使用ssm框架整合实现Java发送邮件需要先开启邮箱的smtp和pop3服务。实测开启第一个即可，如图

还需要导入一个javax.mail-1.6.2.jar包。

配置mail.properties

#服务器主机名 smtp.xx.com
    mail.smtp.host=smtp.163.com
    mail.smtp.username=xxx@163.com
    #密码/客户端授权码,非邮箱登录密码
    mail.smtp.password=XXXXXXXXX
    #编码字符
    mail.smtp.defaultEncoding=utf-8
    #是否进行用户名密码校验
    mail.smtp.auth=true
    #设置超时时间
    mail.smtp.timeout=20000

配置applicationContext.xml

<context:property-placeholder location="classpath:mail.properties" ignore-unresolvable="true"/>
    	
    	
    	<bean id="javaMailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
    	     <property name="host" value="${mail.smtp.host}"/>
    	     <property name="username" value="${mail.smtp.username}"/>
    	     <property name="password" value="${mail.smtp.password}"/>
    	     <property name="defaultEncoding" value="${mail.smtp.defaultEncoding}"/>
    	     <property name="javaMailProperties">
    	         <props>
    	             <prop key="mail.smtp.auth">${mail.smtp.auth}</prop>
    	             <prop key="mail.smtp.timeout">${mail.smtp.timeout}</prop>
    	         </props>
    	     </property>
    	</bean>

以上就完成了环境配置，接下来编写一个测试类，使用spring的junit测试。

package ts.test;
    
    import java.io.File;
    import java.util.Properties;
    
    import javax.mail.internet.MimeMessage;
    
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.context.annotation.PropertySource;
    import org.springframework.mail.javamail.JavaMailSender;
    import org.springframework.mail.javamail.MimeMessageHelper;
    import org.springframework.test.context.ContextConfiguration;
    import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
    
    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration("classpath:applicationContext.xml")
    @PropertySource("classpath:mail.properties")	//导入mail.properties
    public class TestMail {
    	
    	@Autowired
    	private JavaMailSender javaMailSender;	//在spring中配置的邮件发送的bean
    	
    	@Value("${mail.smtp.username}")	//通过注解获取配置文件属性值
    	String from;	//发件人邮箱
    	String to = "xxx@163.com";	//收件人邮箱
    	String subject = "由JavaMail发送";	//邮件主题
    	String text = "你好，这是一封来自SSM框架整合JavaMail的邮件";	//邮件正文
    	File file = new File("C:/Users/admin/Desktop/3.jpeg");	//发送一个文件
    	
    	@Test
    	public void testSend() {
    		
    		MimeMessage message = javaMailSender.createMimeMessage();	//创建邮件对象
    		MimeMessageHelper messageHelper;	//处理MimeMessage的辅助类
    		try {
    			messageHelper = new MimeMessageHelper(message, true);
    			messageHelper.setFrom(from);
    			messageHelper.setTo(to);
    			messageHelper.setSubject(subject);
    			messageHelper.setText(text,true);	//true代表支持html格式
    			
    			messageHelper.addAttachment(file.getName(), file);	//以附件形式发送一个文件
    			
    			javaMailSender.send(message);
    			System.out.println("success!");
    			
    		}catch (Exception e) {
    			e.printStackTrace();
    		}
    		
    	}
    	
    }

成功接收到发送的邮件
