当我在邮递员中测试端点时，我的验证不起作用。http://localhost:8080/departments 当我作为 POST 方法输入此 json 时，它仍然可以工作，即使它不应该工作，因为 DepartmentName 字符串上方的 @Size(min = 2) 注释。

{ "departmentName": "a", "departmentAdress":"Mizodora", "departmentCode":"IT-19" }

package com.dailycodebuffer.Springboottutorial.entity;

import jakarta.persistence.Entity;
import jakarta.persistence.GeneratedValue;
import jakarta.persistence.GenerationType;
import jakarta.persistence.Id;
import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;

import javax.validation.constraints.NotBlank;
import javax.validation.constraints.Size;

@Entity
@Data
@NoArgsConstructor
@AllArgsConstructor
@Builder
public class Department {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long departmentId;
    @NotBlank(message = "Please add Department Name")
    @Size(min = 2, message = "Department Name must be at least 2 characters long")
    private String departmentName;
    private String departmentAdress;
    private String departmentCode;
}

package com.dailycodebuffer.Springboottutorial.controller;

import com.dailycodebuffer.Springboottutorial.entity.Department;
import com.dailycodebuffer.Springboottutorial.error.DepartmentNotFoundException;
import com.dailycodebuffer.Springboottutorial.service.DepartmentService;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.*;

import javax.validation.Valid;
import java.util.List;
import java.util.Optional;

@RestController
@Validated
public class DepartmentController {

    @Autowired
    private DepartmentService departmentService;

    private final Logger LOGGER = LoggerFactory.getLogger(DepartmentController.class);

    @PostMapping("/departments")
    public Department saveDepartment(@Valid @RequestBody Department department) {
        LOGGER.info("Inside saveDepartment of DepartmentController");
        return departmentService.saveDepartment(department);
    }

    @GetMapping("/departments")
    public List<Department> fetchDepartmentList() {
        LOGGER.info("Inside fetchDepartment of DepartmentController");
        return departmentService.fetchDepartmentList();
    }

    @GetMapping("/departments/{departmentId}")
    public Optional<Department> fetchDepartmentById(@PathVariable Long departmentId) throws DepartmentNotFoundException {
        return departmentService.fetchDepartmentById(departmentId);
    }

    @DeleteMapping("/departments/{departmentId}")
    public String deleteDepartmentById(@PathVariable Long departmentId) {
        departmentService.deleteDepartmentById(departmentId);
        return "Succes";
    }

    @PutMapping("/departments/{departmentId}")
    public Department updateDepartment(@PathVariable Long departmentId, @RequestBody Department department) {
        return departmentService.updateDepartment(departmentId, department);
    }

    @GetMapping("/departments/name/{departmentName}")
    public Department fetchDepartmentByName(@PathVariable String departmentName) {
        return departmentService.fetchDepartmentByName(departmentName);
    }

}

我尝试使用 json 发送邮递员，但当我输入一个字母时，甚至当我从 json DepartmentName 中删除时，它都不起作用
