spring+mybatis多数据源的配置

解决方案：

多套sqlSessionFactory，针对不同的数据源

数据源

Xml代码  

<something-else-entirely>
    <proxool>
        <alias>peccancyalias>
        <driver-url>jdbc:oracle:thin:@172.16.60.46:1521:orcldriver-url>
        <driver-class>oracle.jdbc.driver.OracleDriverdriver-class>
        <driver-properties>
            <property name="user" value="oses"/>
            <property name="password" value="oses"/>
        driver-properties>
        ...
    proxool>
    <proxool>
        <alias>yhtepapalias>
        <driver-url>jdbc:oracle:thin:@172.16.60.46:1521:orcldriver-url>
        <driver-class>oracle.jdbc.driver.OracleDriverdriver-class>
        <driver-properties>
            <property name="user" value="pap"/>
            <property name="password" value="pap"/>
        driver-properties>
        ...
    proxool>
something-else-entirely>

 1.方法一

Xml代码  

<bean id="dataSource_peccancy" class="org.springframework.jdbc.datasource.DriverManagerDataSource" >
    <property name="driverClassName">
        <value>org.logicalcobwebs.proxool.ProxoolDrivervalue>
    property>
    <property name="url">
        <value>proxool.peccancyvalue>
    property>
bean>
<bean id="dataSource_pap" class="org.springframework.jdbc.datasource.DriverManagerDataSource" >
    <property name="driverClassName">
        <value>org.logicalcobwebs.proxool.ProxoolDrivervalue>
    property>
    <property name="url">
        <value>proxool.papvalue>
    property>
bean>

  

Xml代码  

<bean id="sqlSessionFactory_peccancy" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource_peccancy" />
    <property name="mapperLocations">
        <list>
            <value>classpath:net/yhte/common/query/mapper/PageData_Mapper.xmlvalue>
            <value>classpath*:net/yhte/web/peccancy/**/mapper/*Mapper.xmlvalue>
        list>
    property>
bean>
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="net.yhte.web.peccancy.**.dao" />
    <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory_peccancy">property>
bean>
<bean id="sqlSessionFactory_pap" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource_pap" />
    <property name="mapperLocations">
        <list>
            <value>classpath*:net/yhte/web/pap/**/mapper/*Mapper.xmlvalue>
            <value>classpath:net/yhte/common/query/mapper/PageData_Mapper.xmlvalue>
        list>
    property>
bean>
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="net.yhte.web.pap.**.dao" />
    <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory_pap">property>
bean>

 本方案需要根据数据源的不同对*Mapper.xml进行分包处理，便于配置，同一个包下的*Mapper.xml如果对应的数据源不同，则不方便使用通配符进行统一扫描配置，且sqlSessionFactory扫包的basePackage 也需要分包。

2.使用自定义注解来取代spring的repository设置到annotationClass中。这样每个mapper文件中注入相应的注解@PapRepository，@PeccancyRepository

 改成

  配置文件如下：

Xml代码  

<bean id="sqlSessionFactory_peccancy" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource_peccancy" />
        <property name="mapperLocations">
            <list>
                <value>classpath:net/yhte/common/query/mapper/PageData_Mapper.xmlvalue>
                <value>classpath*:net/yhte/web/**/mapper/*Mapper.xmlvalue>
            list>
        property>
    bean>
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="annotationClass" value="net.yhte.common.service.PeccancyRepository">property>
        <property name="basePackage" value="net.yhte.web.**.dao" />
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory_peccancy">property>
    bean>
    <bean id="sqlSessionFactory_pap" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource_pap" />
        <property name="mapperLocations">
            <list>
                <value>classpath:net/yhte/common/query/mapper/PageData_Mapper.xmlvalue>
                <value>classpath*:net/yhte/web/**/mapper/*Mapper.xmlvalue>
            list>
        property>
    bean>
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="annotationClass" value="net.yhte.common.service.PapRepository">property>
        <property name="basePackage" value="net.yhte.web.**.dao" />
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory_pap">property>
    bean>

 如上所配置使用pap的mapper文件就加上注解@PapRepository

Java代码  

public @interface PeccancyRepository {

}

public @interface PapRepository {

}

 

 

Java代码  

// 使用dataSource_pap 数据源
@PapRepository
public interface UserMapper {
    List find(UserQueryBean userQueryBean);
}
// 使用dataSource_peccancy 数据源
@PeccancyRepository
public interface ParameterMapper{

    List find(ParameterQueryBean queryBean);
}
