1、创建maven工程

 完成创建

2、在pom.xml文件中进行配置

a>添加web模块

b>打包方式：war

c>引入依赖 

<packaging>warpackaging>

<dependencies>
    
    <dependency>
        <groupId>org.springframeworkgroupId>
        <artifactId>spring-webmvcartifactId>
        <version>5.3.1version>
    dependency>
    
    <dependency>
        <groupId>ch.qos.logbackgroupId>
        <artifactId>logback-classicartifactId>
        <version>1.2.3version>
    dependency>
    
    <dependency>
        <groupId>javax.servletgroupId>
        <artifactId>javax.servlet-apiartifactId>
        <version>3.1.0version>

        <scope>providedscope>
    dependency>
    
    <dependency>
        <groupId>org.thymeleafgroupId>
        <artifactId>thymeleaf-spring5artifactId>
        <version>3.0.12.RELEASEversion>
    dependency>
dependencies>

scope的分类
1.compile：默认值 他表示被依赖项目需要参与当前项目的编译，还有后续的测试，运行周期也参与其中，是一个比较强的依赖。打包的时候通常需要包含进去

2.test：依赖项目仅仅参与测试相关的工作，包括测试代码的编译和执行，不会被打包，例如：junit

3.runtime：表示被依赖项目无需参与项目的编译，不过后期的测试和运行周期需要其参与。与compile相比，跳过了编译而已。例如JDBC驱动，适用运行和测试阶段

4.provided：打包的时候可以不用包进去，别的设施会提供。事实上该依赖理论上可以参与编译，测试，运行等周期。相当于compile，但是打包阶段做了exclude操作

5.system：从参与度来说，和provided相同，不过被依赖项不会从maven仓库下载，而是从本地文件系统拿。需要添加systemPath的属性来定义路径

3、配置web.xml

1）创建成功，接下来进行web.xml配置文件的配置

 2)具体配置操作

        <filter-name>CharacterEncodingFilterfilter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilterfilter-class>
     
        <init-param>
            <param-name>encodingparam-name>

        <url-pattern>/*url-pattern>
    filter-mapping>
