@Valid Bean驗證的球衣

Question

不工作在我的pom.xml文件中我有這些撂荒依賴也會添加

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

和延伸ResourceConfig我CustomApplication類我已經註冊了這2個休耕性能

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

我有一個DTO（POJO）這樣

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RESOUR CE類我試圖驗證此usingg @Valid

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

當我把這些@NotNull驗證請求沒有一個正在

能有人幫我這個

Answer 1

@NotNull 

註釋僅適用於字符串和包裝有效。它不會在int，float和boolean等基元上工作，因爲它們已經有了默認值。

Answer 2

請執行以下操作得到驗證。這個對我有用。

1. 類實現Validator，InitializingBean春季
2. 班新澤西配置實現ContextResolver<ValidationConfig>。

3. 類如果你使用maven可以實現通過ValidationMessages.properties投入資源路徑內化和國產化實施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); 
        } 
       } 
   }
