SpringBoot整合jsp
1、创建项目
2、修改pom文件，添加坐标。将jdk版本改为1.7，添加启动器
<!-- 修改jdk版本 -->
<properties>
<java.version>1.7 </java.version>
</properties>
<!-- springboot启动器 -->
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- jstl -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
<!-- jasper -->
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
</dependencies>
3、创建配置文件application.properties
spring.mvc.view.prefix=/WEB-INF/jsp/ //前缀 spring.mvc.view.suffic= .jsp //后缀
4、创建controller和User类
package com.zhu.controller;
@Controller //做视图跳转，不可用RestController
public class UserController {
/*
* 处理请求，产生数据
*/
@RequestMapping("/showUser")
public String showUser(Model model) {
ArrayList<User> list = new ArrayList<>();
list.add(new User("aa",1,1));
list.add(new User("bb",2,2));
list.add(new User("cc",3,3));
list.add(new User("dd",4,4));
//将list传到jsp当中，需要一个Model对象，因此参数中多了一个Model型参数
model.addAttribute("list",list);
//跳转视图
return "userList";
}
}
package com.zhu.pojo;
public class User {
private String username;
private Integer userid;
private Integer userage;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public User() {
super();
}
public User(String username, Integer userid, Integer userage) {
super();
this.username = username;
this.userid = userid;
this.userage = userage;
}
public Integer getUserid() {
return userid;
}
public void setUserid(Integer userid) {
this.userid = userid;
}
public Integer getUserage() {
return userage;
}
public void setUserage(Integer userage) {
this.userage = userage;
}
}
5、建立jsp jsp文件要在src/main中新建文件夹webapp，再新建文件夹jsp，然后再创建jsp文件
遇到错误，错误原因：<c:forEach item="${list} " var = "user">中，${}后很多了个逗号，
导致异常：Property [userid] not found on type [java.lang.String]] with root cause出现，
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<table border="1" align = "center" width = "50%">
<tr>
<th>ID</th>
<th>Age</th>
<th>Name</th>
</tr>
<c:forEach item="${list}" var = "user">
<tr>
<td>${user.userid}</td>
<td>${user.username}</td>
<td>${user.username}</td>
</tr>
</c:forEach>
</table>
</body>
</html>
6、创建启动类
package com.zhu;
@SpringBootApplication public class App { public static void main(String[] args) { SpringApplication.run(App.class, args); } }
