當我調用使用http.post要求通過Angular2我的服務，我得到無法啓用CORS的JAX-RS Web服務
Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:3000' is therefore not allowed access.
我的JAX-RS服務
@Override
@POST
@Path("/getWsCallReports")
@Produces(MediaType.APPLICATION_JSON)
public Response getWsCallReports(Query query) {
try {
LOG.info("getWsCallReports called for " + query);
return Response.status(200)
.header("Access-Control-Allow-Origin", "*")
.header("Access-Control-Allow-Headers", "origin, content-type, accept, authorization")
.header("Access-Control-Allow-Credentials", "true")
.header("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS, HEAD")
.header("Access-Control-Max-Age", "1209600").entity(wsCallReportDao.getReports(query)).build();
} catch (Exception e) {
return Response.serverError().build();
}
}
而且我已經試過添加簡單的HTTP過濾器，爲所有請求定義所有必需的標頭
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
HttpServletResponse response = (HttpServletResponse) servletResponse;
// TODO: development only
response.addHeader("Access-Control-Allow-Origin", "*");
response.addHeader("Access-Control-Allow-Headers", "origin, content-type, accept, authorization");
response.addHeader("Access-Control-Allow-Credentials", "true");
response.addHeader("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS, HEAD");
response.addHeader("Access-Control-Max-Age", "1209600");
filterChain.doFilter(servletRequest, servletResponse);
}
但它沒有他LP。我究竟做錯了什麼？
爲了以防萬一，我使用的是Java EE 6，但我無法實現ContainerResponseFilter。我相信沒有它就可以完成。
