我正在尝试使用 Jersey 设置 Spring Boot 应用程序。Rest API 工作正常，但视图（jsp）在浏览器上呈现为纯文本。一旦我包含它，我尝试在我的依赖项中包含 jstl；服务器开始返回空白响应。
请让我知道我在这里缺少什么。
代码结构：
下面是我的代码：
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);
}
}

以下是我尝试访问 JSP 时得到的响应
如果我取消注释 tomcat-embed-jasper，我的应用程序不会出现。它抛出以下异常：
