之前一直使用mybatis+mybatis-spring-1.1.1,系统升级mybatis后使用 mybatis-spring-1.2.2,
再其它配置均为修改的情况下运行出错:
Property ‘sqlSessionFactory‘ or ‘sqlSessionTemplate‘ are required
从SqlSessionDaoSupport 这个类的源码中可以看出,原因是 mybatis-spring-1.2.0
中取消了自动注入
SqlSessionFactory 和
SqlSessionTemplate
/** * Convenient super class for MyBatis SqlSession data access objects. * It gives you access to the template which can then be used to execute SQL methods. * <p> * This class needs a SqlSessionTemplate or a SqlSessionFactory. * If both are set the SqlSessionFactory will be ignored. * <p> * {code Autowired} was removed from setSqlSessionTemplate and setSqlSessionFactory * in version 1.2.0. * * @see #setSqlSessionFactory * @see #setSqlSessionTemplate * @see SqlSessionTemplate * @version $Id$ */ 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; } …… }
1.1.1中代码片段为:
1 public abstract class SqlSessionDaoSupport extends DaoSupport { 2 3 private SqlSession sqlSession; 4 5 private boolean externalSqlSession; 6 7 @Autowired(required = false) 8 public final void setSqlSessionFactory(SqlSessionFactory sqlSessionFactory) { 9 if (!this.externalSqlSession) { 10 this.sqlSession = new SqlSessionTemplate(sqlSessionFactory); 11 } 12 } 13 14 @Autowired(required = false) 15 public final void setSqlSessionTemplate(SqlSessionTemplate sqlSessionTemplate) { 16 this.sqlSession = sqlSessionTemplate; 17 this.externalSqlSession = true; 18 } 19 …… 20 21 }
可能是为了解决多数据源的问题吧,取消了自动注入。没用到多数据源,不太关心这个。
解决方案:因为我们dao层是继承于一个dao基类,所以只要在这个基类中注入任意一个属性即可。 SqlSessionFactory 在spring配置文件中已经配置。
1 public class BaseDaoImpl extends SqlSessionDaoSupport { 2 @Resource 3 public void setSqlSessionFactory(SqlSessionFactory sqlSessionFactory){ 4 super.setSqlSessionFactory(sqlSessionFactory); 5 }
Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required
