Parameter Passing Issues and Solutions in Debug Mode with Spring Boot Maven Plugin
This article delves into the problem where enabling debug mode (via jvmArguments parameter) in Spring Boot Maven plugin causes other custom parameters (e.g., server.port or path.to.config.dir) to become ineffective. It analyzes the root cause: the plugin's default activation of fork mode, which prevents command-line -D parameters from being properly passed. Based on best practices, two solutions are provided: first, passing all parameters uniformly through jvmArguments; second, using the correct prefix (e.g., spring-boot.run.jvmArguments) according to the Spring Boot version. Through detailed code examples and principle analysis, it helps developers fully understand and resolve this common configuration issue.
