javax.validation2.0.1列表不工作在Spring启动

Question

我是Spring启动开发的新手。我正在尝试通过从@Request estbody传递List来验证帖子请求。下面是控制类

@CrossOrigin
@RestController
@RequestMapping("/webapi/device")
@Validated
public class DeviceController extends AuthControllerImpl{

    @Autowired
    private DeviceServices deviceServices;


    //Test Postman request 01
    @PostMapping(path = "/udateDevices", consumes = MediaType.APPLICATION_JSON,  produces = MediaType.APPLICATION_JSON)
    public ResponseEntity<Object> updateDeviceToDB( @RequestBody List<@Valid Device> device, @RequestParam("token") String token, Errors errors)    {
        if (errors.hasErrors()) {
            return new ResponseEntity<Object>(new ErrorResponse(errors), HttpStatus.BAD_REQUEST);
        }

        if(isValidToken(token) != null){
            DeviceControllerResponse response = deviceServices.updateDeviceToDB(device);
            if (!response.isSuccess()) {
                return new ResponseEntity<Object>(response, HttpStatus.BAD_REQUEST);
            }
            return ResponseEntity.ok(response); 
        }else {
            return new ResponseEntity<Object>("Token has been expired/not valid.", HttpStatus.UNAUTHORIZED);
        }

    }
}

下面是我的实体类。

import javax.validation.constraints.NotEmpty;

import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;

@Document(collection = "rpDevices")
public class Device {

    @Id
    private String id;

    @NotEmpty(message = "device udid should not be empty")
    private String udid;

    @NotEmpty(message = "deviceModel should not be empty")
    private String deviceModel;

    @NotEmpty(message = "device location should not be empty")
    private String location;

    @NotEmpty(message = "device port should not be empty")
    private String port;

    private String url;

    private String lastUpdate;
    private String imsi;
    private String msisdn;

    private String aliasName;

    public Device() {
        super();
    }

    public Device(String id, String udid, String deviceModel, String location, String port, String url,
            String lastUpdate, String imsi, String msisdn, String aliasName) { 
        this.id = id;
        this.udid = udid;
        this.deviceModel = deviceModel;
        this.location = location;
        this.port = port;
        this.url = url;
        this.lastUpdate = lastUpdate;
        this.imsi = imsi;
        this.msisdn = msisdn;
        this.aliasName = aliasName;
    }
    //Getter and setters 

}

它从不验证实体并给出以下错误。

    {
    "timestamp": 1591497348682,
    "status": 500,
    "error": "Internal Server Error",
    "exception": "javax.validation.UnexpectedTypeException",
    "message": "HV000030: No validator could be found for constraint 'javax.validation.constraints.NotEmpty' validating type 'java.lang.String'. Check configuration for 'updateDeviceToDB.device[0].port'",
    "path": "/xxxx/webapi/device/udateDevices"
}

有人可以帮助如何验证列表直接从请求boday。https://www.baeldung.com/spring-validate-list-controller我尝试了这个，但没有帮助。

Answer 1

错误参数应遵循已验证的参数：

public ResponseEntity<Object> updateDeviceToDB( @RequestBody List<@Valid Device> device, Errors errors, @RequestParam("token") String token) 

为了在单个方法中支持多个已验证的参数，这是必需的。

Answer 2

我也有类似的问题，如果您使用的是Spring Boot版本（2.3.0）及更高版本，那么valization-api将不起作用。

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-validation</artifactId>
</dependency>

只需在pom中添加上述依赖项。xml。请参阅发行说明：https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.3-Release-Notes#validation-web启动器中不再包含启动器

Answer 3

简单地说，验证api是规范，hibernate validator是实现。

spring boot starter web将自动导入hibernate validator，然后hibernate validator将自动导入验证api。

在jar依赖项配置中，有两个版本的验证api。一个是由hibernate validator 5.3.6导入的（从spring boot starter web），另一个是由显式声明导入的<代码>验证api 2.0.1将与hibernate validator 5.3.6一起使用，这是不兼容的。导致找不到验证器错误。

删除验证api 2.0.1时，将使用1.1.0版本。但是javax。验证。约束条件。注意：验证api 1.1.0未引入空，因此您将收到另一个错误。

解决这个问题的几种方法：

1. 删除验证api 2.0.1，使用组织。冬眠验证器。约束条件。NotEmpty代替javax。验证。约束条件。注意空
2. 删除验证api 2.0.1，将spring boot版本升级到2。x、 它将使用hibernate validator 6。x和验证api 2。x、
3. 保留您的显式验证api 2.0.1声明。然后添加另一个hibernate validator 6.0.14声明。这种情况应该进行全面测试，因为可能存在一些Spring支撑问题
