过滤器代码如下：

@Componentpublic class SimpleCORSFilter implements Filter {    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {        HttpServletResponse response = (HttpServletResponse) res;        response.setHeader("Access-Control-Allow-Origin", "*");        response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");        response.setHeader("Access-Control-Max-Age", "3600");        response.setHeader("Access-Control-Allow-Headers", "x-requested-with");        chain.doFilter(req, res);    }    public void init(FilterConfig filterConfig) {}    public void destroy() {}}

web.xml配置：

    <filter>      <filter-name>cors</filter-name>      <filter-class>com.app.filter.SimpleCORSFilter</filter-class>    </filter>    <filter-mapping>      <filter-name>cors</filter-name>      <url-pattern>/*</url-pattern>    </filter-mapping>

另外jsonp也可解决跨域问题，
