Spring Error : No unique bean of type [org.apache.ibatis.session.SqlSessionFactory] is defined

报错信息：

Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire method: public final void org.mybatis.spring.support.SqlSessionDaoSupport.setSqlSessionFactory(org.apache.ibatis.session.SqlSessionFactory); nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No unique bean of type [org.apache.ibatis.session.SqlSessionFactory] is defined: expected single matching bean but found 2...

 

原因：

beans.xml 中定义了两个 SqlSessionFactory bean，而在 SqlSessionDaoSupport 中调用了下面 setSqlSessionFactory()，造成了不唯一。

 

1 @Autowired(required = false)
2   public final void setSqlSessionFactory(SqlSessionFactory sqlSessionFactory) {
3     if (! this.externalSqlSession ) {
4       this. sqlSession = new SqlSessionTemplate(sqlSessionFactory);
5     }
6   }

 

解决方案：

修改 beans.xml 中与 SqlSessionFactory bean 相关的配置。
