我正在尝试将log登录到spring独立应用程序。这是我的代码
import org.apache.log4j.Logger;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.stereotype.Component;
@Component
public class Main {
static Logger log = Logger.getLogger(Main.class.getName());
public String id;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public static void main(String[] args) {
// ApplicationContext context = new ClassPathXmlApplicationContext("spring.xml");
log.debug("Going to create HelloWord Obj");
//Main p = (Main) context.getBean("hello");
//System.out.println(p.getId());
log.debug("Exiting the program");
log.debug("Exiting the program1");
}
}
我的log4j.properties是
log4j.rootLogger = DEBUG, FILE
# Define the file appender
log4j.appender.FILE=org.apache.log4j.FileAppender
log4j.appender.FILE.File=C://log.out
# Define the layout for file appender
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.conversionPattern=%m%n
在上面的代码日志工作正常。当我从主类删除注释时，它不工作。它在log.out文件中抛出一些额外的信息，如下所示。让我知道为什么它会像这样抛出..？

只有Spring框架的附加日志。初始化弹簧容器时，它将记录自己的信息，如您所见。
我实际上看不到任何问题。
如果要删除spring日志记录，可以在log4j.properties中指定特定包的日志记录级别：
log4j.logger.org.springframework=WARN
只应显示警告和错误。
我还会将您的conversionPattern更改为：%d{ABSOLUTE} %5p %c{1}:%L - %m%n
这将提供更多信息，您将能够看到哪些包正在记录什么
