PersistenceException解决方法

Type interface com.pastor.mapper.CardMapper is not known to the MapperRegistry. 解决方法

出错环境 :

在MyBatis环境下以注解的方法来实现对MySQL数据库一对一的操作

解决方法 :

在MyBatisConfig.xml中给CardMapper接口注册

<mappers>

​	<mapper class="com.pastor.mapper.CardMapper" />

</mappers>

如果不把相对应的另外一个接口注册将会报以下错误

org.apache.ibatis.exceptions.PersistenceException: 

### Error querying database.  Cause: java.lang.IllegalArgumentException: Mapped Statements collection does not contain value for com.pastor.mapper.PersonMapper.selectById

### The error may exist in com/pastor/mapper/CardMapper.java (best guess)

### The error may involve com.pastor.mapper.CardMapper.selectAll

### The error occurred while handling results

### SQL: SELECT * FROM card

### Cause: java.lang.IllegalArgumentException: Mapped Statements collection does not contain value for com.pastor.mapper.PersonMapper.selectById

解决方法 :

把所引用的接口都进行注册

<mappers>

​	<mapper class="com.pastor.mapper.CardMapper" />

​	<mapper class="com.pastor.mapper.PersonMapper" />

</mappers>
