LoginService - 仅限createUser（）方法
public boolean createUser(UserBean userBean)
{
userModel=UserHelper.convertBeanToModel(userBean);
ItemModel itemModel= new ItemModel();
itemModel.setItemName("Q");
itemModel.setItemType("Q");
itemModel.setItemSubType("Q");
itemModel.setItemDescription("Q");
itemModel.setItemCompanyName("Q");
try{
Session session=getSession();
session.beginTransaction();
session.save(itemModel);
session.save(userModel);
session.getTransaction().commit();
session.close();
}
catch(ConstraintViolationException e)
{
return false;
}
return true;
}
除此之外，你可能想知道的一些事情是：
1）我使用的是MySQL 5.2.37版本。
2）如果我只坚持userModel，应用程序运行绝对正常，对于ItemModel howerver似乎有一些我无法理解的问题（）
3）b / w userModel和itemModel没有太大的区别，只是在itemModel中有一个生成策略
我试过的策略包括将hbm2ddl.auto更改为＆＃34; create-drop＆＃34; ，将Dialect改为MySQL5InnoDb，我希望这不是MYSQL的缺陷，而且是我的一些错误。请帮我解决这个问题，（如果这个问题没有得到解决，我可能会死，严重的事情。）
答案 0 :(得分：0)
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'pms.itemmodel' doesn't exist
例外情况表明名称没有表格＆＃34; pms.itemmodel＆＃34;。
我注意到的一些事情如下：
以下是您的班级声明。您已在包＆＃34; com.project.pms.model＆＃34;中定义了ItemModel。
package com.project.pms.model;
@Entity
public class ItemModel
{
但是在packagesToScan中你定义为
<property name="packagesToScan" value="com.project.pms"></property>
＆＃34; packagesToScan＆＃34;不会查看子包（com.project.pms.model）内部，只会查看指定的包（＆＃34; com.project.pms＆＃34;）。
此外，您的实体类没有@Table（name =＆＃34; some-name＆＃34;）注释。这意味着您的不合格类名称＆＃39; ItemModel＆＃39;并且表名是相同的。如果它们不包含@Table注释并指定正确的表名。
