Question

我正在尝试使用hibernate将数据保存到嵌入式Derby DB。但数据根本没有持续存在。

hibernate配置

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD//EN"
    "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
   <session-factory>
       <property name="hibernate.connection.url">
        jdbc:derby:wso2FlightRecorder
       </property>
       <property name="hibernate.connection.driver_class">
        org.apache.derby.jdbc.EmbeddedDriver
       </property>
       <property name="hibernate.dialect">
        org.hibernate.dialect.DerbyTenSevenDialect
       </property>
       <property name="connection.username"/>
       <property name="connection.password"/>
       <!-- DB schema will be updated if needed -->
       <property name="hibernate.hbm2ddl.auto">create</property>
       <mapping class="org.wso2.esbMonitor.network.PassThruHTTPBean">
       </mapping>
    </session-factory>
</hibernate-configuration>

这是DAO课程

package org.wso2.esbMonitor.network;

import javax.annotation.Generated;
import javax.persistence.*;
import java.util.Date;

@Entity
@Table(name = "HTTP_LOG")
public class PassThruHTTPBean {

    @Id
    @GeneratedValue
    @Column(name = "id")
    private int id;

   @Column(name = "activeThreadCount")
   private int activeThreadCount;

   @Column(name = "avgSizeRecieved")
   private double avgSizeRecieved;

   @Column(name ="avgSizeSent")
   private double avgSizeSent;

   @Column(name ="faultsRecieving")
   private long faultsRecieving;

   @Column(name ="faultSending")
   private long faultSending;

   @Column(name ="messagesRecieved")
   private long messagesRecieved;

   @Column(name ="messageSent")
   private long messageSent;

   @Column(name ="queueSize")
   private int queueSize;

   @Column(name = "time")
   private Date date;
}

这是用于提交DB

的方法

public synchronized static void addNetworkTrafficDetailsToDB(){

        try {
            if (scheduledList.size() > 0){
                logger.info("Started persisting");
                Session session = HibernateSessionCreator.getSession();

                for(PassThruHTTPBean passThruHTTPBean : scheduledList){
                    Transaction tx;
                    tx = session.beginTransaction();
                    session.save(passThruHTTPBean);
                    tx.commit();
                }
                session.flush();
                session.close();
                scheduledList.clear();
            }

请帮我解决问题:)提前谢谢
