JMeter Java代码执行无SSL证书URL时出现NoSuchMethodError异常

我编写了用于负载性能测试的Java代码，使用Google URL测试时可正常执行，但输入无SSL证书的自有URL时，代码执行失败并抛出如下异常：

问题原因分析 #

这个NoSuchMethodError本质是JMeter HTTPS相关组件的版本不兼容或依赖缺失：

• 访问无SSL证书的URL时，JMeter会触发信任所有证书的逻辑，尝试初始化HC4TrustAllSSLSocketFactory，但该类依赖的HttpSSLProtocolSocketFactory构造方法不存在
• 大概率是项目依赖的JMeter jar包版本与本地安装的JMeter 5.5版本不一致，或者缺少ApacheJMeter_http核心组件
• 也可能存在第三方HTTP客户端库（如httpclient、httpcore）的版本冲突，覆盖了JMeter自带的兼容版本

解决方案 #

1. 统一JMeter依赖版本 #

确保项目中所有JMeter相关依赖版本与本地安装的JMeter 5.5完全一致，以Maven为例：

<dependencies>
    <dependency>
        <groupId>org.apache.jmeter</groupId>
        <artifactId>ApacheJMeter_core</artifactId>
        <version>5.5</version>
    </dependency>
    <dependency>
        <groupId>org.apache.jmeter</groupId>
        <artifactId>ApacheJMeter_http</artifactId>
        <version>5.5</version>
    </dependency>
</dependencies>

2. 显式配置忽略SSL证书验证 #

在JMeter初始化代码后添加以下配置，绕过证书验证逻辑，避免触发不兼容的Socket工厂：

// 忽略SSL证书及主机名验证
JMeterUtils.setProperty("https.socket.protocols", "TLSv1.2");
JMeterUtils.setProperty("javax.net.ssl.trustStore", "dummy");
JMeterUtils.setProperty("javax.net.ssl.trustStorePassword", "dummy");
JMeterUtils.setProperty("https.host.verifier", "org.apache.jmeter.protocol.http.control.NoopHostnameVerifier");

同时给HTTPSamplerProxy指定HTTPS协议：

client.setProtocol("https");

3. 清理依赖冲突 #

检查项目依赖树，排除与JMeter 5.5不兼容的httpclient/httpcore版本，确保使用JMeter自带的版本（JMeter 5.5对应httpclient 4.5.13、httpcore 4.4.14）。
