springmvc與mybatis整合時 java.lang.IllegalArgumentException: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required 異常

今天在整合springmvc與mybatis時，啟動服務器遇到這樣一個問題，

 by: java.lang.IllegalArgumentException: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required at org.springframework.util.Assert.notNull(Assert.java:112)

異常的意思是  缺少sqlSessionFactory 或者是  sqlSessionTemplate

我的dao層是利用繼承SqlSessionDaoSupport  然后可以直接通過this.getSqlSession() 來進行數據庫的操作。

后來通過搜索以及查看源代碼發現，mybatis-spring 1.2版本沒有自動注入sqlSessionFactory

解決方法是手動注入

public class BaseDaoImpl extends SqlSessionDaoSupport {
    
    @Autowired
    public void setSqlSessionFactory(SqlSessionFactory sqlSessionFactory){  
            super.setSqlSessionFactory(sqlSessionFactory);  
    }
}

然后在將dao實現類繼承BaseDaoImpl就可以使用了

@Repository
public class PersonDaoImpl extends BaseDaoImpl implements PersonDao {

    String ns = "cn.tx.mapper.PersonMapper.";
    @Override
    public void savePerson(Person p) {
        this.getSqlSession().insert(ns+"savePerson", p);
    }

    @Override
    public Person selectPersonById(Integer personId) {
        return this.getSqlSession().selectOne(ns+"selectPersonById", personId);
    }

    @Override
    public void update(Person p) {
        this.getSqlSession().update(ns + "update", p);
    }

    @Override
    public void delete(Integer personId) {
        this.getSqlSession().delete(ns + "delete", personId);
    }

    @Override
    public List<Person> selectPersonByCondition(QueryCondition qc) {
        return this.getSqlSession().selectList(ns + "selectPersonByCondition", qc);
    }

}
