@Valid Bean 验证在球衣中不起作用

Question

在我的 pom.xml 文件中，我添加了这些休闲依赖项

 <dependency>
     <groupId>org.glassfish.jersey.ext</groupId>
     <artifactId>jersey-bean-validation</artifactId>
     <version>2.25.1</version>
  </dependency>

并且在扩展 ResourceConfig 的我的 CustomApplication class 中，我已经注册了这两个休闲属性

property(ServerProperties.BV_SEND_ERROR_IN_RESPONSE, true); 
property(ServerProperties.BV_DISABLE_VALIDATE_ON_EXECUTABLE_OVERRIDE_CHECK, true);

我有一个这样的 DTO (POJO)

import java.util.ArrayList;
import javax.validation.constraints.NotNull;
import org.hibernate.validator.constraints.NotBlank;

public class PlotDTO {

private String guid;
@NotNull
private String plot_name;
@NotNull
private String farmer_id;
@NotNull
private float distance_from_warehouse;
@NotNull
private int area;
@NotNull
private float sand;
.............
.............
}

在我的资源 class 中，我正在尝试使用 @Valid

来验证这一点

@Path("addplot")
@POST
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public Response addPlot(@Valid PlotDTO plot) 
{
 ..............
 ..............
}

当我发送请求时 none 这些 @NotNull 验证正在工作

谁能帮我解决这个问题

Answer 1

请执行以下操作以进行验证。它对我有用。

Class 为 Spring

Validator

InitializingBean

Class 为 Jersey 配置实施 ContextResolver<ValidationConfig>。

Class 实施 ExceptionMaper<ConstraintViolationException>

@Component
public class BeanValidator implements Validator,InitializingBean {
    private Validator validator;

    public void afterPropertiesSet() throws Exception {
        ValidatorFactory validatorFactory = Validation.buildDefaultValidatorFactory();
        validator = validatorFactory.usingContext().getValidator();
    }

    public boolean supports(Class clazz) {
        return true;
    }

    public void validate(Object target, Errors errors) {
        Set<ConstraintViolation<Object>> constraintViolations = validator.validate(target);
        for (ConstraintViolation<Object> constraintViolation : constraintViolations) {
            String propertyPath = constraintViolation.getPropertyPath().toString();
            String message = constraintViolation.getMessage();
            errors.rejectValue(propertyPath, "", message);
        }
    }

    @Override
    public ExecutableValidator forExecutables() {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public BeanDescriptor getConstraintsForClass(Class<?> arg0) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public <T> T unwrap(Class<T> arg0) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public <T> Set<ConstraintViolation<T>> validate(T arg0, Class<?>... arg1) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public <T> Set<ConstraintViolation<T>> validateProperty(T arg0, String arg1, Class<?>... arg2) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public <T> Set<ConstraintViolation<T>> validateValue(Class<T> arg0, String arg1, Object arg2, Class<?>... arg3) {
        // TODO Auto-generated method stub
        return null;
    }
}

2. Jersey configuration Classes.
@Provider
public class ValidationConfigurationContextResolver implements ContextResolver<ValidationConfig> {
    @Context
    private ResourceContext resourceContext;    

    /**Get a context*/
    @Override
    public ValidationConfig getContext(Class<?> type) {
        final ValidationConfig config = new ValidationConfig();
        config.constraintValidatorFactory(resourceContext.getResource(InjectingConstraintValidatorFactory.class));
        config.parameterNameProvider(new CustomParameterNameProvider());
        return config;
    }

    private class CustomParameterNameProvider implements ParameterNameProvider {
        private final ParameterNameProvider nameProvider;
        public CustomParameterNameProvider() {
            nameProvider = Validation.byDefaultProvider().configure().getDefaultParameterNameProvider();
        }

        @Override
        public List<String> getParameterNames(final Constructor<?> constructor) {
            return nameProvider.getParameterNames(constructor);
        }

        @Override
        public List<String> getParameterNames(final Method method) {
            return nameProvider.getParameterNames(method);
        }
    }
}

如果您使用 Maven，您可以通过使用 ValidationMessages.properties 放入资源路径来实现内部化和本地化。请参考下面link Github- bean-validation-webapp

Answer 2

@NotNull

注释仅对 Strings 和 Wrappers 有效。它不适用于 int、float 和 boolean 等基元，因为它们已经具有默认值。

@Valid Bean 验证在球衣中不起作用

@Valid Bean validation not working in jersey
