2024-05-24 03:32

本文主要是介绍hibernate.cfg.xml文件的配置模板和不同数据库的配置参数,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!


(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"><!-- hibernate的核心配置文件 -->
<hibernate-configuration><session-factory><!--配置使用的mysql  --><property name="connection.driver_class">com.mysql.jdbc.Driver</property><property name="connection.username">root</property><property name="connection.password">root</property><property name="connection.url">jdbc:mysql:/127.0.0.1:3306/hibernatetest</property><!-- 配置dialect方言,明确告诉hibernate连接的是哪种数据库 --><property name="dialect">org.hibernate.dialect.MySQLDialect</property><!-- 显示出对应sql语句 --><property name="show_sql">true</property><!--让hibernate帮我们创建 一张表 --><property name="hbm2ddl.auto">update</property><pre code_snippet_id="479047" snippet_file_name="blog_20141003_1_1404018" name="code" class="html"><span style="white-space:pre">		</span><!-- 指定对象映射文件 --><mapping resource="com/lc/domain/Employee.hbm.xml" />
</session-factory></hibernate-configuration>
 

(2)上边知识介绍了关于Oracle的配置方式 但是对于其他的很多数据库配置的url driver等等没有相关的配置;

下边就是关于目前主流数据库配置模板的详细信息:

#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

#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!

poj3468(线段树成段更新模板题)

题意:包括两个操作:1、将[a.b]上的数字加上v;2、查询区间[a,b]上的和 下面的介绍是下解题思路: 首先介绍  lazy-tag思想:用一个变量记录每一个线段树节点的变化值,当这部分线段的一致性被破坏我们就将这个变化值传递给子区间,大大增加了线段树的效率。 比如现在需要对[a,b]区间值进行加c操作,那么就从根节点[1,n]开始调用update函数进行操作,如果刚好执行到一个子节点,
