SpringBoot整合jsp技术

1.修改pom.xml文件

<?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>

    <groupId>cn.ws-h</groupId>
    <artifactId>08-spring-boot-jsp</artifactId>
    <version>1.0-SNAPSHOT</version>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.4.RELEASE</version>
    </parent>

    <dependencies>
        <!--web 启动器-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <!--tomcat对jsp处理的引擎 springboot默认不推荐用jsp-->
        <!--jstl-->
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jstl</artifactId>
        </dependency>
        <!--jasper-->
        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-jasper</artifactId>
        </dependency>

<!-- https://mvnrepository.com/artifact/org.projectlombok/lombok  自动生成-->
<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.18.8</version>
    <scope>provided</scope>
</dependency>

</dependencies> </project>

2.创建springboot的全局配置文件 application.properties

#对jsp文件访问的前缀
spring.mvc.view.prefix=/WEB-INF/jsp
#对jsp文件访问的后缀
spring.mvc.view.suffix=.jsp

3.创建实体

@Data
public class Users {
    private Integer userid;
    private String username;
    private Integer userage;

    public Users(Integer userid, String username, Integer userage) {
        this.userid = userid;
        this.username = username;
        this.userage = userage;
    }

    public Users(int i, String 张三) {
        super();
    }
}

4.创建controller

/**
 * springboot整合jsp
 */
@Controller
public class UserController {
    /**
     * 处理请求，产生数据
     */
    @RequestMapping("/showUser")
    public String showUser(Model model){
        List<Users> list=new ArrayList<>();
        list.add(new Users(1,"张三"));
        list.add(new Users(2,"李四"));
        list.add(new Users(3,"王五"));

        //将list传到jsp中，需要一个Model的对象
        model.addAttribute("list",list);
        //视图的跳转
        return "userList";
    }

}

5.创建jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%--导入标签库--%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<table border="1" align="center" width="50%">
<tr>
    <th>ID</th>
    <th>Name</th>
    <th>Age</th>
</tr>

    <c:forEach items="${list}" var="user">
        <tr>
            <td>${user.userid}</td>
            <td>${user.username}</td>
            <td>${user.userage}</td>
        </tr>
    </c:forEach>
</table>
</body>
</html>

6.创建启动类

/**
 * SpringBoot的启动类
 */
@SpringBootApplication
public class App {
    public static void main(String[] args) {
        SpringApplication.run(App.class,args);
    }
}
