springMVC自定義跨域過濾解決方法
一、自定義filter
public class ESTFilter implements Filter {
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
String hm = ((HttpServletRequest) req).getMethod();
HttpServletResponse response = (HttpServletResponse) res;
response.setHeader("Access-Control-Allow-Origin", "*");
Advertisements
response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTI ONS, DELETE");
response.setHeader("Access-Control-Max-Age", "3600");
response.addHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
chain.doFilter(req, res);
}
public void init(FilterConfig filterConfig) {
Advertisements
}
public void destroy() {
}
}
1、 *表示所有域名都可以訪問，如果想指定固定域名可以這樣配置http://eshengtai.net,http://www.eshengtai.net中間一定要用逗號分隔
二、配置web.xml Filter配置，解決跨域問題
<filter>
<filter-name>eshengtaiFilter</filter-name>
<filter-class>com.xx.ESTFilter </filter-class>
</filter>
<filter-mapping>
<filter-name>eshengtaiFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
