我也遇到了同样的问题，我使用的是8.1.0-3，但后来我使用了9.2.1-0，这个问题在没有任何手动步骤的情况下得到了修复。自签名证书工作正常。

在花了好几个小时试图构建证书文件以使我的Java 6安装能够与新的twitter证书一起工作之后，我终于无意中发现了一个隐藏在留言板上的评论中令人难以置信的简单解决方案。只需从Java 7安装中复制cacerts文件，并覆盖Java 6安装中的cacerts文件。可能最好先备份cacerts文件，但随后只需复制新文件，然后嘣!它就是有用。

注意，我实际上复制了一个Windows cacerts文件到Linux安装中，它工作得很好。

该文件位于旧的和新的Java jdk安装中的jre/lib/security/cacerts中。

希望这能帮别人省下几个小时的麻烦。

对我来说，证书错误弹出是因为我有fiddler运行在后台，这打乱了证书。它作为一个代理如此接近，并重新启动eclipse。

这是一个解决方案，但以我的故事的形式:

我尝试了上面给出的所有解决方案(3天)，几乎要死了，没有一个对我有效。

我失去了所有的希望。

我联系了我的安全团队，因为我在代理服务器后面，他们告诉我他们最近更新了他们的安全策略。

后来他们发布了一个新的“cacerts”文件，其中包含了所有的证书。

我删除了%JAVA_HOME%/jre/lib/security中的cacerts文件，它解决了我的问题。

所以如果你正面临这个问题，它可能来自你的网络团队。

我使用我自己的信任存储，而不是JRE，通过传递arg -Djavax.net.ssl.trustStore=

不管信任库中的certs如何，我都得到这个错误。对我来说，问题是在参数行上传递的属性的顺序。 当我把-Djavax.net.ssl.trustStore=& -Djavax.net.ssl.trustStorePassword=之前-Dspring.config。Location = & -jar args我能够通过https成功调用我的rest调用。

我偶然发现了这个问题，花了很多时间研究来解决，特别是自动生成的证书，与官方证书不同，它非常棘手，Java不太喜欢它们。

请检查以下链接:用Java解决证书问题

基本上，您必须将服务器上的证书添加到Java Home certs中。

Generate or Get your certificate and configure Tomcat to use it in Servers.xml Download the Java source code of the class InstallCert and execute it while the server is running, providing the following arguments server[:port]. No password is needed, as the original password works for the Java certs ("changeit"). The Program will connect to the server and Java will throw an exception, it will analyze the certificate provided by the server and allow you to create a jssecerts file inside the directory where you executed the Program (If executed from Eclipse then make sure you configure the Work directory in Run -> Configurations). Manually copy that file to $JAVA_HOME/jre/lib/security

遵循这些步骤之后，与证书的连接将不再在Java中生成异常。

下面的源代码很重要，它从(Sun) Oracle博客中消失了，我发现它的唯一页面是在提供的链接上，因此我将它附加在答案中以供参考。
