Jsp 未在 spring 引导应用程序中由 Jersey 编译

Question

我正在尝试使用 Jersey 设置 spring 启动应用程序。其余 API 工作正常，但视图 (jsp) 在浏览器上呈现为纯文本。我尝试在我的依赖项中包含 jstl，一旦我包含它；服务器开始返回空白响应。

请让我知道我在这里遗漏了什么。

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";
    }
}

你好JSP控制器

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

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
  <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

下面是我尝试访问 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：

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]

将 spring 引导版本更改为 1.5.12 使 JSP 为我工作。 spring boot 2.0.1 可能有问题下面是 pom.xml

Jsp 未在 spring 引导应用程序中由 Jersey 编译

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

jsp

jersey-2.0

spring-boot

spring-jersey
