Spring boot with Java 7 in Weblogic

Question

I have a requirement to deploy the spring boot application in weblogic server 11g. The weblogic server supports only Java 7. Please assist me with the correct spring boot version and I get the following error if I use spring boot version 1.5.6.RELEASE.

On hover the following message gets displayed. "Multiple markers at this line - The type javax.servlet.ServletContext cannot be resolved. It is indirectly referenced from required .class files - The type javax.servlet.ServletException cannot be resolved. It is indirectly referenced from required .class files"

Application.java

package com.example.ap;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.web.WebApplicationInitializer;

@SpringBootApplication
@EnableAutoConfiguration
@ComponentScan({ "com.example.ap" })
public class Application extends SpringBootServletInitializer implements 
WebApplicationInitializer {

public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
}

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder 
builder) {
    return builder.sources(Application.class);
}
}

ResourceController.java

package com.example.ap;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/resource")
public class ResourceController {

    @RequestMapping(method = RequestMethod.GET)
    String readResource() {
        return "hello!";
    }
}

In src/main/webapp/WEB-INF folder, I have weblogic.xml and dispatcherServlet-servlet.xml

I have excluded the embedded tomcat, because I need to deploy it in weblogic. Please help me with finding the issue.

Answer 1

Weblogic 11g(10.3.4) will support servlet 2.5(max). If needed to create an application using servlet 2.5, then web.xml is mandatory. Spring boot's way of configuring the application by using SpringBootServletInitializer, WebApplicationInitializer will be supported from servlet 3.0 onwards only. Thanks for the guidance M.Denium.
