maven数据库配置

1. 如何在maven pom里面配置springmvc hibernate连接oracle数据库

一般创建出来的项目，只有src/main/resources，然后我们加上其他的三项(必须是新建Source
Folder！
src/main/java;
src/test/resources;
src/test/java)，有时候会提示你该文件夹已经存在，我们稍改一下名，等创建完了后再用F2改回正确的就OK了(例如src/main/java创建失败，我们把java改为javas，最后再改为java即可。)

2. 如何配置pom.xml用maven打包java工程

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

4. ssm框架中怎么配置数据库连接池

Druid配置
1.下载jar包：http://repo1.maven.org/maven2/com/alibaba/druid/
2.编写数据库连接的资源文件：dbconfig.properties
url:jdbc:mysql://localhost:3306/flm?useUnicode=true&characterEncoding=utf8
driverClassName:com.mysql.jdbc.Driver
username:root
password:root

#------------------------------------------------------------------------------------------
#配置扩展插件 监控统计用filters:stat 日志用filters:log4j 防御sql注入用filters:wall
filters:stat

#最大连接池数量 初始化建立物理连接的个数 获取连接时最长的等待时间 最小连接池数量 maxIdle已经弃用
maxActive:20
initialSize:1
maxWait:60000
minIdle:10
maxIdle:15

#有两个含义 1.Destroy 线程会检测连接的时间 2.testWhileIdle的判断依据
timeBetweenEvictionRunsMillis:60000

#Destory线程中如果检测到当前连接的最后活跃时间和当前时间的差值大于minEvictableIdleTimeMillis，则关闭当前连接
minEvictableIdleTimeMillis:300000

#用来检测连接是否的sql，要求是一个查询语句。在mysql中通常设置为SELECT 'X'
validationQuery:SELECT 'x'

#申请连接的时候检测，如果空闲时间大于timeBetweenEvictionRunsMillis，执行validationQuery连接是否有效
testWhileIdle:true

#申请连接时执行validationQuery检测连接是否有效 这个配置会降低性能
testOnBorrow:false

#归还连接时执行validationQuery检测连接是否有效 这个配置会降低性能
testOnReturn:false

#要启用PSCache，必须配置大于0，当大于0时，poolPreparedStatements自动触发修改为true
maxOpenPreparedStatements:20

#对于建立连接超过removeAbandonedTimeout的连接强制关闭
removeAbandoned:true

#指定连接建立多长就被强制关闭
removeAbandonedTimeout:1800

#指定发生removeabandoned时，是否记录当前线程的堆栈信息到日志中
logAbandoned:true

3.在Spring配置文件ApplicationContext.xml中加载资源文件进来
<!--PropertyPlaceholderConfigurer是个bean工厂后置处理器的实现，也就是 BeanFactoryPostProcessor接口的一个实现。PropertyPlaceholderConfigurer可以将上下文（配置文 件）中的属性值放在另一个单独的标准java Properties文件中去。-->
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>/WEB-INF/classes/dbconfig.properties</value> <!--dbconfig.properties 数据库连接信息-->
</list>
</property>
</bean> 1234567812345678

4.在Spring配置文件ApplicationContext.xml中配置阿里数据连接池Druid

<!-- 阿里 druid数据库连接池 -->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" destroy-method="close">
<!-- 数据库基本信息配置 -->
<property name="url" value="${url}" />
<property name="username" value="${username}" />
<property name="password" value="${password}" />
<property name="driverClassName" value="${driverClassName}" />
<property name="filters" value="${filters}" />
<!-- 最大并发连接数 -->
<property name="maxActive" value="${maxActive}" />
<!-- 初始化连接数量 -->
<property name="initialSize" value="${initialSize}" />
<!-- 配置获取连接等待超时的时间 -->
<property name="maxWait" value="${maxWait}" />
<!-- 最小空闲连接数 -->
<property name="minIdle" value="${minIdle}" />
<!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 -->
<property name="timeBetweenEvictionRunsMillis" value="${timeBetweenEvictionRunsMillis}" />
<!-- 配置一个连接在池中最小生存的时间，单位是毫秒 -->
<property name="minEvictableIdleTimeMillis" value="${minEvictableIdleTimeMillis}" />
<property name="validationQuery" value="${validationQuery}" />
<property name="testWhileIdle" value="${testWhileIdle}" />
<property name="testOnBorrow" value="${testOnBorrow}" />
<property name="testOnReturn" value="${testOnReturn}" />
<property name="maxOpenPreparedStatements" value="${maxOpenPreparedStatements}" />
<!-- 打开removeAbandoned功能 -->
<property name="removeAbandoned" value="${removeAbandoned}" />
<!-- 1800秒，也就是30分钟 -->
<property name="removeAbandonedTimeout" value="${removeAbandonedTimeout}" />
<!-- 关闭abanded连接时输出错误日志 -->
<property name="logAbandoned" value="${logAbandoned}" />
</bean>

5. Intellij IDEA配置数据库连接信息的在哪里呢

就在maven上边
