我之所以写一个快速搭建的demo，主要想做一些容器的demo，所以为了方便大家，所以一切从简，简单的3层架构
先用mysql的ddl，后期不上oracle的ddl

预先准备：用插件自动生成自动生成DAO层，链接在（后期补上）
第一步：创建maven工程，导入依赖包，目前我的工程暂时叫MyArtifact

第二步：
创建3个资源文件（最简化的）
mybatis-config.xml （一些mybatis 的设置，和插件，例:pagehelper）
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "WEB-INF/dtd/mybatis-3-config.dtd"> <configuration> <!-- 分页插件 --> <plugins> <plugin interceptor="com.github.pagehelper.PageInterceptor"> <property name="helperDialect" value="oracle" /> <property name="offsetAsPageNum" value="true" /> <property name="rowBoundsWithCount" value="true" /> <property name="pageSizeZero" value="true" /> <property name="reasonable" value="true" /> <property name="params" value="pageNum=start;pageSize=limit;pageSizeZero=zero;reasonable=heli;count=contsql" /> </plugin> </plugins> </configuration>
第二个配置文件 applicationContext-*.xml(或者取其他名字)
作用：1>.数据源（两个例子）
<!-- 数据库连接池 :dataSource --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close"> <property name="driverClass" value="com.mysql.jdbc.Driver" /> <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/play?useUnicode=true&characterEncoding=UTF-8" /> <property name="user" value="root" /> <property name="password" value="root" /> <property name="minPoolSize" value="1" /> <property name="maxPoolSize" value="20" /> <property name="maxIdleTime" value="1800" /> <property name="acquireIncrement" value="2" /> <property name="maxStatements" value="0" /> <property name="initialPoolSize" value="2" /> <property name="idleConnectionTestPeriod" value="1800" /> <property name="acquireRetryAttempts" value="30" /> <property name="breakAfterAcquireFailure" value="true" /> <property name="testConnectionOnCheckout" value="false" /> </bean>
数据源demo2
<bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close"> <!-- 必须的配置 --> <property name="driverClassName" value="oracle.jdbc.OracleDriver" /> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> <property name="defaultAutoCommit" value="false" /> <!-- 可选配置 --> <!-- 连接池启动时创建的初始化连接数量（默认值为0） --> <property name="initialSize" value="${jdbc.initialSize}" /> <!-- 连接池中最大的空闲的连接数，超过的空闲连接将被释放，如果设置为负数表示不限制（默认为8个，maxIdle不能设置太小， 因为假如在高负载的情况下，连接的打开时间比关闭的时间快，会引起连接池中idle的个数 上升超过maxIdle，而造成频繁的连接销毁和创建，类似于jvm参数中的Xmx设置) --> <property name="maxIdle" value="${jdbc.maxIdle}" /> <!-- 连接池中最小的空闲的连接数，低于这个数量会被创建新的连接（默认为0，调整为5，该参数越接近maxIdle，性能越好， 因为连接的创建和销毁，都是需要消耗资源的； 但是不能太大，因为在机器很空闲的时候，也会创建低于minidle个数的连接，类似于jvm参数中的Xmn设置） --> <property name="minIdle" value="${jdbc.minIdle}" /> <!-- 并发连接的最大数。设置为0则无限制 --> <property name="maxTotal" value="${jdbc.maxTotal}" /> <!-- 等待连接的最大连接的时间,以毫秒计 --> <property name="maxWaitMillis" value="${jdbc.maxWaitMillis}" /> <!--SQL查询,用来验证从连接池取出的连接,在将连接返回给调用者之前. --> <property name="validationQuery" value="select sysdate from dual" /> <!--指明是否在从池中取出连接前进行检验,如果检验失败,则从池中去除连接并尝试取出另一个 --> <property name="testOnBorrow" value="true" /> </bean>
2>. 数据库配置SqlSessionFactoryBean(主要是：扫描mapper，定义事物管理)
<!-- 数据库配置SqlSessionFactoryBean --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="configLocation" value="classpath:mybatis-config.xml" /> </bean> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.howbuy.otc.dao.mapper" /> </bean> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean>
