我想配置MongoDB的審計在我的春天啓動的應用程序，並試圖堅持我的域名類當具有這個錯誤我：從這裏https://docs.spring.io/spring-data/mongodb/docs/current/reference/html/#auditing春季啓動MongoDB的審計錯誤
java.lang.IllegalArgumentException: Couldn't find PersistentEntity for type class com.example.hateoasapi.domain.Post!
文件說，這是所有配置足夠了，但我不知道爲什麼它在我的項目中不起作用。有人能幫助我嗎？
我的MongoDB配置類：
package com.example.hateoasapi.config;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.mongodb.config.AbstractMongoConfiguration;
import org.springframework.data.mongodb.config.EnableMongoAuditing;
import org.springframework.data.mongodb.core.MongoTemplate;
import com.mongodb.MongoClient;
import org.springframework.data.mongodb.repository.config.EnableMongoRepositories;
import java.util.Collection;
import java.util.Collections;
@Configuration
@EnableMongoAuditing
@EnableMongoRepositories(value = "com.example.hateoasapi.repository")
public class MongoConfig extends AbstractMongoConfiguration {
@Value("${spring.data.mongodb.database}")
private String databaseName;
@Value("${spring.data.mongodb.host}")
private String databaseHost;
@Value("${spring.data.mongodb.port}")
private Integer databasePort;
@Override
protected String getDatabaseName() {
return this.databaseName;
}
@Bean
@Override
public MongoClient mongoClient() {
return new MongoClient(databaseHost, databasePort);
}
@Bean
public MongoTemplate mongoTemplate() {
return new MongoTemplate(mongoClient(), databaseName);
}
@Override
protected Collection<String> getMappingBasePackages() {
return Collections.singleton("com.example.hateoasapi.domain");
}
}
AuditorAware實現：
package com.example.hateoasapi.config;
import com.example.hateoasapi.domain.User;
import org.springframework.data.domain.AuditorAware;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.stereotype.Component;
import java.util.Optional;
@Component
public class SecurityAuditor implements AuditorAware<User> {
@Override
public Optional<User> getCurrentAuditor() {
Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
if (authentication == null || !authentication.isAuthenticated()) {
return null;
}
return Optional.of((User) authentication.getPrincipal());
}
}
我的域類：
package com.example.hateoasapi.domain;
import javax.persistence.Id;
import javax.validation.constraints.NotBlank;
import javax.validation.constraints.NotEmpty;
import org.joda.time.DateTime;
import org.springframework.data.annotation.CreatedBy;
import org.springframework.data.annotation.CreatedDate;
import org.springframework.data.annotation.LastModifiedDate;
import org.springframework.data.mongodb.core.mapping.DBRef;
import org.springframework.data.mongodb.core.mapping.Document;
import org.springframework.data.mongodb.core.mapping.Field;
import org.springframework.hateoas.ResourceSupport;
import com.fasterxml.jackson.annotation.JsonCreator;
import lombok.Getter;
import lombok.Setter;
import lombok.ToString;
import static org.springframework.hateoas.mvc.ControllerLinkBuilder.*;
import java.io.Serializable;
import java.util.List;
import com.example.hateoasapi.controller.*;
@Getter
@Setter
@ToString
@Document
public class Post extends ResourceSupport implements Serializable {
@Id
@Field(value = "_id")
private String objectId;
@DBRef
private List<Comment> comments;
@DBRef
private User author;
@NotBlank
private String body;
@NotBlank
private String title;
private String categoryId;
@NotEmpty(message = "Tags cannot be empty")
private List<PostTag> tags;
@CreatedDate
private DateTime createdDate;
@LastModifiedDate
private DateTime lastModifiedDate;
@CreatedBy
private User createdBy;
private Long views;
private List<PostRating> likes;
private List<PostRating> dislikes;
@JsonCreator
public Post() {}
public Post(String title, String body) {
this.body = body;
this.title = title;
}
public Post(User author, String body, String title, String categoryId, List<PostTag> tags) {
this.author = author;
this.body = body;
this.title = title;
this.categoryId = categoryId;
this.tags = tags;
}
public void addLinks() {
this.add(linkTo(methodOn(PostController.class).getAllPosts(null)).withSelfRel());
}
}
