javaMail

用java写了一下简单的发送注册验证邮件的小例子：
核心配置和代码如下：

	<bean id="javaMailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
		<property name="host">
			<value>smtp.mail.yahoo.com.cn</value>
		</property>
		<property name="username">
			<value>djandeclipse</value>
		</property>
		<property name="password">
			<value>＊＊＊＊＊＊</value>
		</property>

	</bean>

	<!-- 可以用spring的类来实例化出Configuration对象 对spring比下面的用 freemarker.template.Configuration 
		实例方便 -->
	<!-- <bean id="configuration" class="org.springframework.ui.freemarker.FreeMarkerConfigurationFactoryBean 
		"> <property name="templateLoaderPath" value="classpath:/com" /> </bean> -->


	<bean id="configuration" class="freemarker.template.Configuration " />
	<bean id="templateLoader" class="freemarker.cache.FileTemplateLoader">
		<constructor-arg index="0" ref="file"></constructor-arg>
	</bean>

	<!--对象中的属性没有set方法时，可以通过向对象的构造方法中传入值来实现注入 要注册构造方法的index属性是从0开始的 -->
	<bean id="file" class="java.io.File">
		<constructor-arg index="0"
			value="/home/dingjin/workspace/javaMail/src/com/" />
	</bean>

		try {
			MimeMessageHelper mimeHelp = new MimeMessageHelper(mime, true,
					"utf-8");
			mimeHelp.setTo("[e-mail]");
			mimeHelp.setFrom("[e-mail]");
			mimeHelp.setSubject("测试邮件");
			// File file = new File("/tmp/aspectjrt.jar");
			// 这个方法表示在内容内加附件如：图片，不过没测试
			// mimeHelp.addInline("file.jar", file);
			// 附件名有中文可以用这个方法解决
			// MimeUtility.encodeText("");
			// mimeHelp.addAttachment(file.getName(), file);
			mimeHelp.setText(getHtmlFormatMailContent());
			javaMailSender.send(mime);
		} catch (Exception e) {

			e.printStackTrace();
		}
	}

	/**
	 * 发送HTML格式的注册验证邮件
	 * 
	 * @return
	 */
	private String getHtmlFormatMailContent() {
		try {
			Template template = configuration.getTemplate("registerUser.html");
			HashMap<String, String> model = new HashMap<String, String>();
			model.put("user", "123");
			model.put("token", "456");
			String content = FreeMarkerTemplateUtils.processTemplateIntoString(
					template, model);
			System.out.println(content);
			return content;
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
			return null;
		}
	}
