小编cir*_*rvo的帖子

我正在使用Spring Boot 1.3.0.M4和MySQL数据库.

我在使用修改查询时遇到问题,EntityManager在执行查询后包含过时的实体.

原始JPA存储库:

public interface EmailRepository extends JpaRepository<Email, Long> {

    @Transactional
    @Modifying
    @Query("update Email e set e.active = false where e.active = true and e.expire <= NOW()")
    Integer deactivateByExpired();

}

假设我们在DB中有Email [id = 1,active = true,expire = 2015/01/01].

执行后:

emailRepository.save(email);
emailRepository.deactivateByExpired();
System.out.println(emailRepository.findOne(1L).isActive()); // prints true!! it should print false

解决问题的第一种方法:添加clearAutomatically = true

public interface EmailRepository extends JpaRepository<Email, Long> {

    @Transactional
    @Modifying(clearAutomatically = true)
    @Query("update Email e set e.active = false where e.active = true and …

我希望我的可审计(@CreatedDate和@LastModifiedDate)MongoDB文档可以使用ZonedDateTime字段.

显然,Spring Data不支持这种类型(请看一下org.springframework.data.auditing.AnnotationAuditingMetadata).

框架版本:Spring Boot 2.0.0和Spring Data MongoDB 2.0.0

Spring Data审核错误:

java.lang.IllegalArgumentException: Invalid date type for member <MEMBER NAME>!
Supported types are [org.joda.time.DateTime, org.joda.time.LocalDateTime, java.util.Date, java.lang.Long, long].

Mongo配置:

@Configuration
@EnableMongoAuditing
public class MongoConfiguration {

}

可审计实体:

public abstract class BaseDocument {

    @CreatedDate
    private ZonedDateTime createdDate;

    @LastModifiedDate
    private ZonedDateTime lastModifiedDate;

}

我试过的事情

我也试过为ZonedDateTime它创建一个自定义转换器,但Spring Data没有考虑它.该类DateConvertingAuditableBeanWrapper有一个ConversionService在构造函数方法中配置的JodaTimeConverters,Jsr310Converters和ThreeTenBackPortConverters.

定制转换器:

@Component
public class …

我将Spring Boot与PostgreSQL JDBC 42.2.13和Hibernate 5.3.18.Final一起使用，似乎在IS NULL向 UUID 集合添加检查时，Hibernate/PostgreSQL 无法确定集合的数据类型。

实体

class Element {
    @Column
    private UUID uuid;
}

存储库

@Query("SELECT e FROM Element e WHERE (:uuids) IS NULL OR e.uuid IN (:uuids)")
    List<Element> findByUuidIn(@Param("uuids") Collection<UUID> uuids);

查询执行

elementRepository.findByUuidIn(List.of(UUID.randomUUID())); // works fine!
elementRepository.findByUuidIn(null); // -> Throws exception

来自跟踪日志记录的参数绑定

org.hibernate.type.descriptor.sql.BasicBinder - binding parameter [1] as [OTHER] - [null]
org.hibernate.type.descriptor.sql.BasicBinder - binding parameter [2] as [OTHER] - [null]

例外
