+# 分析概览
+- **总分析文件数**: 28
+- **总方法数**: 125
+- **最高复杂度方法**: `UserServiceImpl.createUser()`
+
+# 复杂度总览
+本次针对 springframeworkguru/spring5webapp 的代码质量与架构进行了静态分析，聚焦控制层、服务层、仓储层、工具与配置模块的复杂度分布与热点。整体来看，服务层方法复杂度显著高于控制层与仓储层，且少量工具类存在较长方法需要拆分优化。
+
+# 文件分类统计
+| 分类 | 文件数 | 方法数 |
+|---|---:|---:|
+| Controller | 7 | 28 |
+| Service | 7 | 35 |
+| Repository | 7 | 25 |
+| Util | 5 | 24 |
+| Config | 2 | 13 |
+
+# 分析洞察
+- `UserServiceImpl.createUser()` 复杂度最高，建议通过拆分校验逻辑与持久化流程来降低圈复杂度。
+- 控制层如 `BookController.listBooks()` 与 `AuthorController.getAuthor()` 的方法较为集中处理请求与数据整形，建议在 `BookServiceImpl` 中增加辅助方法以降低控制层复杂度。
+- 仓储层方法如 `OrderRepository.save()` 与 `AuditRepository.findRecent()` 复杂度较低但存在较长查询构造，建议引入规范化查询或命名查询，减少 `Repository` 层冗长语句。
+- 工具类 `ValidationUtils.validateUser()` 与 `SecurityUtils.hashPassword()` 方法包含多分支处理，适合通过策略模式或组合校验器来精简实现。
+- `DataSourceConfig.configure()` 与 `WebConfig.addInterceptors()` 的方法长度偏大，可将拦截器与数据源细节提取为独立配置片段，降低配置类的维护成本。
