英文:
FileUpload during HttpRequest
问题
I'm trying to do an HTTP GET taking a parameter from the URL and then search into 2 files and send back the information to the user.
I've tried the Java code in a Main Test without any server or request, and it works without any problem, and also the taking of parameters from the URL works.
Error Message:
HTTP Status 500 – Internal Server Error
Type Exception Report
Message org.glassfish.jersey.server.ContainerException: java.io.FileNotFoundException: \AutoCompilersz\src\net\codejava\ws\italy_cap.json (Impossibile trovare il percorso specificato)
Description The server encountered an unexpected condition that prevented it from fulfilling the request.

There are other classes made because the file is a Json Array of Objects.

我是这样解决的：
try (InputStream is = getClass().getResourceAsStream("/resource/italy_cap.json")) {
InputStreamReader isr = new InputStreamReader(is);
JsonReader reader = new JsonReader(isr);
Gson g = new Gson();
p = g.fromJson(reader, Foglio1.class);
}
英文:
I solved it like this:
try (InputStream is = getClass().getResourceAsStream("/resource/italy_cap.json")) {
InputStreamReader isr = new InputStreamReader(is);
JsonReader reader=new JsonReader(isr);
Gson g = new Gson();
p=g.fromJson(reader, Foglio1.class);
