SpringBoot集成使用JSP

　　项目结构

　　pom.xml

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>

            </plugin>

    </build>

</project>

　　application.properties 配置视图前缀和后缀

server.port=8081
server.servlet.context-path=/demo

spring.mvc.view.prefix=/
spring.mvc.view.suffix=.jsp

　　在src/main下创建一个webapp目录，然后在该目录下新建jsp页面

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">
    
    <title>My JSP 'index.jsp' starting page</title>
    <meta http-equiv="pragma" content="no-cache">
    <meta http-equiv="cache-control" content="no-cache">
    <meta http-equiv="expires" content="0">    
    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
    <meta http-equiv="description" content="This is my page">
    <!-- <link rel="stylesheet" type="text/css" href="styles.css"> -->
  </head>
  
  <body>
    msg: ${msg}
  </body>
</html>

　　IndexController

package com.oy.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class IndexController {

    @RequestMapping("/hello/jsp")
    public String hello(Model model) {
        model.addAttribute("msg", "springboot集成jsp");
        return "test";
    }
    
}

　　启动springboot，访问 http://localhost:8081/demo/hello/jsp。

　　如果使用IDEA，需要在pom.xml添加，这样IEDA编译时才会把jsp页面编译到对应目录

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
    
    <resources>
        <resource>
            <directory>src/main/java</directory>
            <includes>
                <include>**/*.xml</include>
            </includes>
        </resource>
        <resource>
            <directory>src/main/resources</directory>
            <includes>
                <include>**/*.*</include>
            </includes>
        </resource>
        <resource>
            <directory>src/main/webapp</directory>
            <targetPath>META-INF/resources</targetPath>
            <includes>
                <include>**/*.*</include>
            </includes>
        </resource>
    </resources>
    
</build>
