Question

将spring-data从1.8升级到1.9后，我收到以下错误：

Caused by: java.lang.IllegalStateException: No suitable constructor found on interface com.acme.util.RepositoryEx to match the given arguments: [Ljava.lang.Object;@4ef820c3

我有一个简单的RepositoryEx类，如：

public interface RepositoryEx<T, ID extends Serializable> extends JpaRepository<T, ID>,
        JpaSpecificationExecutor<T> {

    List<T> findAll(Specification<T> spec, Sort sort, long offset, long count);


}

我的其他存储库接口都是继承的，我还需要添加其他东西吗？

谢谢，杰森

我刚遇到这个问题。我的基本存储库实现类扩展了SimpleJpaRepository，并且只有一个带有参数Class<T> domainClass, EntityManager em的构造函数。添加以下构造函数为我解决了这个问题：

public MyBaseRepositoryImpl(JpaEntityInformation<T, ?> entityInformation, EntityManager entityManager) {
  super(entityInformation, entityManager);
}

升级到spring-data 1.9
