Java HIBERNATE：无法使用HIBERNATE从MySQL提取数据

java mysql hibernate

Java HIBERNATE：无法使用HIBERNATE从MySQL提取数据,java,mysql,hibernate,Java,Mysql,Hibernate,对不起打扰你了。我是hibernate的新手，我有一个愚蠢的问题。我不能独自处理这件事。每次我试图从DB中选择数据时，都会出现语法错误，因此我决定使用虚拟表（但问题与以前相同）：休眠配置文件： <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"

对不起打扰你了。我是hibernate的新手，我有一个愚蠢的问题。我不能独自处理这件事。每次我试图从DB中选择数据时，都会出现语法错误，因此我决定使用虚拟表（但问题与以前相同）：
