403 Forbidden - Deploying Spring Boot application in Weblogic

Question

I have an application that I'm currently trying to convert to Spring Boot but I'm having issues getting Weblogic configured to run the application. I get 403 Forbidden response on HTTP request.

Any help would be greatly appreciated!

This is my @SpringBootApplication class.

@SpringBootApplication
public class AgisSpringApplication extends SpringBootServletInitializer implements WebApplicationInitializer {

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

    @Override
    public void onStartup(ServletContext context) throws ServletException {

    }
}

This is my weblogic.xml

<?xml version="1.0" encoding="UTF-8"?>
    <wls:weblogic-web-app
        xmlns:wls="http://xmlns.oracle.com/weblogic/weblogic-web-app"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
        http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd
        http://xmlns.oracle.com/weblogic/weblogic-web-app
        http://xmlns.oracle.com/weblogic/weblogic-web-app/1.7/weblogic-web-app.xsd">
    <wls:weblogic-version>12.1.3</wls:weblogic-version>
    <wls:context-root>agis-spring</wls:context-root>
    <wls:container-descriptor>
        <wls:prefer-application-packages>
            <wls:package-name>org.slf4j.*</wls:package-name>
        </wls:prefer-application-packages>
    </wls:container-descriptor>
</wls:weblogic-web-app>

---

And this is my only controller at the moment

@RestController
public class MapController {

    private TemplateService templateService;

    public MapController(TemplateService templateService) {
        this.templateService = templateService;
    }

    @GetMapping("/")
    public String getName() throws Exception {
        return templateService.getTemplate("map.vm");
    }
}

Answer 1

1) your Application.java doesn't look correct. Try this one:

@SpringBootApplication
public class Application 
        extends SpringBootServletInitializer 
        implements WebApplicationInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

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

2) Make sure your weblogic.xml is placed under src/main/webapp/WEB-INF/ .

3) Make sure you package the app into war .

<packaging>war</packaging>

4) Make sure embedded tomcat is disabled.

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
</dependency>

5) I'm not sure if wls:package-name can be specified as wildcart. According to spring-boot documentation it should be like this:

<wls:package-name>org.slf4j</wls:package-name>

6) Build the war artifact by performing mvn clean package .

The .war artifact will be placed to your-app/build/lib . Use this file for deploying into the server.

Hope that some of this hints will solve the problem.
