SSH中的Aop使用

DAo层:
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.orm.hibernate3.*;
public class UserDao extends HibernateDaoSupport {
public User queryUserByID(String uid){
User user=null;
HibernateTemplate template=this.getHibernateTemplate();
user=(User)template.get(User.class, uid);
return user;
}
}
bo层:
IUser.java:
public interface IUserBO {
public boolean login(String id,String pwd);
}
UserBo.java:
public class UserBo implements IUserBO {
private UserDao dao=null;
private User loginUser=null;
private String msg="";
public void setDao(UserDao dao) {
this.dao = dao;
}
public boolean login(String id,String pwd){
boolean rtn=false;
User temp= dao.queryUserByID(id);
if(temp!=null){
if(temp.getUserPwd().equals(pwd)){
this.setLoginUser(temp);
this.msg="登陆成功！！！";
rtn=true;
}else{
this.msg="密码不正确!!!";
}
}else{
this.msg="未找到该用户!!!";
}
return rtn;
}
public User getLoginUser() {
return loginUser;
}
private void setLoginUser(User user) {
this.loginUser=new User();
loginUser.setUserID(user.getUserID());
loginUser.setUserName(user.getUserName());
loginUser.setUserPwd(user.getUserPwd());
}
public String getMsg() {
return msg;
}
}
测试bo:
public class Test {
public static void main(String[] args) {
ApplicationContext ctx=new FileSystemXmlApplicationContext ("/Webroot/WEB-INF/beans.xml");
TestDao dao=(TestDao) ctx.getBean("testdao");
List list=dao.query();
for(Object obj :list){
Book temp=(Book)obj;
System.out.println(temp.getBookName()+":");
Set set= temp.getAuthorset();
for(Object child:set){
Author childnode=(Author)child;
System.out.println(childnode.getAuthorName());
}
}
}
}
model层我就省略了
util层:使用aop方法后通知的代理机制
SafeLogger.java:
public class SafeLogger implements AfterReturningAdvice {
public void afterReturning(Object result, Method method, Object[] args, Object target) throws Throwable {
String methodName=method.getName();
if(methodName.equals("login")){
boolean flag= Boolean.parseBoolean(result.toString());
if(flag){
String uid= args[0].toString();
Logger logger=Logger.getRootLogger();
logger.warn("用户"+uid+"已登陆");
}
}
}
}
web层:
ActionForm我省略了没什么可说的
Action:
public class LoginAction extends Action {
private IUserBO bo;
public void setBo(IUserBO bo) {
this.bo = bo;
}
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
//1
LoginForm loginForm = (LoginForm) form;
boolean flag=false;
//2
if(bo.login(loginForm.getLoginID(), loginForm.getLoginPwd())){
flag=true;
}
//3
if(flag){
return mapping.findForward("success");
}else{
return mapping.findForward("failure");
}
}
}
struts-config.xml配置文件
<struts-config>
<data-sources />
<form-beans >
<form-bean name="loginForm" type="lee.web.LoginForm" />
</form-beans>
<global-exceptions />
<global-forwards />
<action-mappings >
<action attribute="loginForm" input="/login.jsp" name="loginForm" path="/login" scope="request" type="org.springframework.web.struts.DelegatingActionProxy" validate="true" >
<forward name="success" path="/main.jsp" />
<forward name="failure" path="/error.jsp" />
</action>
</action-mappings>
<message-resources parameter="lee.web.UsersResources" />
<plug-in className="org.apache.struts.validator.ValidatorPlugIn">
<set-property property="pathnames" value="/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml"/>
</plug-in>
<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property property="contextConfigLocation" value="/WEB-INF/beans.xml" />
</plug-in>
</struts-config>
最后是spring的配置文件:
<?xml version="1.0" encoding="UTF-8"?>

<beans>
