Java Dev

This is a comprehensive Java development guide that enforces Google and Alibaba style conventions with some hard rules that'll save you from production fires. It mandates Lombok for all DTOs (no hand-written getters), caps IN clauses at 500 parameters with batch utilities, and blocks read-modify-write patterns in favor of atomic SQL updates. The N+1 query section alone is worth it, showing exactly how to refactor forEach repository calls into batch queries with Maps. Spring Boot 3.x gets special attention around constructor injection and circular dependency traps when extracting services. There's also auth filter degradation rules and 0-based pagination alignment across the stack. It's opinionated in the right places, like refusing partial credentials that give worse UX than anonymous access.
