SSM整合(Spring+SpringMVC+Mybatis)

1、准备好需要的jar包
2、项目中配置文件目录

applicationContext.xml:spring的配置文件，配置了数据源和mybatis的相关信息
log4j.properties:日志相关配置
spring-mvx.xml:SpringMVC相关配置
sqljdbc.properties:数据库链接信息相关配置
3、配置文件详解
3.1、applicationContext.xml

            <mapper namespace="com.wxcoming.core.dao.BaseDao"> 
                
                <select id="findAllWare" resultType="com.wxcoming.core.bean.Ware">

                select>
            mapper>

配置文件的内容到这里就结束了，java代码的编写应该不难，这里就不写了。在整合的过程中，可能有的人喜欢将mybatis和spring文件分开，所有SSM的整合没有唯一的标准，主要是以下内容：
1、spring注解
2、spring扫描，指定扫描的范围
3、数据库信息的引入
4、数据源
5、数据库工厂
6、关系mapper.xml
7、springMVC开启注解
8、springMVC的视图配置
9、在wem.xml中配置springMVC的前端控制器
10、在wem.xml中配置编码处理
这里讲了些主要的配置信息，可能漏了些，以后想起再补上。
