如何在PlantUML中调整组件右侧端口位置避免名称被遮挡？

使用PlantUML绘制架构图时，WebServer组件右侧的5个端口连线遮挡了组件名称，尝试调整端口位置但未成功。以下是当前使用的代码：

component "WebServer" as WS {
    port " " as P21
    port " " as P22
    port " " as P23
    port " " as P24
    port " " as P25

    component "Web-GUI" as WG {
        port " " as P11
        port " " as P12
        port " " as P13
        port " " as P14
        port " " as P15
    }
}



     ' Connections between ports
    P21 -right- P11
    P22 -right- P12
    P23 -right- P13
    P24 -right- P14
    P25 -right- P15

@enduml```

当前效果：WebServer组件的5个端口集中在右侧中间区域，连线直接穿过组件名称，导致名称被遮挡。
目标效果：WebServer组件的5个端口沿右侧垂直分布，连线从组件右侧边缘引出，不遮挡组件名称。

# 解决方案
可以通过指定端口的边缘位置，并调整连线逻辑来解决遮挡问题，以下是两种可行的修改方案：

## 方案一：将端口放在组件外部右侧
这种方式能清晰分离组件内部结构与外部端口，避免布局冲突：

```@startuml
left to right direction

component "WebServer" as WS {
    component "Web-GUI" as WG {
        port " " as P11
        port " " as P12
        port " " as P13
        port " " as P14
        port " " as P15
    }
}

' 把WebServer的端口定位在组件右侧，自动垂直排列
port " " as P21 on right of WS
port " " as P22 on right of WS
port " " as P23 on right of WS
port " " as P24 on right of WS
port " " as P25 on right of WS

' 连接端口，使用双向连线避免强制穿过多层组件
P21 -- P11
P22 -- P12
P23 -- P13
P24 -- P14
P25 -- P15
@enduml```

## 方案二：在组件内部指定端口位置
如果需要保持端口在组件内部的嵌套结构，可通过`on right`参数明确端口位置：

```@startuml
component "WebServer" as WS {
    ' 指定端口位于组件右侧边缘
    port " " as P21 on right
    port " " as P22 on right
    port " " as P23 on right
    port " " as P24 on right
    port " " as P25 on right

    component "Web-GUI" as WG {
        ' 对应指定Web-GUI的端口在左侧边缘
        port " " as P11 on left
        port " " as P12 on left
        port " " as P13 on left
        port " " as P14 on left
        port " " as P15 on left
    }
}

' 使用普通连线让PlantUML自动规划路径，避免穿过组件名称
P21 -- P11
P22 -- P12
P23 -- P13
P24 -- P14
P25 -- P15
@enduml```

**核心调整点**：
1. 用`on right`/`on left`指定端口的边缘位置，让端口沿组件垂直方向分布，不再集中在中间区域。
2. 移除`-right-`这类强制方向的连线语法，让PlantUML自动生成合理的连线路径，避免穿过组件名称。
