SSLContext.getInstance中的NoSuchAlgorithmException

Question

我得到NoSuchAlgorithmException以下代码：

 @RunWith(PowerMockRunner.class)
 @PrepareForTest({CloudWatchHelper.class})
 class MyTest {
 ....
 final SSLContext sslcontext = SSLContext.getInstance("TLS");
 ...
 }

堆栈跟踪：

[junit] class configured for SSLContext: sun.security.ssl.SSLContextImpl$TLSContext not a SSLContext
[junit] java.security.NoSuchAlgorithmException: class configured for SSLContext: sun.security.ssl.SSLContextImpl$TLSContext not a SSLContext
[junit]     at sun.security.jca.GetInstance.checkSuperClass(GetInstance.java:260)
[junit]     at sun.security.jca.GetInstance.getInstance(GetInstance.java:237)
[junit]     at sun.security.jca.GetInstance.getInstance(GetInstance.java:164)
[junit]     at javax.net.ssl.SSLContext.getInstance(SSLContext.java:156)

我想知道背后的原因是什么NoSuchAlgorithmException。

Answer 1

在我的测试类中添加以下批注为我解决了此问题：

@PowerMockIgnore({ "javax.net.ssl.*", "javax.security.*" })

Answer 2

我意识到我得到例外是因为：

 @RunWith(PowerMockRunner.class)
 @PrepareForTest({CloudWatchHelper.class})
