struts2攔截器--將用戶操作日志存入數(shù)據(jù)庫1.建表，如下所示：

2.新建OperationLogModel.java，其具有上述屬性。

3.自動(dòng)生成PO

4.在struts.xml中配置攔截器：

<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.如下例子中的用戶登錄和修改密碼，要在相應(yīng)xml文件中加入<interceptor-refname="myInterceptor"/>，即：

<!--系統(tǒng)登錄-->

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

<resultname="login"type="redirect-action">index</result><!--redirect-action是直接轉(zhuǎn)向index.action-->

<interceptor-refname="myInterceptor"/>

</action>

<!--修改密碼-->

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

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

<interceptor-refname="myInterceptor"/>

</action>

6.在項(xiàng)目中新建文件夾log，在其下新建類LogInterceptor.java，如下：packagecom.bfw.crms.log;

importjava.util.Map;

importjavax.servlet.http.HttpServletRequest;

importjavax.servlet.http.HttpSession;
