创建一个maven项目(项目代码最后见):

项目组织、名称、版本等等:

然后Next、Next(注意检查项目路径),删除自动生成日志配置文件和applicationContext.xml项目如下:

pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

    <modelVersion>4.0.0</modelVersion>
    <packaging>war</packaging>

    <name>springproject</name>
    <groupId>com.lingkang.top</groupId>

    <version>1.0-SNAPSHOT</version>

    <properties>
        <!--可以在spring官网看最新版本 https://spring.io/projects/spring-framework#learn-->
        <!-- 用最新的spring5  2019年10月5日 21:21:39最新版 -->
        <spring.version>5.2.0.RELEASE</spring.version>
    </properties>

    <dependencies>
        <!--spring 核心包-->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <!--spring web包-->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <!-- springMVC-->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>${spring.version}</version>
            <scope>compile</scope>
        </dependency>

        <!--jstl for jsp page-->
        <dependency>
            <groupId>jstl</groupId>
            <artifactId>jstl</artifactId>

    </dependencies>

    <build>
        <plugins>
            <!--
              配置一个运行的tomcat插件,注意spring4才支持,spring5就不支持tomcat7插件
              下面的插件并不适用
              可参考Apache官网:http://tomcat.apache.org/maven-plugin-2.2/
            -->
            <!--<plugin>
                <groupId>org.apache.tomcat.maven</groupId>

                    <uriEncoding>UTF-8</uriEncoding>
                </configuration>
            </plugin>-->
        </plugins>
    </build>

</project>

1、配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://java.sun.com/xml/ns/javaee"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         id="WebApp_ID" version="3.0">
    <!--1、首先呢,要启动spring-->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!--2、启动的时候,添加spring的配置 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            classpath:applicationContext.xml
        </param-value>
    </context-param>

    <!--3、启动spring MVC-->
    <servlet>
        <servlet-name>springMVC</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:springMVC.xml</param-value>
        </init-param>
        <!--服务器启动就加载Servlet-->
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springMVC</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

2、applicationContext.xml和springMVC.xml

applicationContext.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!-- spring的配置文件,这里主要配置和业务逻辑相关的内容 -->
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
        http://www.springframework.org/schema/tx">

</beans>

springMVC.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="
  http://www.springframework.org/schema/beans
  http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
  http://www.springframework.org/schema/context
  http://www.springframework.org/schema/context/spring-context-3.0.xsd
  http://www.springframework.org/schema/mvc
  http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
    <!-- 默认的注解映射的支持 -->
    <mvc:annotation-driven/>

    <!-- 自动扫描控制器controller -->
    <context:component-scan base-package="com.lingkang.top.springproject.controller" />

    <!-- 定义跳转的文件的前后缀 ,配置视图 -->
    <bean
            class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀,变成一个 可用的url地址 -->
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

</beans>

3、运行项目:

添加tomcat运行服务器

添加war:

效果如下:

整合spring完毕!这是一个最基础的Maven Spring模板,后续在此模板的基础上加入数据库、事务等操作即可

项目整体如下:
