Struts2 之拦截器配置方法

SecurityInterceptor.java 文件必须继承AbstractInterceptor

 

public class SecurityInterceptor extends AbstractInterceptor {

@Override

public String intercept(ActionInvocation arg0) throws Exception {

Map<String, Object> session = arg0.getInvocationContext().getSession();

if (session.get("loginUser") == null) {

return "login";

} else {

arg0.invoke();

}

return null;

}

}

struts.xml中的配置

<interceptors>

<interceptor name="SecurityInterceptor" class="com.hw.action.SecurityInterceptor" />

</interceptors>

<global-results>

<result name="login">/login.jsp</result>

</global-results>
