我正在尝试在多模块 Maven 3 项目中使用 Spring Data for MongoDB 设置我的第一个 Java 应用程序。以下是相关版本:
- 爪哇 7
- mongodb-win32-x86_64-2.2.0
- Spring Data 1.1.1.RELEASE
- Spring 3.2.0.RELEASE
我收到以下运行时错误:
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'actorFacade': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private es.mi.casetools.praetor.persistence.springdata.repositories.ActorRepository es.mi.casetools.praetor.facade.impl.DefaultActorFacade.actorRepository; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'actorRepository': FactoryBean threw exception on object creation; nested exception is org.springframework.data.mapping.PropertyReferenceException: No property insert found for type void

在 google 中搜索我发现有同样问题的人,它似乎与自定义存储库有关。
这是我要存储为 mongo 文档的实体。
public class Actor {
public enum ActorStereotype {
SYSTEM,
PERSON
}
private String id;
private String code; // unique
private ActorStereotype stereotype;
private String title; // Short title for the actor
private String description;
private String projectId; // project this actor belongs to
// getters & setters
标准存储库接口。
public interface ActorRepository extends MongoRepository<Actor, String>, ActorRepositoryCustom {
}
自定义界面(我认为错误所在的位置)。
@NoRepositoryBean
public interface ActorRepositoryCustom {
void updateSingleActor(Actor actor);
void insertActor(Actor actor);
}
自定义接口实现。
public class ActorRepositoryCustomImpl implements ActorRepositoryCustom {
@Autowired
private MongoTemplate mongoTemplate;
@Override
public void updateSingleActor(Actor actor) {
if(actor.getId() != null)
throw new MissingIdException();
// TODO change to Spring Converter
DBObject dbo = (DBObject)mongoTemplate.getConverter().convertToMongoType(actor);
mongoTemplate.updateFirst(query(where("_id").is(actor.getId())),
Update.fromDBObject(dbo, new String[]{}),
Actor.class);
}
@Override
public void insertActor(Actor actor) {
if(actor.getId() != null)
throw new IdProvidedException();
mongoTemplate.save(actor);
}
}
最后是应用程序上下文。
<context:annotation-config/>
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:properties/test.properties</value>
</list>
</property>
</bean>
<!-- mongodb configuration -->
<mongo:repositories base-package="es.mi.casetools.praetor.persistence.springdata.repositories"
mongo-template-ref="mongoTemplate" repository-impl-postfix="Impl">
<repository:exclude-filter type="annotation" expression="org.springframework.data.repository.NoRepositoryBean"/>
</mongo:repositories>
<mongo:mongo id="mongotest" host="${mongo.host}" port="${mongo.port}" write-concern="SAFE">
</mongo:mongo>
<mongo:db-factory dbname="${mongo.dbname}" mongo-ref="mongotest"/>
<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
<constructor-arg name="mongoDbFactory" ref="mongoDbFactory"/>
</bean>
<bean id="actorFacade" class="es.mi.casetools.praetor.facade.impl.DefaultActorFacade">
</bean>
</beans>
我还有一个小的 Spring 测试,无法加载上述应用程序上下文,给出了我在顶部附近列出的异常。
我尝试添加以下内容,但我得到了同样的异常。
<bean id="actorRepositoryCustomImpl" class="es.mi.casetools.praetor.persistence.springdata.repositories.ActorRepositoryCustomImpl"></bean>
有人知道错误可能是什么吗?
