我在插入数据库时遇到问题。这是我插入数据库的设置。
首先，我有 getExecutionReport 方法
首先是我导入的内容
import com.dxtr.hibernate.DAOInsert;
import com.dxtr.hibernate.newOrderSingleEntity;
private void getExecutionReport(quickfix.Message message, String tipeMessage) {
// TODO Auto-generated method stub
try {
System.out.print("Message "+ message);
System.out.print("getExecutionReport "+tipeMessage);
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));
System.out.print("sebelum insert ke db");
DAOInsert.newOrderSingleInsert(newordersingleObj);
} catch (FieldNotFound e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
这段代码没问题。但是当我想插入到数据库时，我的数据无法插入。

这是我的用于插入数据库的类
package com.dxtr.hibernate;
import java.util.ArrayList;
import java.util.List;
import org.apache.log4j.Logger;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import quickfix.StringField;
public class DAOInsert {
private DAOInsert dAOInsert;
static Session sessionObj;
static SessionFactory sessionFactoryObj;
public final static Logger logger = Logger.getLogger(DAOInsert.class);
// This Method Is Used To Create The Hibernate's SessionFactory Object
public static SessionFactory buildSessionFactory() {
// Creating Configuration Instance & Passing Hibernate Configuration File
Configuration configObj = new Configuration();
configObj.configure("hibernate.cfg.xml");
// Since Hibernate Version 4.x, ServiceRegistry Is Being Used
ServiceRegistry serviceRegistryObj = new StandardServiceRegistryBuilder().applySettings(configObj.getProperties()).build();
// Creating Hibernate SessionFactory Instance
sessionFactoryObj = configObj.buildSessionFactory(serviceRegistryObj);
return sessionFactoryObj;
}
public static void newOrderSingleInsert(newOrderSingleEntity newordersingleObj){
int count = 0;
try {
System.out.print("sudah di DAOInsert");
// Getting Session Object From SessionFactory
sessionObj = buildSessionFactory().openSession();
// Getting Transaction Object From Session Object
sessionObj.beginTransaction();
sessionObj.persist(newordersingleObj);
System.out.print(sessionObj.contains(newordersingleObj));
// Creating Transaction Entities
// newordersingleObj = new NewOrderSingle();
//newordersingleObj.setFixProtocol("FIX.4.2");
//newordersingleObj.setBodyLength(250);
//sessionObj.save(newordersingleObj);
//Committing The Transactions To The Database
sessionObj.getTransaction().commit();
//logger.info("\nSuccessfully Created '" + count + "' Records In The Database!\n");
} catch(Exception e) {
if(null != sessionObj.getTransaction()) {
logger.info("\n.......Transaction Is Being Rolled Back.......\n");
sessionObj.getTransaction().rollback();
}
e.printStackTrace();
} finally {
if(sessionObj != null) {
sessionObj.close();
}
}
}
}
我还设置了 persistence.xml
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1"
xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">

<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
<property name="eclipselink.logging.level.connection" value="FINEST"/>
</properties>
</persistence-unit>
</persistence>
而且我还有 hibernate.cfg.xml
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<property name="show_sql">true</property>
<property name="hbm2ddl.auto">update</property>
<mapping class="com.dxtr.hibernate.newOrderSingleEntity"></mapping>
</session-factory>
</hibernate-configuration>
但是当我想插入到数据库中时，该数据无法插入..但我不知道错误在哪里...我已经使用
捕获了错误catch(Exception e) {
if(null != sessionObj.getTransaction()) {
logger.info("\n.......Transaction Is Being Rolled Back.......\n");
sessionObj.getTransaction().rollback();
}
e.printStackTrace();
} finally {
if(sessionObj != null) {
sessionObj.close();
}
但是我的控制台打印中没有错误...那么我的代码问题出在哪里？ 有关信息我使用 mysql5.7 版本并使用 aws
最诚挚的问候， 福阿德
最佳答案
我建议您启用 MySQL 日志，然后按照 https://dev.mysql.com/doc/refman/5.7/en/server-logs.html 中的说明进行操作。并且一定要刷新日志。日志应该位于/bar/log/MySQL
关于java - 无法将数据插入到数据库 mysql 中的我的表中，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/61079682/
