Eclipse使用maven创建SSM-web项目

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：

         <!-- 上传组件包 end -->
     </dependencies>

     <build>
         <finalName>ssmtest02</finalName>
         <plugins>
             <plugin>
                 <groupId>org.apache.tomcat.maven</groupId>
                 <artifactId>tomcat7-maven-plugin</artifactId>
                 <version>2.1</version>
                 <configuration>
                     <!-- 注意此处的url,修改成tomcat监听的端口即可 -->
                     <url>http://localhost:8080/manager/text</url>
                     <server>tomcat7</server> <!-- 此处的名字必须和maven的settings.xml中配置的ID一致 -->
                     <path>/${project.artifactId}</path> <!-- 此处的名字是项目发布的工程名 -->
                     <server>tomcat7</server>
                     <username>admin</username>
                     <password>password</password>
                 </configuration>
             </plugin>
         </plugins>
     </build>
 </project>

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：

  <role rolename="admin-gui"/>
   <role rolename="admin-script"/>
   <role rolename="manager-gui"/>
   <role rolename="manager-script"/>
   <role rolename="manager-jmx"/>
   <role rolename="manager-status"/>
   <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

 <?xml version="1.0" encoding="UTF-8"?>
 <web-app
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xmlns="http://xmlns.jcp.org/xml/ns/javaee"
     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">
   <display-name>Demo</display-name>
 </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
