Log4j以编程方式设置SMTP设置无法完全正常工作 [英] Log4j programmatically setting SMTP settings is not completely working

问题描述

我正在使用Log4j发送有关错误的电子邮件日志，并希望在java中的log4j中而不是在属性文件中设置SMTP设置.设置密码有效，我可以用它成功发送电子邮件

I'm using Log4j to send email logs on errors, and want to set the SMTP settings in log4j in java, and not in a properties file. Setting the password works, and i can successfully send an email with it

private static final Logger logger = Logger.getLogger("emailer");

(...)

Enumeration<?> enm = logger.getAllAppenders();
while (enm.hasMoreElements()) {
    Object element = enm.nextElement();
    if (element instanceof SMTPAppender) {
        ((SMTPAppender) element).setSMTPPassword(password);
    }
}

但是，在SMTPAppender中使用其他设置器没有任何作用(设置主机，用户名等)，log4j将继续使用属性文件的设置.

However, using the other setters in SMTPAppender does nothing ( setting host, username, etc. ), and log4j will keep using the properties file's settings.

(...)

log4j.logger.emailer=stdout, email
log4j.additivity.emailer=false

log4j.appender.email=org.apache.log4j.net.SMTPAppender
log4j.appender.email.SMTPHost=smtp.gmail.com
log4j.appender.email.SMTPPort=465
log4j.appender.email.SMTPUsername=[e-mail]
log4j.appender.email.SMTPPassword=-
log4j.appender.email.From=[e-mail]
log4j.appender.email.to=[e-mail]
log4j.appender.email.Subject=Error Alert
log4j.appender.email.layout=org.apache.log4j.PatternLayout
log4j.appender.email.layout.ConversionPattern=%d [%t] %-5p %c %x - %m%n
log4j.appender.email.BufferSize=10
log4j.appender.email.Threshold=ERROR

推荐答案

更改名称或密码后，您似乎需要调用activateOptions().

It looks like you need to call activateOptions() after you change the name or password.
