Java Hibernate 5.2.10 Final和MySQL 5.7中的LocalDate存在问题

我在项目中使用了Java8、Hibernate 5.2.10Final和MySQL 5.7。但是我在使用

java.time.LocalDate

时遇到了一些问题。 有两个实体类：

TradeDay.class：

@Entity
@Table(name = "ENTITY__TRADE_DAY")
public class TradeDay {
    @Id
    @Column(name = "TRADE_DAY_DATE")
    private LocalDate date;

    ........

    @OneToMany(targetEntity = Transaction.class, mappedBy = "tradeDay", cascade = CascadeType.ALL)
    @LazyCollection(LazyCollectionOption.EXTRA)
    private Set<Transaction> transactionSet=new LinkedHashSet<>();

    ........
}

然后我遇到的问题是：

1.当我在HQL中使用

LocalDate

作为键时，SQL中的最终值将是上一个日期。例如：

@Override
public List<Transaction> getTransactionList(LocalDate date) {
    Session session = HibernateSessionManager.getCurrentSession();
    Query<Transaction> query = session.createQuery("from Transaction t where t.date=? order by t.index asc", Transaction.class);
    query.setParameter(0,date);
    return query.list();
}

输出如下：

//Just a count SQL because of @LazyCollection(LazyCollectionOption.EXTRA)
Hibernate: select count(TRANSACTION_INDEX) from ENTITY__TRANSACTION where TRADE_DAY_DATE =?

//count SQL got 4 result
1990-12-20 complete with 4 records.

//Iterate set, real SQL
Hibernate: select ...... from ENTITY__TRANSACTION transactio0_ where transactio0_.TRADE_DAY_DATE=?

//No index output???

//SQL by getTransactionList
Hibernate: select ...... from ENTITY__TRANSACTION transactio0_ where transactio0_.TRANSACTION_DATE=? order by transactio0_.TRANSACTION_INDEX asc

//Got 4 result too
1990-12-20 complete with 4 records.

//Success print the index

如何解决这些问题？感谢您的帮助。

最近，当某人的数据库与另一台服务器上的时区不同时，这引起了很大的噪音。这里有讨论和建议的解决方案，它们告诉您哪些属性要更改为JDBC url和Hibernate配置。您正在使用的MySql驱动程序版本是什么？另外，您是否可以更改您的连接配置，主要是

URL

property？@fujy驱动程序版本是mysql连接器java 6.0.6，

connection.URL

是

jdbc:mysql://192.168.1.122/quant

@coladict感谢您的帮助。实际上，我的客户端和服务器具有相同的时区（亚洲/上海）。我尝试使用属性hibernate.jdbc.time\u zone，但结果没有任何差别。

......//Before, get a TradeDay entity

Set<Transaction> transactionSet=tradeDay.getTransactionSet();
System.out.println(tradeDay.getDate()+" complete with "+transactionSet.size()+" records.");
for(Transaction transaction:transactionSet){
    System.out.println(transaction.getIndex());
}

//Impl of `getTransactionList` is the code above
List<Transaction> transactionList=DAOManager.getTransactionDAO().getTransactionList(tradeDay.getDate());
System.out.println(tradeDay.getDate()+" complete with "+transactionList.size()+" records.");
for(Transaction transaction:transactionList){
    System.out.println(transaction.getIndex());
}

//Just a count SQL because of @LazyCollection(LazyCollectionOption.EXTRA)
Hibernate: select count(TRANSACTION_INDEX) from ENTITY__TRANSACTION where TRADE_DAY_DATE =?

//count SQL got 4 result
1990-12-20 complete with 4 records.

//Iterate set, real SQL
Hibernate: select ...... from ENTITY__TRANSACTION transactio0_ where transactio0_.TRADE_DAY_DATE=?

//No index output???

//SQL by getTransactionList
Hibernate: select ...... from ENTITY__TRANSACTION transactio0_ where transactio0_.TRANSACTION_DATE=? order by transactio0_.TRANSACTION_INDEX asc

//Got 4 result too
1990-12-20 complete with 4 records.

//Success print the index
