一，从web.xml文件开始，
加载spring的配置文件
<!-- 加载配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:/spring/applicationContext.xml</param-value>
</context-param>
<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:/spring/applicationContext.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
配置监听器
<!-- 配置监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/method/*</url-pattern>
</servlet-mapping>
配置拦截器
<!-- 配置拦截器 -->
<filter>
<filter-name>characterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>characterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<filter>
<filter-name>HiddenHttpMethodFilter</filter-name>
<filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>HiddenHttpMethodFilter</filter-name>
<servlet-name>spring</servlet-name>
</filter-mapping>
写配置文件时，加载对应的jar包。
第二步，开始着手写spring的配置文件
自动扫描以及注解配置
<!-- 自动扫描 -->
<context:component-scan base-package="com.zc" />
<context:annotation-config />
<!-- 引入jdbc配置文件 -->
<context:property-placeholder location="classpath:jdbc.properties" ignore-unresolvable="true"/>
<!--创建jdbc数据源 -->
<bean id="parentDataSource" class="org.apache.commons.dbcp.BasicDataSource" abstract="true" destroy-method="close">
<property name="driverClassName" value="${jdbc.driverClassName}"/>
<property name="maxActive" value="1000" />
<property name="maxWait" value="1000" />
<property name="poolPreparedStatements" value="true" />
<property name="defaultAutoCommit" value="true" />
</bean>
<!-- 数据库 -->
<bean id="dataSource" parent="parentDataSource">
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
</bean>
配置事物
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
事物拦截方法
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="find*" propagation="SUPPORTS" read-only="true"/>
<tx:method name="get*" propagation="SUPPORTS" read-only="true"/>
<tx:method name="add*" propagation="REQUIRED"/>
<tx:method name="save*" propagation="REQUIRED"/>
<tx:method name="del*" propagation="REQUIRED"/>
<tx:method name="update*" propagation="REQUIRED"/>
<tx:method name="*" propagation="SUPPORTS" read-only="true"/>
</tx:attributes>
</tx:advice>
<!-- 配置哪些类的方法需要进行事务管理 -->
<aop:config>
<aop:pointcut id="allManagerMethod" expression="execution(* com.zc.servive.*.*(..))"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="allManagerMethod"/>
</aop:config>
<!-- 创建SqlSessionFactory，同时指定数据源 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation" value="classpath:/mybatis/sqlmap-config.xml" />
<!-- <property name="mapperLocations" value="classpath:/mybatis/mapper/*.xml" />-->
</bean>
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.zc.dao" />
</bean>
到此差不多了，框架基本没问题了，注意是jar一定要完全，要兼容 |
