Java发送邮件
因为工作需要发送邮件。所以上网找了例子，整理了一下发表出来，方便有需要的朋友。
封装邮件信息的一个实体类。
package com.base.myproject.mail;
import java.util.ArrayList;
import java.util.List;
import java.util.Properties;
public class MailSenderInfo {
public static String TEXT = "text/plain;charset=gb2312";
public static String HTML = "text/html;charset=gb2312";
private String mailServerHost; // 发送邮件的服务器的IP和端口
private String mailServerPort = "25";
private String fromAddress; // 邮件发送者的地址
private String toAddress; // 邮件接收者的地址
private String userName;
private String password; // 登陆邮件发送服务器的用户名和密码
private boolean validate = false; // 是否需要身份验证
private String subject; // 邮件主题
private String content; // 邮件的文本内容
private List<Object> attaches = new ArrayList<Object>(); //邮件附件;
private String cc; //抄送邮件给某人
private String bc; //隐蔽副本 隐蔽抄送给某人
/**
* 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 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;
}
public List<Object> getAttaches() {
return attaches;
}
public void setAttaches(List<Object> attaches) {
this.attaches = attaches;
}
public String getCc() {
return cc;
}
public void setCc(String cc) {
this.cc = cc;
}
public String getBc() {
return bc;
}
public void setBc(String bc) {
this.bc = bc;
}
}
邮件用户名密码认证
package com.base.myproject.mail;
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
public class MyAuthenticator extends Authenticator{
String userName = null;
String password = null;
public MyAuthenticator(){
}
public MyAuthenticator(String username, String password) {
this.userName = username;
this.password = password;
}
protected PasswordAuthentication getPasswordAuthentication(){
return new PasswordAuthentication(userName, password);
}
}
