#配置類

@EnableTransactionManagement
@Configuration
@MapperScan("com.example.test.mapper")
public class MyBatisPlusConfig {
}

 

#啟動類

SpringBootApplication(exclude = DruidDataSourceAutoConfigure.class)
public class TestApplication {
 
    public static void main(String[] args) {
        SpringApplication.run(TestApplication.class, args);

#Service層

1、默認數據源

@Service
public class BaseUserInfoServiceImpl extends ServiceImpl<BaseUserInfoMapper, BaseUserInfo> implements IBaseUserInfoService {
 
}

2、sqlserver-bz數據源

@Service
@DS("sqlserver-bz")
public class YhbServiceImpl extends ServiceImpl<YhbMapper, Yhb> implements IYhbService {
 
}

3、sqlserver-yw數據源

@Service
@DS("sqlserver-yw")
public class ZybrxxbServiceImpl extends ServiceImpl<ZybrxxbMapper, Zybrxxb> implements IZybrxxbService {
 
}
