定义了一个MyCrossOriginFilter.class,并在Access-Control-Allow-Headers 额外添加了允许"token"，客户端ajax请求带有token时有个别接口不支持跨域了，请求不带token就支持跨域。什么原因呢？
另外，两个不同的Control都定义有相同的@At("/campaign/list") url，会影响跨域请求么？

public class MyCrossOriginFilter implements ActionFilter {
	
	private static final Log log = Logs.get();
	protected String origin;
	protected String methods;
	protected String headers;
	protected String credentials;
	
	public MyCrossOriginFilter() {
		this("*", "GET, POST, PUT, DELETE, OPTIONS, PATCH", "Origin, Content-Type, Accept, Authorization, X-Requested-With,token", "true");
	}
	
	public MyCrossOriginFilter(String origin, String methods, String headers, String credentials) {
		this.origin = origin;
		this.methods = methods;
		this.headers = headers;
		this.credentials = credentials;
	}
	
	public View match(ActionContext ac) {
		HttpServletResponse resp = ac.getResponse();
		if (!Strings.isBlank(this.origin)) {
			resp.setHeader("Access-Control-Allow-Origin", this.origin);
		}
		
		if (!Strings.isBlank(this.methods)) {
			resp.setHeader("Access-Control-Allow-Methods", this.methods);
		}
		
		if (!Strings.isBlank(this.headers)) {
			resp.setHeader("Access-Control-Allow-Headers", this.headers);
		}
		
		if (!Strings.isBlank(this.credentials)) {
			resp.setHeader("Access-Control-Allow-Credentials", this.credentials);
		}
		
		if ("OPTIONS".equals(ac.getRequest().getMethod())) {
			if (log.isDebugEnabled()) {
				log.debugf("Feedback -- [%s] [%s] [%s] [%s]", new Object[]{this.origin, this.methods, this.headers, this.credentials});
			}
			
			return new VoidView();
		}

		return null;
	}
