java - 在 java 中生成 jssecacerts 的问题

标签 java ssl ldap jsse unboundid-ldap-sdk

如果这似乎是重复的问题，我深表歉意，我担心的是 - 我已经验证了所有帖子，即使我无法生成 jssecacerts 文件。

这是我生成 jssecacerts 的代码，

我在 eclipse 中使用命令行参数运行了上面的类

enter image description here

执行时会抛出以下异常，

你能告诉我我是否遗漏了任何东西或做错了什么。

最佳答案

在浪费了一整天之后，我发现了我的错误..

为了进行 SSL 握手 - 我们需要先在服务器端安装 SSL 证书

我已经安装好了，现在一切正常
