springboot+mybatis 配置双数据源

文件放置的位置，对应的同一个数据库的dao要放在同一个包里

1.配置文件application.yml

spring:
  datasource:
    driverClassName: com.mysql.jdbc.Driver
    test1:
      #driver-class-name: com.mysql.jdbc.Driver
      jdbc-url: jdbc:mysql://xxxx:3306/tqsq? serverTimezone=UTC&useUnicode=true&characterEncoding=utf8&characterSetResults=utf8&useSSL=false&verifyServerCertificate=false&autoReconnct=true&autoReconnectForPools=true&allowMultiQueries=true
      username: 
      password: 
    test2:
      #driver-class-name: com.mysql.jdbc.Driver
      jdbc-url: jdbc:mysql://xxxxx:3306/jiameng?serverTimezone=UTC&useUnicode=true&characterEncoding=utf8&characterSetResults=utf8&useSSL=false&verifyServerCertificate=false&autoReconnct=true&autoReconnectForPools=true&allowMultiQueries=true
      username: 
      password: 

2.配置config—dataSource1文件

@Configuration
@MapperScan(basePackages = "com.zhy.dao.test1",sqlSessionFactoryRef = "db1SqlSessionFactory")
public class DataSource1Config {
    /**
     * 返回db1数据库的数据源
     * @return
     */
    @Bean(name = "db1DataSource")
    @ConfigurationProperties(prefix = "spring.datasource.test1")
    @Primary
    public DataSource testDataSource(){

        return DataSourceBuilder.create().build();
    }

    /**
     * 创建sqlsessionfactory  工厂会话
     * @param dataSource
     * @return
     */
    @Bean(name = "db1SqlSessionFactory")
    @Primary
    public SqlSessionFactoryBean testSqlSessionFactory(@Qualifier("db1DataSource") DataSource dataSource) throws Exception {
        SqlSessionFactoryBean bean  =new SqlSessionFactoryBean();
        bean.setDataSource(dataSource);
    //    bean.setMapperLocations(new Resource[]{new PathMatchingResourcePatternResolver().getResource("classpath:com.zhy.dao.test1.*.xml")});//路径
        Resource[] resources = new PathMatchingResourcePatternResolver()
                .getResources("classpath*:com/zhy/dao/test1/*Mapper.xml");

        bean.setMapperLocations(resources);
        return bean;

    }

    /**
     * 配置事务管理
     * @param dataSource
     * @return
     */
    @Bean(name = "db1TransactionManager")
    @Primary
    public DataSourceTransactionManager testTransactionManager(@Qualifier("db1DataSource")DataSource dataSource){
            return new DataSourceTransactionManager(dataSource);
    }

    /**
     * 返回数据库会话模板
     * @param sqlSessionFactory
     * @return
     */
    @Bean(name = "db1SqlSessionTemplate")
    @Primary
    public SqlSessionTemplate testSqlSessionTemplate(@Qualifier("db1SqlSessionFactory")SqlSessionFactory sqlSessionFactory){
            return new SqlSessionTemplate(sqlSessionFactory);
    }

}

3.配置config—dataSource2文件

@Configuration
@MapperScan(basePackages = "com.zhy.dao.test2",sqlSessionFactoryRef = "db2SqlSessionFactory")
public class DataSource2Config {

    @Bean(name = "db2DataSource")
    @ConfigurationProperties(prefix = "spring.datasource.test2")
    public DataSource testDataSource(){

        return DataSourceBuilder.create().build();
    }

    /**
     * 创建sqlsessionfactory
     * @param dataSource
     * @return
     */
    @Bean(name = "db2SqlSessionFactory")
    public SqlSessionFactoryBean testSqlSessionFactory(@Qualifier("db2DataSource") DataSource dataSource) throws Exception {
        SqlSessionFactoryBean bean  =new SqlSessionFactoryBean();
        bean.setDataSource(dataSource);
     //   bean.setMapperLocations(new Resource[]{new PathMatchingResourcePatternResolver().getResource("classpath:com.zhy.dao.test2.*.xml")});//路径
      //      return bean.getObject();
        Resource[] resources = new PathMatchingResourcePatternResolver()
                .getResources("classpath*:com/zhy/dao/test2/*Mapper.xml");

        bean.setMapperLocations(resources);
        return bean;

    }

    /**
     * 配置事务管理
     * @param dataSource
     * @return
     */
    @Bean(name = "db2TransactionManager")
    public DataSourceTransactionManager testTransactionManager(@Qualifier("db2DataSource")DataSource dataSource){
            return new DataSourceTransactionManager(dataSource);
    }

    @Bean(name = "db2SqlSessionTemplate")
    public SqlSessionTemplate testSqlSessionTemplate(@Qualifier("db2SqlSessionFactory")SqlSessionFactory sqlSessionFactory){
            return new SqlSessionTemplate(sqlSessionFactory);
    }

}
