使用 thymeleaf 获取用户列表
1，新建ThymeleafContorllor类
package com.xiang.controller;
import com.xiang.model.User;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
@Controller
@RequestMapping("/xiang")
public class ThymeleafContorllor {
@GetMapping("/user/userList")
public String userList(Model model){
List<User> list = new ArrayList<>();
try {
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
User user = new User();
user.setId(001);
user.setName("小向");
user.setBirthday(format.parse("2000-06-23"));
list.add(user);
user = new User();
user.setId(002);
user.setName("小小");
user.setBirthday(format.parse("2021-11-11"));
list.add(user);
user = new User();
user.setId(003);
user.setName("小小");
user.setBirthday(format.parse("2021-11-11"));
list.add(user);
user = new User();
user.setId(004);
user.setName("小小");
user.setBirthday(format.parse("2021-11-11"));
list.add(user);
model.addAttribute("users",list);
} catch (ParseException e) {
e.printStackTrace();
}
return "userList";
}
}
2，新建model包下新建User类
package com.xiang.model;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import lombok.ToString;
import org.springframework.format.annotation.DateTimeFormat;
import java.util.Date;
@Data
@ToString
@AllArgsConstructor
@NoArgsConstructor
public class User {
//包含：id, name, birthday(日期), salary(浮点类型 工资)等字段
private Integer id;
private String name;
@DateTimeFormat(pattern ="yyyy-MM-dd")
private Date birthday;
private Double salary;
}
3，在resources 下的 templates目录下编写前端代码 文件名为：userList.html
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>userList</title>
</head>
<body>
<h3>用户列表</h3>
<table border="1">
<tr>
<th>编号</th>
<th>姓名</th>
<th>生日（美国时间）</th>
<th>生日(中国时间)</th>
</tr>
<tr th:each="user:${users}">
<td th:text="${user.id}"></td>
<td th:text="${user.name}"></td>
<td th:text="${user.birthday}"></td>
<td th:text="${#dates.format(user.birthday, 'yyyy-MM-dd mm:HH')}"></td>
</tr>
</table>
</body>
</html>
3，运行结果截图
