springmvc+spring+mybatis整合心得

搭建公司门户网站。

很久都没有搭建这样的环境了，今天再次搭建环境感到很兴奋，上次配置的是spring+mybatis的环境，用的是配置文件的方式进行配置的，这次改用了注解的方式来配置。

首先去下载spring的jar，如果你去spring的官网是下载不到spring的jar包的。

在这里附上spring下载地址：http://maven.springframework.org/release/org/springframework/spring/

开始搭建环境，创建项目，导入jar，我采用的是最新的spring框架，还需导入aspectjrt.jar  aspectjweaver.jar   cglib-nodep-2.1_3.jar    commons-dbcp-1.4.jar    commons-logging-1.1.1.jar    commons-pool-1.6.jar    jstl.jar    standard.jar    junit-4.4.jar    log4j-1.2.17.jar

然后导入mybatis的jar

附上mybatis的下载地址：https://github.com/mybatis/mybatis-3/releases

加入配置文件：

applicationContext.xml

遇到的问题是在页面中所有的图片在访问.action请求时，然后所有页面图片无法显示。

解决办法是在所有页面写图片路径加上${pageContext.request.contextPath}/
