對于日志和事件的記錄在每個項目中都會用到，如果在每個manager層中觸發(fā)時間記錄的話，會比較難以擴展和維護，所以可配置的日志和事件記錄在項目中會用到！

首先在spring的配置文件中加入hibernate攔截器

      <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="entityInterceptor"> <ref bean="myInterceptor"/> </property> </bean> <bean id="myInterceptor" class="com.creawor.cbsms.util.MyInterceptor" />
    

<wbr>MyInterceptor攔截器為：</wbr>

      package com.creawor.cbsms.util; import java.io.Serializable; import java.lang.reflect.InvocationTargetExceptio<wbr>n; import java.lang.reflect.Method; import java.util.Iterator; import javacommon.util.ApplicationContextHolder<wbr>; import org.hibernate.CallbackException; import org.hibernate.EntityMode; import org.hibernate.Interceptor; import org.hibernate.Transaction; import org.hibernate.type.Type; import com.creawor.cbsms.event.EventRecord; import com.creawor.cbsms.model.CbsChannel; import com.creawor.cbsms.model.CbsMessage; public class MyInterceptor implements Interceptor{ //刪除時記錄時間 public void onDelete(Object obj, Serializable arg1, Object[] arg2, String[] arg3, Type[] arg4) throws CallbackException { // TODO Auto-generated method stub String[] entitys = EventRecord.getDeleteEntitysFireEven<wbr>t(); for (String entityName : entitys) { if (entityName.equals(obj.getClass().getSimpleName())) { getEventRecordMethod(entityName, obj,EventRecord.getDeleteInfo()); } } } //修改時記錄事件 public boolean onFlushDirty(Object obj, Serializable id, Object[] currentState, Object[] previousState , String[] propertyNames, Type[] types){ String[] entitys = EventRecord.getUpdateEntitysFireEven<wbr>t(); for (String entityName : entitys) { if (entityName.equals(obj.getClass().getSimpleName())) { getEventRecordMethod(entityName, obj, EventRecord.getUpdateInfo()); } } return false; } public String onPrepareStatement(String arg0) { // TODO Auto-generated method stub return arg0; } //保存時記錄事件 public boolean onSave(Object obj, Serializable arg1, Object[] arg2, String[] arg3, Type[] arg4) throws CallbackException { // TODO Auto-generated method stub String[] entitys = EventRecord.getSaveEntitysFireEvent(); for (String entityName : entitys) { if (entityName.equals(obj.getClass().getSimpleName())) { getEventRecordMethod(entityName, obj,EventRecord.getSaveInfo()); } } return false; } //根據(jù)反射機制執(zhí)行事件記錄類中相應(yīng)的函數(shù) public void getEventRecordMethod(String entityName,Object obj,String info){ try { Class[] parameterTypes = {String.class,Class.forName(EventRecord.getPrefixPackageName()+entityName)}; Method method = EventRecord.class.getMethod(EventRecord.getPrefixMethodName()+entityName, parameterTypes); Object[] objs = {info, Class.forName(EventRecord.getPrefixPackageName()+entityName).cast(obj)}; method.invoke((EventRecord)ApplicationContextHolder<wbr>.getBean("eventRecord"),objs); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } }</wbr></wbr></wbr></wbr></wbr>
    

<wbr>事件記錄類：</wbr>

      package com.creawor.cbsms.event; import java.sql.Timestamp; import javacommon.util.ApplicationContextHolder<wbr>; import com.creawor.cbsms.dao.CbsEventDao; import com.creawor.cbsms.model.CbsBsc; import com.creawor.cbsms.model.CbsBscCells; import com.creawor.cbsms.model.CbsChannel; import com.creawor.cbsms.model.CbsEvent; import com.creawor.cbsms.model.CbsUserRegister; import com.creawor.cbsms.service.CbsEventManager; import com.creawor.security.model.PermUser; public class EventRecord { // 保存時要記錄事件的對象 private static String[] saveEntitysFireEvent = { "CbsBscCells", "CbsChannel", "CbsBsc" }; // 刪除時要記錄事件的對象 private static String[] deleteEntitysFireEvent = { "CbsBscCells", "CbsChannel", "CbsBsc" }; // 更新時要記錄事件的對象 private static String[] updateEntitysFireEvent = { "CbsBscCells", "CbsChannel", "CbsBsc" }; // 包的前綴，反射得到類時使用 private static String prefixPackageName = "com.creawor.cbsms.model."; // 記錄該次操作的登錄用戶名：EventRecord為session范圍 private String userName; // 調(diào)用函數(shù)的前綴，反射執(zhí)行函數(shù)時使用 private static String prefixMethodName = "recordFor"; // 執(zhí)行save時，事件描述 private static String saveInfo = "創(chuàng)建"; // 執(zhí)行delete時，事件描述 private static String deleteInfo = "刪除"; // 執(zhí)行update時，事件描述 private static String updateInfo = "修改"; private CbsEventManager cbsEventManager; // spring自動注入 public void setCbsEventManager(CbsEventManager cbsEventManager) { this.cbsEventManager = cbsEventManager; } public void recordForCbsChannel(String desc, CbsChannel channel) { StringBuffer eventDesc = new StringBuffer(desc); eventDesc.append("頻道" + channel.getChannelName()).append("[").append( channel.getChannelNum()).append("]"); record(eventDesc.toString(), null); } public void recordForCbsBscCells(String desc, CbsBscCells cell) { StringBuffer eventDesc = new StringBuffer(desc); eventDesc.append("小區(qū)"+cell.getCellName()).append("[").append( cell.getCellId()).append("]"); record(eventDesc.toString(), null); } <wbr>public void record(String eventDesc, String eventOrigin) { <wbr><wbr> CbsEvent event = new CbsEvent(); <wbr><wbr> event.setEventDesc(userName + "<wbr><wbr> " + eventDesc); <wbr><wbr> event.setEventOrigin(eventOrigin); <wbr><wbr> event.setStartTime(new Timestamp(System.currentTimeMillis())); <wbr><wbr>cbsEventManager.save(event); <wbr>} public void setUserName(String userName) { this.userName = userName; } public static String[] getDeleteEntitysFireEven<wbr>t() { return deleteEntitysFireEvent; } public static String[] getSaveEntitysFireEvent() { return saveEntitysFireEvent; } public static String[] getUpdateEntitysFireEven<wbr>t() { return updateEntitysFireEvent; } public static String getPrefixPackageName() { return prefixPackageName; } public static void setPrefixPackageName(String prefixPackageName) { EventRecord.prefixPackageName = prefixPackageName; } public static String getPrefixMethodName() { return prefixMethodName; } public static String getDeleteInfo() { return deleteInfo; } public static String getSaveInfo() { return saveInfo; } public static String getUpdateInfo() { return updateInfo; } }</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
    

<wbr>其中EventRecord 在spring中的配置為：</wbr>

      <bean id="eventRecord" class="com.creawor.cbsms.event.EventRecord" scope="session" />
    

<wbr>EventRecord 為session范圍可以使字段userName記錄每次登錄人員的姓名</wbr>

具體在每次登錄后從spring容器中得到EventRecord然后set其userName即可！

最后一步要想讓session范圍生效還要在web.xml中添加配置：

      <web-app> ... <listener> <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class> </listener> ... </web-app>
    

<wbr>這樣如果想要記錄一個業(yè)務(wù)bean增刪改的操作只需在EventRecord中設(shè)置saveEntitysFireEvent，deleteEntitysFireEvent，updateEntitysFireEvent屬性即可，同樣也可使用配置文件配置，這樣都可以使日志和事件的記錄變得很簡單！</wbr>
