javax.validation 2.0.1 List<Object> 在 spring 引导中不工作

Question

我是 spring 引导开发的新手。我正在尝试通过从@RequestBody 传递列表来验证 post 请求。下面是控件class

@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class。

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"
}

有人可以帮助如何直接从请求日期验证列表。 https://www.baeldung.com/spring-validate-list-controller 我试过了，但没有帮助。

Answer 1

Errors 参数应跟在经过验证的参数之后：

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经过验证的参数，这是必需的。

Answer 2

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

在绑定用户输入后验证模型是很常见的。 Spring 3 提供对 JSR-303 声明式验证的支持。如果您的类路径中存在 JSR-303 提供程序（例如 Hibernate Validator），则会自动启用此支持。启用后，您可以简单地通过使用 @Valid 注释对 Controller 方法参数进行注释来触发验证：

Answer 3

validation-api是规范，hibernate-validator是实现，简单来说

spring-boot-starter-web会自动导入hibernate-validator，然后hibernate -validator 会自动导入 validation-api.

加上你的jar依赖配置，有两个版本validation-api。一个是由 hibernate-validator 5.3.6（来自 spring-boot-starter-web）导入的 1.1.0，另一个是由您的显式声明导入的 2.0.1。 validation-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。

当您删除 validation-api 2.0.1 时，将使用 1.1.0 版本。但是 javax.validation.constraints.NotEmpty 没有和 validation-api 1.1.0 一起引入，所以你会得到另一个错误。

解决这个问题的几种方法：

删除 validation-api 2.0.1，使用 org.hibernate.validator.constraints.NotEmpty 代替 javax.validation.constraints.NotEmpty。
删除validation-api 2.0.1，升级spring引导版本到2.x，它将使用hibernate-validator6.x和validation-api2.x.
保留您明确的 validation-api 2.0.1 声明。然后添加另一个 hibernate-validator 6.0.14 声明。此案例应该经过全面测试，因为可能存在一些 Spring 支持问题。

Answer 4

我遇到了类似的问题，如果您使用的是 spring 引导版本 (2.3.0) 及更高版本，那么 validation-api 将无法工作。

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

只需要在pom.xml中添加上面的依赖即可。请参阅发行说明：https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.3-Release-Notes#validation-starter-no-longer-included-in-web-starters
