Java Spring Boot

pluginagentmarketplace/custom-plugin-java

Covers the full Spring Boot stack from REST controllers to security configuration to JPA repositories. Generates proper SecurityFilterChain configs, sets up exception handlers with ProblemDetail, and includes Actuator monitoring endpoints. The examples show modern Spring Boot 3.x patterns like record-based DTOs and functional security configuration. Really useful when you need to spin up production-ready APIs quickly without hunting down boilerplate. The troubleshooting section alone saves time by covering the usual suspects like circular dependencies and security misconfigurations that always seem to trip people up.
