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"
    xmlns:p="http://www.springframework.org/schema/p"
    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/mvc 
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context.xsd">

    <!-- 配置spring MVC -->
    <!-- 1.开启springmvc注解模式 -->
    <mvc:annotation-driven>  
    <!-- 处理responseBody 里面日期类型 -->  
        <mvc:message-converters>  
            <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">  
                <property name="objectMapper">  
                    <bean class="com.fasterxml.jackson.databind.ObjectMapper">  
                        <property name="dateFormat">  
                            <bean class="java.text.SimpleDateFormat">

                            </bean>  
                        </property>  
                    </bean>  
                </property>  
            </bean>  
        </mvc:message-converters>  
    </mvc:annotation-driven>  
    
    <!-- 2.静态资源默认servlet配置 
    (1)加入对静态资源的处理：js/gif/png
    (2)允许使用"/"做整体映射    
    -->
    <mvc:resources mapping="/**" location="/static/" />
    <mvc:default-servlet-handler/>
	
	
    <!-- 3.定义视图解析器 -->
    <bean id="viewResolver" 
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 配置逻辑视图前后缀 -->
        <property name="prefix" value="/WEB-INF/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>
    
    <!-- 4.扫描web相关的bean -->
    <context:component-scan base-package="com.rms"/>
    <!-- 配置文件上传解析器 -->
	<bean id="multipartResolver"
		class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
		<!-- 上传的最大限制 -->

		<!-- 设置请求编码格式 -->	
		<property name="defaultEncoding" value="UTF-8"/>
		<!-- 上传文件的解析 -->

			<mvc:exclude-mapping path="/manage/resources/**"/>
			<bean class="com.rms.interceptor.ManageLoginInterceptor"/>
		</mvc:interceptor>
	</mvc:interceptors>
</beans>

2.spring-mybatis.xml

1.基于mapper.xml文件的配置

  此示例使用dbcp连接池。

<?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" />

	<!-- 配置数据源 -->
	<bean id="dataSource"
		class="org.apache.commons.dbcp2.BasicDataSource">
		<!-- 驱动类 -->
		<property name="driverClassName" value="${jdbc.driver}" />
		<!-- 连接地址 -->
		<property name="url" value="${jdbc.url}" />
		<!-- 用户名 -->
		<property name="username" value="${jdbc.username}" />
		<!-- 密码 -->
		<property name="password" value="${jdbc.password}" />

		<!-- 连接初始值，连接池启动时创建的连接数量的初始值，默认值为 0 -->
		<property name="initialSize"
			value="${pool.dbcp2.initialSize}" />
		<!-- 最小空间值，当空间的连接数少于阈值时，连接池就会去预申请一些连接，以免洪峰来时来不及申请，默认值为 0 -->
		<property name="minIdle" value="${pool.dbcp2.minIdle}" />
		<!-- 最大空间值，当经过一个高峰时间后，连接池可以慢慢将已经用不到的连接慢慢释放一部分，一直减少到 maxIdle 为止 ，0 时无限制，默认值为8 -->
		<property name="maxIdle" value="${pool.dbcp2.maxIdle}" />
		<!-- 连接池的最大值，同一时间可以从池分配的最多连接数量，0 时无限制，默认值为8 -->
		<property name="maxTotal" value="${pool.dbcp2.maxTotal}" />
		<!--是否自动提交事务，即单条 SQL 语句算是一个事务 -->
		<property name="defaultAutoCommit"
			value="${pool.dbcp2.defaultAutoCommit}" />
	</bean>


    <!-- MyBatis 构建 SqlSessionFactory 的实例配置文件 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 数据源 -->
        <property name="dataSource" ref="dataSource"/>
        <!--加载mybatis配置文件-->
        <property name="configLocation" value="classpath:mybatis/mybatis-config.xml"></property>
        <!-- Mapper 配置文件所在路径 -->
        <property name="mapperLocations" value="classpath:mybatis/mapper/*.xml"/>
        <!--配置包别名 -->
        <property name="typeAliasesPackage" value="${实体类所在包全限名}"/>
    </bean>

    

    <!-- MyBatis 自动查找指定包名下的Mapper类，如果找到对应的映射文件，将包下的 interface 动态定义为 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.基于mapper注解的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连接池-->
    <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>
