【SpringBoot】08.SpringBoot整合jsp

SpringBoot整合jsp

1.修改pom文件加入两个坐标jstl标签库和jasper

<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>
  <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.2.RELEASE</version>
  </parent>
  <groupId>com.dxh</groupId>
  <artifactId>08-spring-boot-view-jsp</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  
    <!-- 修改JDK版本 -->
  <properties>
  	<java.version>1.8</java.version>
  </properties>
  
  <dependencies>
	<!-- Spring Boot 的启动器 -->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
		</dependency>
		
		<!-- jstl标签库-->
		<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>
</project>

2.创建springboot的全局配置文件(位于classpath根目录)，application.properties

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

3.创建controller和pojo

@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",20));
		list.add(new Users(2,"李四",22));
		list.add(new Users(3,"赵武",25));
		//需要一个Model对象
		model.addAttribute("list",list);
		//跳转视图
		return "userList";
	}
}

public class Users {
	private Integer userId;
	private String userName;
	private Integer userAge;
	
	public Users(Integer userId, String userName, Integer userAge) {
		super();
		this.userId = userId;
		this.userName = userName;
		this.userAge = userAge;
	}
	public Integer getUserId() {
		return userId;
	}
	public void setUserId(Integer userId) {
		this.userId = userId;
	}
	public String getUserName() {
		return userName;
	}
	public void setUserName(String userName) {
		this.userName = userName;
	}
	public Integer getUserAge() {
		return userAge;
	}
	public void setUserAge(Integer userAge) {
		this.userAge = userAge;
	}
}

4.创建jsp页面

  • 注意页面位置(application.properties中定义的) src/main/webapp/WEB-INF/jsp/userList.jsp
<%@ 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>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>
