SpringBoot（十一）：SpringBoot发送邮件

一、依赖

<!-- javax.mail -->
<dependency>
<groupId>com.sun.mail</groupId>
<artifactId>javax.mail</artifactId>
<version>1.6.0</version>
</dependency>

二、邮箱配置

mail.smtp.auth=true
mail.transport.protocol=smtp
mail.send.charset=UTF-8
mail.smtp.port=465
mail.is.ssl=true
mail.host=smtp.163.com
mail.auth.name=xx@163.com
mail.auth.password=
mail.smtp.timeout=5000

三、代码

package cn.aduu.utils;

import com.sun.mail.util.MailSSLSocketFactory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.env.Environment;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Component;

import javax.annotation.PostConstruct;
import javax.mail.internet.MimeMessage;
import java.io.File;
import java.security.GeneralSecurityException;
import java.util.List;
import java.util.Map;
import java.util.Properties;

}

}

四、测试

package cn.aduu.web;

import cn.aduu.utils.EmailUtils;
import com.fasterxml.jackson.core.JsonProcessingException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
* @author zh
* @ClassName cn.aduu.web.EmailController
* @Description
*/
@RestController
public class EmailController {

private static final Logger logger = LoggerFactory.getLogger(EmailController.class);

@RequestMapping("sendEmail")
public String sendEmail() throws JsonProcessingException {
boolean isSend = EmailUtils.sendEmail("这是一封测试邮件", new String[]{"3379218@qq.com"}, null, "<h3><a href='http://www.baidu.com'>百度一下，你就知道</a></h3>", null);
return "发送邮件:" + isSend;
}
