spring boot多数据源配置

1.spring.xml里，注入bean

<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"
        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">
    <import resource="spring-dao-sipserver.xml" />
</beans>

2.spring-dao-sipserver.xml 里配置数据源，其内部的Dao类路径结构，对应起来即可

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

    <bean
            id="abstractDataSource-sipserver"
            abstract="true"
            class="com.alibaba.druid.pool.DruidDataSource"
            p:maxActive="9"
            p:maxWait="10000"
            p:proxyFilters-ref="druidFilters" />

    <bean
        class="org.mybatis.spring.mapper.MapperScannerConfigurer"
        p:basePackage="com.xxx.dao.api.sipserver"
        p:sqlSessionFactoryBeanName="sqlSessionFactory-sipserver" />

    <bean
        id="sqlSessionFactory-sipserver"
        class="org.mybatis.spring.SqlSessionFactoryBean"
        p:mapperLocations="classpath*:mybatis-mapper-sipserver/*.xml"
        p:dataSource-ref="dataSource-sipserver"
        p:plugins-ref="mybatisPlugins" />

    <bean
        id="dataSource-sipserver"
        parent="abstractDataSource-sipserver"
        p:url="jdbc:mysql://127.0.0.1:3306/sipserver"
        p:username="admin"
        p:password="admin" />

    <!-- 事务注解驱动 -->
    <tx:annotation-driven transaction-manager="transactionManager-sipserver" />

    <bean
        id="transactionManager-sipserver"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager"
        p:dataSource-ref="dataSource-sipserver" />
</beans>
