Log4j - org.hibernate.type doesn't work!
提问by Eran Medan
This is my logger configuration:
这是我的记录器配置：
log4j.logger.org.hibernate.SQL=TRACE, stdout
log4j.logger.org.hibernate.type=TRACE, stdout
but I don't see type bingings
但我没有看到类型绑定
So I tried this
所以我试过这个
log4j.logger.org.hibernate=TRACE, stdout
to see if I missed something (this shows all hibernate loggers)
and I found out that the org.hibernate.engine.QueryParameterslogger also shows parameter bindings (still no sign of org.hibernate.type logger binding messages)
看看我是否遗漏了什么（这显示了所有休眠记录器），我发现org.hibernate.engine.QueryParameters记录器还显示了参数绑定（仍然没有 org.hibernate.type 记录器绑定消息的迹象）
So then I tried
然后我尝试了
log4j.logger.org.hibernate.SQL=TRACE, stdout
log4j.logger.org.hibernate.type=TRACE, stdout
log4j.logger.org.hibernate.engine.QueryParameters=TRACE, stdout
but it shows me only logs from the org.hibernate.SQL logger!
但它只显示来自 org.hibernate.SQL 记录器的日志！
We use Hibernate 3.2.6.ga with classic query translator
我们使用 Hibernate 3.2.6.ga 和经典查询翻译器
Any clues?
有什么线索吗？

### Hibernate logging configuration ###
### Log everything (a lot of information, but very useful for troubleshooting) ###
#log4j.logger.org.hibernate=info
### Log HQL and SQL ASTs during query parsing ###
log4j.logger.org.hibernate.hql.ast.AST=DEBUG, SQL_APPENDER
log4j.additivity.org.hibernate.hql.ast.AST=false
### log just the SQL
log4j.logger.org.hibernate.SQL=DEBUG, SQL_APPENDER
log4j.additivity.org.hibernate.SQL=false
### log JDBC bind parameters. Very userfull, when debug parameterized queries ###
log4j.logger.org.hibernate.type=TRACE, SQL_APPENDER
log4j.additivity.org.hibernate.type=false
### log schema export/update ###
#log4j.logger.org.hibernate.tool.hbm2ddl=info
### log HQL parse trees
#log4j.logger.org.hibernate.hql=debug
### log cache activity ###
#log4j.logger.org.hibernate.cache=info
### log transaction activity
#log4j.logger.org.hibernate.transaction=debug
### Log all JDBC resource acquisition
#log4j.logger.org.hibernate.jdbc=debug
### enable the following line if you want to track down connection ###
### leakages when using DriverManagerConnectionProvider ###
#log4j.logger.org.hibernate.connection.DriverManagerConnectionProvider=trace
log4j.appender.SQL_APPENDER=org.apache.log4j.RollingFileAppender
log4j.appender.SQL_APPENDER.File=c\:/EC_sql.log
log4j.appender.SQL_APPENDER.MaxFileSize=1000KB
log4j.appender.SQL_APPENDER.MaxBackupIndex=62
log4j.appender.SQL_APPENDER.layout=org.apache.log4j.PatternLayout
log4j.appender.SQL_APPENDER.layout.ConversionPattern=[%d] %5p [%t] (%F:%L) - %m%n
you can comment or uncomment several options
您可以评论或取消评论多个选项
Attention: your webapp will be a lot slower when you use this. so only use it for debugging
注意：当你使用它时，你的 webapp 会慢很多。所以只用于调试

I faced the same problem with hibernate 3.5.5 and I found out that tracing is enabled by static field in org.hibernate.type.NullableType in the following way:
我在 hibernate 3.5.5 中遇到了同样的问题，我发现跟踪是由 org.hibernate.type.NullableType 中的静态字段通过以下方式启用的：
private static final boolean IS_VALUE_TRACING_ENABLED = LoggerFactory.getLogger( StringHelper.qualifier( Type.class.getName() ) ).isTraceEnabled();
So I set in log configuration log level TRACE for org.hibernate.type.Type and restarted a server.
因此，我为 org.hibernate.type.Type 设置了日志配置日志级别 TRACE 并重新启动了服务器。
<logger name="org.hibernate.type.Type" level="TRACE">
<appender-ref ref="myAppender"/>
</logger>
