Jsp is not getting compiled by Jersey within a spring boot app


I am trying to setup a spring boot app with Jersey. The Rest API is working fine however the view (jsp) is getting rendered as is as plain text on browser. I tried including jstl in my dependencies , once I include it ; server starts returning blank response.

Please let me know what am I missing here .

Below is my code:

JerseyConfig.java

package com.example.jersey.configuration;

import javax.ws.rs.ApplicationPath;

import org.glassfish.jersey.server.ResourceConfig;
import org.glassfish.jersey.server.mvc.jsp.JspMvcFeature;
import org.springframework.stereotype.Component;

import com.example.jersey.controller.HelloController;
import com.example.jersey.controller.HelloJSPController;

@Component
@ApplicationPath("/jersey")
public class JerseyConfig extends ResourceConfig
{
    public JerseyConfig()
    {
        property(JspMvcFeature.TEMPLATE_BASE_PATH, "/WEB-INF/jsp");
        register(JspMvcFeature.class);
        register(HelloController.class);
        register(HelloJSPController.class);

    }
}

HelloController.java

package com.example.jersey.controller;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

import org.springframework.stereotype.Component;

@Component
@Path("/hello")
public class HelloController {

    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String hello() {
        return "Hello Jersey with Spring boot";
    }
}

HelloJSPController

package com.example.jersey.controller;

import javax.inject.Singleton;
import javax.servlet.ServletContext;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;

import org.glassfish.jersey.server.mvc.Viewable;
import org.springframework.stereotype.Component;

@Component
@Singleton
@Path("/helloJSP")
public class HelloJSPController {

    @GET
    @Produces(MediaType.TEXT_HTML)
    public Viewable getIt(@Context final ServletContext context) {

        return new Viewable("/index");
    }
}

SpringJerseyApplication.java

package com.example.jersey;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SpringJerseyApplication {

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

application.properties

spring.jersey.servlet.load-on-startup=1
spring.jersey.type=filter
logging.level.root=INFO

index.jsp

Below is the response I get when I try to access JSP enter image description here

If I uncomment tomcat-embed-jasper, my application doesn't comes up. It throws the following exception:

Caused by: java.lang.NoSuchMethodError: javax.servlet.ServletContext.getVirtualServerName()Ljava/lang/String;
    at org.apache.catalina.authenticator.AuthenticatorBase.startInternal(AuthenticatorBase.java:1186) ~[tomcat-embed-core-8.5.29.jar:8.5.29]

Solution

  • Changing the spring boot version to 1.5.12 makes the JSP working for me. Something is probably broken with spring boot 2.0.1 Below is the pom.xml
