注册一般都有邮箱注册的，短信就得花钱了，，，所以把这发邮件功能做个笔记，直接上代码了

application.properties

spring.mvc.view.prefix: /WEB-INF/jsp/spring.mvc.view.suffix: .jsp

#smtp知识这次不做笔记

spring.mail.host=smtp.qq.comspring.mail.port=25spring.mail.username=526614527@qq.comspring.mail.password=**********（这里是你开通QQ邮箱smtp功能时提供的密码，要发1条短信才能开通）spring.mail.properties.mail.smtp.auth=truespring.mail.defaultEncoding=UTF-8spring.mail.protocol=smtpspring.mail.properties.mail.smtp.starttls.enable=truespring.mail.properties.mail.smtp.connectiontimeout=5000spring.mail.properties.mail.smtp.timeout=5000spring.mail.properties.mail.smtp.writetimeout=5000mail.sender=526614527@qq.com#这个是说明是谁发的,要spring.mail.username一样，不然后台报错说认证不一致.mail.sender可以写成别名字，在java代码里照着拿就行了

pom.xml加上这两个依赖文件

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-mail</artifactId></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context-support</artifactId><version>4.0.1.RELEASE</version></dependency>

java代码：

EmailController.java

package sample.jsp;import java.io.File;import javax.mail.internet.InternetAddress;import javax.mail.internet.MimeMessage;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Value;import org.springframework.mail.javamail.JavaMailSender;import org.springframework.mail.javamail.MimeMessageHelper;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;@Controllerpublic class EmailController {@Autowiredprivate JavaMailSender sender;@Value("${mail.sender}")// 拿到配置文件里的名字    private String from;@RequestMapping("/email.do")@ResponseBodyString home() {try {sendEmail();return "Email Sent!";} catch (Exception ex) {return "Error in sending email: " + ex;}}private void sendEmail(){try {MimeMessage message = sender.createMimeMessage();MimeMessageHelper helper = new MimeMessageHelper(message, true, "utf-8");//MimeMessageHelper(message);helper.setValidateAddresses(true);helper.setFrom(new InternetAddress(from));helper.setTo("13719249618@163.com");helper.setText("我是中国人");// 普通的文字//helper.setText("<font color='red'>爱我中华</font>", true);// 带html格式的文字//helper.addAttachment("ShadowsocksR-4.6.1-win.7z", new File("F:"+File.separator+"ShadowsocksR-4.6.1-win.7z"));helper.setSubject("我是中国人");sender.send(message);} catch (Exception e) {e.printStackTrace();}}}

OK，就这么简单！！！
