让PlantUML的布线更加简洁的一个方法

• 比如这样的代码：

@startuml 系统架构图
title IntelliJ IDEA AI编程助教插件 - 系统架构图
package "AI编程助教插件" {package "表示层 (Presentation Layer)" {[Tool Window] as ToolWindow[Editor Actions] as EditorActions}package "应用层 (Application Layer)" {[TaToolWindowPanel] as ChatService[AskSelectedCodeAction\nCodeRefactorAction] as CodeModificationService}package "领域层 (Domain Layer)" {[SimpleRetriever] as RAGEngine[DocumentIndexer] as KnowledgeBaseManager[ContextAwareProcessor] as ContextAnalyzer[OpenRouterClient] as LLMEngine}package "基础设施层 (Infrastructure Layer)" {[Apache Tika] as DocParser[VectorStore] as VectorStore[SimpleRetriever] as RetrievalEngine}package "工具类" {[IndexFileManager] as IndexFileManager}
}package "外部系统" {[Course Documents] as CourseDocs[Large Language Model] as LLM
}/' 层间关系 '/
ToolWindow --> ChatService : 用户提问
EditorActions --> CodeModificationService : 代码操作请求ChatService --> RAGEngine : 触发检索流程
CodeModificationService --> ContextAnalyzer : 获取代码上下文
CodeModificationService --> LLMEngine : 调用大语言模型RAGEngine --> KnowledgeBaseManager : 查询知识库
KnowledgeBaseManager --> RetrievalEngine : 检索相关文档
KnowledgeBaseManager --> DocParser : 解析课程文档
KnowledgeBaseManager --> VectorStore : 存储/检索向量LLMEngine --> LLM : 调用大语言模型VectorStore --> RetrievalEngine : 提供向量检索
RetrievalEngine --> RAGEngine : 返回检索结果DocParser --> CourseDocs : 读取课程文档/' 数据存储 '/
folder "数据存储" {[Index File] as IndexFile[Vector Database] as VectorDB
}IndexFileManager --> IndexFile : 管理文档索引路径
VectorDB --> VectorStore : 存储向量数据@enduml

• 图的效果是这样的：

• 布线很乱

解决方法

• 在@startuml下方添加skinparam linetype ortho设置布线为直线

• skinparam defaultFontSize 12调小字体大小
  skinparam Padding 20调大元素间距

• 图的效果：

• 好像没有整齐多少, 但是线变直了!
