配置好后，发现网上已经做好的了， 不过，跟我的稍有不同， 我这里再拿出来现个丑：
properties 文件自不必说，关键是这里的xml：

因为，我们使用了 MapperScannerConfigurer ，dao bean是spring 动态生成的，我们可以不用写dao 实现了。 但是我们需要配置 MapperScannerConfigurer ，指向我们需要使用双数据源的 package， 这个package 最好和之前数据源不同， 以示区别 。
同时， 我们需要配置 transaction-manager ，这里的transaction-manager 是一个注解式的事务管理器。
dao 是可以不用写了。但是， 接口是必须的，我开始的时候是直接复制了原有的dao 接口， 但是发现有问题就是 dao 的bean 的name 和原有的发生冲突。 怎么办呢， 只有改名了， 我就直接加了个2：
/* * Powered By luokai * Since 2014 - 2017 */ package com.dffk.dfintop_2.credit; import com.dffk.dfintop.bussiness.credit.domain.CustomerInfo; import com.dffk.dfintop.common.exception.CRUDException; import com.dffk.dfintop.framework.system.domain.SysUser; import java.util.List; /** * @author luokai * @version 1.0 * @since 1.0 */ public interface CustomerInfoMapper2 { /** * 根据ID查询单条数据 * @param id * @return */ public CustomerInfo findOne(String id); /** * 查询数据集合 * @param customerInfo * @return */ public List<CustomerInfo> findList(CustomerInfo customerInfo); /** * 查询数据TREE * @param sysUser * @return * @throws CRUDException */ public List<CustomerInfo> findTree(SysUser sysUser); /** * 查询数据TREE * @param customerInfo * @return * @throws CRUDException */ public List<CustomerInfo> findAll(CustomerInfo customerInfo); /** * 查询数据总数 * @param customerInfo * @return */ public Integer findTotal(CustomerInfo customerInfo); /** * 数据新增 * @param customerInfo */ public void save(CustomerInfo customerInfo); /** * 数据修改 * @param customerInfo */ public void update(CustomerInfo customerInfo); /** * 数据删除 * @param listId */ public void delete(List<String> listId); }
然后就是使用了， 使用很简单， 通过@Autowired 注解就行了：
@Service public class XxxService extends BaseService { @Autowired private CustomerInfoMapper customerInfoMapper; @Autowired private ContractInfoMapper contractInfoMapper; @Autowired private ImageInfoMapper imageInfoMapper; @Autowired private BusinessIntoMapper businessIntoMapper; @Autowired private com.dffk.dfintop_2.credit.CustomerInfoMapper2 customerInfoMapper2; @Autowired private com.dffk.dfintop_2.credit.ContractInfoMapper2 contractInfoMapper2; @Autowired private com.dffk.dfintop_2.credit.ImageInfoMapper2 imageInfoMapper2; @Autowired private com.dffk.dfintop_2.credit.BusinessIntoMapper2 businessIntoMapper2; ... }
// 注，
BaseService 使用了 @Transactional 注解，也就是注解方式启用了事务管理器。
@Transactional(readOnly = false)
public abstract class BaseService {
}
