Mybatis框架不同命名空間相同查詢id出現queryById is ambiguous in Mapped Statements collection

異常簡略信息如下：

org.apache.ibatis.exceptions.PersistenceException: 

### Error querying database.  Cause: java.lang.IllegalArgumentException: queryById is ambiguous in Mapped Statements collection 
(try using the full name including the namespace, or rename one of the entries)
