How use properties from nacos config in logback.xml ?

[Astronaut-K]

I have logback config xml in springcloud project(Using nacos config & discovery v1.1.3).Then I set some datasource properties in logback-development.xml(These properties are store in nacos). But the log appender print error that properties are null when I run application.

logback-development.xml:

<appender name="redis_out" ....
.......
  <host>${LOG_REDIS_HOST}</host>
 <port>${LOG_REDIS_PORT}</port>
......
  <pattern>
 {  "app": "${spring.application.name}",
    "timestamp": "%d{yyyy-MM-dd'T'HH:mm:ss.SSSZZ}",
......
 </appender>

The log appender print error like this : [{"app":"spring.application.name_IS_UNDEFINED",......

It seems like properties are not active when log appender init.
