一、MAVEN下载安装
maven的下载地址：http://maven.apache.org/download.cgi
解压之后路径 D:\java\apache-maven-3.6.2;
新增系统变量【MAVEN_HOME】，变量名替换成自己本地解压路径
系统变量【Path】追加值：%MAVEN_HOME%\bin
本地仓储配置文件：D:\java\apache-maven-3.6.2\conf\settings.xml
在maven目录下创建本地存储文件夹repository，设置本地存储路径 D:\java\apache-maven-3.6.2\repository
<localRepository>D:\java\apache-maven-3.6.2\repository</localRepository>直接访问maven<localRepository>D:\java\apache-maven-3.6.2\repository</localRepository>公共仓库的速度比较慢，所以推荐使用阿里的maven仓库镜像，在mirrors节点下，新增如下内容
<mirror> <id>aliyun</id> <name>aliyun</name> <url>http://maven.aliyun.com/nexus/content/groups/public/</url> <mirrorOf>central</mirrorOf> </mirror>设置默认jdk，在profiles节点下，新增如下内容(可以省略，在pom.xml配置也行)
<profile> <id>nexus</id> <repositories> <repository> <id>central</id> <url>http://repo.maven.apache.org/maven2</url> <snapshots> <enabled>false</enabled> </snapshots> </repository> <repository> <id>ansj-repo</id> <name>ansj Repository</name> <url>http://maven.nlpcn.org/</url> <snapshots> <enabled>false</enabled> </snapshots> </repository> </repositories> </profile>二、MAVEN配置
Maven项目目录结构
|----src
| |----main
| | |----java ―― java文件
| | |----resource ――资源文件
| | |----webapp ――jsp/html/css/image/js文件
| |----test
| | |----java ――测试java文件
| | |----resource ――资源文件
|----target ――项目输出位置
|----pom.xml ――maven项目的标志
eclipse设置Maven
在Window----Preferences中找到Maven节点----User Setting，设置如下图：
点击Installations节点，添加maven runtime如下图所示
三、eclipse创建Maven工程
点击File----New----Maven Project(默认有的话)或者File----New----Other，选择maven文件夹，点击Maven Project如下图所示
点击Next，选择默认工作空间位置，选择web类型，再点击Next
填写GroupID、ArtifactID，点击Finish完成maven项目web工程的创建
Group ID：相当于一个组织
Artifact ID：相当于这个组织下的一个具体项目
Packege：根据Group ID和Artifact ID生成一个默认的名称
四、配置的修改
在项目上右键，查看项目信息，默认的Dynamic Web Module为2.3，使用Tomcat 8.5，需要修改为3.1
(1).找到maven工程所在目录下org.eclipse.wst.common.project.facet.core.xml此文件
(2).maven工程下的web.xml文件替换为
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1" metadata-complete="true"> </web-app> (3).pom.xml文件中修改build节点，添加如下内容
<plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> </plugins> (4).在项目上右键，找到Maven属性下的Update Project
(5).选择该项目进行更新，如果怕不能强制更新，可以勾选Force Update of Snapshots/Releases，更新完毕再一次查看Dynamic Web Module是否为3.1
右键项目--Properties--Deployment Assembly，移除target
五、案例测试
目录结构
- Pom.xml再添加如下内容
<properties> <srping.version>4.0.2.RELEASE</srping.version> <mybatis.version>3.2.8</mybatis.version> <slf4j.version>1.7.12</slf4j.version> <log4j.version>1.2.17</log4j.version> </properties> <dependencies> <!-- spring框架包 start --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${srping.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${srping.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-oxm</artifactId> <version>${srping.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${srping.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${srping.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${srping.version}</version> </dependency> <dependency> <groupId>org.apache.geronimo.bundles</groupId> <artifactId>aspectjweaver</artifactId> <version>1.6.8_2</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${srping.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${srping.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-expression</artifactId> <version>${srping.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>${srping.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${srping.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${srping.version}</version> </dependency> <!-- spring框架包 end --> <!-- mybatis框架包 start --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.2</version> </dependency> <!-- mybatis框架包 end --> <!-- 数据库驱动 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>8.0.17</version> </dependency> <!-- 导入dbcp的jar包，用来在applicationContext.xml中配置数据库 --> <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version>1.4</version> </dependency> <!