篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了分析工厂采购系统,画出顺序图相关的知识,希望对你有一定的参考价值。
第一部分:顺序图语法
(1)简单示例:你可以用->
来绘制参与者之间传递的消息, 而不必显式地声明参与者。你也可以使用 -->
绘制一个虚线箭头。另外,你还能用 <-
和 <--
,这不影响绘图,但可以提高可读性。 注意:仅适用于时序图,对于其它示意图,规则是不同的。
1 @startuml 2 Alice -> Bob: Authentication Request 3 Bob --> Alice: Authentication Response 4 5 Alice -> Bob: Another authentication Request 6 Alice <-- Bob: another authentication Response 7 @enduml
(2)声明参与者:关键字 participant
用于改变参与者的先后顺序。
你也可以使用其它关键字来声明参与者:
actor
boundary
control
entity
database
1 @startuml 2 actor Foo1 3 boundary Foo2 4 control Foo3 5 entity Foo4 6 database Foo5 7 collections Foo6 8 Foo1 -> Foo2 : To boundary 9 Foo1 -> Foo3 : To control 10 Foo1 -> Foo4 : To entity 11 Foo1 -> Foo5 : To database 12 Foo1 -> Foo6 : To collections 13 14 @enduml
1 @startuml 2 actor Bob #red 3 ‘ The only difference between actor 4 ‘and participant is the drawing 5 participant Alice 6 participant "I have a really\\nlong name" as L #99FF99 7 /‘ You can also declare: 8 participant L as "I have a really\\nlong name" #99FF99 9 ‘/ 10 11 Alice->Bob: Authentication Request 12 Bob->Alice: Authentication Response 13 Bob->L: Log transaction 14 @enduml
您可以使用关键字 order
自定义顺序来打印参与者。
1 @startuml 2 participant Last order 30 3 participant Middle order 20 4 participant First order 10 5 @enduml
(3)在参与者中使用非字母符号:你可以使用引号定义参与者,还可以用关键字 as
给参与者定义别名。
1 @startuml 2 Alice -> "Bob()" : Hello 3 "Bob()" -> "This is very\\nlong" as Long 4 ‘ You can also declare: 5 ‘ "Bob()" -> Long as "This is very\\nlong" 6 Long --> "Bob()" : ok 7 @enduml
(4)给自己发消息:参与者可以给自己发信息,消息文字可以用\\n
来换行。
1 @startuml 2 Alice->Alice: This is a signal to self.\\nIt also demonstrates\\nmultiline \\ntext 3 @enduml
(5)修改箭头样式:修改箭头样式的方式有以下几种:
- 表示一条丢失的消息:末尾加
x
- 让箭头只有上半部分或者下半部分:将
<
和>
替换成\\
或者/
- 细箭头:将箭头标记写两次 (如
>>
或//
) - 虚线箭头:用
--
替代-
- 箭头末尾加圈:
->o
- 双向箭头:
<->
1 @startuml 2 Bob ->x Alice 3 Bob -> Alice 4 Bob ->> Alice 5 Bob -\\ Alice 6 Bob \\\\- Alice 7 Bob //-- Alice 8 9 Bob ->o Alice 10 Bob o\\\\-- Alice 11 12 Bob <-> Alice 13 Bob <->o Alice 14 @enduml
(6)对消息序列编号:关键字 autonumber
用于自动对消息编号。语句 autonumber start
用于指定编号的初始值,而 autonumber startincrement
可以同时指定编号的初始值和每次增加的值。
1 @startuml 2 autonumber 3 Bob -> Alice : Authentication Request 4 Bob <- Alice : Authentication Response 5 @enduml
1 @startuml 2 autonumber 3 Bob -> Alice : Authentication Request 4 Bob <- Alice : Authentication Response 5 6 autonumber 15 7 Bob -> Alice : Another authentication Request 8 Bob <- Alice : Another authentication Response 9 10 autonumber 40 10 11 Bob -> Alice : Yet another authentication Request 12 Bob <- Alice : Yet another authentication Response 13 14 @enduml
1 @startuml 2 autonumber "<b>[000]" 3 Bob -> Alice : Authentication Request 4 Bob <- Alice : Authentication Response 5 6 autonumber 15 "<b>(<u>##</u>)" 7 Bob -> Alice : Another authentication Request 8 Bob <- Alice : Another authentication Response 9 10 autonumber 40 10 "<font color=red><b>Message 0 " 11 Bob -> Alice : Yet another authentication Request 12 Bob <- Alice : Yet another authentication Response 13 14 @enduml
1 @startuml 2 autonumber 10 10 "<b>[000]" 3 Bob -> Alice : Authentication Request 4 Bob <- Alice : Authentication Response 5 6 autonumber stop 7 Bob -> Alice : dummy 8 9 autonumber resume "<font color=red><b>Message 0 " 10 Bob -> Alice : Yet another authentication Request 11 Bob <- Alice : Yet another authentication Response 12 13 autonumber stop 14 Bob -> Alice : dummy 15 16 autonumber resume 1 "<font color=blue><b>Message 0 " 17 Bob -> Alice : Yet another authentication Request 18 Bob <- Alice : Yet another authentication Response 19 @enduml
