开发环境：sping+springmvc-4.2.x+mybatis-3.1
开发软件：ecplise Mars Release (4.5.0)
异常类型：Property ‘sqlSessionFactory’ or ‘sqlSessionTemplate’ are required
产生所在：在构建baseDao的时候，继承了SqlSessionDaoSupport。在baseDao的方法中调用sqlSessionFactory来执行sql语句。
异常原因：
原因是
mybatis-
spring
-1.2.0之后的版本
中取消了自动注入
SqlSessionFactory
和
SqlSessionTemplate
下面是SqlSessionDaoSupport的源码
package org.mybatis.spring.support;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionTemplate;
import org.springframework.dao.support.DaoSupport;
import org.springframework.util.Assert;
public abstract class SqlSessionDaoSupport extends DaoSupport
{
private SqlSession sqlSession;
private boolean externalSqlSession;
public void setSqlSessionFactory(SqlSessionFactory sqlSessionFactory)
{
if (!this.externalSqlSession)
this.sqlSession = new SqlSessionTemplate(sqlSessionFactory);
}
public void setSqlSessionTemplate(SqlSessionTemplate sqlSessionTemplate)
{
this.sqlSession = sqlSessionTemplate;
this.externalSqlSession = true;
}
public SqlSession getSqlSession()
{
return this.sqlSession;
}
protected void checkDaoConfig()
{
Assert.notNull(this.sqlSession, “Property ‘sqlSessionFactory’ or ‘sqlSessionTemplate’ are required”);
}
}
解决方案：在继承了SqlSessionDaoSupport的基类中，添加一下的代码即可：
@Autowired
public void setSqlSessionFactory(SqlSessionFactory sqlSessionFactory){
super.setSqlSessionFactory(sqlSessionFactory);
}
手动的子类中注入SqlSessionFactory(或SqlSessionTemplate)。
