spring中配置邮件发送服务
参考：https://juejin.im/entry/5898277b2f301e00696bea1d
需要的邮件jar包
<!-- https://mvnrepository.com/artifact/javax.mail/mail -->
<dependency>
<groupId>javax.mail</groupId>
<artifactId>mail</artifactId>
<version>1.4.7</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>4.3.10.RELEASE</version>
</dependency>1、在applicationContent.xml中配置邮件相关参数
<!-- 加载systemInfo.properties属性文件 -->
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="properties" ref="configProperties" />
</bean>
<bean id="configProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
<property name="locations">
<list>
<value>classpath:systemInfo.properties</value>
</list>
</property>
</bean>
<!-- 邮件发送 -->
<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
<property name="host" value="${sys.mail.host}" />
<property name="username" value="${sys.mail.sysEmailAddress}" />
<property name="password" value="${sys.mail.password}" />
<property name="defaultEncoding" value="UTF-8"></property>
<property name="javaMailProperties">
<props>
<prop key="mail.smtp.auth">${sys.mail.smtp.auth}</prop>
<prop key="mail.smtp.timeout">${sys.mail.smtp.timeout}</prop>
<prop key="mail.smtp.port">${sys.mail.smtp.port}</prop>
</props>
</property>
</bean>2、systemInfo.properties属性文件
sys.mail.protocol=smtp
sys.mail.host=smtp.163.com
sys.mail.sysEmailAddress=***@163.com
sys.mail.password=*** #在163邮箱中设置授权码
sys.mail.smtp.auth=true
sys.mail.smtp.timeout=25000
sys.mail.smtp.port=253、EmailSendManager.java接口
package com.mdl.monitor.services;
import javax.mail.MessagingException;
import com.mdl.monitor.bean.SimpleEmail;
public interface EmailSendManager {
/**
* 发送简单邮件
*
* @param simpleEmail
* 简单邮件详情
* @throws MessagingException
*/
void sendEmail(SimpleEmail simpleEmail) throws MessagingException;
}
4、EmailSendManagerImpl.java实现类
package com.mdl.monitor.services.impl;
import java.io.File;
import java.util.Map;
import java.util.Set;
import javax.mail.MessagingException;
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.Component;
import com.mdl.monitor.bean.SimpleEmail;
import com.mdl.monitor.services.EmailSendManager;
@Component("simpleEmailSendManagerImpl")
public class EmailSendManagerImpl implements EmailSendManager {
@Value("${sys.mail.sysEmailAddress}")
private String from; // 发送者
@Autowired
private JavaMailSender mailSender;
@Override
public void sendEmail(SimpleEmail simpleEmail) throws MessagingException {
MimeMessage message = mailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(message, simpleEmail.isAttachment());
/**
* 添加发送者
*/
helper.setFrom(from);
Set<String> toSet = simpleEmail.getToSet();
/**
* 添加接收者
*/
helper.setTo(toSet.toArray(new String[toSet.size()]));
/**
* 添加主题
*/
helper.setSubject(simpleEmail.getSubject());
/**
* 添加正文
*/
helper.setText(simpleEmail.getContent(), simpleEmail.isHtml());
/**
* 添加附件
*/
if (simpleEmail.isAttachment()) {
Map<String, File> attachments = simpleEmail.getAttachments();
if (attachments != null) {
for (Map.Entry<String, File> attach : attachments.entrySet()) {
helper.addAttachment(attach.getKey(), attach.getValue());
}
}
}
mailSender.send(message); // 发送
}
}
5、SimpleEmail.java实体类
package com.mdl.monitor.bean;
import java.io.File;
import java.util.Map;
import java.util.Set;
public class SimpleEmail {
private Set<String> toSet; // 收件人
private String subject; // 主题
private String content; // 正文
private boolean isHtml; // 正文是否是HTML
private Map<String, File> attachments; // 附件路径
private boolean isAttachment; // 是否有附件
public Set<String> getToSet() {
return toSet;
}
public void setToSet(Set<String> toSet) {
this.toSet = toSet;
}
public String getSubject() {
return subject;
}
public void setSubject(String subject) {
this.subject = subject;
}
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
public boolean isHtml() {
return isHtml;
}
public void setHtml(boolean isHtml) {
this.isHtml = isHtml;
}
public Map<String, File> getAttachments() {
return attachments;
}
public void setAttachments(Map<String, File> attachments) {
this.attachments = attachments;
}
public boolean isAttachment() {
return isAttachment;
}
public void setAttachment(boolean isAttachment) {
this.isAttachment = isAttachment;
}
}
6、测试类TestSendEmail.java
package com.mdl.monitor.test;
import java.io.IOException;
import java.util.HashMap;
import java.util.HashSet;
import java.util.Map;
import java.util.Set;

*/
@Test
public void sendHTMLEmail() throws MessagingException, TemplateException, Exception {
SimpleEmail simpleEmail = new SimpleEmail();

}
/**

@Test
