【问题描述】：
大家好，当我想将数据插入我的数据库时遇到问题...
insert into New_Single_Order_Response (AveragePrice, BodyLength, CheckSum, ClOrdID, CumQty, Currency, ExecID, ExecTransType, ExecType, Fix_Protocol, LastShares, LeavesQty, MsgSeqNum, MsgType, OrdStatus, OrdType, OrderID, OrderQty, SenderCompId, SendingTime, Side, Symbol, TargetCompID, TransactTime) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)
但我的数据无法插入到我的数据库中……为什么会这样？
首先我使用
设置了我的 persistence.xml<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
version="2.0">
<persistence-unit name="FastMatch" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
<class>com.dxtr.hibernate.newOrderSingleEntity</class>
<properties>
<property name="eclipselink.logging.level" value="INFO"/>
<property name="eclipselink.logging.level.sql" value="FINE"/>
<property name="eclipselink.logging.parameters" value="true"/>
<property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />
<property name="javax.persistence.jdbc.url" value="jdbc:mysql://Url/dxtr_trades" />
<property name="javax.persistence.jdbc.user" value="username" />
<property name="javax.persistence.jdbc.password" value="password" />
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQL57InnoDBDialect" />
<property name="hibernate.show_sql" value="true"/>
<property name="hibernate.hbm2ddl.auto" value="update"/>
<property name="eclipselink.logging.level.connection" value="FINEST"/>
</properties>
</persistence-unit>
</persistence>
这是我的实体

这是我插入数据库的代码
newOrderSingleEntity newordersingleObj = new newOrderSingleEntity();
newordersingleObj.setSymbol(message.getString(Symbol.FIELD));
System.out.print(" symbol "+message.getString(Symbol.FIELD));
newordersingleObj.setMsgType(tipeMessage);
System.out.print(" tipeMessage "+tipeMessage);
newordersingleObj.setBodyLength(216);
System.out.print(" Body Length "+216);
newordersingleObj.setFixProtocol("FIX.4.2");
System.out.print("FixProtocol +FIX.4.2");
newordersingleObj.setTransactTime(message.getString(TransactTime.FIELD));
System.out.print(" time " +message.getString(TransactTime.FIELD));
newordersingleObj.setClOrdID(message.getString(ClOrdID.FIELD));
System.out.print(" ClOrdID "+message.getString(ClOrdID.FIELD));
newordersingleObj.setOrderID(message.getString(OrderID.FIELD));
System.out.print(" OrderID "+message.getString(OrderID.FIELD));
newordersingleObj.setExecID(message.getString(ExecID.FIELD));
System.out.print(" ExecID "+message.getString(ExecID.FIELD));
newordersingleObj.setExecTransType(message.getString(ExecTransType.FIELD));
System.out.print(" ExecTransType "+message.getString(ExecTransType.FIELD));
newordersingleObj.setOrdType(message.getString(OrdType.FIELD));
System.out.print(" OrdType "+message.getString(OrdType.FIELD));
newordersingleObj.setExecType(message.getString(ExecType.FIELD));
System.out.print(" ExecType "+message.getString(ExecType.FIELD));
newordersingleObj.setOrdStatus(message.getString(OrdStatus.FIELD));
System.out.print(" OrdStatus "+message.getString(OrdStatus.FIELD));
newordersingleObj.setSide(message.getInt(Side.FIELD));
System.out.print(" Side "+message.getInt(Side.FIELD));
newordersingleObj.setOrderQty(message.getDouble(OrderQty.FIELD));
System.out.print(" OrderQty "+message.getDouble(OrderQty.FIELD));
newordersingleObj.setLeavesQty(message.getDouble(LeavesQty.FIELD));
System.out.print(" LeavesQty "+message.getDouble(LeavesQty.FIELD));
newordersingleObj.setCumQty(message.getDouble(CumQty.FIELD));
System.out.print(" CumQty "+message.getDouble(CumQty.FIELD));
newordersingleObj.setLastShares(message.getInt(LastShares.FIELD));
System.out.print(" LastQty "+message.getInt(LastShares.FIELD));
} catch (FieldNotFound e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SQLException e) {

}
}
我用过这样的 try catch 但没有错误...我认为我的应用程序也无法运行我的休眠模式
当我记录我想要插入的值时，存在并且该值不存在？？？？那么我的问题到底是什么？以及如何解决我的问题？我想要做的是将该数据插入到 mydatabase mysql5.7
这是我在这里使用的库
在我更改了我的 mysqlconnector 后，我得到了类似的信息
Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.
Mon Apr 13 08:28:46 UTC 2020 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL $.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with exist$ng applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting us$SSL=false, or set useSSL=true and provide truststore for server certificate verification.
究竟是什么问题？
【问题讨论】：
-
您已经发布了除错误消息之外的所有内容。你在
catch块中写过e.printStackTrace()吗？如果没有，请这样做并再次执行您的程序。这样做之后，您可能不需要任何人的帮助。 -
是的，我有 catch } catch (FieldNotFound e) { // TODO 自动生成的 catch 块 e.printStackTrace(); } catch (SQLException e) { // TODO 自动生成的 catch 块 e.printStackTrace();但是错误没有向我显示它就像我的休眠无法连接到我的数据库......为什么这样？

我建议你从一些基础教程开始，比如codejava.net/frameworks/hibernate/…

mysql5.7 有什么例子吗？有 mysql 5.5 的教程
