mysql数据库里面的int型用hibernate反转类型问题

我用hibernate反转mysql数据库，表里面的int型在实体类里面成了Integer类型，手动改写成int型(映射表里面type属性java.lang.Integer删掉了)，报如下错误：
javax.servlet.ServletException: java.lang.NoSuchMethodError: com.computer.bean.Computerinfo.getId()Ljava/lang/Integer;
org.apache.jasper.runtime.PageContextImpl.doHandlePageException(PageContextImpl.java:850)

怎么解决？

Answer 1

你干嘛要手动改成Integer？一个是hibernate类型，一个是java类型，hibernate是没有int类型，你把它改成int型能不错？
