    /**

     */
    @Bean(name = "sqlserverDataSource")
    @Primary
    @ConfigurationProperties(prefix = "spring.datasource.primary")
    public HikariDataSource getSqlserverDateSource() {
        return new HikariDataSource();
    }

    /**
     * @param datasource 数据源
     * @return SqlSessionFactory
     * @Primary 默认SqlSessionFactory
     */
    @Bean(name = "sqlserverSqlSessionFactory")
    @Primary
    public SqlSessionFactory sqlserverSqlSessionFactory(@Qualifier("sqlserverDataSource") DataSource datasource) throws Exception {
        SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
        bean.setDataSource(datasource);
        //mybatis扫描xml所在位置
        bean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath*:mapper/sqlserver/*.xml"));
        return bean.getObject();
    }

    @Bean("sqlserverSessionTemplate")
    @Primary
    public SqlSessionTemplate sqlserverSqlSessionTemplate(@Qualifier("sqlserverSqlSessionFactory") SqlSessionFactory sqlSessionFactory) {
        return new SqlSessionTemplate(sqlSessionFactory);
    }
}

注意配置类配置了扫描路径一定要关闭配置文件中的的扫描

#mybatis.mapper-locations=classpath:mapper//.xml
