it worked. Why isn't the same war working on tc10?

So I've got a simple spring boot app, #SpringBootApplication, a stub #Configuration and a #RestController all in the same package. Spring-boot-web-starter is there and the webserver comes up fine, actuator endpoints and all. But I cannot for the life of me get the app to pick up the #RestControllers.
enter image description here
Main.class:
package com.iglossolalia.munin;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class Main {
public static void main(String[] args) {
SpringApplication.run(MuninContext.class, args);
}
}
MuninContext.class:
package com.iglossolalia.munin;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.Configuration;
#Configuration
#EnableAutoConfiguration
public class MuninContext {
}
MuninService.class:
package com.iglossolalia.munin;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class MuninService {
private static final Logger LOG = LoggerFactory.getLogger(MuninService.class);
public MuninService() {
LOG.info("Started MuninService");
}
#GetMapping("/health")
public String healthCheck() {
return "pong";
}
}
Tried explicitly adding the rest controller to the component scan with no luck there.
You have no #ComponentScan annotation in your MuninContext. Actually you can write SpringApplication.run(Main.class, args) in main method as Spring Initializr generate by default, you don't really need your context, because #SpringBootApplication work as configuration and contains #EnableAutoConfiguration, #ComponentScan, and some other annotations. Otherwise, as you pass your config class as argument in SpringApplication.run method, annotation #SpringBootApplication in Main class has no effect
I am trying to execute my new Spring Boot application.
The first two classes are:
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class UbbioneApplication {
public static void main(String[] args) {
SpringApplication.run(UbbioneApplication.class, args);
}
}
then the servlet Initializer class
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
public class ServletInitializer extends SpringBootServletInitializer {
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(UbbioneApplication.class);
}
}
But when I am used to run my application by writing mvn spring-boot:run in the console, I have this message appearing:
Whitelabel Error Page
Could you help me please how to resolve this issue?
Thanks in advance.
I think I have an answer:
I created a controller to my application and I updated my code as following:
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
#Configuration
#EnableAutoConfiguration
#ComponentScan(basePackages = {"Name_controller_path"})
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
Then my controller will look like this:
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class Appcontroller {
#RequestMapping(value = "/home", method = RequestMethod.GET)
String home() {
return "home";
}
}
Then use this path to view your execution: http://localhost:8080/home.
I am working on a reactjs project and I just did a yarn build and moved the contents into the Java project.
my-project\complete\src\main\resources\static
but when I view the project from the Java site -- localhost:8080 -- I get a ton of 404 errors
logo.a67f8998.png:1 GET http://localhost:8080/static/media/logo.a67f8998.png
registerServiceWorker.js:77 GET http://localhost:8080/service-worker.js 404
-beefeater.78e4414b.jpg:1 GET http://localhost:8080/static/media/-beefeater.78e4414b.jpg 404 ()
For this project I am mostly acting as a frontend dev - Where do I make the required changes to get the routing correct for these files?
my Application.java file looks like this - when I uncomment the code I get told to remove the #overide?
//import java.util.Date;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
/**
* Hello world!
*
*/
#SpringBootApplication
public class Application implements CommandLineRunner {
//#Autowired
//private AccountRepository accountRepository;
/**
* #param args
*/
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
#Override
public void run(String... arg0) throws Exception {
}
/*
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/static/**")
.addResourceLocations("classpath:/static/");
}*/
}
I've tried to add a config file to sort this out.. do I need to import it in the application.java?
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
//#Configuration
#EnableWebMvc
#WebAppConfiguration
public class Configuration extends WebMvcConfigurerAdapter {
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry
.addResourceHandler("/static/**")
.addResourceLocations("classpath:/static/");
}
}
You're missing #WebMvcAutoConfiguration annotation I think
I'm currently working with SpringBootApplications, I have two differets #SpringBootApplication , one for Web Application, and a CommandLineRunner .
The problem is, no matter which of them I execute, it tries to run both of the applications.
package com.ws;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.context.annotation.Configuration;
#EnableAutoConfiguration
public class Init extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Init.class);
}
/**
* Main method.
*
* #param args String[].
* #throws Exception Exception.
*/
public static void main(String[] args) throws Exception {
SpringApplication.run(Init.class, args);
}
And this is my other InitBatch.java :
package com.batch;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class InitBatch implements CommandLineRunner {
#Autowired
private Batch batch;
#Override
public void run(String... args) throws Exception {
batch.processFiles();
}
public static void main(String[] args) throws Exception {
SpringApplication.run(InitBatch.class, args);
}
}
If I run the CommandLineRunner app, after it is executed, continues to load the Web App.
I need to be able to run each of them separately from each one. But I don't know how to configure this.
Thanks!
the spring docs say:
SpringBootApplication: This is a convenience annotation that is equivalent to declaring #Configuration, #EnableAutoConfiguration and #ComponentScan.
You should only ever add one #EnableAutoConfiguration annotation. We generally recommend that you add it to your primary #Configuration class.
so effectively you're adding 2 EnableAutoConfiguration annotations which just isn't allowed by spring boot. I would suggest using spring Profiles to achieve what you need.
Due to project requirements I have to deploy a Spring application to a server incapable of running Tomcat and only capable of running WildFly. When I had a very simple project running on Tomcat and the root URL was hit (localhost:8080) it rendered my index.html. Since migrating to WildFly and refactoring the structure of my project, localhost:8080 no longer renders the index.html but I can still reach other URLs.
I've tried to implement a jboss-web.xml file under BrassDucks/src/main/webapp/WEB-INF/jboss-web.xml like this:
<jboss-web>
<context-root>Brass-Ducks</context-root>
</jboss-web>
Where Brass-Ducks is the artifactID but to no avail.
Consider my ApplicationConfig.java
package brass.ducks;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
#Configuration
#ComponentScan
#EnableAutoConfiguration
public class ApplicationConfig extends SpringBootServletInitializer{
public static void main(String[] args) {
SpringApplication.run(ApplicationConfig.class, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(applicationClass);
}
private static Class<ApplicationConfig> applicationClass = ApplicationConfig.class;
}
#RestController
class GreetingController {
#RequestMapping("/hello/{name}")
String hello(#PathVariable String name) {
return "Hello, " + name + "!";
}
}
and consider my Controller.java
package brass.ducks.application;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
#RestController
#RequestMapping("/")
public class Controller {
#RequestMapping("/greet")
#ResponseBody
public String greeting() {
return "Hello, there.";
}
}
And finally should it be relevant, my folder structure:
localhost:8080/greet returns "Hello, there" and localhost:8080/hello/name returns "Hello name". How can I fix this?
Depending on your exact configuration something along the lines of this should work:
#Controller
public class LandingPageController {
#RequestMapping({"/","/home"})
public String showHomePage(Map<String, Object> model) {
return "/WEB-INF/index.html";
}
}
This is going to explicitly map / to index.html.
