Springmvc 發送郵件功能

一、引入相關jar包

<dependency>
			<groupId>org.apache.velocity</groupId>
			<artifactId>velocity</artifactId>
			<version>1.7</version>
		</dependency>

		<dependency>
			<groupId>org.apache.velocity</groupId>
			<artifactId>velocity-tools</artifactId>
			<version>2.0</version>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-context-support</artifactId>
			<version>4.3.9.RELEASE</version>
		</dependency>

Spring的基本核心jar包沒有在上面寫出來

二、編輯spring配置文件

<bean id="webEmailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
		<property name="host" value="smtp.126.com" />
		<property name="port" value="25" />
		<property name="username" value="XXXXX@126.com" />
		<property name="password" value="**********" />
		<property name="javaMailProperties">
			<props>
				<!--設置是否須要身份驗證 -->
				<prop key="mail.smtp.auth">true</prop>
			</props>
		</property>
	</bean>
	<bean id="smg" class="org.springframework.mail.SimpleMailMessage">
		<property name="from" value="你的發送郵箱" />
		<property name="to" value="你的接受郵箱" />
	</bean>

	<bean id="velocityEngine"
		class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
		<property name="velocityProperties">
			<props>
				<prop key="file.resource.loader.cache">false</prop>
				<prop key="file.resource.loader.modificationCheckInterval">3</prop>
				<prop key="resource.loader">file</prop>
				<prop key="file.resource.loader.path">.</prop>
				<prop key="file.resource.loader.class">
					org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader
				</prop>
				<prop key="velocimacro.library"></prop>
				<prop key="input.encoding">UTF-8</prop>
				<prop key="output.encoding">UTF-8</prop>
				<prop key="default.contentType">application/x-www-form-urlencoded; charset=UTF-8</prop>
			</props>
		</property>
	</bean>

@Controller
@RequestMapping("/mail")
public class WebEmail {

    @Resource(name = "webEmailSender")
    private JavaMailSenderImpl mailSender;
    @Resource(name = "smg")
    private SimpleMailMessage MailMessage;
    @Resource
    private VelocityEngine velocityEngine;

    @RequestMapping(value="test1", method=RequestMethod.GET)
    @ResponseBody
    public void send(@RequestParam("s") String s) {
        System.out.println(s);
        try {
            MimeMessage mimeMessage = mailSender.createMimeMessage();
            MimeMessageHelper messageHelper = new MimeMessageHelper(mimeMessage, true, "UTF-8");
            messageHelper.setFrom(MailMessage.getFrom());
            messageHelper.setSubject(s); //主題
            Map<String, Object> map = new HashMap<String, Object>();
            map.put("username", "xxxx");
            map.put("url", "http://www.baidu.com");  
            map.put("email", "gjni@worthtech.net");
            String result = VelocityEngineUtils.mergeTemplateIntoString(velocityEngine, "config/welcome.vm", "UTF-8",map); 
            messageHelper.setText(result, true);   //內容
            messageHelper.setTo(MailMessage.getTo()); //發送給
            mailSender.send(mimeMessage);    //發送郵件
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

MimeMessageHelper(mimeMessage, true, "UTF-8") 要設置成UTF-8 ，若是不這樣會發現，發送的郵件內容中文爲亂碼
