How to solve the dynamic loading Agent warning issue during Springboot test?

Spring Boot Unit Test: Eliminate Dynamic Loading Agent Warning

When doing Spring Boot unit tests, you may encounter annoying dynamic loading Agent warnings:

 <code>warning: a java agent has been loaded dynamically warning: if a serviceability tool is in use, please run with -xx: enabledynamicagentloading to hide this warning warning: if a serviceability tool is not in use, please run with -djdk.instrument.traceusage for more information warning: dynamic loading of agents will be disallowed by default in a future release openjdk 64-bit server vm warning: sharing is only supported for boot loader classes because bootstrap classpath has been appended</code>

This warning indicates that your Java agent (Agent) is loaded dynamically and will be prohibited by default in future versions. You may have tried canceling the proxy detection of IDEA or adding -xshare:off and -xx: enabledynamicagentloading parameters, but it doesn't work well.

Here are some more effective solutions:

1. Correct configuration -xx: enabledynamicagentloading parameter: Make sure to add this parameter in the correct build configuration file. For example, in Gradle:

    test {
        jvmArgs('-xx: enableddynamicagentloading')
    }

   Or in Maven's surefire-plugin configuration:

   <plugin>
        <groupid>org.apache.maven.plugins</groupid>
        <artifactid>maven-surefire-plugin</artifactid>
        <configuration>
            <argline>-xx: enableddynamicagentloading</argline>
        </configuration>
    </plugin>

2. Use the -Djdk.instrument.traceUsage parameter: If it is determined that the service tool is not used, this parameter can provide more diagnostic information:

    test {
        jvmArgs('-Djdk.instrument.traceUsage')
    }

3. Check IDEA Run Configuration: Make sure that no agent-related conflicting configuration is set in the IDEA Run Configuration.

4. Upgrading the JDK version: Warning sometimes originates from JDK version issues, try to upgrade to the latest version.

5. Troubleshoot dependencies and plugins: Double-check project dependencies and plugins to find components that may dynamically load Java agents, consider disabling or removing them.

With the above method, you should be able to effectively resolve dynamic loading Agent warnings in Spring Boot unit tests.
