一、SpringBoot中添加JSP的支持

1、创建Maven web project

SpringBoot之十一：添加JSP支持_web

2、在pom.xml文件中添加依赖

<!-- spring-boot-starter-web: MVC,AOP的依赖包....-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- spring-boot-starter-test: MVC,AOP的测试类包....-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
</dependency>

<!-- 添加fastjson 依赖包:使用这个框架解析json-->
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>fastjson</artifactId>
    <version>1.2.15</version>
</dependency>

<!-- spring-boot-devtools依赖包 -->
<dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-devtools</artifactId>
          <optional>true</optional>
          <scope>true</scope>
</dependency>

<!-- 添加Spring-data-jpa依赖. -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>



<!-- servlet 依赖. -->
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <scope>provided</scope>
</dependency>


<!-- jstl支持 -->
<dependency>
    <groupId>javax.servlet.jsp.jstl</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2</version>
</dependency>



<!-- tomcat 的支持.-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-jasper</artifactId>
    <scope>provided</scope>
</dependency>

3、 配置application.properties支持jsp


########################################################
###JSP
########################################################
# 页面默认前缀目录
spring.mvc.view.prefix=/WEB-INF/jsp/
# 响应页面默认后缀
spring.mvc.view.suffix=.jsp
# 自定义属性，可以在Controller中读取
application.hello=Hello Angel From application

4、编写测试Controller


@Controller
public class JSPController {
    private String hello;

    @RequestMapping("/helloJsp")
    public String helloJsp(Map<String,Object> map){
        System.out.println("HelloController.helloJsp().hello=hello");
        map.put("hello", hello);
        return "index";
    }   
}

5、编写JSP页面

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
    helloJsp
    <hr>
    ${hello}
</body>
</html>

6、启动测试

@SpringBootApplication
public class App {

    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
}
