Description

System.out使用PrintStream， 会有synchronized锁，对性能可能有比较大的影响。即使不想添加其他依赖使用第三方的日志，也可以使用jdk自带的日志框架，java.util.logging。

Research direction
Search for all usages of System.out.println in the APIJSON source code, focusing on main source directories. Replace with java.util.logging.Logger instances, using appropriate log levels (e.g., FINE, INFO, WARNING). Ensure that logging configuration is added or updated. Test the application to confirm no functionality changes and that logs appear as expected. Refer to the existing code structure for consistent integration.
