Maven3搭建spring邮件项目

public class AccountEmailServiceTest {
	
	@Test
	public void testSendMail() throws Exception {
		ApplicationContext ctx = new ClassPathXmlApplicationContext("account-email.xml");
		AccountEmailService accountEmailService = (AccountEmailService) ctx.getBean("accountEmailService");
		String subject = "Test Subject";
		String htmlText = "<h3>I Love You</h3>";
		accountEmailService.sendMail("[e-mail]", subject, htmlText);
		
	}

}

 前几天搞spring+hibernate+struts2，其中一些库的依赖关系搞的我头痛，所以为了避免重蹈覆辙，开始研究一下maven，对以后的项目开发管理都有帮助。

安装maven和安装eclipse插件的文章网上有很多，我就不多说了，默认我的电脑已经有了jdk5，安装了maven3，并安装了eclipse插件。

1.eclipse里建个maven项目：


 项目目录基本都是固定的，如下：

 在项目根目录下修改pom.xml，内容如下：

 

<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/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.ease.account</groupId>
  <artifactId>account-email</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <name>email</name>
  <description>发送邮件</description>
  
  <dependencies>
  	<dependency>
  		<groupId>org.springframework</groupId>
  		<artifactId>spring-core</artifactId>
  		<version>2.5.6</version>
  	</dependency>
  	<dependency>
  		<groupId>org.springframework</groupId>
  		<artifactId>spring-beans</artifactId>
  		<version>2.5.6</version>
  	</dependency>
  	<dependency>
  		<groupId>org.springframework</groupId>
  		<artifactId>spring-context</artifactId>
  		<version>2.5.6</version>
  	</dependency>
  	<dependency>
  		<groupId>org.springframework</groupId>
  		<artifactId>spring-context-support</artifactId>
  		<version>2.5.6</version>
  	</dependency>
  	<dependency>
  		<groupId>javax.mail</groupId>
  		<artifactId>mail</artifactId>
  		<version>1.4.1</version>
  	</dependency>
  	<dependency>
  		<groupId>junit</groupId>
  		<artifactId>junit</artifactId>
  		<version>4.7</version>
  		<scope>test</scope>
  	</dependency>
  </dependencies>
</project>

 

 其中

 

<modelVersion>4.0.0</modelVersion>
  <groupId>com.ease.account</groupId>
  <artifactId>account-email</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <name>email</name>
  <description>发送邮件</description>

 

是这个新建项目的坐标，

 

<dependencies>
	........
</dependencies>

是项目依赖的库，当我们保存pom.xml文件的时候，maven会自动为我们下载XML文件中添加的依赖库，如图：

其中也包括一些上面没有显式声明依赖的，比如commons-logging-1.1.1.jar,那是因为spring-core-2.5.6.jar依赖commons-logging-1.1.1.jar，所以maven也把它下载了，spring-core依赖关系可以参考maven仓库中spring-core目录下的pom文件。

接下来编写具体类：

首先定义邮件发送接口，很简单，就一个方法

 

public interface AccountEmailService {

	void sendMail(String to, String subject, String htmlText) throws Exception;
}

 

 下面是实现类

 

public class AccountEmailServiceImpl implements AccountEmailService {

	private JavaMailSender javaMailSender;
	
	private String systemEmail;
	
	public void sendMail(String to, String subject, String htmlText)
			throws Exception {
		try {
			MimeMessage msg = javaMailSender.createMimeMessage();
			MimeMessageHelper msgHelper = new MimeMessageHelper(msg);
			
			msgHelper.setFrom(systemEmail);
			msgHelper.setTo(to);
			msgHelper.setSubject(subject);
			msgHelper.setText(htmlText, true);
			
			javaMailSender.send(msg);
		} catch(MessagingException e) {
			throw new Exception("发送邮件失败！", e);
		}
		
	}

	public void setJavaMailSender(JavaMailSender javaMailSender) {
		this.javaMailSender = javaMailSender;
	}

	public void setSystemEmail(String systemEmail) {
		this.systemEmail = systemEmail;
	}

}

 

 实现类中的实例属性都是通过spring注入进来，spring配置文件如下：

 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
		xmlns:xsl="http://www.w3.org/2001/XMLSchema-instance"
		xsl:schemaLocation="http://www.springframework.org/schema/beans 
		http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
		
	<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="location" value="classpath:service.properties"></property>
	</bean>		
	
	<bean id="javaMailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
		<property name="protocol" value="${email.protocol}"></property>
		<property name="host" value="${email.host}"></property>
		<property name="port" value="${email.port}"></property>
		<property name="username" value="${email.username}"></property>
		<property name="password" value="${email.password}"></property>
		<property name="javaMailProperties">
			<props>
				<prop key="mail.${email.protocol}.auth">${email.auth}</prop>
			</props>
		</property>
	</bean>
	
	<bean id="accountEmailService" class="com.ease.account.email.AccountEmailServiceImpl">
		<property name="javaMailSender" ref="javaMailSender"></property>
		<property name="systemEmail" value="${email.systemEmail}"></property>
	</bean>
</beans>

 

 配置文件中也用到了属性文件，这样更加灵活

 

email.protocol=smtps
email.host=smtp.gmail.com
email.port=465
email.username=***@gmail.com
email.password=***
email.auth=true
email.systemEmail=***@qq.com

 

 最后，再写一个测试类

 

public class AccountEmailServiceTest {
	
	@Test
	public void testSendMail() throws Exception {
		ApplicationContext ctx = new ClassPathXmlApplicationContext("account-email.xml");
		AccountEmailService accountEmailService = (AccountEmailService) ctx.getBean("accountEmailService");
		String subject = "Test Subject";
		String htmlText = "<h3>I Love You</h3>";
		accountEmailService.sendMail("[e-mail]", subject, htmlText);
		
	}

}

 这个测试类中并没有断言，简单了点，呵呵

好的，最后就是maven大展身手的时候了，在项目名上或者pom.xml上点鼠标右键，如图：

 执行Maven test，

 

 

如果CONSOLE中显示BUILD SUCCESS，则说明测试类成功执行了，并且，图片右下角显示我已经收到了这个邮件了，呵呵。

接下来我们要做的是打包项目，执行Run as下面的Maven install，执行OK以后，我们会在项目的target下面找到打包的文件，如图：

 并且Maven已经把这个项目包放在了Maven仓库中，其它项目可以依赖使用。

当pom.xml中有多个依赖是同一类时，可以进行一些优化，优化后的pom.xml为
