使用spring实现邮件的发送实例(含测试,源码,注释)
此篇主要讲的是使用spring配置实现邮件发送,与之前的底层实现简便了不少,只需要几个配置就可以了,那么请往下看:
先写个接口
/** * @Title: IMailserdService.java * @Package org.service * @Description: TODO该方法的主要作用: * @author A18ccms A18ccms_gmail_com * @date 2017-5-30 上午10:36:34 * @version V1.0 */ package org.service; /** * * 项目名称:spring_Schop8 * 类名称:IMailserdService * 类描述: * 创建人:Mu Xiongxiong * 修改备注: * @version * */ public interface IMailsendService { /** * * @Title: sendMessage * @Description: 该方法的主要作用:发送邮件 * @param 设定文件 * @return 返回类型:void * @throws */ void sendMessage(); }
然后在写个实现该接口的类:
/** * @Title: AttMailsendServiceImpl.java * @Package org.service.impl * @Description: TODO该方法的主要作用: * @author A18ccms A18ccms_gmail_com * @date 2017-5-30 上午11:12:02 * @version V1.0 */ package org.service.impl; import java.io.IOException; import javax.mail.MessagingException; import javax.mail.internet.MimeMessage; import org.service.IMailsendService; import org.springframework.core.io.ClassPathResource; import org.springframework.mail.javamail.JavaMailSender; import org.springframework.mail.javamail.MimeMessageHelper; /** * * 项目名称:spring_Schop8 * 类名称:AttMailsendServiceImpl * 类描述: 使用spring实现对邮件的发送 * 创建人:Mu Xiongxiong * 修改备注: * @version * */ public class AttMailsendServiceImpl implements IMailsendService { private JavaMailSender javaMailSender; /**(非 Javadoc) * <p>Title: sendMessage</p> * <p>Description(描述):发送带附件的邮件 </p> * @see org.service.IMailsendService#sendMessage() */ @Override public void sendMessage() { MimeMessage message = javaMailSender.createMimeMessage(); MimeMessageHelper helper; try { helper = new MimeMessageHelper(message,true,"utf-8"); helper.setFrom("jerry@mail.com"); helper.setTo("tina@mail.com"); helper.setSubject("带附件的邮件"); //普通格式的 //helper.setText("发送一个附件内容!<a href='http://www.baidu.com'>百度搜索</a>"); //html格式的 helper.setText("发送一个附件内容!<a href='http://www.baidu.com'>百度搜索</a>",true); //添加附件1 ClassPathResource file1 = new ClassPathResource("/org/doc/doc.txt"); helper.addAttachment(file1.getFilename(),file1.getFile()); //添加附件2 ClassPathResource file2 = new ClassPathResource("/org/doc/text.txt"); helper.addAttachment(file2.getFilename(), file2.getFile()); javaMailSender.send(message); } catch (MessagingException e) { // TODO 异常执行块! e.printStackTrace(); } catch (IOException e) { // TODO 异常执行块! e.printStackTrace(); } } public JavaMailSender getJavaMailSender() { return javaMailSender; } public void setJavaMailSender(JavaMailSender javaMailSender) { this.javaMailSender = javaMailSender; } }
上面的这个类还可以发送带附件的邮件,里面含两个附件(文件),我弄上来吧:
还有一种是使用模板发送带html格式的邮件:
我直接上实现类:
/** * @Title: CreateMatterServiceImpl.java * @Package org.service.impl * @Description: TODO该方法的主要作用: * @author A18ccms A18ccms_gmail_com * @date 2017-5-30 上午11:46:53 * @version V1.0 */ package org.service.impl; import java.io.IOException; import java.util.HashMap; import java.util.Map; import javax.mail.MessagingException; import javax.mail.internet.MimeMessage; import org.service.IMailsendService; import org.springframework.mail.javamail.JavaMailSender; import org.springframework.mail.javamail.MimeMessageHelper; import org.springframework.ui.freemarker.FreeMarkerTemplateUtils; import freemarker.template.Configuration; import freemarker.template.Template; import freemarker.template.TemplateException; /** * * 项目名称:spring_Schop8 * 类名称:CreateMatterServiceImpl * 类描述: * 创建人:Mu Xiongxiong * 修改备注: * @version * */ public class CreateMatterServiceImpl implements IMailsendService { private JavaMailSender javaMailSender; private Configuration configuration; /**(非 Javadoc) * <p>Title: sendMessage</p> * <p>Description(描述):使用后模板发送邮件 </p> * @see