我构建了一个简单的Jersey休息服务器,它处理一个简单的服务。 在启动服务器的主类中,我读取了我想要的属性文件 提供/传递给jax处理程序类。 服务器工作,我只需要一种方式来共享配置参数 带有请求处理程序的主类。 我怎么能这样做?
...
public HashMap resources;
// this start the listener jersey server...
String host="http://localhost/";
int port = 9998;
URI baseUri = UriBuilder.fromUri(host).port(port).build();
ResourceConfig config = new ResourceConfig();
config.packages(true, "br.com.myserver");
config.register(MyHandler.class);
// I WANT TO ACCESS/SHARE THIS WITH THE HANDLER -> MyHandler.class
resources.put("host_user","bla bla bla");
HttpServer server = JdkHttpServerFactory.createHttpServer(baseUri, config);
System.out.println("--Press Enter to STOP the server--");
System.in.read();
Server.stop(0);
System.out.println("Server stoped!");
...
@Path("myapp")
public class MyHandler
{
@POST @Path("/testep")
@Consumes("application/json")
@Produces("text/plain")
public String action1(@Context Request request, String json)
{
// HERE I WANT TO ACCESS THE RESOUCES HASHMAP OF MAIN HERE
// (how get main handler here).resources.get("host_user");
// maybe access main class, or something like
// the intention is to avoid the read of config at all requests here
System.out.println("received event:" + json);
return "event received " + json;
}
}
任何想法都会被贬低,谢谢。

您使用ResourceConfig
配置property(key, value)
的任何属性都可以通过Configuration
界面访问,您可以将其注入资源类。
ResourceConfig config = new ResourceConfig();
config.property("host_user","bla bla bla");
...
@Path("myapp")
public class MyHandler
{
@Context
Configuration configuration;
public String action1(@Context Request request, String json) {
Map<String, Object> props = configuration.getProperties();
}
}
