mybatis通配符引用报错的问题XML fragments parsed from previous mappers does not contain value

写mapper A的时候，发现内容太长，于是把被引用的refid单独抽出来成为一个新的mapper文件，A中只保留了直接对外的接口申请了，于是就有了mapper B 文件。

在A文件里面引用B的sql，如：

    

结果报错：

org.apache.ibatis.builder.IncompleteElementException: Could not find SQL statement to include with refid 'A.where_2'

后来发现 B文件中B.where_1引用了，原来是在引用的时候没有加前缀，改成这样就可以了.

最终是这样的：

A文件：

   
        select count(*)
        from X a

    

  

B文件：

where a.id =#{id,jdbcType=VARCHAR}

      B.where_2" />     

a.name =#{name,jdbcType=VARCHAR}

B文件最开始where_1中引用where_2时没有加B.的前缀，所有报错了。原来where_1在引入到A文件后，直接把where_2也引用过去了，然后相当于是A文件引用的where_2.
