JavaWeb项目运行报错：Failed to instantiate [com.sun.tools.xjc.model.Model]

JavaWeb项目运行报错

org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.sun.tools.xjc.model.Model]: No default constructor found; nested exception is java.lang.NoSuchMethodException: com.sun.tools.xjc.model.Model.()

原因：com.sun.tools.xjc.model.Model包初始化失败，发现是导错了包

解决办法：在Controller类中删除import com.sun.tools.xjc.model.Model;

重新导入org.springframework.ui.Model这个包

重启服务器，项目正常。
