Question

当我尝试创建Web服务时，它显示出错误。我使用Apache CXF 2.X来完成这项任务。

我试图贬低这个

Windows - ＆gt;偏好设置 - ＆gt;添加 - ＆gt;添加了CXF 2.x

但问题并没有解决。

这是我的界面代码

@WebService
public interface ISubstraction {
 public int substract(int x, int y)
}

这是我的实施代码

@WebService(endpointInterface ="com.webservice.ISubstraction")
public class SubstractionImpl implements ISubstraction {
  @Override
  public int substract(int x, int y) {
     int z = x-y;
     return z;
 }

}

这是例外
