Springmvc 发送邮件功能

1、引入相关jar包

1        <dependency>
2			<groupId>org.apache.velocity</groupId>
3			<artifactId>velocity</artifactId>
4			<version>1.7</version>
5		</dependency>
6
7		<dependency>
8			<groupId>org.apache.velocity</groupId>
9			<artifactId>velocity-tools</artifactId>
10			<version>2.0</version>
11		</dependency>
12		<dependency>
13			<groupId>org.springframework</groupId>
14			<artifactId>spring-context-support</artifactId>
15			<version>4.3.9.RELEASE</version>
16		</dependency>

Spring的基本核心jar包没有在上面写出来

2、编辑spring配置文件

1<bean id="webEmailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
2		<property name="host" value="smtp.126.com" />
3		<property name="port" value="25" />
4		<property name="username" value="XXXXX@126.com" />
5		<property name="password" value="**********" />
6		<property name="javaMailProperties">
7			<props>
8				<!--设置是否需要身份验证 -->
9				<prop key="mail.smtp.auth">true</prop>
10			</props>
11		</property>
12	</bean>
13	<bean id="smg" class="org.springframework.mail.SimpleMailMessage">
14		<property name="from" value="你的发送邮箱" />
15		<property name="to" value="你的接受邮箱" />
16	</bean>
17
18	<bean id="velocityEngine"
19		class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
20		<property name="velocityProperties">
21			<props>
22				<prop key="file.resource.loader.cache">false</prop>
23				<prop key="file.resource.loader.modificationCheckInterval">3</prop>
24				<prop key="resource.loader">file</prop>
25				<prop key="file.resource.loader.path">.</prop>
26				<prop key="file.resource.loader.class">
27					org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader
28				</prop>
29				<prop key="velocimacro.library"></prop>
30				<prop key="input.encoding">UTF-8</prop>
31				<prop key="output.encoding">UTF-8</prop>
32				<prop key="default.contentType">application/x-www-form-urlencoded; charset=UTF-8</prop>
33			</props>
34		</property>
35	</bean>
36
37@Controller
38@RequestMapping("/mail")
39public class WebEmail {
40
41    @Resource(name = "webEmailSender")
42    private JavaMailSenderImpl mailSender;
43    @Resource(name = "smg")
44    private SimpleMailMessage MailMessage;
45    @Resource
46    private VelocityEngine velocityEngine;
47
48    @RequestMapping(value="test1", method=RequestMethod.GET)
49    @ResponseBody
50    public void send(@RequestParam("s") String s) {
51        System.out.println(s);
52        try {
53            MimeMessage mimeMessage = mailSender.createMimeMessage();
54            MimeMessageHelper messageHelper = new MimeMessageHelper(mimeMessage, true, "UTF-8");
55            messageHelper.setFrom(MailMessage.getFrom());
56            messageHelper.setSubject(s); //主题
57            Map<String, Object> map = new HashMap<String, Object>();
58            map.put("username", "xxxx");
59            map.put("url", "http://www.baidu.com");  
60            map.put("email", "gjni@worthtech.net");
61            String result = VelocityEngineUtils.mergeTemplateIntoString(velocityEngine, "config/welcome.vm", "UTF-8",map); 
62            messageHelper.setText(result, true);   //内容
63            messageHelper.setTo(MailMessage.getTo()); //发送给
64            mailSender.send(mimeMessage);    //发送邮件
65        } catch (Exception e) {
66            e.printStackTrace();
67        }
68    }
69
70}

MimeMessageHelper(mimeMessage, true, "UTF-8") 要设置成UTF-8 ，如果不这样会发现，发送的邮件内容中文为乱码
