java中发邮件代码 java实现发送邮件功能( 四 )

IT技术设置


message.setSubject(title);//设置邮件标题
message.setText(content);//设置邮件正文
message.setSentDate(new Date()); //设置邮件日期
message.saveChanges();//保存邮件更改信息
Transport transport = s.getTransport("smtp");
transport.connect("smtp.qq.com", "451144426", "密码"); //服务器地址，邮箱账号，邮箱密码
transport.sendMessage(message, message.getAllRecipients());//发送邮件
transport.close();//关闭
}
catch (Exception e)
{
e.printStackTrace();
flag = false;//发送失败
}
return flag;
}
这是一个javaMail的邮件发送代码，需要一个mail.jar
java 怎么实现发送邮件例子第一个类：MailSenderInfo.java
[java] view plain copy
package com.util.mail;
/**
* 发送邮件需要使用的基本信息
*author by wangfun
小说520
*/
import java.util.Properties;
public class MailSenderInfo {
// 发送邮件的服务器的IP和端口
private String mailServerHost;
private String mailServerPort = "25";
// 邮件发送者的地址
private String fromAddress;
// 邮件接收者的地址
private String toAddress;
// 登陆邮件发送服务器的用户名和密码
private String userName;
private String password;
// 是否需要身份验证
private boolean validate = false;
// 邮件主题
private String subject;
// 邮件的文本内容
private String content;
// 邮件附件的文件名
private String[] attachFileNames;
/**
* 获得邮件会话属性
*/
public Properties getProperties(){
Properties p = new Properties();
p.put("mail.smtp.host", this.mailServerHost);
p.put("mail.smtp.port", this.mailServerPort);
p.put("mail.smtp.auth", validate ? "true" : "false");
return p;
}
public String getMailServerHost() {
return mailServerHost;
}
public void setMailServerHost(String mailServerHost) {
this.mailServerHost = mailServerHost;
}
public String getMailServerPort() {
return mailServerPort;
}
public void setMailServerPort(String mailServerPort) {
this.mailServerPort = mailServerPort;
}
public boolean isValidate() {
return validate;
}
public void setValidate(boolean validate) {
this.validate = validate;
}
public String[] getAttachFileNames() {
return attachFileNames;
}
public void setAttachFileNames(String[] fileNames) {
this.attachFileNames = fileNames;
}
public String getFromAddress() {
return fromAddress;
}
public void setFromAddress(String fromAddress) {
this.fromAddress = fromAddress;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getToAddress() {
return toAddress;
}
public void setToAddress(String toAddress) {
this.toAddress = toAddress;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getSubject() {
return subject;
}
public void setSubject(String subject) {
this.subject = subject;
}
public String getContent() {
return content;
}
public void setContent(String textContent) {
this.content = textContent;
}
}
第二个类：SimpleMailSender.java
[java] view plain copy
package com.util.mail;
import java.util.Date;
import java.util.Properties;
import javax.mail.Address;
import javax.mail.BodyPart;
import javax.mail.Message;
import javax.mail.MessagingException;
