我有一个用于 JUnit 4.x 的 Java 类。在每个 @Test 方法中,我创建一个新的 HttpServer,使用端口 9090。第一次调用工作找到,但随后的错误“地址已在使用中:绑定”。
这是一个例子:
@Test
public void testSendNoDataHasValidResponse() throws Exception {
InetSocketAddress address = new InetSocketAddress(9090);
HttpHandler handler = new HttpHandler() {
@Override
public void handle(HttpExchange exchange) throws IOException {
byte[] response = "Hello, world".getBytes();
exchange.sendResponseHeaders(HttpURLConnection.HTTP_OK, response.length);
exchange.getResponseBody().write(response);
exchange.close();
}
};
HttpServer server = HttpServer.create(address, 1);
server.createContext("/me.html", handler);
server.start();
Client client = new Client.Builder(new URL("http://localhost:9090/me.html"), 20, "mykey").build();
client.sync();
server.stop(1);
assertEquals(true, client.isSuccessfullySynchronized());
}
很明显,HttpServer 只包含在每个方法中,并在结束前停止。我看不到是什么继续保持任何套接字打开。第一个测试通过,随后的测试每次都失败。
有任何想法吗?
用更正的方法编辑:
@Test
public void testSendNoDataHasValidResponse() throws Exception {
server = HttpServer.create(new InetSocketAddress("127.0.0.1", 0), 1);
HttpHandler handler = new HttpHandler() {
@Override
public void handle(HttpExchange exchange) throws IOException {
byte[] response = "Hello, world".getBytes();
exchange.sendResponseHeaders(HttpURLConnection.HTTP_OK, response.length);
exchange.getResponseBody().write(response);
exchange.close();
}
};
server.createContext("/me.html", handler);
server.start();
InetSocketAddress address = server.getAddress();
String target = String.format("http://%s:%s/me.html", address.getHostName(), address.getPort());
Client client = new Client.Builder(new URL(target), 20, "mykey").build();
client.sync();
server.stop(0);
assertEquals(true, client.isSuccessfullySynchronized());
}
