java mail发送邮件
最近做测试的时候，需要发送邮件，但是实际的邮件收件人，必须是测试或开发，不想每次都改收件人。
所以自己重新写了个发送邮件程序：
1.收件人默认配置开发或者测试；
2.调用的实时发送邮件接口，会实时发送，提高测试效率；
3.收件人，抄送人，密送人会在邮件标题里面列出来，方便测试检查。
后期增加附件的发送。
认证类
package com.info.util; import javax.mail.Authenticator; import javax.mail.PasswordAuthentication; /** * 邮件 * 自定义认证器 * @author menghu * */ 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); } }
自定义邮件对象
package com.info.util; /** * * 邮件 * 发送邮件工具类 * */ 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; // 邮件发送者的地址 private String fromAddress; // 邮件接收者的地址 private String toAddress; // 邮件抄送者的地址 private String ccAddress; // 邮件密送者的地址 private String bccAddress; // 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; } public String getCcAddress() { return ccAddress; } public void setCcAddress(String ccAddress) { this.ccAddress = ccAddress; } public String getBccAddress() { return bccAddress; } public void setBccAddress(String bccAddress) { this.bccAddress = bccAddress; } }
