SSM框架整合基本操作
1.首先导入各种需要的配置包，在这里个人的习惯就是先导入mybatis相关包，然后通过编程软件集成一个spring3.0或者spring3.1进来并选择里面相应的包，这样就不需要我们自己去导入相应的spring包了。
2.新建spring-mybatis.xml文件以及spring-mvc.xml文件，分别配置如下：
spring-mybatis.xml配置文件
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans 3 xmlns="http://www.springframework.org/schema/beans" 4 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 5 xmlns:p="http://www.springframework.org/schema/p" 6 xmlns:context="http://www.springframework.org/schema/context" 7 xsi:schemaLocation="http://www.springframework.org/schema/beans 8 http://www.springframework.org/schema/beans/spring-beans-3.1.xsd 9 http://www.springframework.org/schema/context 10 http://www.springframework.org/schema/context/spring-context-3.1.xsd 11 "> 12 <!-- 采用注释的方式配置bean --> 13 <context:annotation-config /> 14 <!-- 配置要扫描的包 --> 15 <context:component-scan base-package="com.julong.testoracle" /> 16 17 <!-- 分解配置 jdbc.properites --> 18 <context:property-placeholder location="classpath:jdbc.properties" /> 19 <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> 20 <property name="driverClassName" value="${jdbc.driverClassName}" /> 21 <property name="url" value="${jdbc.url}" /> 22 <property name="username" value="${jdbc.username}" /> 23 <property name="password" value="${jdbc.password}" /> 24 <!-- 队列中的最小等待数 --> 25 <property name="minIdle" value="${jdbc.minIdle}"></property> 26 <!-- 队列中的最大等待数 --> 27 <property name="maxIdle" value="${jdbc.maxIdle}"></property> 28 <!-- 最长等待时间，单位毫秒 --> 29 <property name="maxWait" value="${jdbc.maxWait}"></property> 30 <!-- 最大活跃数 --> 31 <property name="maxActive" value="${jdbc.maxActive}"></property> 32 <property name="initialSize" value="${jdbc.initialSize}"></property> 33 </bean> 34 35 <!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 --> 36 <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> 37 <property name="dataSource" ref="dataSource" /> 38 <!-- 自动扫描mapping.xml文件 --> 39 <property name="mapperLocations" value="classpath:com/julong/testoracle/mapper/*.xml"></property> 40 </bean> 41 42 <!-- DAO接口所在包名，Spring会自动查找其下的类 --> 43 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> 44 <property name="basePackage" value="com.julong.testoracle.dao"> </property> 45 <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property> 46 </bean> 47 48 <!-- (事务管理)transaction manager, use JtaTransactionManager for global tx --> 49 <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> 50 <property name="dataSource" ref="dataSource" /> 51 </bean> 52 </beans>
spring-mvc.xml配置文件
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">
<!-- 配置需要用过mvc监听的文件 --> <context:component-scan base-package="com.julong.testoracle.controller" /> </beans>
3.配置相应的web.xml文件如下：
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 3 xmlns="http://java.sun.com/xml/ns/javaee" 4 xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 5 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 6 http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0"> 7 <display-name>oracle</display-name> 8 <!-- spring的监听器 --> 9 <listener> 10 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 11 </listener> 12 13 <!--全局范围内环境参数初始化，即初始化spring-mybatis.xml--> 14 <context-param> 15 <param-name>contextConfigLocation</param-name> <!--参数名称--> 16 <param-value>classpath:spring-mybatis.xml</param-value><!--参数取值--> 17 </context-param> 18 19 !--用来声明一个servlet的数据 --> 20 <servlet> 21 <servlet-name>springMVC</servlet-name><!--指定servlet的名称--> 22 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><!--指定servlet的类名称,这里配置了前端控制器--> 23 <init-param> 24 <param-name>contextConfigLocation</param-name><!--参数名称--> 25 <param-value>classpath:spring-mvc.xml</param-value><!--参数值--> 26 </init-param> 27 </servlet> 28 <servlet-mapping> 29 <servlet-name>springMVC</servlet-name> <!--指定servlet的名称--> 30 <url-pattern>*.mvc</url-pattern> <!--指定servlet所对应的URL--> 31 </servlet-mapping> 32 33 <!-- 编码过滤器 --> 34 <filter> 35 <filter-name>CharacterEncodingFilter</filter-name> 36 <filter-class> 37 org.springframework.web.filter.CharacterEncodingFilter 38 </filter-class> 39 <init-param> 40 <param-name>encoding</param-name> 41 <param-value>UTF-8</param-value> 42 </init-param> 43 </filter> 44 <filter-mapping> 45 <filter-name>CharacterEncodingFilter</filter-name> 46 <url-pattern>/*</url-pattern> 47 </filter-mapping> 48 </web-app>
4.指定数据库连接时需要引入的资源文件（因前面给其分解开来了）
#jdbc.driverClassName=com.mysql.jdbc.Driver jdbc.driverClassName=oracle.jdbc.OracleDriver #jdbc.url=jdbc:mysql://localhost:3306/operationLog jdbc.url=jdbc:oracle:thin:@127.0.0.1:1521:orcl #jdbc.url=jdbc:oracle:thin:@192.168.1.111:1521:orcl jdbc.username=oracle jdbc.password=oracle #jdbc.password=root jdbc.maxActive = 2 jdbc.maxIdle =5 jdbc.minIdle=1 jdbc.initialSize =3 jdbc.maxWait =3000
