how to use the variable ${variable} which defined in application.yml in log4j2.xml - spring

I encountered the same problem as ApplicationListeners between ConfigFileApplicationListener and LoggingApplicationListener, the purpose is to use the variable ${variable} which defined in application.yml in log4j2.xml.But in the spring boot 2.0 uses log4j2, the LoggingApplicationListener order is still before the ConfigFileApplicationListener.

Weblogic fails deploying SpringBoot + Security Extensions (BEA-160228: AppMerge failed to merge your application)

I'm having trouble adding some dependencies to my Spring Boot application:
I have a Spring Boot (2.0.4.RELEASE) application. Weblogic deploy the application perfectly.
I have added some dependencies in order to develop a SAML2 Client (based on this example)
With this dependencies, I get the following error. In the server's log: <BEA-160228> <AppMerge failed to merge your application. If you are running AppMerge on the command-line, merge again with the -verbose option for more details. See the error message(s) below.>
Of all the dependencies, I have isolated the one that generates the problem, it is:
<groupId>org.springframework.security.extensions</groupId>
<artifactId>spring-security-saml2-core</artifactId>
<version>1.0.10.RELEASE</version>

info.app.name: xxx
I think spring.datasource.maximum-pool-size=2 is not sufficient. What should I add to the properties file? Should I maybe exclude HikariCP from my pom file?

Since Spring Boot 2.0, Hikari is the default DataSource implementation. Therefore, if you want to configure the maximumPoolSize (a parameter for Hikeri Configuration) in Spring Boot, you are supposed to set it as follows:
For application.properties
spring.datasource.hikari.maximum-pool-size=2
For application.yml
spring:
datasource:
hikari:
maximum-pool-size: 2

If you haven't changed the connection implementation pool that Spring is using, it should be HikariCP, and then the setting you're looking for is:
spring.datasource.hikari.maximum-pool-size
its listed here: https://docs.spring.io/spring-boot/docs/current/reference/html/appendix-application-properties.html

Spring Boot - excluding log4j2 library doesn't work

I got BIG problem with excluding one path which is leading to log4j library. I used solution from Spring documentation, but it doesn't work for me. I did something like this:
<dependency>

But still - it doesn't work...
Here is an error:

Additionally - if I won't exclude ch.qos.logback then Spring Boot also will be screaming that he found another binding
