MybatisPlus中插入数据后获取该对象主键值的实现

实体对象 主键IdType要设置为AUTO 表示数据库ID自增

@Data
@EqualsAndHashCode(callSuper = false)
@Accessors(chain = true)
public class Employee implements Serializable {
 private static final long serialVersionUID = 1L;
 @TableId(value = "id", type = IdType.AUTO)
 private Integer id;
 private String lastName;
 private String email;
 private Integer gender;
 private Integer age;
}

返回的实体就会包含主键值

@PostMapping("add")
@ResponseBody
public Employee addEmployee() {
 Employee employee = new Employee();
 employee.setLastName("chen").setAge(18).setEmail("10000@qq.com").setGender(1);
 employeeService.saveOrUpdate(employee);
 return employee;
}

或者mapper层使用insert方法也会返回主键

@Override
public Employee saveEmp(Employee employee) {
 baseMapper.insert(employee);
 return employee;
}
