今天在做ssm项目的时候出现了: 先是出现 了错误: mybatis报错:A query was run and no Result Maps were found for the Mapped Statement 这是因为Dao.xml中的select标签中必须指定要返回的值的类型(注意:是返回值的单个类型,即如果你是返回一个List<User>的话,需要指定的是User) 具体的这种错误的解决办法见:https://www.cnblogs.com/isme-zjh/p/11757155.h…

Result Maps(结果集) resultMap 元素是 MyBatis 中最重要最强大的元素.它就是让你远离 90%的需要从结果 集中取出数据的 JDBC 代码的那个东西, 而且在一些情形下允许你做一些 JDBC 不支持的事 情. 事实上, 编写相似于对复杂语句联合映射这些等同的代码, 也许可以跨过上千行的代码. ResultMap 的设计就是简单语句不需要明确的结果映射,而很多复杂语句确实需要描述它们 的关系,你已经看到简单映射语句的示例了,但没有明确的 resultMap.比如: <s…

1.  Result Maps resultMap元素是Mybatis里面最重要的并且功能最强大的一个元素.(The resultMapelement is the most important and powerful element in MyBatis.)与JDBC从ResultSets中取值相比较它可以使用节省大约90%的代码.不过多的说了,下面开始resutMap之旅~ 一个最简单的例子 首先XML里面定义个resultMap,如下: <resultMap type="com.g…

Result Maps collection already contains value for ...BaseResultMap ...... 这个问题,相信大家在使用mybatis的重新生成 dao,pojo,mapper的时候,都有可能会遇见. 开发过程中,我们改修了表结构,需要重新生成mybatis的配置文件,然后覆盖回原来工程. 往往在发布项目的时候,就会出现这个问题. 个人猜想这是由于mybatis在重新覆盖了配置文件之后,容器发布的时,Spring重新关联mybatis 配置文件…