-- jstl标签类 --> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- log start --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> </dependency> <!-- log END --> <!-- Json --> <!-- 格式化对象，方便输出日志 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.6</version> </dependency> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.13</version> </dependency> <!-- 上传组件包 start --> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.3.1</version> </dependency> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.4</version> </dependency> <dependency> <groupId>commons-codec</groupId> <artifactId>commons-codec</artifactId> <version>1.10</version> </dependency> <!-- 上传组件包 end --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> <scope>provided</scope> </dependency> <!-- java ee包 --> <dependency> <groupId>javax</groupId> <artifactId>javaee-api</artifactId> <version>7.0</version> <scope>provided</scope> </dependency> </dependencies>2.datasource.properties

CREATE TABLE `user` ( `userid` INT(11) NOT NULL AUTO_INCREMENT, `username` VARCHAR(255) DEFAULT NULL, `password` VARCHAR(255) DEFAULT NULL, `email` VARCHAR(255) DEFAULT NULL, `phone` VARCHAR(255) DEFAULT NULL, `status` VARCHAR(255) NOT NULL DEFAULT '0', `code` VARCHAR(255) DEFAULT NULL, PRIMARY KEY (`userid`) ) ENGINE=INNODB AUTO_INCREMENT=16 DEFAULT CHARSET=utf8;13.项目部署
配置 Tomcat 访问权限，tomcat中tomcat-user.xml的配置(tomcat根目录/conf/tomcat-users.xml)
<role rolename="manager-gui"/> <role rolename="manager-script"/> <role rolename="manager-jmx"/> <role rolename="manager-status"/> <user password="123456" username="root" roles="manager-gui,manager-script,manager-jmx,manager-status" />双击 tomcat 解压包中 bin 目录下的 startup.bat 命令进行启动Tomcat服务器。在浏览器地址来中进行访问http://127.0.0.1:8080/manager/
输入用户名root，密码123456进行登录，如果顺利则请进入下一步。
配置maven的setting.xml
在 conf/setting.xml 文件中的标签 <servers> 添加如下内容
<server> <!--通过标签名字让 maven 去关联我们的 Tomcat 服务器--> <id>tomcat8</id> <!--username 和 password 一定要和 tomcat 中的 tomcat_user.xml 中一致--> <username>root</username> <password>123456</password> </server>在 pom.xml 文件的plugins子节点中添加如下内容
<plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <version>2.2</version> <configuration> <url>http://127.0.0.1:8080/manager/text</url> <!--关联id--> <server>tomcat8</server> <username>root</username> <password>123456</password> <!--访问的路径(项目名)--> <path>/ssm01</path> <update>true</update> </configuration> </plugin>先运行Tomcat目录下/bin/startup.bat
访问如下图表示配置成功
附：maven命令
执行命令
1）Run as → clean install
2）Run as → tomcat7:deploy 注：第1次部署执行
3）Run as → tomcat7:redeploy 注：第2次或以后需要重新发布执行
4）Run as → tomcat7:run 注：部署到 tomcat 中启动
在此过程中遇到的错误
启动tomcat，在进行编译构建
用Mybatis去操作底层数据库的时候，需要用到xml配置文件，一般我们是把配置文件和dao放置在同一层目录。操作maven项目的时候，我们可能会遇到无法读取到dao对应的mapper.xml文件。在pom.xml的build节点中添加如下内容
<resources> <resource> <directory>src/main/resources</directory> <includes> <include>**/*.properties</include> <include>**/*.xml</include> </includes> </resource> <resource> <directory>src/main/java</directory> <includes> <include>**/*.properties</include> <include>**/*.xml</include> </includes> </resource> </resources> 或者 <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>build-helper-maven-plugin</artifactId> <version>1.8</version> <executions> <execution> <id>add-resource</id> <phase>generate-resources</phase> <goals> <goal>add-resource</goal> </goals> <configuration> <resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.xml</include> </includes> </resource> </resources> </configuration> </execution> </executions> </plugin> 再或者 <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>build-helper-maven-plugin</artifactId> <version>1.8</version> <executions> <execution> <id>add-resource</id> <phase>generate-resources</phase> <goals> <goal>add-resource</goal> </goals> <configuration> <resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.xml</include> </includes> </resource> </resources> </configuration> </execution> </executions> </plugin>来源：51CTO
