java - Spring 独立应用程序 |记录

Question

我正在尝试将日志放入 spring 独立应用程序中。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

上面的代码日志工作正常。当我从主类中删除注释时，它不起作用。它在 log.out 文件中抛出一些附加信息，如下所示。让我知道它抛出这样的原因..？

日志仍在工作..在底部您可以看到

Exiting the program 
Exiting the program1

只有来自 Spring 框架的附加日志。当 spring 容器初始化时，它将记录自己的信息，如您在此处看到的。

我实际上看不出这里有什么问题。

<小时/>

如果您想删除 spring 日志记录，您可以在 log4j.properties 中指定特定包的日志记录级别，如下所示:

log4j.logger.org.springframework=WARN

应该只显示警告和错误。

我也会将您的 conversionPattern 更改为类似以下内容:%d{ABSOLUTE} %5p %c{1}:%L - %m%n

这将提供更多信息，您将能够看到哪个包正在记录什么
