本文详细解析了在使用Spring MVC与MyBatis框架时出现的NestedServletException错误，该错误源于IncompleteElementException，具体表现为无法找到resultMap。文章深入探讨了如何正确配置一对多表的映射关系，以避免此类异常发生。

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.apache.ibatis.builder.IncompleteElementException: Could not find result map java.util.ArrayList
	org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:973)

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.apache.ibatis.builder.IncompleteElementException: Could not find result map com.kaoyan.model.Register

mapping里未完成映射,因为涉及到一对多表,就偷懒没有完成各映射,才报错,完成映射就OK
