我一直在尝试将弹簧验证器添加到spring-data-rest项目中.

我跟着并通过以下链接设置"入门"应用程序:http://spring.io/guides/gs/accessing-data-rest/

...现在我正在尝试通过以下文档添加自定义PeopleValidator:http://docs.spring.io/spring-data/rest/docs/2.1.0.RELEASE/reference/html/validation-chapter html的

我的自定义PeopleValidator看起来像

package hello;

import org.springframework.validation.Errors;
import org.springframework.validation.Validator;

public class PeopleValidator implements Validator {
    @Override
    public boolean supports(Class<?> clazz) {
        return true;
    }

    @Override
    public void validate(Object target, Errors errors) {
        errors.reject("DIE");
    }
}

...而我的Application.java类现在看起来像这样

package hello;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.data.rest.webmvc.config.RepositoryRestMvcConfiguration;

@Configuration
@EnableJpaRepositories
@Import(RepositoryRestMvcConfiguration.class)
@EnableAutoConfiguration
public class Application {

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

    @Bean
    public PeopleValidator beforeCreatePeopleValidator() …

我有一个@RepositoryEventHandler设置,并没有因为一些未知的原因被调用.

@Component
@RepositoryEventHandler(User.class)
public class UserEventHandler {

    @Autowired
    private PasswordCrypto passwordCrypto;

    @HandleBeforeSave
    public void handleUserSave(User user) {
        if (user.getPassword() != null && !"".equals(user.getPassword())) {
            user.setPassword(passwordCrypto.encrypt(user.getPassword()));
        }
    }

    @HandleBeforeCreate
    public void handleUserCreate(User user) {
        user.setPassword(passwordCrypto.encrypt(user.getPassword()));
    }
}

存储库:

public interface UserRepository extends CrudRepository<User, Long> {
    Optional<User> findOneByUsername(String username);
}

而我的主要课程:

@SpringBootApplication
@EntityScan("de.ihrig.feuerwehr.hydranet.model")
@EnableJpaRepositories
@ComponentScan({
    "somepath",
    "somepath including the UserEventHandler"
})
public class ServerApplication {

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

感谢您提前的帮助,我只是找不到错误.
