Spring3使用CORS解決跨域請求的配置

Spring3使用CORS解決跨域請求的配置

1.以下是過濾器的代碼：

/**
 * CORS過濾器
 * 
 * @author hkb <br>
 */
public class CorsFilter implements Filter {

    /*
     * @see javax.servlet.Filter#init(javax.servlet.FilterConfig)
     */
    public void init(FilterConfig filterConfig) throws ServletException {

    }

    /*
     * @see javax.servlet.Filter#doFilter(javax.servlet.ServletRequest,
     * javax.servlet.ServletResponse, javax.servlet.FilterChain)
     */
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {
        HttpServletResponse httpServletResponse = (HttpServletResponse) response;
        httpServletResponse.setHeader("Access-Control-Allow-Origin", "*");
        httpServletResponse.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
        httpServletResponse.setHeader("Access-Control-Max-Age", "3600");
        httpServletResponse.setHeader("Access-Control-Allow-Headers",
                "Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With");
        httpServletResponse.setHeader("Access-Control-Allow-Credentials", "true");// 允許cookie
        chain.doFilter(request, response);
    }

    /*
     * @see javax.servlet.Filter#destroy()
     */
    public void destroy() {

    }

}

2.以下是web.xml中的配置

<!-- CORS過濾器start -->
    <filter>
        <filter-name>corsFilter</filter-name>
        <filter-class>org.food.filter.CorsFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>corsFilter</filter-name>
        <url-pattern>*.do</url-pattern>
    </filter-mapping>
<!-- CORS過濾器end -->
