SSH配置攔截器

配置loginInterceptor步驟：

1.

public class CheckLogin implements Interceptor {


public void destroy() {
System.out.println("------CheckLogin.destroy------");
}


public void init() {
System.out.println("------CheckLogin.i------");
}


public String intercept(ActionInvocation arg0) throws Exception {
System.out.println("------CheckLogin.intercept------");

Map session = ActionContext.getContext().getSession();

if(session.get("user.name")!=null) {
return arg0.invoke();
}

return "checkLoginFail";
}
}
