Spring Boot Starter Data Rest，@Notnull约束不起作用 [英] Spring boot starter data rest, @Notnull constraint not working

问题描述

我正在尝试将@NotNull约束添加到我的Person对象中，但是我仍然可以@POST用空电子邮件发送新的Person.我在MongoDB上使用Spring Boot Rest.

I am trying to add @NotNull constraint into my Person object but I still can @POST a new Person with a null email. I am using Spring boot rest with MongoDB.

实体类:

import javax.validation.constraints.NotNull;

public class Person {
    @Id 
    private String id;
    private String username;
    private String password;
    @NotNull // <-- Not working
    private String email;
    // getters & setters
}

存储库类:

@RepositoryRestResource(collectionResourceRel = "people", path = "people")
public interface PersonRepository extends MongoRepository<Person, String> {
}

应用程序类:

@SpringBootApplication
public class TalentPoolApplication {
    public static void main(String[] args) {
        SpringApplication.run(TalentPoolApplication.class, args);
    }
}

pom.xml

...
<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.4.0.BUILD-SNAPSHOT</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

当我通过邮递员@POST新对象时，例如:

When I @POST a new object via Postman like:

{
  "username": "deadpool",
  "email": null
}

我仍然使用此有效负载创建STATUS 201:

I still get STATUS 201 created with this payload:

{
    "username": "deadpool",
    "password": null,
    "email": null
     ....
     ....
}

推荐答案

我遇到了同样的问题，但是仅启用验证对我而言不起作用，这确实与JPA和MongoDb一起使用，以节省其他人在此上花费很多时间.这不仅使验证有效，而且还得到了一个很好的宁静的400错误，而不是默认的500错误.

I had the same problem, but just enabling validation didn't work for me, this did work with both JPA and MongoDb to save anyone else spending ages on this. Not only does this get validation working but I get a nice restful 400 error rather than the default 500.

必须将其添加到我的build.gradle依赖项

Had to add this to my build.gradle dependencies

    compile('org.hibernate:hibernate-validator:4.2.0.Final')

和此配置类

@Configuration
public class CustomRepositoryRestConfigurerAdapter extends RepositoryRestConfigurerAdapter {


   @Bean
   public Validator validator() {
       return new LocalValidatorFactoryBean();
   }

   @Override
   public void configureValidatingRepositoryEventListener(ValidatingRepositoryEventListener validatingListener) {
       validatingListener.addValidator("afterCreate", validator());
       validatingListener.addValidator("beforeCreate", validator());
       validatingListener.addValidator("afterSave", validator());
       validatingListener.addValidator("beforeSave", validator());
   }
}
