hibernate.cfg.xml文件的配置模板和不同数据库的配置参数

（1）hibernate.cfg.xml文件的配置模板

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

（3）C3P0 连接池

###########################
### C3P0 Connection Pool###
###########################

#hibernate.c3p0.max_size 2
#hibernate.c3p0.min_size 2
#hibernate.c3p0.timeout 5000
#hibernate.c3p0.max_statements 100

（4）Proxool 连接池

##############################
### Proxool Connection Pool###
##############################

## Properties for external configuration of Proxool

hibernate.proxool.pool_alias pool1

## Only need one of the following

#hibernate.proxool.existing_pool true
#hibernate.proxool.xml proxool.xml
#hibernate.proxool.properties proxool.properties

（5）JDBC Settings

#####################
### JDBC Settings ###
#####################

## specify a JDBC isolation level

#hibernate.connection.isolation 4
## enable JDBC autocommit (not recommended!)
#hibernate.connection.autocommit true
## set the JDBC fetch size
#hibernate.jdbc.fetch_size 25
## set the maximum JDBC 2 batch size (a nonzero value enables batching)
#hibernate.jdbc.batch_size 5
#hibernate.jdbc.batch_size 0
## enable batch updates even for versioned data
hibernate.jdbc.batch_versioned_data true
## enable use of JDBC 2 scrollable ResultSets (specifying a Dialect will cause Hibernate to use a sensible default)
#hibernate.jdbc.use_scrollable_resultset true
## use streams when writing binary types to / from JDBC
hibernate.jdbc.use_streams_for_binary true
## use JDBC 3 PreparedStatement.getGeneratedKeys() to get the identifier of an inserted row
#hibernate.jdbc.use_get_generated_keys false
## choose a custom JDBC batcher
# hibernate.jdbc.factory_class
## enable JDBC result set column alias caching
## (minor performance enhancement for broken JDBC drivers)
# hibernate.jdbc.wrap_result_sets
## choose a custom SQL exception converter
#hibernate.jdbc.sql_exception_converter

（6）Second-level Cache（二级缓存）

##########################
### Second-level Cache ###
##########################
## optimize chache for minimal "puts" instead of minimal "gets" (good for clustered cache)
#hibernate.cache.use_minimal_puts true
## set a prefix for cache region names
hibernate.cache.region_prefix hibernate.test
## disable the second-level cache
#hibernate.cache.use_second_level_cache false
## enable the query cache
#hibernate.cache.use_query_cache true
## store the second-level cache entries in a more human-friendly format
#hibernate.cache.use_structured_entries true
## choose a cache implementation
#hibernate.cache.provider_class org.hibernate.cache.EhCacheProvider
#hibernate.cache.provider_class org.hibernate.cache.EmptyCacheProvider
hibernate.cache.provider_class org.hibernate.cache.HashtableCacheProvider
#hibernate.cache.provider_class org.hibernate.cache.TreeCacheProvider
#hibernate.cache.provider_class org.hibernate.cache.OSCacheProvider
#hibernate.cache.provider_class org.hibernate.cache.SwarmCacheProvider
## choose a custom query cache implementation
#hibernate.cache.query_cache_factory

这里只是一些常见的配置 如何详细的配置信息请 查找：hibernate-distribution-3.3.1.GA---->project---->etc---->hibernate.properties文件！
