推荐答案
我遇到了相同的问题.我使用的是1.12版.
I have encountered the same issue. I was using Version 1.12.
我在其他论坛中建议的"jersey-server-1.12.jar"或"jersey-core-1.12.jar"中找不到类com.sun.jersey.spi.container.servlet.ServletContainer.
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.
当您将其添加到Build Path并注意到上述jar文件中没有该类时，您可以在Eclipse中轻松地对其进行检查.
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.
我四处搜寻，发现了以下内容:
I searched around and found the following:
看起来类com.sun.jersey.spi.container.servlet.ServletContainer在另一个jar文件中("jersey-servlet-1.12.jar").
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.但是，在我的WEB-INF/lib中拥有此文件可以解决此问题.
I did not find any documentation about this. However having this file in my WEB-INF/lib resolved this issue.
希望这会有所帮助.
