最近在学习SpringBoot，看到SpringBoot整合jsp，顺带记录一下。
1、创建一个SpringBoot项目
点击Next
注意：packaging选中War，点击Next
Webà选中Web，点击Next
输入项目名，点击finish，到此springBoot项目创建完成，
2、项目结构如下：
根据目录创建controller，然后创建JspController类；
main下创建webapp\WEB-INF\jsp\index.jsp
3、Resources文件下，application.properties文件中添加内容：
|
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
|
Pom.xml内容：
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>

<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.2.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->

<artifactId>test</artifactId>

<packaging>war</packaging>

<description>Demo project for Spring Boot</description>
<properties>

<plugin>

<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>

4、JspController中内容，注解必须为@Controller，return结果为页面名称
package com.springboot.test.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class JspController {
@RequestMapping("/index")
public String jspIndex(){
System.out.println("SpringBoot整合jsp。。。");
return "index";
}
}
|
Index,jsp文件中只写了简单的输出
<body>
<h3>SpringBoot整合jsp...</h3>
</body>
|
运行TestApplication，控制台没报错，则启动成功。
5、打开页面，输入地址，跳转到jsp页面
项目module中整合，与创建springboot项目同样的方式创建module，在最外层src\main下创建webapp\WEB-INF\jsp\index.jsp
最终目录结构：
