Spring 启动,Tomcat 访问日志和打包应用程序中的 Logback 配置文件

Spring Boot, Tomcat Access Log with Logback config file in a packaged application

如何在 EmbeddedServletContainerCustomizer-Bean 中正确配置我的 LogbackValve 以读取 class 路径上的文件?

现在我有以下配置,它在我的本地主机上完美运行(logging.accessLogConfig: src/main/resources/logback_access_dev.xml 在 application.yml 中设置):

@Configuration
public class TomcatConfiguration {

@Value("${logging.accessLogConfig}")
private String accessLogConfig;

@Bean
public EmbeddedServletContainerCustomizer containerCustomizer() {
    return new EmbeddedServletContainerCustomizer() {
        @Override
        public void customize(ConfigurableEmbeddedServletContainer container) {
            if (container instanceof TomcatEmbeddedServletContainerFactory) {
                TomcatEmbeddedServletContainerFactory containerFactory =
                        (TomcatEmbeddedServletContainerFactory) container;

                LogbackValve logbackValve = new LogbackValve();
                logbackValve.setFilename(accessLogConfig);

                containerFactory.addContextValves(logbackValve);
            }
        }
    };
}

}

但是一旦我将它作为打包应用程序部署到我的服务器上,就再也找不到该文件了:-WARN in ch.qos.logback.access.tomcat.LogbackValve[] - [src/main/resources/logback_access_dev.xml] does not exist

我也在尝试更改 logging.accesslogConfig: classpath:logbook_access_dev.xml,并将内容读取到临时文件,但这也不起作用:

@Configuration
public class TomcatConfiguration {

private static final Logger logger = LoggerFactory.getLogger(TomcatConfiguration.class);

@Value("${logging.accessLogConfig}")
private Resource accessLogConfig;

@Bean
public EmbeddedServletContainerCustomizer containerCustomizer() {
    return new EmbeddedServletContainerCustomizer() {
        @Override
        public void customize(ConfigurableEmbeddedServletContainer container) {
            if (container instanceof TomcatEmbeddedServletContainerFactory) {
                TomcatEmbeddedServletContainerFactory containerFactory =
                        (TomcatEmbeddedServletContainerFactory) container;

                try {
                    InputStream configuration = accessLogConfig.getInputStream();
                    File configFile = File.createTempFile(accessLogConfig.getFilename(), "tmp");
                    FileUtils.copyInputStreamToFile(configuration, configFile);

                    LogbackValve logbackValve = new LogbackValve();
                    logbackValve.setFilename(configFile.getAbsolutePath());

                    containerFactory.addContextValves(logbackValve);
                }
                catch (IOException e) {
                    logger.warn("could not read access log configuration {}", accessLogConfig);
                }
            }
        }
    };
}

}

我正在使用 Spring Boot 1.2.7.RELEASE 和 logback-access 1.1.3.

非常感谢任何有关如何获得 运行 的帮助:)

现在通过创建我自己的 SpringLogbackValve 来解决问题,它接受 InputStream 而不是文件名。它基本上是 ch.qos.logback.access.tomcat.LogbackValve 的克隆,只是用 Inputstream inputStream 而不是 String fileName 和以下方法:

@Override
public void startInternal() throws LifecycleException {
    executorService = ExecutorServiceUtil.newExecutorService();

    if (inputStream != null) {
        try {
            JoranConfigurator jc = new JoranConfigurator();
            jc.setContext(this);
            jc.doConfigure(inputStream);
        }
        catch (JoranException e) {
            logger.warn("failed to configure {}", inputStream);
        }
    }
    else {
        getStatusManager().add(
                new WarnStatus("[" + inputStream + "] does not exist", this));
    }

    if (!quiet) {
        StatusPrinter.print(getStatusManager());
    }

    started = true;
    setState(LifecycleState.STARTING);
}
