Spring:只读事务的独立数据源

谢谢你看这个。

readOnly=false 事务,从属 readOnly=true 交易。

SqlMapClient (我用iBatis)直接。这意味着(如果我没弄错的话)注射 SqlMapClient客户端

public class MyDataService {

    private SqlMapClient sqlMap;

    @Autowired
    public MyDataService (SqlMapClient sqlMap) {
        this.sqlMap = sqlMap;
    }

    @Transactional(readOnly = true)
    public MyData getSomeData() {
        // an instance of sqlMap connected to slave should be used
    }

    @Transactional(readOnly = false)
    public void saveMyData(MyData myData) {
        // an instance of sqlMap connected to master should be used
    }
}

所以问题是-我该怎么做?
