使用spring-data-mongodb进行审计

Question

我正在尝试使用spring data mongodb启用自动审计字段，如here所解释的那样。下面是我的配置类

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.abc")
@EnableMongoRepositories(basePackages = "com.abc.xyz.repository")
@EnableMongoAuditing
public class ApplicationConfiguration {

    @Bean
    public MongoDbFactory mongoDbFactory() throws Exception {
        ServerAddress serverAddress = new ServerAddress("127.0.0.1", 27017);
        MongoCredential mongoCredential = MongoCredential.createCredential("user", "test", "abc123".toCharArray());
        MongoClient mongoClient = new MongoClient(serverAddress, Arrays.asList(mongoCredential));
        return new SimpleMongoDbFactory(mongoClient, "test");
    }

    @Bean
    public MongoTemplate mongoTemplate() throws Exception {
        return new MongoTemplate(mongoDbFactory());
    }
}

但是当我添加@EnableMongoAuditing时，我在启动服务器时得到以下错误。

Caused by: java.lang.RuntimeException: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mongoAuditingHandler': Cannot create inner bean '(inner bean)#6dca0c34' of type [org.springframework.data.mongodb.config.MongoAuditingRegistrar$MongoMappingContextLookup] while setting constructor argument; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name '(inner bean)#6dca0c34': Unsatisfied dependency expressed through constructor parameter 0: No qualifying bean of type [org.springframework.data.mongodb.core.convert.MappingMongoConverter] found for dependency [org.springframework.data.mongodb.core.convert.MappingMongoConverter]: expected at least 1 bean which qualifies as autowire candidate for this dependency.

Answer 1

您是否可以检查您是否有Spring Data MongoDB dependency 1.9.4.RELEASE或更高版本，因为mongoAuditingHandler需要根据changelog - spring-data-mongodb-changelog在1.9.4.RELEASE或更高版本中提供的MappingMongoConverter，例如：

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-mongodb</artifactId>
    <version>1.9.4.RELEASE</version>
</dependency>

1:确保你有spring-data-mongodb

2:如果你使用的是@CreatedDate或@LastModifiedDate，那么你不需要任何额外的配置。

class ClassName {

    .......

  @CreatedDate
  private DateTime createdDate;

  @LastModifiedDate
  private DateTime @lastModifiedDate;

}

3:如果您使用的是@CreatedBy和@LastModifiedBy，则必须实现AuditorAware<T> SPI接口。

class ClassName {

    .......

    @CreatedBy
    private String createdBy;

    @LastModifiedBy
    private String lastModifiedBy;

}

public class AppAuditor implements AuditorAware<String> {

    @Override
    public String getCurrentAuditor() {

        // get your user name here
        return "xxxx";
    }

}

Spring文档中基于spring Security的AuditorAware实现

class SpringSecurityAuditorAware implements AuditorAware<User> {

  public User getCurrentAuditor() {

    Authentication authentication = SecurityContextHolder.getContext().getAuthentication();

    if (authentication == null || !authentication.isAuthenticated()) {
      return null;
    }

    return ((MyUserDetails) authentication.getPrincipal()).getUser();
  }
}
