SSM 整合案例

Ssm整合

注意事项

Spring mvc+Spring+Mybatis+MySQL
项目结构，以web项目结构整合（还有maven、gradle）
整合日志、事务一个项目中
Idea 2019、JDK12、Tomcat9、MySQL 5.5

项目结构 D:\java\Idea\Idea_spacework\SSMhzy：不会就去找项目案例重新学习

web项目为主结构，建立web目录，目录下有index.jsp和WEB-INF目录，WEB-INF目录可以放JSP文件。
配置文件建立在src目录下，Spring 容器配置文件bean.xml、Spring mvc请求处理配置springmvc-servlet.xml、Mybatis核心配置文件SqlConfig.xml。
程序代码存放位置，src目录下，创建不同的包，dao、controller、service、pojo、util包存放不同的Java类
JSP文件存放位置，WEB-INF目录下创建一个jsp目录，此目录下存储。
静态资源存放位置，在web目录下，和WEB-INF同一级目录创建res目录。

引入jar包

Spring、springmvc基础包及其依赖包
Mybatis核心包及其依赖包
数据库驱动程序包
采用C标签，需要jstl-1.2.jar
引入spring框架和mybaits框架结合的jar，mybatis-spring-1.3.0.jar

配置Tomcat服务器

配置项目结构

配置文件
