spring4.1及以下跨域配置

springMVC4.1及以下，就需要對該請求配置filter,,設置請求頭可支持跨域

1.web.xml配置

<!-- 跨域問題解決 -->
<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自定義filter攔截請求，添加跨域請求支持

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;
 
/**
 * 頭部過濾器
 * @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 {
        
    }
}

至此，就可以支持跨域訪問了。
