spring实现拦截登录请求

在做项目的过程中，都会涉及到用户的登录注册，访问一个请求时，有时还要判断用户是否已经登录。现在我们一拦截器的方式，来实现拦截操作。

首先需要定义要拦截哪些请求地址

// 拦截的地址
private static final String[] IGNORE_URL={"SecurySet.action","SetMobileSecond.action","MyInvest.action","MyFlowFund.action","InvestStatistics.action","myAllGiftVoucher.action","AutomaticBidSet.action"};

这一块是我的要拦截的地址

具体的方法实现如下：

public class LoginInterceptor extends HandlerInterceptorAdapter{

// 拦截的地址
private static final String[] IGNORE_URL={"SecurySet.action","SetMobileSecond.action","MyInvest.action","MyFlowFund.action","InvestStatistics.action","myAllGiftVoucher.action","AutomaticBidSet.action"};

@Override
public boolean preHandle(HttpServletRequest request,
HttpServletResponse response, Object handler) throws Exception {
boolean falg=false;
String url=request.getRequestURL().toString();
//拦截上面的路径
for (String str : IGNORE_URL) {
if(url.contains(str)){
falg=true;
break;
}
}
if(falg){
Aaccount account = (Aaccount) request.getSession().getAttribute("accountSession");
if(account!=null){
falg=true;
}else {
response.sendRedirect("/Apcgc/Login.action");
return false;
}
}
return true;
}
}

在spring中配置

<mvc:interceptors>

<mvc:interceptor>

<mvc:mapping path="/**"/>

<bean class="com.immense.tw.interceptor.LoginInterceptor"></bean>

</mvc:interceptor>

</mvc:interceptors>
