Lessons Learned from Upgrading Thymeleaf
summary
Broadleaf upgrades Thymeleaf 2 → 3 to use first-class fragment parameters and drops XML parsing for an auto HTML parser, yielding measurable speedups and full HTML5 support. About 60–70 custom processors get rewritten to the new modular processor APIs; a compatibility layer and Spring resource template resolver let one codebase run both versions. Watch out for self-closing tag behavior (self-closing divs break rendering) and for global variables set inside processors—those must move to request scope or be redesigned. Overall migration mostly succeeds.
