Spring Boot 404 on REST API calls only
Question
Issue:
I'm working on a Spring-Boot Web Application that needs to be deployed on tomcat (WAR file). When running the application as Java (right click application.java file and run as Java in Eclipse) or running via mvnw.cmd spring-boot:run, everything works PERFECTLY (home page shows, all CRUD operations work).
When I export a WAR file and deploy to tomcat, my static web content and homepage still load fine, but any API calls return a 404 response.
This project was created using Spring Initializr. I've tried exporting via Eclipse war export, and mvnw.cmd package. Placed the WAR file in webapps directory on server and ran.
Directory structure:
Application file:
package com.blank.systemshare;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class SystemshareApplication {
public static void main(String[] args) {
SpringApplication.run(SystemshareApplication.class, args);
}
}
ServletInitializer:
package com.blank.systemshare;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
public class ServletInitializer extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(SystemshareApplication.class);
}
}

Removing the ServletInitializer.java class and updating my application file to the following resolved the issue (extending SpringBootServletInitializer and overriding the configure method). Note that I tried this before, but built the application using both Eclipse and InteliJ. Both times the same issue still occurred. This final time I built using mvnw package and the WAR generated in the target directory worked.
package com.blank.systemshare;
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;
@SpringBootApplication
public class SystemshareApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(SystemshareApplication.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(SystemshareApplication.class);
}
}

Try server.servlet.context-path instead of server.servlet.contextPath .
