推荐答案
我也遇到了同样的问题.我使用的是 1.12 版.
I have encountered the same issue. I was using Version 1.12.
我在jersey-server-1.12.jar"或jersey-core-1.12.jar"中找不到类 com.sun.jersey.spi.container.servlet.ServletContainer正如其他一些论坛所建议的那样.
I could not find the class com.sun.jersey.spi.container.servlet.ServletContainer in the "jersey-server-1.12.jar" or "jersey-core-1.12.jar" as suggested in some other forums.
您可以在 Eclipse 中轻松检查这一点，当您将其添加到构建路径并注意到您在上述 jar 文件中没有该类时.
You can easily check this in Eclipse, when you add it to the Build Path and notice that you do not have that class in the above mentioned jar files.
我四处寻找，发现如下:
I searched around and found the following:
看起来类 com.sun.jersey.spi.container.servlet.ServletContainer 位于不同的 jar 文件(jersey-servlet-1.12.jar")中.
It looks like the class com.sun.jersey.spi.container.servlet.ServletContainer is in a different jar file ("jersey-servlet-1.12.jar").
我没有找到任何关于此的文档.然而，在我的 WEB-INF/lib 中有这个文件解决了这个问题.
I did not find any documentation about this. However having this file in my WEB-INF/lib resolved this issue.
