springboot和thymeleaf编写用户管理系统

1.springboot和thymeleaf编写用户管理系统

2.源代码构建

3.通过rest服务

UserController的控制端

package com.dachan.userthymeleaf.controller;

import com.dachan.userthymeleaf.entity.User;
import com.dachan.userthymeleaf.service.UserRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.servlet.ModelAndView;

import java.util.List;

/**
 * auther:大成
 * email: 47160999
 */
@RestController
@RequestMapping("/users")
public class UserController {

    @Autowired
    private UserRepository userRepository;

    /**
     * 从 用户存储库 获取用户列表
     * @return
     */
    private List<User> getUserlist() {
        return userRepository.listUser();
    }

    /**
     * 查询所用用户
     * @return
     */
    @GetMapping
    public ModelAndView list(Model model) {
        model.addAttribute("userList", getUserlist());
        model.addAttribute("title", "用户管理");
        return new ModelAndView("list", "userModel", model);
    }

    /**
     * 根据id查询用户
     * @return
     */
    @GetMapping("{id}")
    public ModelAndView view(@PathVariable("id") Long id, Model model) {
        User user = userRepository.getUserById(id);
        model.addAttribute("user", user);
        model.addAttribute("title", "查看用户");
        return new ModelAndView("view", "userModel", model);
    }

    /**
     * 获取 form 表单页面
     * @return
     */
    @GetMapping("/form")
    public ModelAndView createForm(Model model) {
        model.addAttribute("user", new User());
        model.addAttribute("title", "创建用户");
        return new ModelAndView("form", "userModel", model);
    }

    /**
     * 新建用户
     * @param user
     * @return
     */
    @GetMapping("add")
    public ModelAndView create(User user) {
        user = userRepository.saveOrUpateUser(user);
        return new ModelAndView("redirect:/users");
    }

    /**
     * 删除用户
     * @param id
     * @return
     */
    @GetMapping(value = "delete/{id}")
    public ModelAndView delete(@PathVariable("id") Long id, Model model) {
        userRepository.deleteUser(id);

        model.addAttribute("userList", getUserlist());
        model.addAttribute("title", "删除用户");
        return new ModelAndView("list", "userModel", model);
    }

    /**
     * 修改用户
     */
    @GetMapping(value = "modify/{id}")
    public ModelAndView modifyForm(@PathVariable("id") Long id, Model model) {
        User user = userRepository.getUserById(id);

        model.addAttribute("user", user);
        model.addAttribute("title", "修改用户");
        return new ModelAndView("form", "userModel", model);
    }


}

entity的代码

package com.dachan.userthymeleaf.entity;
import javax.xml.bind.annotation.XmlRootElement;

/**
 * auther: 大成
 */
@XmlRootElement // mediatype 转为xml
public class User {

    private long id; // 用户的唯一标识
    private String name;
    private int age;

    public User() {
    }

    public User(String name, int age) {
        this.name = name;
        this.age = age;
    }
    public long getId() {
        return id;
    }

    public void setId(long 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;
    }

}
