Setting logback.xml path programmatically
提问by shabby
I know I can set the logback.xml path like this:
我知道我可以像这样设置 logback.xml 路径：
Specifying the location of the default configuration file as a system property
将默认配置文件的位置指定为系统属性
You may specify the location of the default configuration file with a system property named "logback.configurationFile". The value of this property can be a URL, a resource on the class path or a path to a file external to the application.
您可以使用名为“logback.configurationFile”的系统属性指定默认配置文件的位置。此属性的值可以是 URL、类路径上的资源或应用程序外部文件的路径。
java -Dlogback.configurationFile=/path/to/config.xml chapters.configuration.MyApp1
but how can I do it in code?
但我如何在代码中做到这一点？

You could use:
你可以使用：
System.setProperty("logback.configurationFile", "/path/to/config.xml");
But it would have to happen before logback is loaded, i.e. something like:
但它必须在加载 logback 之前发生，即：
class Main {
static { System.setProperty("logback.configurationFile", "/path/to/config.xml");}
private final Logger LOG = LoggerFactory.getLogger(Main.class);
public void main (String[] args) { ... }
}
Note: I have not tested it but it should work.
注意：我没有测试过它，但它应该可以工作。

LoggerContext loggerContext = (LoggerContext) LoggerFactory.getILoggerFactory();
loggerContext.reset();
JoranConfigurator configurator = new JoranConfigurator();
InputStream configStream = FileUtils.openInputStream(logbackPropertiesUserFile);
configurator.setContext(loggerContext);
configurator.doConfigure(configStream); // loads logback file
configStream.close();

modifying environment variables might not always be feasible. To do it properly see logback manual:
修改环境变量可能并不总是可行的。要正确执行此操作，请参阅 logback 手册：

I just want to share what I did in the end with a Jersey-Spring app:
我只想分享我最后用 Jersey-Spring 应用程序做了什么：
MyWebApplicationInitializer implements WebApplicationInitializer {
@Override
public void onStartup(final ServletContext servletContext) throws ServletException {
servletContext.addListener(new LogbackConfigListener());
try { LogbackConfigurer.initLogging(servletContext.getRealPath("/WEB-INF/logback.xml")); }
catch (FileNotFoundException | JoranException e) { e.printStackTrace(); }
}
}
I also have to add, that I had to move
我还必须补充一点，我必须搬家
<dependency>
<groupId>org.logback-extensions</groupId>
<artifactId>logback-ext-spring</artifactId>
<version>0.1.4</version>
<scope>compile</scope></dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-core</artifactId>
<version>1.2.3</version>
<scope>compile</scope></dependency>
from runtime (parent project in my case) to compile.
从运行时（在我的情况下为父项目）进行编译。

Include another logback xml to change path in logback-spring.xml
包含另一个 logback xml 以更改logback-spring.xml 中的路径
include resource = "/path/to/logback.xml"
包含资源 = "/path/to/logback.xml"
add data within includedtags in logback.xml
在logback.xml 中包含的标签中添加数据
