6.查看

springboot并不推荐使用jsp，不推荐!

1.首先idea快速构建一个springboot项目。

我们需要手动添加WEB-INF这些文件夹。

2.配置视图解析

application.properties

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

server.port=8081

3.编写一个实体类，用户传数据。

package xyz.xioaxin12.springboot.student;

public class Student {
    private Integer id;
    private String name;
    private int age;

    public Student() {
    }

    public Student(Integer id, String name, int age) {
        this.id = id;
        this.name = name;
        this.age = age;
    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    @Override
    public String toString() {
        return "Student{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", age='" + age + '\'' +
                '}';
    }
}

4.controller视图层

注意注解是@Controller,可以直接返回一个视图，由于已经设置了视图的”前后缀”，return便是返回到WEB-INF/jsp/index.jsp页面。

package xyz.xioaxin12.springboot.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import xyz.xioaxin12.springboot.student.Student;

import java.util.ArrayList;
import java.util.List;

@Controller
public class JspContreller {

    @RequestMapping("/show")
    public String Show(Model model){
        List<Student> students = new ArrayList<>();
        students.add(new Student(1,"小信",33));
        students.add(new Student(2,"小田",25));
        students.add(new Student(3,"小夏",19));
        students.add(new Student(4,"小方",23));

        model.addAttribute("student",students);
        return "index";
    }

}

5.jsp页面的编写

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
    <table border="1" width="600px" style="margin: auto;text-align: center">
        <tr>
            <th>id</th>
            <th>姓名</th>
            <th>年龄</th>
        </tr>
        <c:forEach items="${student}" var="s">
            <tr>
                <td>${s.id}</td>
                <td>${s.name}</td>
                <td>${s.age}</td>
            </tr>
        </c:forEach>
    </table>
</body>
</html>

用到了jsp中的jstl，所以我们需要提前在pom.xml中引入下列依赖。

        <!-- 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>
