我有一個REST API是這樣的：的REST API類級別的驗證，即使不執行驗證
@POST
@Path("/dopost")
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces("text/plain")
public String doPostExample(@Valid @BeanParam final DemoBean demo) {
return "done";
}
輸入是儲存到這個bean：
@Address
public class DemoBean {
private String address;
private String city;
// Other member variables
// getters and setters
}
正如我想驗證一組字段（與位置有關），我創建了一個類級別的驗證器。
這是我創建的註釋：
@Target({ElementType.METHOD, ElementType.FIELD, ElementType.ANNOTATION_TYPE, ElementType.CONSTRUCTOR, ElementType.PARAMETER, ElementType.TYPE_USE})
@Retention(RUNTIME)
@Constraint(validatedBy = AddressValidator.class)
@Documented
public @interface Address {
String message() default "{com.mycompany.constraints.checkcase}";
Class<?>[] groups() default {};
Class<? extends Payload>[] payload() default {};
}
而且這裏有驗證：
public class AddressValidator implements ConstraintValidator<Address, Address> {
public void initialize(Address constraintAnnotation) {
// initialize the zipcode/city/country correlation service
}
@Override
public boolean isValid(Address address, ConstraintValidatorContext constraintValidatorContext) {
return true; // I put a breakpoint here, but it doesn't stop here and I have the stack trace below
}
}
但是東西一定讓人非常錯誤的，因爲它不工作。我在日誌中得到這個堆棧跟蹤：
