To use the Spring Actuator loggers endpoint in a traditional Spring application (i.e., one that does not use Spring Boot), you will need to do the following:

Add the spring-actuator dependency to your application.

Configure the LoggersMvcEndpoint bean in your application context. This can be done by creating a configuration class that implements the ManagementConfigurer interface and overrides the configure method.
For example:

Copy code
@Configuration

We use a Socket Attaching Connector, which is enabled by default when the dt_socket transport is configured and the VM is running in the server debugging mode.

#Java Env Variable (Append $JAVA_OPTS or %JAVA_OPTS% if required)
JAVA_OPTS="-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005"

#For Java 9 or above
Since Java 9.0 JDWP supports only local connections by default, add*:<port> to listen all interfaces
java -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005 <AppJar>

#For java 1.5 to 1.8:
