如何解决Mybatis--java.lang.IllegalArgumentException: Result Maps collection already contains value for X
引用和提到了一个错误信息"Mapped Statements collection does not contain value for selectOne",这个错误是由于Mybatis在执行数据库操作时找不到对应的SQL语句所引起的。根据这个错误信息,我们可以推测在执行deleteActivityInstance操作时也是同样的原因引起的。解决这个问题的方法是在Mybatis的配置文件中添加对应的映射语句。
可能的解决方法如下:
1. 首先,在Mybatis的配置文件中查找是否有对应的映射语句,即是否在SQL映射文件中定义了名为deleteActivityInstance的语句。
2. 如果没有找到该语句,需要在SQL映射文件中添加一个名为deleteActivityInstance的语句,并确保它的id与Mybatis的配置文件中的映射语句匹配。
3. 如果已经存在该语句,重新检查Mybatis的配置文件中是否正确引用了该映射语句。
总之,当出现Mapped Statements collection does not contain value for deleteActivityInstance的错误时,需要检查Mybatis的配置文件和SQL映射文件,确保映射语句的定义和引用是正确的。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
