java
@Data
@NoArgsConstructor
@AllArgsConstructor
@Entity
@ToString
@Table(name = "sys_user")
public class User implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "usr_id")
private Long usrId;
@Column(name = "usr_name")
private String usrName;
@Column(name = "usr_password")
private String usrPassword;
@ManyToOne(targetEntity = Role.class)
@JoinColumn(name = "usr_role_id")
private Role role;
@Column(name = "usr_flag")
private Integer usrFlag;
}继承 JpaRepository 类会自动实现很多内置的方法，包括增删改查。也可以根据方法名来自动生成相关 Sql。
java
public interface UserRepository extends JpaRepository<User,Long>, JpaSpecificationExecutor<User> {
List<User> findByUsrNameAndUsrPassword(String usrName,String usrPassword);
}业务层处理
Service 调用 Jpa 实现相关的增删改查，实际项目中 Service 层处理具体的业务代码。
java
public interface IUserService {
User login(String usrName, String usrPassword);
void saveUser(User user); //适用新增和修改
void deleteUser(Long usrId);
User getUser(Long usrId);
//按条件进行分页查询（动态SQL）
Page<User> findUsers(String usrName, Long roleId, Pageable pageable);
}Controller 负责接收请求，处理完后将页面内容返回给前端。
java
@Controller
public class UserController {
@Resource
private IUserService userService;
@Resource
private IRoleService roleService;
@RequestMapping(value = "dologin")
public String dologin(String usrName, String usrPassword, HttpServletRequest request){
User user = userService.login(usrName,usrPassword);
if(user != null){
request.getSession().setAttribute("loginUser",user);
return "main";
}else {
request.setAttribute("message","登录失败，用户名或密码错误！");
return "login";
}
}
@RequestMapping(value = "logout")
public String logout(HttpSession session){
session.removeAttribute("loginUser");
return "login";
}
@RequestMapping(value = "/user/add")
public String add(Model model){
List<Role> roles = roleService.findAllRoles();
model.addAttribute("roles",roles);
return "user/add";
}
@RequestMapping(value = "/user/save")
public String save(User user){
userService.saveUser(user);
return "redirect:/user/list";
}
@RequestMapping(value = "/user/edit")
public String edit(Long usrId, Model model){
User user = userService.getUser(usrId);
List<Role> roles = roleService.findAllRoles();
model.addAttribute("user",user);
model.addAttribute("roles",roles);
return "user/edit";
}
@RequestMapping(value = "/user/del")
@ResponseBody
public Map del(Long usrId){
userService.getUser(usrId);
Map map = new HashMap();
map.put("delResult","true");
return map;
}
@GetMapping(value = "/user/list")
public String list(Model model, String usrName,
@RequestParam(required = false,defaultValue = "0") Long roleId,
@RequestParam(required = false,defaultValue = "1") int pageIndex){
Sort sort = Sort.by(Sort.Direction.ASC,"usrId");
Pageable pageable = PageRequest.of(pageIndex-1,5,sort);
Page<User> userPager = userService.findUsers(usrName,roleId,pageable);
model.addAttribute("userPager",userPager);
model.addAttribute("usrName",usrName);
model.addAttribute("roleId",roleId);
return "user/list";
}
@RequestMapping(value = "/role/json")
@ResponseBody
public List<Role> findAllRoles(){
return roleService.findAllRoles();
}
}创建Thymeleaf模板
在src/main/resources/templates目录下创建Thymeleaf模板文件
