Download jersey library via maven solved the problem for me.
通过 maven 下载球衣库为我解决了这个问题。
To create a RESTFul service:
创建 RESTFul 服务：
- Select "New Project"
- Select "Java"
- Check "Application Server" and "RESTFul Web Service"
- Select "Set up library later"
- Click "Next"
- Click "Finish"
- Right-click on the project name
- Select "Add Framework support..."
- Check "Maven" in the list and "Ok"
Add the following lines to the file pom.xml:
<dependencies> <dependency> <groupId>com.sun.jersey</groupId> <artifactId>jersey-server</artifactId> <version>1.18.1</version> </dependency> </dependencies>
- 选择“新建项目”
- 选择“Java”
- 勾选“应用服务器”和“RESTFul Web 服务”
- 选择“稍后设置库”
- 点击下一步”
- 点击“完成”
- 右键单击项目名称
- 选择“添加框架支持...”
- 选中列表中的“Maven”并“确定”
将以下行添加到文件 pom.xml 中：
<dependencies> <dependency> <groupId>com.sun.jersey</groupId> <artifactId>jersey-server</artifactId> <version>1.18.1</version> </dependency> </dependencies>

Alternatively, change the version of the Jersey library on your Module settings page. Apparently they removed the HttpServerFactory on later versions...
或者，在模块设置页面上更改 Jersey 库的版本。显然他们在更高版本中删除了 HttpServerFactory ......
To change the version, right click on your module and select 'Open Module Settings (F4)'. From there on click Libraries on the left, select jersey from the library list, then click "Change Version". v1.12 worked for me.
要更改版本，请右键单击您的模块并选择“打开模块设置 (F4)”。从那里单击左侧的库，从库列表中选择球衣，然后单击“更改版本”。v1.12 为我工作。
