springboot+mybatis多数据源

1. pom文件配置
   <dependency>
       <groupId>org.mybatis.spring.boot</groupId>
       <artifactId>mybatis-spring-boot-starter</artifactId>
       <version>1.3.2</version>
   </dependency>      

2. yml文件配置

   spring:

     datasource:

       test1:

         jdbcUrl: jdbc:mysql://localhost:3306/multipledatasource1?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC&useSSL=false

         username: root

         password: root

         driverClassName: com.mysql.cj.jdbc.Driver

       test2:

         jdbcUrl: jdbc:mysql://localhost:3306/multipledatasource2?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC&useSSL=false

         username: root

         password: root

         driverClassName: com.mysql.cj.jdbc.Driver

3. 数据源配置类1

   //表示这个类为一个配置类

   @Configuration

   // 配置mybatis的接口类放的地方

   @MapperScan(basePackages = "com.xx.mapper.test1", sqlSessionFactoryRef = "test1SqlSessionFactory")

   public class DataSourceConfig1 {

       // 将这个对象放入Spring容器中

       @Bean(name = "test1DataSource")

       // 表示这个数据源是默认数据源

       @Primary

       // 读取application.properties中的配置参数映射成为一个对象

       // prefix表示参数的前缀

       @ConfigurationProperties(prefix = "spring.datasource.test1")

       public DataSource getDateSource1() {

           DataSource ds = DataSourceBuilder.create().build();

           return ds;

       }

       @Bean(name = "test1SqlSessionFactory")

       // 表示这个数据源是默认数据源

       @Primary

       // @Qualifier表示查找Spring容器中名字为test1DataSource的对象

       public SqlSessionFactory test1SqlSessionFactory(@Qualifier("test1DataSource") DataSource datasource)

               throws Exception {

           SqlSessionFactoryBean bean = new SqlSessionFactoryBean();

           bean.setDataSource(datasource);

           bean.setConfigLocation(new PathMatchingResourcePatternResolver().getResource("classpath:config/mybatis.cfg.xml"));

           bean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath*:com/xx/mapper

           bean.setConfigLocation(new PathMatchingResourcePatternResolver().getResource("classpath:config/mybatis.cfg.xml"));

           bean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath*:com/xx/mapper/*.xml"));

           return bean.getObject();

       }

       @Bean(name = "casTransactionManager")

       public DataSourceTransactionManager testTransactionManager(@Qualifier("test2DataSource") DataSource dataSource) {

           return new DataSourceTransactionManager(dataSource);

       }

       @Bean("test2SqlSessionTemplate")

       public SqlSessionTemplate test2sqlsessiontemplate(

               @Qualifier("test2SqlSessionFactory") SqlSessionFactory sessionfactory) {

           return new SqlSessionTemplate(sessionfactory);

       }

   }

4. 取消主入口类中的@

   MapperScan
