spring-mybatis-springMVC 整合

2021-09-18 10:05:02

这是一个spring mybatis springMVC 的整合里面包括日志，druid，的配置。可以说是一个现成的模板，直接复制下来就能用。

首先是web.xml

web.xml 中包括

Spring beans 配置文件所在目录
utf-8编码过滤器
spring的监听器
springmvc的配置
druid的配置
默认的首页index

这里说一下，springmvc没有指定springmvc的配置文件的位置，因为springmvc默认是去web-info文件夹下找spring-servlet.xml的配置文件的。需要注意一下。这里配置druid是因为我们要利用durid来监测我们访问的url，

durid是一个非常出色数据库连接池。非常的强大，他自带的有监控界面，但是需要配置一下。

mvc忽略静态文件的三种方法：https://www.cnblogs.com/banning/p/6195072.html

applicationContext.xml

这之前需要理一下关系。首先作为applicationContext.xml核心文件，肯定需要的是
配置加载的属性文件.properties（数据库连接池用）
配置数据库连接池dataSource（里面需要一些配置就不说了账号密码驱动之类的。。。）
配置sqlSessionFactory（这个是mybatis提供的类，需要的属性有mybatisConfig.xml，数据库连接池dataSource，映射的mapper文件）
配置扫描dao层接口的类（也是mybatis提供的，需要配置的参数有，你这个接口的位置，还有上面的sqlSessionFactory）
需要事务tx（spring-jdbc提供的类，只需要把dataSource扔进去就行）
配置事务的使用方法（一般都是注解，加上一句话就行，具体看代码）
druid的配置（这个可有可无）
