Question

我有一个java spring / hibernate Web应用程序，并试图添加Junit测试。我设置Junit如下：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:applicationContext.xml" })

结果是applicationContext.xml中的以下行导致了问题：

<bean id="sftpImpl" class="com.zehon.sftp.SFTPClient"/>

如果没有这一行，所有bean都可以正常启动，我可以用它们运行测试。有趣的是，应用程序运行正常，我可以使用sftp客户端与我的应用程序。只有在与JUnit结合使用时才会出现问题，并且在测试启动期间测试失败并显示以下堆栈跟踪：

由于它抱怨构造函数，这里是zehon_file_transfer-1.1.6.jar上javap输出的一部分：

Compiled from "SFTPClient.java"
public class com.zehon.sftp.SFTPClient extends com.zehon.FileTransferClient{
    public com.zehon.sftp.SFTPClient();
    public com.zehon.sftp.SFTPClient(java.lang.String, java.lang.String, java.lang.String);
    public com.zehon.sftp.SFTPClient(java.lang.String, int, java.lang.String, java.lang.String);
    public com.zehon.sftp.SFTPClient(java.lang.String, java.lang.String, java.lang.String, boolean);
    public com.zehon.sftp.SFTPClient(java.lang.String, int, java.lang.String, java.lang.String, boolean);
    public java.lang.String getServerName();
    ...

任何想法如何让这个问题消失？

原来问题是与Eclipses Junit运行时类路径不包括maven“提供”依赖，这是我所包含的这种特定依赖的情况。

我在这个新问题中重申了这个问题：https://stackoverflow.com/questions/20061247/eclipse-junit-class-path-does-not-include-maven-artifacts-of-provided-scope。
