一、项目目录结构:



spring-context.xml 配置文件内容如下:

    <!--ssm 集成 mongodb  --> 
    <import resource="classpath:spring/spring-mongodb.xml"/> 
    
   
 
</beans>

二、Service 类指定数据库(默认数据库:isap)

package com.wlsq.kso.basic; 
 
import org.springframework.transaction.annotation.Transactional; 
 
@Transactional(value = "isap", rollbackFor = Exception.class)   
public abstract class BaseMySqlService { 
 
} 


package com.wlsq.kso.service.impl; 
 
import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.stereotype.Service; 
 
import com.wlsq.kso.basic.BaseMySqlService; 
import com.wlsq.kso.dao.AccountMapper; 
import com.wlsq.kso.entity.Account; 
import com.wlsq.kso.service.IAccountService; 
 
@Service("accountService")  
public class AccountServiceImpl  extends BaseMySqlService implements IAccountService{ 
	@Autowired 
	private AccountMapper accountMapper; 
	@Override 
	public int deleteByPrimaryKey(Integer id) { 
		// TODO Auto-generated method stub 
		return accountMapper.deleteByPrimaryKey(id); 
	} 
 
	@Override 
	public int insert(Account record) { 
		// TODO Auto-generated method stub 
		return accountMapper.insert(record); 
	} 
 
	@Override 
	public int insertSelective(Account record) { 
		// TODO Auto-generated method stub 
		return accountMapper.insertSelective(record); 
	} 
 
	@Override 
	public Account selectByPrimaryKey(Integer id) { 
		// TODO Auto-generated method stub 
		return accountMapper.selectByPrimaryKey(id); 
	} 
 
	@Override 
	public int updateByPrimaryKeySelective(Account record) { 
		// TODO Auto-generated method stub 
		return accountMapper.updateByPrimaryKeySelective(record); 
	} 
 
	@Override 
	public int updateByPrimaryKey(Account record) { 
		// TODO Auto-generated method stub 
		return accountMapper.updateByPrimaryKey(record); 
	} 
 
 
	@Override 
	public Account selectByUserPass(String username, String password) { 
		// TODO Auto-generated method stub 
		return accountMapper.selectByUserPass(username, password); 
	} 
 
	@Override 
	public Account selectByOpenId(String openId) { 
		// TODO Auto-generated method stub 
		return accountMapper.selectByOpenId(openId); 
	} 
 
	@Override 
	public int deleteByUserPassOpenId(String openId) {			 
		// TODO Auto-generated method stub 
		return accountMapper.deleteByUserPassOpenId(openId); 
	} 
 
	@Override 
	public int updateByUserOpenId(Account account) { 
		// TODO Auto-generated method stub 
		return accountMapper.updateByUserOpenId(account); 
	} 
 
 
	@Override 
	public Account checkAccount(String username, String password) { 
		// TODO Auto-generated method stub 
		return accountMapper.checkAccount(username, password); 
	} 
 
	@Override 
	public Account selectByAccount(Account account) { 
		// TODO Auto-generated method stub 
		return accountMapper.selectByAccount(account); 
	} 
 
 
} 


三、Service 指定其他数据实现(XcloudDataServiceImpl 没有实现BaseMysqlService,我们需要通过事务标签transactional 为该service 指定数据库(insurance))

package com.wlsq.kso.service.impl; 
 
import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.stereotype.Service; 
import org.springframework.transaction.annotation.Transactional; 
 
import com.wlsq.kso.dao.XcloudDataMapper; 
import com.wlsq.kso.entity.XcloudData; 
import com.wlsq.kso.service.XcloudDataService; 
 
@Service("xcloudDataService")   
@Transactional(value = "insurance", rollbackFor = Exception.class)   
public class XcloudDataServiceImpl implements XcloudDataService { 
	@Autowired 
	private XcloudDataMapper xcloudData; 
	@Override 
	public int deleteByPrimaryKey(Integer cloudid) { 
		// TODO Auto-generated method stub 
		return xcloudData.deleteByPrimaryKey(cloudid); 
	} 
 
	@Override 
	public int insert(XcloudData record) { 
		// TODO Auto-generated method stub 
		return xcloudData.insert(record); 
	} 
 
	@Override 
	public int insertSelective(XcloudData record) { 
		// TODO Auto-generated method stub 
		return xcloudData.insertSelective(record); 
	} 
 
	@Override 
	public XcloudData selectByPrimaryKey(Integer cloudid) { 
		// TODO Auto-generated method stub 
		return xcloudData.selectByPrimaryKey(cloudid); 
	} 
 
	@Override 
	public int updateByPrimaryKeySelective(XcloudData record) { 
		// TODO Auto-generated method stub 
		return xcloudData.updateByPrimaryKeySelective(record); 
	} 
 
	@Override 
	public int updateByPrimaryKey(XcloudData record) { 
		// TODO Auto-generated method stub 
		return xcloudData.updateByPrimaryKey(record); 
	} 
 
}
