[AI-8th] 优化 DataPos RegisterId 使用 WordCache

[Amoteamame]

修复内容

• 问题：DataPos 中的 RegisterId 未使用 WordCache 进行优化，而其他字符串字段（如 dataInfoId、appName 等）都已使用 WordCache
• 解决方案：修改 BaseInfo.setRegisterId() 方法，使其使用 WordCache.getWordCache(registerId) 进行字符串优化
• 影响：减少内存使用，提高性能，特别是在处理大量数据时

技术细节

• 文件： server/common/model/src/main/java/com/alipay/sofa/registry/common/model/store/BaseInfo.java
• 修改：在 setRegisterId 方法中添加 WordCache 优化
• 原理：利用 Guava 的弱引用字符串池，有效复用相同的字符串对象，减少内存占用

📝 Walkthrough

Walkthrough

The setRegisterId(String) method in BaseInfo now applies WordCache interning to the registerId value before storage, ensuring consistency with other setter methods in the class that apply the same transformation for memory optimization.
