手把手教你 ，spring定时发送邮件
我这里只是一个简单的例子，也是在网上找到的一个邮件发送的例子，然后自己修改成了quartz定时发送，下面有源代码大家可以下载，可以根据需要进行修改。
第一步：建立一个web Project
加入必须的包 到lib中
activation-1.1.jar
mail-1.4.jar
commons-collections-3.2.jar
commons-lang-2.5.jar
commons-logging-1.1.jar
quartz-1.6.1.jar
spring-2.5.jar
spring-context-support-2.5.6.jar
spring-web-2.5.6.jar
velocity-1.6.4.jar
最好不要用myeclipse自带的包，可能会有冲突。
第二步：配置web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
我这里applicationContext.xml就直接放在了classpath下
文件目录如图：
第三步：加入所需要的配置文件
applicationContext.xml ：
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jee="http://www.springframework.org/schema/jee"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-2.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"
xmlns:tx="http://www.springframework.org/schema/tx">

mail.properties ：
修改成你的邮箱吧，注意哦。邮箱设置里面要:开启POP3/SMTP服务
如：qq邮箱-->邮箱设置-->账户-->POP3/IMAP/SMTP服务-->开启POP3/SMTP服务
[email protected] mail.host=smtp.qq.com mail.password=youPassword mail.smtp.auth=true mail.smtp.timeout=25000 mail.username=youUserName
log4j.properties (根据你的需要添加，也 可以不要) :
log4j.rootLogger=info, A1,logfile
#log4j.rootLogger=INFO,A1,R
# ConsoleAppender
log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} [%F:%L] [%p] - %m%n
##logfile
log4j.appender.logfile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.logfile.File=${catalina.base}/logs/proj.log
log4j.appender.logfile.DatePattern='_'yyyyMMdd'.log'
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} [%F:%L] [%p] - %m%n
第四步：编写邮件发送器
package com.ryt.mail;
import java.util.Map;
import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.apache.velocity.app.VelocityEngine;
import org.apache.velocity.exception.VelocityException;
import org.springframework.core.io.ClassPathResource;
import org.springframework.mail.MailException;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.ui.velocity.VelocityEngineUtils;
/**
* 邮件发送器
*/
public class MailUtil {
protected final Log log = LogFactory.getLog(getClass());
private JavaMailSender javaMailSender;
private VelocityEngine velocityEngine;
private String from;
private String title;
private String encoding;
private String templateLocation;
private String[] toEmails;
private Map<String,String> model;
public boolean send(){
try {
MimeMessage msg = javaMailSender.createMimeMessage();
MimeMessageHelper message = new MimeMessageHelper(msg, true, "UTF-8");
message.setFrom(from);
message.setSubject(title);
message.setTo(toEmails);
message.setText(getMessage(), true); // 如果发的不是html内容去掉true参数
message.addAttachment("testMyImg.gif", new ClassPathResource("doc/myImg.gif"));
// message.addAttachment("Erlang-ch.pdf", new ClassPathResource("doc/Erlang-ch.pdf")); //添加附件
// message.addInline("myLogo.gif",new ClassPathResource("doc/myImg.gif"));
// System.out.println(System.getProperty("java.class.path"));
javaMailSender.send(msg);
} catch (MessagingException e) {
e.printStackTrace();
if(log.isWarnEnabled()) {
log.warn("邮件信息导常! 邮件标题为: "+title);
}
return false;
} catch (MailException me) {
me.printStackTrace();
if(log.isWarnEnabled()) {
log.warn("发送邮件失败! 邮件标题为: "+title);
}
return false;
}
return true;
}
/**
* 邮件模板中得到信息
* @return 返回特发送的内容
*/
private String getMessage() {
try {
return VelocityEngineUtils.mergeTemplateIntoString(velocityEngine, templateLocation, encoding, model);
} catch (VelocityException e) {
e.printStackTrace();
log.error("邮件模板读取失败!邮件标题为: "+title);
}
return "";
}
private String[] createToEmail(String to) {
return new String[] {to};
}
public void setToEmail(String to) {
setToEmails(createToEmail(to));
}
public void setJavaMailSender(JavaMailSender javaMailSender) {
this.javaMailSender = javaMailSender;
}
public void setVelocityEngine(VelocityEngine velocityEngine) {
this.velocityEngine = velocityEngine;
}
public void setEncoding(String encoding) {
this.encoding = encoding;
}
public void setModel(Map<String,String> model) {
this.model = model;
}
public void setTemplateLocation(String templateLocation) {
this.templateLocation = templateLocation;
}
public void setTitle(String title) {
this.title = title;
}
public void setToEmails(String[] toEmails) {
this.toEmails = toEmails;
}
public void setFrom(String from) {
this.from = from;
}
public String getTemplateLocation() {
return templateLocation;
}
}
写一个Velocity模板hello.vm：放在velocity下
${username}，您好，欢迎来到<a href="http://i.firefoxchina.cn/" target="_blank">欢迎来到firfox</a>！
接下来 测试一下吧
public class TestMailSend {
public static void main(String[] args) {
MailUtil mailUtil = (MailUtil) new ClassPathXmlApplicationContext("applicationContext.xml").getBean("mailUtil");
Map<String, String> data = new HashMap<String, String>();
data.put("username", "mir liu");
mailUtil.setTemplateLocation("hello.vm");
mailUtil.setModel(data);
mailUtil.setToEmail("[email protected]");
mailUtil.setTitle("mail with veloctiy and spring");
System.out.println("发送中请等待.....");
mailUtil.send();
System.out.println("发送成功.....");
}
}
测试通过的话我们接下来就开始写quartz 触发器调用的类了：
package com.ryt.mail;
import java.util.HashMap;
import java.util.Map;
public class MailManager {
MailUtil mailUtil;
public void setMailUtil(MailUtil mailUtil) {
this.mailUtil = mailUtil;
}
public void sendMail(){
Map<String, String> data = new HashMap<String, String>();
data.put("username", "mir liu");
mailUtil.setTemplateLocation("hello.vm");
mailUtil.setModel(data);
mailUtil.setToEmail("[email protected]");
mailUtil.setTitle("auto send mail with veloctiy and spring!!!");
boolean isSuccess=mailUtil.send();
if(isSuccess)
System.out.println("quartz 发送成功.....");
else
System.out.println("发送失败!!!");
}
}
那么这个怎么测试呢？把这个部分改成你电脑 马上要到的时间
<property name="cronExpression" value="0 0 12 * * ?" />
这个是Quartz的cron表达式 ，该怎么改还是baidu一下吧
所有环节都完成。
