数据源二配置：

//三、设置扫描器
@MapperScan(basePackages = "com.alibaba.gh.web.speech.mapper", sqlSessionFactoryRef = "sqlSessionFactory2")

public class TddlAutoConfiguration2 {

    @Autowired
    private TddlProperties properties;

    //一、创建数据源
    @Bean(name = "dataSource2")
    public DataSource dataSource2() throws TddlException {
        TDataSource dataSource = new TDataSource();
        dataSource.setAppName(properties.getAppName());
        dataSource.setSharding(properties.getSharding());
        dataSource.setDynamicRule(properties.getDynamicRule());
        dataSource.init();

        return dataSource;
    }

    //二、创建SqlSessionFactory
    @Bean(name = "sqlSessionFactory2")
    public SqlSessionFactory sqlSessionFactoryBean1() throws Exception {
        SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();

        sqlSessionFactoryBean.setDataSource(dataSource2());
        sqlSessionFactoryBean.setMapperLocations(resolveMapperLocations(new String[] { "classpath:mapper2/*.xml" }));

        return sqlSessionFactoryBean.getObject();
    }

    // 四、创建事务管理器
    @Bean(name = "txManager2")
    public PlatformTransactionManager txManager1(@Qualifier("dataSource2") DataSource dataSource) {

        System.out.println("-----------dataource-----" + dataSource.toString());
        return new DataSourceTransactionManager(dataSource);
    }
    @Bean("sqlSessionTemplate2")
    public SqlSessionTemplate sqlSessionTemplate(@Qualifier("sqlSessionFactory2")SqlSessionFactory sqlSessionFactory) {
        System.out.println("-----------sqlSessionFactory-----" + sqlSessionFactory.toString());

        return new SqlSessionTemplate(sqlSessionFactory);
    }
}
