java - 自定义存储库基类 + QueryDslPredicateExecutor

Question

我发现 QueryDslPredicateExecutor 对于减少样板文件非常有用，但它似乎给工作带来了麻烦。我现在尝试使用自定义基类存储库扩展 JpaRepository，但在启动时，Spring 无法正确实例化存储库。

//Custom base class
@NoRepositoryBean
public interface IdAwareRepository<A, ID extends Serializable> extends JpaRepository<A, ID> {
    // ID getId(A a);
}

// Base class implementation
public class IdAwareRepositoryImpl<A, ID extends Serializable>
    extends SimpleJpaRepository<A, ID> implements IdAwareRepository<A, ID>  {
    public IdAwareRepositoryImpl(JpaEntityInformation<A, ?> entityInformation, EntityManager entityManager) {
        super(entityInformation, entityManager);
    }
}

// Individual repo
@Repository
public interface MyPojoRepository extends JpaRepository<MyPojo, Integer>, QueryDslPredicateExecutor<MyPojo> {
}

// Spring boot main application class
@EnableJpaRepositories(repositoryBaseClass = IdAwareRepositoryImpl.class)
@EntityScan(basePackageClasses = {Application.class,   Jsr310JpaConverters.class})
@EnableAutoConfiguration(exclude = {
      org.springframework.boot.autoconfigure.security.SecurityAutoConfiguration.class,
      org.springframework.boot.actuate.autoconfigure.ManagementWebSecurityAutoConfiguration.class})
@SpringBootApplication
public class Application {}

我已经尝试过这个主题的几种变体，但没有成功地连接起来。我在 Spring 的问题跟踪器 https://jira.spring.io/browse/DATAJPA-674 上遇到了类似的问题，但没有对修复进行解释，只是代码被重构以使其更易于使用。

我收到以下错误:

Caused by: org.springframework.data.mapping.PropertyReferenceException: No property findAll found for type MyPojo! at org.springframework.data.mapping.PropertyPath.(PropertyPath.java:77) at org.springframework.data.mapping.PropertyPath.create(PropertyPath.java:329) at org.springframework.data.mapping.PropertyPath.create(PropertyPath.java:309) at org.springframework.data.mapping.PropertyPath.from(PropertyPath.java:272) at org.springframework.data.mapping.PropertyPath.from(PropertyPath.java:243) at org.springframework.data.repository.query.parser.Part.(Part.java:76) at org.springframework.data.repository.query.parser.PartTree$OrPart.(PartTree.java:235) at org.springframework.data.repository.query.parser.PartTree$Predicate.buildTree(PartTree.java:373) at org.springframework.data.repository.query.parser.PartTree$Predicate.(PartTree.java:353) at org.springframework.data.repository.query.parser.PartTree.(PartTree.java:84) at org.springframework.data.jpa.repository.query.PartTreeJpaQuery.(PartTreeJpaQuery.java:62) at org.springframework.data.jpa.repository.query.JpaQueryLookupStrategy$CreateQueryLookupStrategy.resolveQuery(JpaQueryLookupStrategy.java:100) at org.springframework.data.jpa.repository.query.JpaQueryLookupStrategy$CreateIfNotFoundQueryLookupStrategy.resolveQuery(JpaQueryLookupStrategy.java:211) at org.springframework.data.jpa.repository.query.JpaQueryLookupStrategy$AbstractQueryLookupStrategy.resolveQuery(JpaQueryLookupStrategy.java:74) at org.springframework.data.repository.core.support.RepositoryFactorySupport$QueryExecutorMethodInterceptor.(RepositoryFactorySupport.java:416) at org.springframework.data.repository.core.support.RepositoryFactorySupport.getRepository(RepositoryFactorySupport.java:206) at org.springframework.data.repository.core.support.RepositoryFactoryBeanSupport.initAndReturn(RepositoryFactoryBeanSupport.java:251) at org.springframework.data.repository.core.support.RepositoryFactoryBeanSupport.afterPropertiesSet(RepositoryFactoryBeanSupport.java:237) at org.springframework.data.jpa.repository.support.JpaRepositoryFactoryBean.afterPropertiesSet(JpaRepositoryFactoryBean.java:92) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods(AbstractAutowireCapableBeanFactory.java:1637) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1574)

对我来说，Spring 无法将自定义基类和 QueryDslPredicateExecutor 扩展连接到 JpaRepository

我通过让我的基础存储库扩展 QueryDslMongoRepository 解决了类似的问题。
您也许能够扩展类似的类。
