1.环境准备
(1)maven：apache-maven-3.5.2，我的maven安装在D:\apache-maven-3.5.2，eclipse中maven配置如下：
先add ，添加好自己的maven，然后才能选中这个maven
(2) jdk：jdk1.7.0_80
(3) tomcat：apache-tomcat-7.0.81 我的tomcat7安装位置在 D:\Tomcat\apache-tomcat-7.0.81-eclipse ，eclipse中tomcat 配置如下：
2. eclipse创建maven web项目
(1) new maven project
(2) 选择目模板： 搜索app选择maven-archetype-webapp 后下一步
(3) 输入组织名：即包名 ,Artifact ID，即项目名，完成后点击 finish
(4) 修改设置，右键单击项目名，选properties，打开如下弹框，选择project facets ,按图中标示步骤操作，完成后点击apply，使之生效
(5) 勾选Dynamic web module,并 修改content directory
(6) 添加缺失的文件夹：src/main/java 一定得是source folder 才可以。这里添加过了。
3. 添加POM文件的SSM框架依赖，如下：

上面的配置需要在maven 的settings.xml 的<servers>标签下，添加如下标签：
以及在tomcat的 conf目录下的tomcat-users.xml中 <tomcat-users>标签里配置如下信息：
1 <role rolename="admin-gui"/> 2 <role rolename="admin-script"/> 3 <role rolename="manager-gui"/> 4 <role rolename="manager-script"/> 5 <role rolename="manager-jmx"/> 6 <role rolename="manager-status"/> 7 <user username="admin" password="password" roles="manager-gui,manager-script,manager-jmx,manager-status,admin-script,admin-gui"/>
4. 补全web.xml 内容
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns="http://xmlns.jcp.org/xml/ns/javaee" 5 xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1"> 6 <display-name>Demo</display-name> 7 </web-app>
建好的项目如下：
5.把项目发布到tomcat ，运行并访问 http://localhost:8080/ssmtest02/ 结果如下
