SpringMVC solve cross-domain AJAX

Set HeaderFilter class

package com.zhangyong.filter;
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.HttpServletResponse;

public class HeaderFilter implements Filter {
    @Override
    public void doFilter(ServletRequest request, ServletResponse resp, FilterChain chain) throws IOException, ServletException {
        HttpServletResponse response = (HttpServletResponse) resp;
        //解决跨域访问报错
        response.setHeader ("Access-Control-Allow-Origin", "*");
        response.setHeader ("Access-Control-Allow-Methods", "POST, PUT, GET, OPTIONS, DELETE");
        //设置过期时间
        response.setHeader ("Access-Control-Max-Age", "3600");
        response.setHeader ("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept, client_id, uuid, Authorization");
        // 支持HTTP 1.1.
        response.setHeader ("Cache-Control", "no-cache, no-store, must-revalidate");
        // 支持HTTP 1.0. response.setHeader("Expires", "0");
        response.setHeader ("Pragma", "no-cache");
        chain.doFilter (request, resp);
    }
    @Override
    public void init(FilterConfig filterConfig) {
    }
    @Override
    public void destroy() {
    }
}

Configuring web.xml

  <!-- 进行消息头的设置,用来解决ajax跨域的问题 -->
    <filter>
        <filter-name>cors</filter-name>
        <filter-class>com.zhangyong.filter.HeaderFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>cors</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
