I have a spring-boot project where I want to enable loadTimeWeaving for entityManagerFactory.

I know that I can create a bean of InstrumentationLoadTimeWeaver like below.

@Bean
public LoadTimeWeaver loadTimeWeaver() {
    return new InstrumentationLoadTimeWeaver();
}

and it works well when I add --javaagent:<path-to-spring-instrument.jar>.

Command

java --javaagent:~/.m2/repository/org/springframework/spring-instrument/<version>/spring-instrument-<version>.jar -jar myjar.jar

There are two problems with the above approach-

1. I have to hardcode the version managed by spring-boot-starter-parent.
2. Adding javaagent at multiple deploy scripts as well as IDE config.

I came across agent-embedder-maven-plugin where I can embed javaagent as below.

<plugin>
    <groupId>dev.aspectj</groupId>
    <artifactId>agent-embedder-maven-plugin</artifactId>
    <version>1.0</version>
    <executions>
        <execution>
            <id>embed-agent</id>
            <goals>
                 <goal>embed</goal>
            </goals>
            <configuration>
                 <javaAgents>
                      <agent>
                          <groupId>org.springframework</groupId>
                          <artifactId>spring-instrument</artifactId>
                      </agent>
                  </javaAgents>
            </configuration>
        </execution>
    </executions>
</plugin>

But it doesn’t work while running the tests and I have to manage two configs

1. Explicitly use javaagent for test
2. Use plugin for executing jar for deployment

How can I use agent-embedder-maven-plugin for running tests as well?

Currently, I am running test by adding configuration to surefire plugin like below –

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>3.2.3</version>
    <configuration>
        <argLine>
            --add-opens java.base/java.lang=ALL-UNNAMED
            -javaagent:${user.home}/.m2/repository/org/springframework/spring-instrument/${spring-instrument.version}/spring-instrument-${spring-instrument.version}.jar
        </argLine>
    </configuration>
</plugin>
