org.testng.TestNGException 尝试访问 PoolingHttpClientConnectionManager

Question

所以我最近开始面对 TestNGException，同时尝试使用 IDE 运行我们现有的测试套件。最近我的意思是更新 intelliJ 和依赖项以尝试在最新版本上工作。失败的代码和堆栈跟踪如下 -

代码用法

ITests.java -

public class ITests extends BaseTest {
    private final Action action = new Action();
}

BaseTest（只是为了共享语法）-

public class BaseTest {
    // where in this class does not use any instance of Http
}

Action.java -

public class Action {
    private final Http http = Http.getInstance();
}

Http.java -

public class Http {

    private static final Http INSTANCE = new Http(); //line 36

    public static Http getInstance() {
        return INSTANCE;
    }

    private Http() {
        PoolingHttpClientConnectionManager connectionManager = new PoolingHttpClientConnectionManager(); //line 43
        connectionManager.setMaxTotal(100);
        connectionManager.setDefaultMaxPerRoute(100);
        RequestConfig defaultRequestConfig = RequestConfig.custom()
                .setSocketTimeout(60000)
                .setConnectTimeout(60000)
                .setConnectionRequestTimeout(60000)
                .build();
        this.client = HttpClients.custom().setDefaultRequestConfig(defaultRequestConfig)
                .setConnectionManager(connectionManager).build();
    }
}

Maven 依赖 -

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.2</version>
</dependency>

注意 - 我们的项目基于 Maven，所以当我使用 maven exec:java 执行测试时，执行正常.

请询问是否需要任何其他信息。

正如@hunter 所问，调试以从加载位置获取 Cpool 的确切路径。已评估 -

Class.forName("org.apache.http.impl.conn.CPool").getResource‌("CPool.class")

结果 -

file:/Users/xyz/.m2/repository/org/apache/httpcomponents/httpclient/4.5.2/httpclient-4.5.2.jar!/org/apache/http/impl/conn/CPool.class

编辑 3 - intelliJ IDEA - 15.0.3 [社区] - 2016 年 1 月 19 日更新

更倾向于 intelliJ，共享日志 post 运行使用 testng.xml -> right click -> run

进行测试

Answer 1

在 IDEA 中，Maven 项目选项卡，单击 Show dependencies 按钮（它会显示一个图表），然后按 Ctrl+ F 在该图中并键入 httpcore 并检查版本。如果显示版本小于 4.4 ，你可以分析依赖是如何解决的。在此基础上，您可以调整 pom 来纠正依赖关系。由于它在命令行中使用 mvn，这可能是 IDEA 通过其 Maven 插件解析 Maven 依赖项的不正确行为。
