#Could not find result map java #IncompleteElementException #org.apache.ibatis.builder.Inco

本文解析了在MyBatis中常见的错误：使用resultMap属性为java.util.Map时出现的IncompleteElementException。正确做法是将resultMap替换为resultType，并设置其值为java.util.Map。

项目启动报错：

org.apache.ibatis.builder.IncompleteElementException: Could not find result map java.util.Map

 

根据错误提示，检查到以下错误：

resultMap="java.util.Map"

 

正确写法：

resultType="java.util.Map"

这是在测试MyBatis支持的工程时产生的异常。从字面上理解是xml文件中元素不完整，末找到结果集映射类。这是因为resultMap属性设置的值不正确 这里的陷阱是：真正出问题的文件不一定是正在测试的类对应的文件。别的文件出了问题也可能会出错。
