Maven与eclipse整合

一. 创建Java项目

第1步：首先导入前面命令行建立的两个maven项目Hello和HelloFriend。
              方法：选择file-->import-->Existing MAVEN PROJECTS选项选择对应项目路径导入即可

第2步：按顺序先后执行Hello和HelloFriend项目的的构建
              方法：右击各自项目pom.xml文件，选择run as中的maven install命令将构件安装至仓库中

第3步：通过eclipse新建第三个maven项目。选择file-->new-->other-->MAVEN PROJECT选项

第4步：在src/main/java中新建文件com.zdp.maven.MakeFriends.java

public class MakeFriends {public String makeFriends(String name){HelloFriend friend = new HelloFriend();friend.sayHelloToFriend("litingwei");String str = "Hey,"+friend.getMyName()+" make a friend please.";System.out.println(str);return str;}}

第5步：在src/test/java中新建文件com.zdp.maven.MakeFriendsTest.java

public class MakeFriendsTest {@Testpublic void testMakeFriends(){MakeFriends makeFriend = new MakeFriends();String str = makeFriend.makeFriends("litingwei");assertEquals("Hey,John make a friend please.",str);}}

第6步：点击根目录pom.xml添加依赖

<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.zdp.maven</groupId><artifactId>MakeFriends</artifactId><version>0.0.1-SNAPSHOT</version><packaging>jar</packaging><name>MakeFriends</name><url>http://maven.apache.org</url><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties><dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.9</version><scope>test</scope></dependency><dependency><groupId>com.zdp.maven</groupId><artifactId>HelloFriend</artifactId><version>0.0.1-SNAPSHOT</version><scope>compile</scope></dependency></dependencies></project>

第7步：右击pom.xml选择run as 中的命令执行即可

二. 创建Web项目

第1步：创建maven web工程

第2步: 继承parent, 修改web项目中 pom.xml文件如下

<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><artifactId>webs</artifactId><packaging>war</packaging><name>webs Maven Webapp</name><parent><groupId>com.zdp.maven</groupId><artifactId>Parent</artifactId><version>0.0.1-SNAPSHOT</version><relativePath>../Parent/pom.xml</relativePath></parent><dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId></dependency><dependency><groupId>com.zdp.maven</groupId><artifactId>MakeFriends</artifactId></dependency></dependencies></project>

第3步：建立测试jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"pageEncoding="UTF-8"%><%@ page import="com.zdp.maven.*"%><%    MakeFriends makeFriends=new MakeFriends();    out.println(makeFriends.makeFriends("wanglipeng"));%>

第4步：模块聚合, 修改parent中 pom.xml

<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.zdp.maven</groupId><artifactId>Parent</artifactId><version>0.0.1-SNAPSHOT</version><packaging>pom</packaging><name>Parent</name><url>http://maven.apache.org</url><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties><modules><module>../Hello</module><module>../HelloFriend</module><module>../MakeFriends</module><module>../webs</module></modules><dependencyManagement><dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.9</version><scope>test</scope></dependency><dependency><groupId>com.zdp.maven</groupId><artifactId>Hello</artifactId><version>0.0.1-SNAPSHOT</version><scope>compile</scope></dependency><dependency><groupId>com.zdp.maven</groupId><artifactId>HelloFriend</artifactId><version>0.0.1-SNAPSHOT</version><scope>compile</scope></dependency><dependency><groupId>com.zdp.maven</groupId><artifactId>MakeFriends</artifactId><version>0.0.1-SNAPSHOT</version><scope>compile</scope></dependency></dependencies></dependencyManagement></project>

第5步：修改web项目, 设置自动部署到tomcat下面

        <build><finalName>web</finalName><plugins><plugin><groupId>org.codehaus.cargo</groupId><artifactId>cargo-maven2-plugin</artifactId><version>1.2.3</version><configuration><container><containerId>tomcat5x</containerId><home>D:/tomcats/apache-tomcat-6.0.32_Demo</home></container><configuration><type>existing</type><home>D:/tomcats/apache-tomcat-6.0.32_Demo</home></configuration></configuration><executions><execution><id>cargo-run</id><phase>install</phase><goals><goal>run</goal></goals></execution></executions></plugin></plugins></build>
