本章節教學視頻位置： https://pan.baidu.com/s/1_TiILfFGKD4JY7FTEQ9kNQ Maven: 用來管理項目依賴,構件 maven中央庫：http://repo1.maven.org/maven2/ maven國內鏡像：http://maven.aliyun.com/nexus/content/groups/public maven本地庫： 查詢maven依賴(http://mvnrepository.com/) 在maven庫中，每個maven構建由Group Id, Artifact Id, Version唯一標識。 Maven環境搭建 1． 下載apache-maven-3.5.0-bin.zip 2． 修改conf目錄下的setting.xml //設置maven本地庫 ~~~ <localRepository>d:/.m2/repository</localRepository> <!--設置maven鏡像（從哪下載）--> <mirror> <id>nexus-aliyun</id> <mirrorOf>*</mirrorOf> <name>Nexus aliyun</name> <url>http://maven.aliyun.com/nexus/content/groups/public</url> </mirror> ~~~ 3. 在eclipse中配置maven  4. 創建maven工程(create a simple project(skip archetype selection)) 填寫Group Id, Artifact Id, Version  注意：第一個使用maven創建工程會比較慢，因為需要聯網下載創建maven工程所必須的構建。 工程類型為war的工程需要web.xml(工程右鍵：JAVAEE Tools->Generate Deployement Descriptor Stub) 5. 編寫POM文件（depencies & build） ~~~ <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/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.neuedu.test</groupId> <artifactId>myvote</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <!--配置依賴 --> <dependencies> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.0.1</version> <scope>provided</scope> </dependency> <!--<dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> --> <!-- 配置spring基礎依賴 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>4.2.5.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>4.2.5.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>4.2.5.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>4.2.5.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>4.2.5.RELEASE</version> </dependency> <!-- 配置spring數據庫連接池 --> <dependency> <groupId>commons-pool</groupId> <artifactId>commons-pool</artifactId> <version>1.3</version> </dependency> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-dbcp2</artifactId> <version>2.0</version> </dependency> <!-- 配置springmvc功能 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.2.5.RELEASE</version> </dependency> <!-- 配置springmvc文件上傳 --> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>1.3.2</version> </dependency> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.3.1</version> </dependency> <!-- 配置spring jackson --> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.5.3</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>2.5.3</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-annotations</artifactId> <version>2.5.3</version> </dependency> <!-- 配置mybatis --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.2.5.RELEASE</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.2.7</version> </dependency> <!-- 配置mybatis和spring整合 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.4</version> </dependency> <!-- 配置mysql依賴 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.40</version> </dependency> <!--配置日志--> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.25</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.7.25</version> <!-- <scope>test</scope> --> </dependency> </dependencies> <!-- 配置build環境 --> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.2</version> <configuration> <source>1.7</source> <target>1.7</target> <encoding>utf-8</encoding> </configuration> </plugin> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <version>2.2</version> <configuration> <port>8080</port> <path>/myvote</path> </configuration> </plugin> </plugins> </build> </project> ~~~ 注意：第一次maven build會比較慢，因為需要聯網下載所有依賴。 若想使用jdk1.8, tomcat8, 請參考https://blog.csdn.net/wild46cat/article/details/52412330 運行maven工程（2種方式） 1. 原來的方式，設置jdk, 部署tomcat 2. Maven命令方式： 工程右鍵-》run as maven build -> tomcat7:run
