1. Spring boot 整合 JSP

创建Springboot 项目

1.1 导入必须的依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-jasper</artifactId>
    <scope>provided</scope>
</dependency>
<!--使用jstl 表达公式-->
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
</dependency>

1.2 配置web 目录

在 main 目录下配置 webapp/WEB-INF/jsp 目录用于存放jsp 页面。并配置webapp 为web 目录。

1.3 配置视图解析

方式一、在application.properties 中配置

spring.mvc.view.prefix=WEB-INF/jsp/
spring.mvc.view.suffix=.jsp

方式二、创建配置类(实现WebConfigurer)

@Configuration
public class WebMVCConfig implements WebMvcConfigurer {
    @Override
    public void configureViewResolvers(ViewResolverRegistry registry) {
       registry.jsp("WEB-INF/jsp/",".jsp");
    }
}

1.4 配置controller

@Controller
public class HelloController {
    @GetMapping("/hello")
    public String hello(Model model){
        model.addAttribute( "msg","Hello Spring boot + jsp" );
        return "hello";
    }
}

1.5 配置页面

hello.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Jsp</title>
</head>
<body>
<h1>01.jsp</h1>
<h1>${msg}</h1>
</body>
</html>
