spring+ibatis在spring配置文件中注入sqlmapclient时，一直报错，详情代码见下面

spring3.0注入sqlMapClient的几种方式：
bean定义：









classpath:/context/ibatis/sqlMapConfig.xml







a.在context中装载sqlMapClient并建立sqlMapClientfactory,每次执行sql操作都从factory中获取sqlMapClient.factory获取bean方法：
WebApplicationContext wac = ContextLoader
.getCurrentWebApplicationContext();
SqlMapClient sqlMapClient = wac.getBean("sqlMapClient",
SqlMapClient.class);

b.在每个DAO中使用spring注解注入sqlMapClient:
@Autowired
@Qualifier("sqlMapClient")
private SqlMapClient sqlMapClient;

c.创建BaseDao继承SqlMapClientDaoSupport，所有DAO都继承BaseDao.BaseDao中注入sqlMapClient:
@Autowired
@Qualifier("sqlMapClient")
public void setSqlMapClientForAutowired(SqlMapClient sqlMapClient) {
super.setSqlMapClient(sqlMapClient);
}
该方法实际上是使用了sqlMapclientTemplate并向template注入sqlMapClient。
