在项目中使用这套工具，main方法我注释掉，然后使用toSendMail（SendMailParam sendMailParam）。
这里定义的SendMailParam 为：
public class SendMailParam {
private String smtp;
private String username;
private String password;
private String from;//发送人
private String[] to;//接收人
// String[] copyto = {"909891736@qq.com"};
private String subject;//邮件主题
private String content;//邮件内容
private String filepath;//文件拿到的路径
public SendMailParam(){
this.smtp = "smtp.exmail.qq.com";//例子
this.username = "邮箱账号";
this.password = "邮箱密码";
this.from = "邮箱";
this.subject = "";
this.content = "";
this.filepath = "";
}
public String getSmtp() {
return smtp;
}
public void setSmtp(String smtp) {
this.smtp = smtp;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getFrom() {
return from;
}
public void setFrom(String from) {
this.from = from;
}
public String[] getTo() {
return to;
}
public void setTo(String[] to) {
this.to = to;
}
public String getSubject() {
return subject;
}
public void setSubject(String subject) {
this.subject = subject;
}
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
public String getFilepath() {
return filepath;
}
public void setFilepath(String filepath) {
this.filepath = filepath;
}
}
