利用idea搭建 maven+SpringMVC开发环境

准备工作:安装idea编辑器，配置好maven环境（idea自带maven环境）和Java环境

1、打开idea编辑器

2、单击“Create New Project”

3、选择“maven”

4、勾选“Create from archetype” 

5、找到并选择“maven-archetype-webapp”

6、点击下一步“next”

7、填写项目信息

8、点击下一步“next”，进入maven信息页面，此处可以修改maven配置文件，安装路径等

9、配置完成后点击下一步“next”，出现项目名和项目在本地的存放路径

10、点击“finish”完成项目项目与maven环境搭建，完成后项目结构如图所示

11、pom.xml依赖

        <!--指定日志输出格式-->
        <encoder>
            <pattern>%d{yyyy-MM-d HH:mm:ss} [%thread] %-5level %logger -%msg%n</pattern>
        </encoder>
    </appender>
    <!--<appender name="permission" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${catalina.home}/logs/permission.log</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <FileNamePattern>${catalina.home}/logs/permission.%d{yyyy-MM-d}.log.gz</FileNamePattern>
        </rollingPolicy>
        <layout class="ch.qos.logback.classic.PatternLayout">
            <pattern>%d{yyyy-MM-d HH:mm:ss} [%thread] %-5level %logger -%msg%n</pattern>
