intellij idea 构建 基于spring springmvc hibernate的maven项目《一》
下载软件环境暂且不提
基本步骤如下
1.在intellij idea中创建project
填写工程名,包名
下面一直next知道finish。这样一个工程就建立了。
刚建立的工程目录结构如下
2.点击工程右键 Add Frameworks Support按如下选择spring springmvc hibernate
完成后,在file下面选择Project Structure,会提示没有找到依赖包,点击fix it ,会自动下载依赖包。
配置文件
或者 add frameworks support步骤省略,直接将ssh的依赖包配置pom.xml中
pom.xml

依赖包下载完成后,在工程中新建配置文件ApplicationContext.xml 和 dispatch-servlet.xml,并修改web.xml。
具体如下:在resource目录下建立applicationContext.xml
applicationContext.xml

连接数据库的时候需要配置参数
jdbc.properties
#zouy Tomcat JDBC jdbc.driverClass = com.mysql.jdbc.Driver jdbc.url = jdbc:mysql://127.0.0.1:3306/db jdbc.username = root jdbc.password = root #Tomcat JDBC #hibernate hibernate.show_sql = true hibernate.format_sql = true hibernate.dialect = org.hibernate.dialect.MySQLDialect #hibernate cache

tomcat配置
edit configurations
点击+号,选择tomcatserver
deployment 选择fix it 将工程部署
运行报错,需要把jar包放到web-inf下的lib文件夹中
运行成功
基本环境搭建完毕,接下来要写具体的业务了。
