我是 hibernate 的新手，我被困在这个异常中。据我所知，如果我的方言是正确的，这不应该发生，我很确定我使用的是正确的方言，即 org.hibernate.dialect.MySQLDialect，我仍然尝试使用 org.hibernate.dialect.MySQLInnoDBDialect，但它仍然给出相同的异常(exception)。我将 spring 3.1.0 与 hibernate 3 和 mysql 5 一起使用。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;
}
我进行了很多搜索，但几乎无法解决可能出现的问题。因此，我们将不胜感激任何帮助。

首先，你的方言是错误的。对于 MySQL 5，您需要使用 org.hibernate.dialect.MySQL5Dialect。 MySQL 5 InnoDB 方言是 org.hibernate.dialect.MySQL5InnoDBDialect。
这个异常清楚地告诉你错误的原因:
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 'match this_ left outer join ref_country country2_ on this_.country1_id=country2_' at line 1
您的 Hibernate SQL:

匹配 是 reserved word in MySQL 5 .我的建议是将您的实体重命名为另一个名称。

作为我的Rails应用程序的一部分，我编写了一个小导入程序，它从我们的LDAP系统中吸取数据并将其塞入一个用户表中。不幸的是，与LDAP相关的代码在遍历我们的32K用户时泄漏了大量内存，我一直无法弄清楚如何解决这个问题。这个问题似乎在某种程度上与LDAP库有关，因为当我删除对LDAP内容的调用时，内存使用情况会很好地稳定下来。此外，不断增加的对象是Net::BER::BerIdentifiedString和Net::BER::BerIdentifiedArray，它们都是LDAP库的一部分。当我运行导入时，内存使用量最终达到超过1GB的峰值。如果问题存在，我需要找到一些方法来更正我的代

我注意到像bundler这样的项目在每个specfile中执行requirespec_helper我还注意到rspec使用选项--require，它允许您在引导rspec时要求一个文件。您还可以将其添加到.rspec文件中，因此只要您运行不带参数的rspec就会添加它。使用上述方法有什么缺点可以解释为什么像bundler这样的项目选择在每个规范文件中都需要spec_helper吗？ 最佳答案 我不在Bundler上工作，所以我不能直接谈论他们的做法。并非所有项目都checkin.rspec文件。原因是这个文件，通常按照当前的惯例，只
