二、foreach案例

1.创建项目

2. 创建Student.java

package cn.kgc.pojo;

/**

 * Created by Administrator on 2019/3/8.

 */

public class Student {

    private Integer sid;

    private String sname;

    private String subject;

    private Double score;

    public Student() {

    }

    public Student(Integer sid, String sname, String subject, Double score) {

        this.sid = sid;

        this.sname = sname;

        this.subject = subject;

        this.score = score;

    }

    public Integer getSid() {

        return sid;

    }

    public void setSid(Integer sid) {

        this.sid = sid;

    }

    public String getSname() {

        return sname;

    }

    public void setSname(String sname) {

        this.sname = sname;

    }

    public String getSubject() {

        return subject;

    }

    public void setSubject(String subject) {

        this.subject = subject;

    }

    public Double getScore() {

        return score;

    }

    public void setScore(Double score) {

        this.score = score;

    }

    @Override

    public String toString() {

        return "Student{" +

                "sid=" + sid +

                ", sname='" + sname + '\'' +

                ", subject='" + subject + '\'' +

                ", score=" + score +

                '}';

    }

}

Student.java

3.创建StudentController.java

package cn.kgc.controller;

import cn.kgc.pojo.Student;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;

import org.springframework.web.servlet.ModelAndView;

import java.util.ArrayList;

import java.util.List;

@RequestMapping("/student")

@Controller

public class StudentController {

    @RequestMapping("/getData.do")

    public ModelAndView getData(ModelAndView modelAndView){

        //挂载对象或数值

        List<Student> list=new ArrayList<Student>();

        list.add(new Student(1,"镇长","java",99.00));

        list.add(new Student(2,"老村长","java",100.00));

        list.add(new Student(3,"村支书","java",88.00));

        modelAndView.addObject("list",list);

        Student student=new Student(1,"holly","java",99.00);

        modelAndView.addObject("stu",student);

        modelAndView.addObject("title","学生信息列表");

        //指定视图

        modelAndView.setViewName("index");

      return modelAndView;

    }

}

StudentController.java

4.创建index.html页面

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml"

            xmlns:th="http://www.thymeleaf.org">

<head>

    <meta charset="UTF-8">

    <title>Title</title>

</head>

<body>

   <h1 th:text="${title}">KD42</h1>

   <p>学号:<span th:text="${stu.sid}">1</span></p>

   <p>姓名:<span th:text="${stu.sname}">张三</span></p>

   <p>科目:<span th:text="${stu.subject}">JAVA</span></p>

   <p>分数:<span th:text="${stu.score}">100</span></p>

  <table>

      <tr>

          <td>学号</td>

          <td>姓名</td>

          <td>科目</td>

          <td>成绩</td>

      </tr>

      <tr th:each="i:${list}">

          <td th:text="${i.sid}">1</td>

          <td th:text="${i.sname}">叶杨</td>

          <td th:text="${i.subject}">oracle</td>

          <td th:text="${i.score}">100</td>

      </tr>

  </table>

</body>

</html>
