mail.smtp.socketFactory.port=465
mail.smtp.socketFactory.fallback=false
mail.recipient.cc=[e-mail]

配置类

@Component
public class AppConfig 
    // mail
	@Value("$mail.smtp.host")
	private String mailHost;
	@Value("$mail.smtp.user")
	private String mailUser;

	@Value("$mail.smtp.port")
	private String mailPort;
	@Value("$mail.smtp.auth")
	private String mailAuth;
	@Value("$mail.smtp.timeout")
	private String mailTimeout;
	@Value("$mail.smtp.ssl.enable")
	private String mailSsl;
	@Value("$mail.recipient.cc")
	private String mailCc;

    public String getMailHost() 
		return mailHost;
	

	public void setMailHost(String mailHost) 
		this.mailHost = mailHost;
	

	public String getMailUser() 
		return mailUser;
	

	public void setMailUser(String mailUser) 
		this.mailUser = mailUser;
	

	public String getMailPassword() 
		return mailPassword;
	

	public void setMailPassword(String mailPassword)
