如果是自己用的Mybatis,不需要考虑对配置文件加密,如果不是,那就需要考虑加密,这篇文章主要讲如何配置CS的Mybatis 因为mybatis好使,所以几乎需要操作数据库的时候,我都会使用mybatis,而且在一个正式的项目中,同时存在BS和CS的程序,都使用的Mybatis,使用的相同mapper文件. Mybatis的XML配置文件正常如下: &?xml version=&1.0& encoding=&UTF-8& ?& &!DOCTYPE

MyBatis 真正的力量是在映射语句中.这里是奇迹发生的地方.对于所有的力量,SQL 映射的 XML 文件是相当的简单.当然如果你将它们和对等功能的 JDBC 代码来比较,你会发现映射文件节省了大约 95%的代码量.MyBatis 的构建就是聚焦于 SQL 的,使其远离于普通的方式. SQL 映射文件有很少的几个顶级元素(按照它们应该被定义的顺序): cache – 配置给定命名空间的缓存. cache-ref – 从其他命名空间引用缓存配置. resultMap – 最复杂,也是最有力量的元
在使用foreach的时候最容易出错的就是collection属性,该属性是必须指定的,在不同情况 下,该属性的值是不一样的,主要有一下3种情况: 1. 如果传入的是单参数且参数类型是一个List的时候,collection属性值为list 2. 如果传入的是单参数且参数类型是一个array数组的时候,collection的属性值为array 3. 如果传入的参数是多个的时候,我们就需要把它们封装成一个Map了,当然单参数也可以封装成map,实际上如果你在传入参数的时候,在breast里面也是会
