我写了一个用于加载性能的 java 代码，我用 google url 编译它执行成功但是我输入了我的没有 ssl 证书的 url，代码不执行并且它显示这个异常，

Answer 1

根据 JMeter 文档的 SSL 加密 章节：

JMeter HTTP 采样器配置为接受所有证书，无论是否受信任，无论有效期等如何。 这是为了在测试服务器时提供最大的灵活性。

这意味着如果你使用 HTTP Request 采样器，即使服务器端证书有问题，它也会成功执行。

如果您编写了自己的 Java 代码并尝试在 JSR223 测试元素 中使用它或尝试 创建 JMeter 插件 您可以创建一个特殊的 SSLSocketFactory，它将信任所有证书，如 Trusting all certificates using HttpClient over HTTPS 线程

无论如何，如果没有看到您的完整代码，我们无法提供全面的帮助。
