SSM整合

@TOCSSM 整合
对于ssm整合网上有很多，这里只是自己为大家提供的一个ssm整合框架参考分享，这个是基于maven的管理工具写的
一、创建Maven工程项目

二、添加依赖（因为我的项目在有需要用到分页，json数据处理，所以我引用了这些依赖，不用的删除即可）

1. spring的依赖

• spring-core
• spring-context
• spring-context-support
• spring-beans
• spring-web
• spring-webmvc
• spring-aop
• spring-aspects
• spring-jdbc
• spring-tx

2. mybatis的依赖

• mybatis
• mybatis-spring

3. mysql的依赖

• mysql-connector-java

4. servlet，jsp，jstl等依赖

• javax.servlet-api
• javax.servlet.jsp-api
• jstl
• joda-time

5. json的依赖

• jackson-databind
• jackson-core
• jackson-annotations
• json-lib
• jackson-core-asl
• jackson-mapper-asl

6. 日志依赖

• log4j
• slf4j-api
• slf4j-log4j12

7. druid数据源依赖

• druid

8. pageHelper依赖

• pagehelper

9. lombok依赖

• lombok

log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

将项目部署到Tomcat中，不要忘记将数据库中的密码，数据库，账号更改到你本地的数据库中。
包扫描的地址更改到你创建的包中。
