这篇博客介绍了如何利用SpringBoot构建一个JSP web应用。首先，导入了必要的SpringBoot依赖，包括web、配置处理器、热加载和Lombok。然后创建了webapp目录结构，并编写了`index.jsp`页面。在`application.yml`中配置了JSP的视图解析路径。最后，创建了一个简单的JspController，用于展示`index.jsp`并传递参数。

导入依赖

 <!-- SpringBoot Web -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!-- SpringBoot 加载配置文件 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-configuration-processor</artifactId>
        </dependency>
        <!-- SpringBoot 热加载 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <optional>true</optional>
        </dependency>
        <!-- SpringBoot lombok -->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.18.14</version>
            <scope>provided</scope>
        </dependency>
        <!-- SpringBoot 启动器 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <!-- jsp 核心依赖 -->
        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-jasper</artifactId>
        </dependency>
		<!-- jstl 表达式 -->
        <!-- https://mvnrepository.com/artifact/javax.servlet/jstl -->
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jstl</artifactId>
        </dependency>

创建webapp 文件及子文件 WEB-INF(目录层级一定要正确，和java与resources同级) 下面创建 index.jsp

<%@ page import="java.util.*" contentType="text/html; charset=UTF-8" %>
<html>
<head>
    <meta charset="UTF-8">
    <title></title>
</head>
<body>
    <h1>hello.123456+${name}</h1>
</body>
</html>

3、在application.yml 文件配置jsp

spring:
# jsp
  mvc:
    view:  # 视图前缀和后缀
      prefix: /WEB-INF/
      suffix: .jsp

4、创建JspController 控制器类

package com.testspringboot.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;

@Controller
public class JspController {

    @GetMapping("/index")
    public String index(Model model) {
        model.addAttribute("name", "一千二白三世四生五谷六畜");
        return "index";
    }
}
