【SSM】实战：新闻发布管理系统——开发环境和框架搭建

一、创建项目，引入JAR包

• JSTL标签库JAR包（两个）：taglibs-standard-spec-1.2.5.jar、taglibs-standard-impl-1.2.5.jar。
• Jackson框架所需JAR包（3个）：jackson-annotations-2.8.8.jar、jackson-core-2.8.8.jar、jackson-databind-2.8.8.jar。
• Java工具类JAR包（1个）：commons-lang3-3.4.jar。
• SSM整合JAR包（29个）

二、编写配置文件

在项目src目录下分别创建数据库常量配置文件、Spring配置文件、MyBatis配置文件、SpringMVC配置文件、log4j配置文件以及资源配置文件。
db.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/db_mybatis?serverTimezone=UTC
jdbc.username=root
jdbc.password=root
jdbc.maxTotal=30
jdbc.maxIdle=10
jdbc.initialSize=5
