（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

这里仅仅是一些常见的配置怎样具体的配置信息请查找：hibernate-distribution-3.3.1.GA---->project---->etc---->hibernate.properties文件！
