Spring 3 - 基于注解的 Bean 验证 [英] Spring 3 - Annotation based Bean Validation

问题描述

我正在构建一个 REST API.它由一个资源(@Controller)组成，即使其中一个必填字段不存在，它也会返回响应 204.

I am building a REST API. Its made up of a Resource ( @Controller ) which returns a response 204 even when one of the mandatory field is not present.

我使用的是 Spring 3.1，validation-api (1.1.0.Final) &休眠验证器(4.3.0).不确定 Hibernate-validator 是否在这里起作用.

I am using Spring 3.1, validation-api (1.1.0.Final) & Hibernate-validator(4.3.0). Not sure if Hibernate-validator plays any role here.

 <dependency>
            <groupId>javax.validation</groupId>
            <artifactId>validation-api</artifactId>
            <version>1.1.0.Final</version>
        </dependency>
        <dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-validator</artifactId>
            <version>4.3.0.Final</version>
            <exclusions>
                <exclusion>
                    <groupId>javax.validation</groupId>
                    <artifactId>validation-api</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

我有一个弹簧控制器@Controller 和一个带有@Component 的 Bean

I have a spring controller @Controller and a Bean with @Component

  @POST
        @Consumes(value = {MediaType.APPLICATION_JSON})
        @Produces(value = {MediaType.APPLICATION_JSON})
        @RequestMapping(method = RequestMethod.POST)
        public Response addUserData(@Valid @RequestBody UserData userDataRequest) throws ResourceException {
    ...
    }

我的 UserData bean 有

My UserData bean has

  @Component 
    public class UserData {

        @NotNull(message = "user ID should not be null")
        @Min(value = 1, message = "user ID should not be empty")
        @Max(value = 20, message = "user ID should have length of more than 20")
        @Pattern(regexp="[A-Z][a-z]+", message = "Only Alphanumeric characters allowed")
        private String userId;

    }

我的验证没有得到执行.当我不传递userId"时，不会抛出任何错误.我在这里错过了什么?

My validations are not getting executed. When I dont pass "userId", there is no error thrown. What am I missing here ?

推荐答案

我最终使用 Jersey Bean Validation 而不是 Spring.这是因为我的其余代码无论如何都在使用 Jersey.为了完成这项工作，我刚刚导入了 Jersey Bean Validation jar 并对 web.xml 添加了一个小改动.验证现在正在运行.

I ultimately ended up using Jersey Bean Validation, instead of Spring. This is because rest of my code is using Jersey anyways. To make this work I just imported Jersey Bean Validation jar and added a small change to web.xml. Validations are now working.

谢谢@Manual Jordan.我会赞成你的回答，因为它给了我正确的线索.

Thank you @Manual Jordan. I will upvote your answer, since it gave me the right clues.

<!--  jersey beanValidation  -->
       <init-param>
           <param-name>jersey.config.beanValidation.enableOutputValidationErrorEntity.server</param-name>
           <param-value>true</param-value>
       </init-param>