org.service.IMailsendService#sendMessage() */ @Override public void sendMessage() { MimeMessage message = javaMailSender.createMimeMessage(); try { MimeMessageHelper helper = new MimeMessageHelper(message,true,"UTF-8"); helper.setFrom("jerry@mail.com"); helper.setTo("tina@mail.com"); helper.setSubject("使用模板进行发送邮件"); helper.setText(getText(),true); //从模板里面读取 javaMailSender.send(message); } catch (MessagingException e) { // TODO 异常执行块! e.printStackTrace(); } } //读取模板 private String getText(){ String txt = ""; try { Template template = configuration.getTemplate("mail.ftl"); //通过map传递动态数据 Map map = new HashMap(); map.put("username","雄雄"); //解析模板文件 txt = FreeMarkerTemplateUtils.processTemplateIntoString(template,map); } catch (IOException e) { // TODO 异常执行块! e.printStackTrace(); } catch (TemplateException e) { // TODO 异常执行块! e.printStackTrace(); } return txt; } public JavaMailSender getJavaMailSender() { return javaMailSender; } public void setJavaMailSender(JavaMailSender javaMailSender) { this.javaMailSender = javaMailSender; } public Configuration getConfiguration() { return configuration; } public void setConfiguration(Configuration configuration) { this.configuration = configuration; } }
模板文件如下:
然后在看看spring里面是怎么配置的呢?
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd"> <bean id="mailsender" class="org.springframework.mail.javamail.JavaMailSenderImpl"> <property name="host" value="mail.com"></property> <property name="port" value="25"></property> <property name="username" value="jerry"></property> <property name="password" value="123" ></property> <property name="protocol" value="smtp"></property> <property name="defaultEncoding" value="utf-8"></property> <property name="javaMailProperties"> <props> <prop key="mail.smtp.auth">true</prop> </props> </property> </bean> <!-- 配置FreeMarker--> <bean id="freeMarkerConfiguration" class="org.springframework.ui.freemarker.FreeMarkerConfigurationFactoryBean"> <!-- 指定模板文件路径 --> <property name="templateLoaderPath" value="org/doc/"></property> <!-- 设置freekMarker环境变量 --> <property name="freemarkerSettings"> <props> <prop key="default_encoding">UTF-8</prop> </props> </property> </bean> <!-- 简单邮件 --> <bean id="simpleMailsendService" class="org.service.impl.SimpleMailsendServiceImpl"> <property name="sender" ref="mailsender"></property> </bean> <!-- html和带附件的邮件 --> <bean id="AttMailsendService" class="org.service.impl.AttMailsendServiceImpl"> <property name="javaMailSender" ref="mailsender"></property> </bean> <!-- 使用模板发送邮件--> <bean id="createMatterService" class="org.service.impl.CreateMatterServiceImpl"> <property name="configuration" ref="freeMarkerConfiguration"></property> <property name="javaMailSender" ref="mailsender"></property> </bean> </beans>
当前时间已经是00点多了,又累又困,我就不详细解释这个applicationContexct.xml里面的内容了,里面有注释,看不懂的可以评论,我第一时间改进!
接着我们测试一下:
TestMail:
package org.test; import org.junit.Test; import org.service.IMailsendService; import org.service.impl.Mail; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class TestMail { @Test public void testMail() { ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml"); //简单邮件 //IMailsendService mailsendService=(IMailsendService) ctx.getBean("simpleMailsendService"); //复杂邮件 //IMailsendService mailsendService=(IMailsendService) ctx.getBean("AttMailsendService"); //使用模板的文件 IMailsendService mailsendService=(IMailsendService) ctx.getBean("createMatterService"); mailsendService.sendMessage(); System.out.println("发送成功!"); } }
注明一下:简单邮件是直接发的文本内容,复杂邮件是包含html格式和附件的,模板发送是html格式的另一种方式,我们来看看运行的结果:
先看看带附件,还有html格式的邮件:
接下来是简单邮件:
接下来的一种是使用模板发送邮件,用户名是动态上去的:
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持我们。
