【问题描述】：

public void nullSafeSet(PreparedStatement statement, Object value, int index, SharedSessionContractImplementor session) throws HibernateException, SQLException 
    if (value == null) 
        statement.setNull(index, SQL_TYPE, DB_OBJECT_TYPE);
     else 
        final AuditType user = (AuditType) value;
        final Object[] values = new Object[]  convertDate(user.getPreparedOn()),
                convertDate(user.getCheckedOnDate()), convertDate(user.getCancelReverseOn()),
                convertDate(user.getAuthorizedOn()), user.getPreparedBy(), user.getCancelReverseBy(),
                user.getAuthorizedBy(), user.getCheckedBy(), user.getCancellationReason() ;
        final Connection connection = statement.getConnection();
        OracleConnection oracleConection = null;
        try (Connection hikariCon = statement.getConnection()) 
            if (hikariCon.isWrapperFor(OracleConnection.class)) 
                oracleConection = hikariCon.unwrap(OracleConnection.class);

            
            @SuppressWarnings("deprecation")
            final STRUCT struct = new STRUCT(StructDescriptor.createDescriptor(DB_OBJECT_TYPE, oracleConection),
                    oracleConection, values);
            statement.setObject(index, struct, SQL_TYPE);

【问题讨论】：

这不是问题。

你的代码是什么？您是否在访问其数据之前关闭语句？

我在使用这个类

使用edit链接将您尝试在评论中添加的任何代码包含在问题中

@Mushtaqhussain 欢迎来到 SO！请添加您采取的步骤或导致此异常的代码，因为这会有所帮助。没有？

【参考方案1】：

您正在实现您的自定义类型处理程序。对于没有经历过这种情况的人来说，从您的问题来看，这一点并不明显。

从所有代码中删除那些 try-with-resources 语句，而不仅仅是在这个给定的示例中。我的意思是这部分：

    try (Connection hikariCon = statement.getConnection()) 
        if (hikariCon.isWrapperFor(OracleConnection.class)) 
            oracleConection = hikariCon.unwrap(OracleConnection.class);

        
        @SuppressWarnings("deprecation")
        final STRUCT struct = new STRUCT(StructDescriptor.createDescriptor(DB_OBJECT_TYPE, oracleConection),
                oracleConection, values);
        statement.setObject(index, struct, SQL_TYPE);
    

必须变成：

    Connection hikariCon = statement.getConnection();
    if (hikariCon.isWrapperFor(OracleConnection.class)) 
        oracleConection = hikariCon.unwrap(OracleConnection.class);
    
    final STRUCT struct = new STRUCT(StructDescriptor.createDescriptor(DB_OBJECT_TYPE, oracleConection),
            oracleConection, values);
    statement.setObject(index, struct, SQL_TYPE);

try-with-resources 部分会在您的连接上自动调用 close()，这会导致您到达此部分时出错。

【讨论】：

感谢这解决了我的问题。

【参考方案2】：

正如我们在这里看到的那样，当您尝试 setString 时，您已经关闭了与 DB 的连接。 方式是可能的

当您不创建任何与 DB 的连接时 当您创建但未打开任何与 DB 的连接时 当您在尝试将 DML 转换为 DB 之前创建甚至打开但关闭连接时。

【讨论】：

它不在我手中我在某些实体中有 oracle 类型对象，当我尝试通过实现 org.hibernate.usertype.UserType 来保存该实体时

我已经编辑了问题你可以看到方法 public void nullSafeSet(PreparedStatement statement, Object value, int index, SharedSessionContractImplementor session)

您可以在statement.setNull(index, SQL_TYPE, DB_OBJECT_TYPE); 之前设置一些日志或System.out.println("is null "); 似乎，该值为空，但连接仍处于关闭状态，因为您只有在以下几行之后才会打开它。在if (value == null) 行上设置断点并在调试模式下启动程序很简单，您将在其中看到异常发生的位置

此方法中没有引发异常，设置此类型对象后，当它要设置其他字段时，它会给出此错误

在 stackTrace 中我没有看到您的程序的任何行。但最重要的是，关于一些图书馆。看看here 可能会解决你的问题。无论如何。如果您向我们展示生成异常的代码会很好
