Spring-Data-Rest验证器

Question

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() {
        return new PeopleValidator();
    }
}

我希望POST到http://localhost:8080/peopleURL会导致某种错误,因为PeopleValidator拒绝了所有内容.但是,不会抛出任何错误,并且永远不会调用验证程序.

我还尝试过手动设置验证器,如spring-data-rest文档的5.1节所示.

我错过了什么？

Answer 1

因此,看起来前/后"保存"事件仅在PUT和PATCH上触发.POST时,"创建"事件之前/之后触发.

我使用configureValidatingRepositoryEventListener覆盖再次尝试手动方式,它工作.我不确定我在工作中做的与在家里做的不同.我明天要看.

我肯定会喜欢听到其他人是否有关于为什么它不起作用的建议.

对于记录,这是新的Application.java类的样子.

package hello;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
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.core.event.ValidatingRepositoryEventListener;
import org.springframework.data.rest.webmvc.config.RepositoryRestMvcConfiguration;

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

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

    @Override
    protected void configureValidatingRepositoryEventListener(ValidatingRepositoryEventListener validatingListener) {
        validatingListener.addValidator("beforeCreate", new PeopleValidator());
    }
}
