java - 与本地主机的 HTTP 连接失败

Question

我有一个 Java 应用程序向 Jetty 服务器发出 REST 请求。

如果我使用真实的 DNS 名称连接到服务器，它会工作，但是当我想向本地主机上的本地测试实例发出请求时，出现以下异常:

Caused by: com.sun.jersey.api.client.ClientHandlerException: java.io.IOException: Stream closed
    at com.sun.jersey.api.client.ClientResponse.hasEntity(ClientResponse.java:480) ~[jersey-client-1.14.jar:1.14]

浏览器中的请求和我的 REST 工具工作。

当我为本地主机使用 IPv6 地址时，它开始工作:https://[0:0:0:0:0:0:0:1]/

它对我来说总是适用于 localhost。是否有可能某些 Java 或 Windows 7 更新更改了默认设置，因此它改用 IPv6？

我该怎么做才能让 localhost 再次工作，我是否需要担心这可能会在其他 PC 想要连接到我们的真实服务器时造成问题？

我想兼容 IPv4 和 IPv6。

编辑:这是我的主机文件(未经编辑)

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host

# localhost name resolution is handled within DNS itself.
#   127.0.0.1       localhost
#   ::1             localhost

Answer 1

所以我终于找到了问题所在。显然 Skype 使用端口 80 和 443 作为备用端口。我一退出 Skype，一切正常。

WebApp accessible via localhost but not 127.0.0.1

它可能适用于 IPv6 本地主机地址，因为 Skype 未绑定(bind)到该地址。
