SSM配置文件示例

1.spring-web.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"

        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context.xsd">

    <!-- 配置spring MVC -->
    <!-- 1.開啓springmvc註解模式 -->
    <mvc:annotation-driven>  
    <!-- 處理responseBody 裏面日期類型 -->  
        <mvc:message-converters>  
            <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">  
                <property name="objectMapper">  
                    <bean class="com.fasterxml.jackson.databind.ObjectMapper">  
                        <property name="dateFormat">

                        </property>  
                    </bean>

    <!-- 2.靜態資源默認servlet配置

    <mvc:resources mapping="/**" location="/static/" />
    <mvc:default-servlet-handler/>
	
	
    <!-- 3.定義視圖解析器 -->
    <bean id="viewResolver" 
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 配置邏輯視圖前後綴 -->

		</mvc:interceptor>
	</mvc:interceptors>
</beans>

2.spring-mybatis.xml

1.基於mapper.xml文件的配置

  此示例使用dbcp連接池。

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

    <!-- 引入 JDBC 配置文件 -->
	<context:property-placeholder
		location="classpath:properties/jdbc.properties"
		ignore-unresolvable="true" />

	<!-- 配置數據源 -->
	<bean id="dataSource"
		class="org.apache.commons.dbcp2.BasicDataSource">
		<!-- 驅動類 -->
		<property name="driverClassName" value="${jdbc.driver}" />
		<!-- 連接地址 -->
		<property name="url" value="${jdbc.url}" />
		<!-- 用戶名 -->
		<property name="username" value="${jdbc.username}" />
		<!-- 密碼 -->
		<property name="password" value="${jdbc.password}" />

		<!-- 連接初始值，連接池啓動時創建的連接數量的初始值，默認值爲 0 -->
		<property name="initialSize"
			value="${pool.dbcp2.initialSize}" />
		<!-- 最小空間值，當空間的連接數少於閾值時，連接池就會去預申請一些連接，以免洪峯來時來不及申請，默認值爲 0 -->
		<property name="minIdle" value="${pool.dbcp2.minIdle}" />
		<!-- 最大空間值，當經過一個高峯時間後，連接池可以慢慢將已經用不到的連接慢慢釋放一部分，一直減少到 maxIdle 爲止 ，0 時無限制，默認值爲8 -->
		<property name="maxIdle" value="${pool.dbcp2.maxIdle}" />
		<!-- 連接池的最大值，同一時間可以從池分配的最多連接數量，0 時無限制，默認值爲8 -->
		<property name="maxTotal" value="${pool.dbcp2.maxTotal}" />
		<!--是否自動提交事務，即單條 SQL 語句算是一個事務 -->
		<property name="defaultAutoCommit"
			value="${pool.dbcp2.defaultAutoCommit}" />
	</bean>


    <!-- MyBatis 構建 SqlSessionFactory 的實例配置文件 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 數據源 -->
        <property name="dataSource" ref="dataSource"/>
        <!--加載mybatis配置文件-->
        <property name="configLocation" value="classpath:mybatis/mybatis-config.xml"></property>
        <!-- Mapper 配置文件所在路徑 -->
        <property name="mapperLocations" value="classpath:mybatis/mapper/*.xml"/>
        <!--配置包別名 -->
        <property name="typeAliasesPackage" value="${實體類所在包全限名}"/>
    </bean>

    

    <!-- MyBatis 自動查找指定包名下的Mapper類，如果找到對應的映射文件，將包下的 interface 動態定義爲 Spring Bean -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="${mapper接口所在包全限名}"/>
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
    </bean>

</beans>

 jdbc.properties文件示例如下:

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/rms?tinyInt1isBit=false&useUnicode=true&characterEncoding=utf-8&autoReconnect=true&allowMultiQueries=true&useSSL=false
jdbc.username=root
jdbc.password=123456
pool.dbcp2.initialSize=3
pool.dbcp2.minIdle=3
pool.dbcp2.maxIdle=5
pool.dbcp2.maxTotal=15
pool.dbcp2.defaultAutoCommit=false

2.基於mapper註解的Spring整合Mybatis配置

<?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:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="
       http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
       http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
">


    <!--配置Druid連接池-->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
        <property name="url" value="jdbc:mysql://localhost:3306/demo?serverTimezone=UTC"></property>
        <property name="username" value="root"></property>
        <property name="password" value="123456"></property>
        <property name="initialSize" value="3"></property>
        <property name="maxActive" value="5"></property>
    </bean>

    <!--Spring整合Mybatis-->
    <bean class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
    </bean>

    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.hd.dao"></property>
    </bean>
</beans>
