Aias00 opened a new issue, #6804:
URL: https://github.com/apache/shenyu/issues/6804
- severity: Medium
- files:
`shenyu-plugin-security/shenyu-plugin-sign/.../service/ComposableSignService.java:234-236`
(`String.format("%s-%s", PluginEnum.X.getName(), context.getRpcType())` inside
`skipSignExchange`, invoked from `handleExchange` on every sign-enabled request)
- description: Three `String.format` calls (Formatter + StringBuilder +
boxing) per signed request, when the module strings are static constants.
- impact: Per-signed-request allocation/boxing churn.
- suggested_fix: Precompute `private static final String SPRING_CLOUD_MODULE
= PluginEnum.SPRING_CLOUD.getName() + "-" + ...` constants, or compare enum
names directly without formatting.
- confidence: High
