当我尝试连接到数据库时，我的junit类出现以下错误，我正在使用powermockrunner进行junit。我尝试连接的驱动程序不是一个众所周知的或开源的，它是我公司定制的驱动程序。是引起问题的那个吗？这些痕迹是：

尝试在类声明上方添加以下注解以及其他注解

@PowerMockIgnore({"javax.management.*"})

你有 @PrepareForTest 在你的测试中？
如果是，那么当您连接时，它引用stub类并抛出expection。
添加 @PowerMockIgnore 要忽略的注解

@RunWith (PowerMockRunner.class)
...
@PowerMockIgnore({"java.sql.*", "javax.management.*", "org.apache.http.conn.ssl.*", "com.amazonaws.*", "javax.net.ssl.*","com.sun.*"})
public class ... {}
