java - 如何以编程方式设置 Spring log4j 属性文件路径

Question

我就是这样使用spring-boot的；

public static void main(String[] args) throws Exception {

        ApplicationContext context = new AnnotationConfigApplicationContext(SpringConfiguration.class);

////

@Configuration
@ComponentScan("com.mycompnay")
@PropertySources({
        @PropertySource("classpath:application.properties")})

public class SpringConfiguration {


    @Bean
    public static PropertySourcesPlaceholderConfigurer propertyPlaceholderConfigurer() {
        return new PropertySourcesPlaceholderConfigurer();
    }

我想了解如何以这种方式设置 log4j.properties 文件？我找到了一种使用 application.properties 来做到这一点的方法。但我们如何以编程方式为 log4j.properties 设置它？

log4j.properties

log4j.rootLogger=INFO, console

log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.conversionPattern=%d %p [%c] - <%m>%n

#Debug logging
log4j.appender.DebugAppender=org.apache.log4j.RollingFileAppender
log4j.appender.DebugAppender.Threshold=DEBUG
log4j.appender.DebugAppender.File=vertx.log
log4j.appender.DebugAppender.MaxFileSize=200KB
log4j.appender.DebugAppender.MaxBackupIndex=5
log4j.appender.DebugAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.DebugAppender.layout.ConversionPattern=%d %p [%c] - <%m>%n

log4j.logger.org.springframework=ERROR,console
log4j.logger.org.apache=ERROR,console

但是在控制台上我仍然看到这样的日志记录:

13:41:59.525 [main] DEBUG o.s.core.env.StandardEnvironment - Adding [systemProperties] PropertySource with lowest search precedence

添加了 log4j 调试。控制台输出:

谢谢，射线。

我通过将此参数添加到可执行 jar 来修复它:

-Dlog4j.configurationFile=file:/path.to/log4j.properties
