struts2拦截器将用户操作日志存入数据库

struts2拦截器--将用户操作日志存入数据库1.建表，如下所示：

2.新建OperationLogModel.java，其具有上述属性。

3.自动生成PO

4.在struts.xml中配置拦截器：

<interceptors>

<interceptorname="logger"class="com.bfw.crms.log.LogInterceptor"/>

<interceptor-stackname="myInterceptor">

<interceptor-refname="defaultStack"></interceptor-ref>

<interceptor-refname="logger"></interceptor-ref>

</interceptor-stack>

</interceptors>

5.如下例子中的用户登录和修改密码，要在相应xml文件中加入<interceptor-refname="myInterceptor"/>，即：

<!--系统登录-->

<actionname="login"class="systemAction"method="login">

<resultname="login"type="redirect-action">index</result><!--redirect-action是直接转向index.action-->

<interceptor-refname="myInterceptor"/>

</action>

<!--修改密码-->

<actionname="changePassword"class="systemAction"method="changePassword">

<resultname="success"type="redirect-action">changePasswordPre</result>

<interceptor-refname="myInterceptor"/>

</action>

6.在项目中新建文件夹log，在其下新建类LogInterceptor.java，如下：packagecom.bfw.crms.log;

importjava.util.Map;

importjavax.servlet.http.HttpServletRequest;

importjavax.servlet.http.HttpSession;

importmons.lang.StringUtils;

importorg.apache.log4j.Logger;

importcom.bfw.crms.action.BulletinAction;

importcom.bfw.crms.action.SystemAction;

importcom.bfw.crms.model.EmployeeModel;

importcom.bfw.crms.model.OperationLogModel;

importcom.bfw.crms.po.OperationLog;

importcom.bfw.crms.util.BeanUtil;

importcom.bfw.crms.util.DateTimeUtil;

importcom.ninetowns.framework.dao.ObjectDao;

importcom.opensymphony.xwork2.Action;

importcom.opensymphony.xwork2.ActionInvocation;
