将项目迁移到 Maven 构建后尝试运行测试时出现以下错误。在没有 Maven 的情况下，使用具有正常构建路径的相同代码进行测试就可以正常工作。

我的测试场景：
@Test
public void test()
{
try {
System.out.println(makeHttpRequest(new URL("http://localhost:8080/json/process"), "[]", DEFAULT_TIMEOUTS));
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
制作HttpRequest：
private static String makeHttpRequest(URL url, String body, int timeout) throws IOException {
HttpURLConnection conn = null;
OutputStream os = null;
InputStream is = null;
String response = null;
byte[] bytes = null;
try {
bytes = body.getBytes("UTF-8");
} catch (Exception e) {
e.printStackTrace();
return null;
}
try {
conn = (HttpURLConnection) (url.openConnection());
conn.setReadTimeout(timeout);
conn.setConnectTimeout(timeout);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
conn.setRequestProperty("Content-Length", "" + bytes.length);
conn.setDoOutput(true);
os = new DataOutputStream(conn.getOutputStream());
os.write(bytes);
os.flush();
os.close();
StringWriter writer = new StringWriter();
is = conn.getInputStream();
IOUtils.copy(is, writer, "UTF-8");
response = writer.toString();
conn.disconnect();
} finally {
if (os != null) {
try {
os.close();
} catch (IOException e) {
}
}
if (is != null) {
try {
is.close();
} catch (IOException e) {
}
}
}
return response;
}
JSON服务：
@POST
@Path("/process")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public Vector<Stuff> getLocations(Vector<Stuff> stuff) {
return processor.process(stuff);
}
