在Hibernate中是否有可能用真实值而不是问号打印生成的SQL查询?
如果无法使用Hibernate API,您会建议如何使用实际值打印查询?

当前回答
下面是对我有用的,在log4j.file中设置下面的属性:
log4j.logger.org.hibernate.type.descriptor.sql.BasicBinder=TRACE
Hibernate属性设置:
hibernate.show_sql=true
其他回答
您需要配置如下:
# Hibernate logging options (INFO only shows startup messages)
log4j.logger.org.hibernate=INFO
# Log JDBC bind parameter runtime arguments
log4j.logger.org.hibernate.type=trace
对我来说,最简单的解决方案是实现一个常规的字符串替换,将参数输入替换为参数值(为了简单起见,将所有参数都视为字符串):
String debuggedSql = sql;
// then, for each named parameter
debuggedSql = debuggedSql.replaceAll(":"+key, "'"+value.toString()+"'");
// and finally
System.out.println(debuggedSql);
或者类似的位置参数(?)。
如果您想要记录运行就绪的SQL,请注意空值和特定的值类型(如date)。
打开org.hibernate.type记录器,查看实际参数是如何绑定到问号的。
在使用Wildfly (standalone.xml)进行开发时,添加以下记录器:
<logger category="org.hibernate.SQL">
<level name="DEBUG"/>
</logger>
<logger category="org.hibernate.type.descriptor.sql">
<level name="TRACE"/>
</logger>
你可以记录这个:net.sf.hibernate.hql.QueryTranslator
输出的例子:
