我对hibernate很新，我遇到了这个例外。就我的理解而言，如果我的方言是正确的并且我很安静我确定我正在使用正确的方言即org.hibernate.dialect.MySQLDialect，这仍然不应该发生，我仍然尝试使用org.hibernate.dialect.MySQLInnoDBDialect但它仍然给出相同的例外。我使用spring 3.1.0 with hibernate 3和mysql 5.导致此错误的dao函数是：
@SuppressWarnings("unchecked")
protected List<T> findByCriteria(Criterion... criterion) {
Criteria crit = getSession().createCriteria(getPersistentClass())
.addOrder(Order.asc(getDefaultProperty()));
for (Criterion c : criterion) {
crit.add(c);
}
List<T> critList=crit.list();
return critList;
}
我经常搜索，并且在可能的问题上几乎碰壁了。所以任何帮助都将不胜感激。
修改 完整的堆栈跟踪
我已启用日志记录并发布我认为存在问题的部分

首先，你的方言是错的。对于MySQL 5，您需要使用org.hibernate.dialect.MySQL5Dialect。 MySQL 5 InnoDB方言是org.hibernate.dialect.MySQL5InnoDBDialect。
此异常清楚地告诉您错误的原因：
引起：com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException： 您的SQL语法有错误;检查手册 对应于您的MySQL服务器版本，以便使用正确的语法 在'match this_ left outer join ref_country country2_附近 this_.country1_id = country2_'在第1行
你的Hibernate SQL：
