Question

我正在使用hibernate进行所有数据库操作。

我的问题是，我想在表格中插入一个包含'的字符串，例如rea9'ea/rea9'ea。插入它时我得到以下异常

Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ea/rea9','6a8b2622d3b8ab7de31c0e2496cef2bd',5840,'')' at line 1 at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)

如何解决问题？

首先，您是否已将表格映射到POJO？当然，这是使Hibernate如此强大的核心所在。如果有，那么插入任何字符串都很简单：

MyPOJO m = new MyPOJO();
m.setName("asdf'!@#$%^&*()\"1234567890");
HibernateUtil.currentSession().save(m);

如果需要在HQL语句中包含任何字符串，那么它应该是一个参数：

HibernateUtil.currentSession().createQuery("from MyTable where Name=:name")
            .setParameter("name","asdf'!@#$%^&*()\"1234567890")
            .list();
