Maven3实战笔记02坐标和依赖--1

package com.liuyan.account.mail.impl;import javax.mail.MessagingException;import javax.mail.internet.MimeMessage;import org.springframework.mail.javamail.JavaMailSender;import org.springframework.mail.javamail.MimeMessageHelper;import com.liuyan.account.mail.AccountEmailService;public class AccountEmailServiceImpl implements AccountEmailService {private JavaMailSender javaMailSender;public JavaMailSender getJavaMailSender() {return javaMailSender;}public void setJavaMailSender(JavaMailSender javaMailSender) {this.javaMailSender = javaMailSender;}private String systemEmail;public String getSystemEmail() {return systemEmail;}public void setSystemEmail(String systemEmail) {this.systemEmail = systemEmail;}@Overridepublic void sendMail(String to, String subject, String message)throws MessagingException {MimeMessage msg = javaMailSender.createMimeMessage();MimeMessageHelper msgHelper = new MimeMessageHelper(msg);msgHelper.setFrom(systemEmail);msgHelper.setTo(to);msgHelper.setSubject(subject);msgHelper.setText(message);javaMailSender.send(msg);}}

?之后在包/src/test/java编写测试用例

?

package com.liuyan.account.mail;import javax.mail.MessagingException;import org.junit.After;import org.junit.Before;import org.junit.Test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.icegreen.greenmail.util.GreenMail;import com.icegreen.greenmail.util.ServerSetup;public class AccountEmailServiceTest {private GreenMail greenMail;@Beforepublic void startTest() {greenMail = new GreenMail(ServerSetup.SMTP);greenMail.setUser("suhuanzheng7784877@163.com", "1111");greenMail.start();}@Testpublic void sendMail() throws MessagingException {ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");AccountEmailService accountEmailService = (AccountEmailService) ctx.getBean("accountEmailService");String to = "suhuanzheng7784877@163.com";String subject = "测试";String message = "内容";accountEmailService.sendMail(to, subject, message);}@Afterpublic void stop() {greenMail.stop();}}

?单元测试也写完了，之后就是项目构建、打包了。

?运行一下命令。

mvn clean test

?自己的邮箱看看效果，多了一封邮件。Ok，再看本地仓库，唉~~~自己的c盘又添了不少东西。本地仓库会越来越大的。各位使用者要有心理准备，当然可以通过配置的方式转移本地仓库存储位置。

<groupId>com.liuyan.account</groupId><artifactId>MavenAccount-email</artifactId><version>0.0.1-SNAPSHOT</version>

?而其他项目需要你的模块为其服务的时候，也是根据坐标找到你的模块的。这就引出了下面依赖项的配置。这个模块依赖了Spring，不怕，我们从maven仓库中去取依赖就可以了，下面的问题就是：我们需要哪些依赖？这些依赖的版本是什么？

通过已有组件的坐标，我们可以轻易从Maven中心库中获取依赖包

<dependency><groupId>org.springframework</groupId><artifactId>spring-context-support</artifactId><version>2.5.6</version></dependency>

?描述我们这个邮件模块依赖org.springframework.spring-context-support.2.5.6.jar这个东东。果然，运行后在本地仓库中找到了

这个表是嘛意思呢？就是说一个项目的第一直接依赖假如是compile范围，那么它的第二依赖包如果也是compile，那么本项目和第二依赖包的依赖范围就是compile。如果一个项目的第一直接依赖假如是compile范围，那么它的第二依赖包如果是test，那么本项目和第二依赖包不存在任何依赖关系，也是，第一直接依赖包和第二依赖包是测试的时候才用到的。无需影响到其他使用者。
