springmvc与mybatis整合时 java.lang.IllegalArgumentException: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required 异常

今天在整合springmvc与mybatis时，启动服务器遇到这样一个问题，

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

异常的意思是  缺少sqlSessionFactory 或者是  sqlSessionTemplate

我的dao层是利用继承SqlSessionDaoSupport  然后可以直接通过this.getSqlSession() 来进行数据库的操作。

后来通过搜索以及查看源代码发现，mybatis-spring 1.2版本没有自动注入sqlSessionFactory

解决方法是手动注入

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

然后在将dao实现类继承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);
    }

}
