Maven与eclipse调整

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;	}}

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

<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>

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>
