springMVC4.1及以下，就需要对该请求配置filter,,设置请求头可支持跨域

1.web.xml配置

<filter>
<filter-name>header</filter-name>
<filter-class>com.foriseland.fsoa.pay.filter.HeaderFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>header</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

2自定义filter拦截请求，添加跨域请求支持

package com.foriseland.fsoa.pay.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.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;/**
* 头部过滤器
* @author
*/
public class HeaderFilter 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;
String originHeader = request.getHeader("Origin");
response.setHeader("Access-Control-Allow-Origin", originHeader);
response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
response.setHeader("Access-Control-Max-Age", "0");
response.setHeader("Access-Control-Allow-Headers", "Origin, No-Cache, X-Requested-With, If-Modified-Since, Pragma, Last-Modified, Cache-Control, Expires, Content-Type, X-E4M-With,userId,token");
response.setHeader("Access-Control-Allow-Credentials", "true");
response.setHeader("XDomainRequestAllowed","1");
response.setHeader("XDomainRequestAllowed","1");
chain.doFilter(request, response);
} public void init(FilterConfig arg0) throws ServletException { }
}
