基于Spring+SpringMVC+Mybatis的分布式敏捷开发系统架构

以下是一个简化的Spring+SpringMVC+MyBatis分布式敏捷开发系统架构示例：

1. 数据库配置文件 database.properties:

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/myapp
jdbc.username=root
jdbc.password=secret

2. Spring配置文件 applicationContext.xml:

<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">
 
    <import resource="database.properties" />
 
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="${jdbc.driver}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>
 
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>
 
    <!-- 扫描Mapper接口并注册 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.example.mapper"/>
    </bean>
 
</beans>

3. MyBatis配置文件 mybatis-config.xml:

<configuration>
    <typeAliases>
        <package name="com.example.model"/>
    </typeAliases>
    <mappers>
        <package name="com.example.mapper"/>
    </mappers>
</configuration>

4. Spring MVC配置文件 dispatcher-servlet.xml:

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       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
                           http://www.springframework.org/schema/context
