我使用JBoss 6.4 EAP和Resteasy 2.3.10 Final和jaxrs api spec 1.1(所有这些库都已在容器中提供)。
我想念ContainerResponseFilter,因为它包含在jaxrs 2.0规范中,因此SO question在我的情况下不起作用。 我可以使用哪种方法来启用CORS?

我必须以这种方式实现标准的javax.servlet.Filter:
package javax.servlet;
import java.io.IOException;
import javax.servlet.annotation.WebFilter;
import javax.servlet.http.HttpServletResponse;
@WebFilter(urlPatterns="/*")
public class ApiOriginFilter implements Filter {
@Override
public void init(FilterConfig filterConfig) throws ServletException {
}
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException {
HttpServletResponse res = (HttpServletResponse) response;
res.addHeader("Access-Control-Allow-Origin", "*");
res.addHeader("Access-Control-Allow-Methods", "GET, POST, DELETE, PUT");
res.addHeader("Access-Control-Allow-Headers", "Content-Type, api_key, Authorization");
chain.doFilter(request, response);
}
@Override
public void destroy() {
}
}
