在SSH框架中添加登录拦截器 开发项目中经常需要用到的用户登录，平时我们都是用页面判断会议是否存在的情况去判断用户是否是登录状态，但是这样有一个弊端，万一有人知道了后台的行动的访问地址可以直接访问去获取，所以在SSH框架中最好去选择去写一个登录拦截器去拦截没有进行登录的用户不允许访问的行动，以下是添加拦截器的过程：如图1所示，首先我们需要创建一个关于登录的拦截器它需要继承MethodFilterInterceptor直接上代码... 阅读详情

1. 添加拦截器类AjaxFilter

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
*允许跨域访问
*/
public class AjaxFilter implements Filter {
public void destroy() {

}

public void doFilter(ServletRequest req, ServletResponse res,
FilterChain chain) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) req;
HttpServletResponse response = (HttpServletResponse) res;
response.setHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Allow-Methods", "POST,GET,OPTIONS,DELETE");
response.setHeader("Access-Control-Max-Age", "3600");
response.setHeader("Access-Control-Allow-Headers", "x-requested-with,Content-Type");
chain.doFilter(request, response);
}

public void init(FilterConfig arg0) throws ServletException {
}

}

2.配置web.xml

<filter>
<filter-name>ajaxFilter</filter-name>
<filter-class>com.a.filter.AjaxFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>ajaxFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
