使用maven實現ssm整合配置檔案
阿新 • • 發佈：2019-01-07
1.引入專案依賴的jar包（pop.xml）
包含：spring、springmvc、mybatics、Mybatis整和Spring的適配包、資料庫連線池、mysql驅動、單元測試
(注意版本問題！！！)
參考網址：https://mvnrepository.com/ (maven repository)

此處一定要注意版本，以及依賴jar包的問題，不然很容易出問題（比如c3p0，除了匯入c3p0的jar包外，還要匯入一個依賴jar包！！！！！）
2.配置mybatis（mybatis-config.xml）
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <settings> <setting name="mapUnderscoreToCamelCase" value="true"/> </settings> <typeAliases> <package name="com.atguigu.crud.bean"/> </typeAliases> </configuration>
3.配置spring
3.1配置dao（applicationContext-dao.xml）
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd"> <!-- Spring的配置檔案，這裡主要配置和業務邏輯有關的 --> <!--=================== 資料來源，事務控制，xxx ================--> <context:property-placeholder location="classpath:dbconfig.properties" /> <bean id="pooledDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property> <property name="driverClass" value="${jdbc.driverClass}"></property> <property name="user" value="${jdbc.user}"></property> <property name="password" value="${jdbc.password}"></property> </bean> <!--================== 配置和MyBatis的整合=============== --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 指定mybatis全域性配置檔案的位置 --> <property name="configLocation" value="classpath:mybatis-config.xml"></property> <property name="dataSource" ref="pooledDataSource"></property> <!-- 指定mybatis，mapper檔案的位置 --> <property name="mapperLocations" value="classpath:mapper/*.xml"></property> </bean> <!-- 配置掃描器，將mybatis介面的實現加入到ioc容器中 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <!--掃描所有dao介面的實現，加入到ioc容器中 --> <property name="basePackage" value="com.atguigu.crud.dao"></property> </bean> <!-- 配置一個可以執行批量的sqlSession --> <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate"> <constructor-arg name="sqlSessionFactory" ref="sqlSessionFactory"></constructor-arg> <constructor-arg name="executorType" value="BATCH"></constructor-arg> </bean> <!--============================================= --> </beans>
資料庫配置檔案（dbconfig.properties）
jdbc.jdbcUrl=jdbc:mysql://localhost:3306/ssm_crud?useUnicode=true&characterEncoding=UTF-8&useSSL=false
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.user=root
jdbc.password=1022zhang3.2配置service（applicationContext-service.xml）
<?xml version="1.0" encoding="UTF-8"?>

</context:component-scan>
</beans>3.3配置事務（applicationContext-transaction.xml）

4.配置springmvc（dispatcherServlet.xml）

<!--只掃描控制器。 -->
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<!--配置檢視解析器，方便頁面返回 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
<!--兩個標準配置 -->
<!-- 將springmvc不能處理的請求交給tomcat -->
<mvc:default-servlet-handler/>
<!-- 能支援springmvc更高階的一些功能，JSR303校驗，快捷的ajax...對映動態請求 -->
<!-- 處理器對映器處理器介面卡 -->
<mvc:annotation-driven/>
</beans>