(7)组合消息:我们可以通过以下关键词将组合消息:
alt/else
opt
loop
par
break
critical
group
, 后面紧跟着消息内容
可以在标头(header)添加需要显示的文字(group
除外)。关键词 end
用来结束分组。注意,分组可以嵌套使用。
1 @startuml 2 Alice -> Bob: Authentication Request 3 4 alt successful case 5 6 Bob -> Alice: Authentication Accepted 7 8 else some kind of failure 9 10 Bob -> Alice: Authentication Failure 11 group My own label 12 Alice -> Log : Log attack start 13 loop 1000 times 14 Alice -> Bob: DNS Attack 15 end 16 Alice -> Log : Log attack end 17 end 18 19 else Another type of failure 20 21 Bob -> Alice: Please repeat 22 23 end 24 @enduml
(8)给消息添加注释:我们可以通过在消息后面添加 note left
或者 note right
关键词来给消息添加注释。你也可以通过使用 end note
来添加多行注释。
1 @startuml 2 Alice->Bob : hello 3 note left: this is a first note 4 5 Bob->Alice : ok 6 note right: this is another note 7 8 Bob->Bob : I am thinking 9 note left 10 a note 11 can also be defined 12 on several lines 13 end note 14 @enduml
(9)Creole和html:
1 @startuml 2 participant Alice 3 participant "The **Famous** Bob" as Bob 4 5 Alice -> Bob : hello --there-- 6 ... Some ~~long delay~~ ... 7 Bob -> Alice : ok 8 note left 9 This is **bold** 10 This is //italics// 11 This is ""monospaced"" 12 This is --stroked-- 13 This is __underlined__ 14 This is ~~waved~~ 15 end note 16 17 Alice -> Bob : A //well formatted// message 18 note right of Alice 19 This is <back:cadetblue><size:18>displayed</size></back> 20 __left of__ Alice. 21 end note 22 note left of Bob 23 <u:red>This</u> is <color #118888>displayed</color> 24 **<color purple>left of</color> <s:red>Alice</strike> Bob**. 25 end note 26 note over Alice, Bob 27 <w:#FF33FF>This is hosted</w> by <img sourceforge.jpg> 28 end note 29 @enduml
(10)分隔符:你可以通过使用 ==
关键词来将你的图表分割多个步骤。
1 @startuml 2 3 == Initialization == 4 5 Alice -> Bob: Authentication Request 6 Bob --> Alice: Authentication Response 7 8 == Repetition == 9 10 Alice -> Bob: Another authentication Request 11 Alice <-- Bob: another authentication Response 12 13 @enduml
(11)生命线的激活与撤销:关键字activate
和deactivate
用来表示参与者的生命活动。一旦参与者被激活,它的生命线就会显示出来。activate
和deactivate
适用于以上情形。destroy
表示一个参与者的生命线的终结。
1 @startuml 2 participant User 3 4 User -> A: DoWork 5 activate A 6 7 A -> B: << createRequest >> 8 activate B 9 10 B -> C: DoWork 11 activate C 12 C --> B: WorkDone 13 destroy C 14 15 B --> A: RequestCreated 16 deactivate B 17 18 A -> User: Done 19 deactivate A 20 21 @enduml
1 @startuml 2 participant User 3 4 User -> A: DoWork 5 activate A #FFBBBB 6 7 A -> A: Internal call 8 activate A #DarkSalmon 9 10 A -> B: << createRequest >> 11 activate B 12 13 B --> A: RequestCreated 14 deactivate B 15 deactivate A 16 A -> User: Done 17 deactivate A 18 19 @enduml
(12)进入和发出消息:如果只想关注部分图示,你可以使用进入和发出箭头。使用方括号[
和]
表示图示的左、右两侧。
1 @startuml 2 [-> A: DoWork 3 4 activate A 5 6 A -> A: Internal call 7 activate A 8 9 A ->] : << createRequest >> 10 11 A<--] : RequestCreated 12 deactivate A 13 [<- A: Done 14 deactivate A 15 @enduml
1 @startuml 2 [-> Bob 3 [o-> Bob 4 [o->o Bob 5 [x-> Bob 6 7 [<- Bob 8 [x<- Bob 9 10 Bob ->] 11 Bob ->o] 12 Bob o->o] 13 Bob ->x] 14 15 Bob <-] 16 Bob x<-] 17 @enduml
(13)构造类型和圈点:可以使用<<
和>>
给参与者添加构造类型。在构造类型中,你可以使用(X,color)
格式的语法添加一个圆圈圈起来的字符。
1 @startuml 2 3 participant "Famous Bob" as Bob << Generated >> 4 participant Alice << (C,#ADD1B2) Testable >> 5 6 Bob->Alice: First message 7 8 @enduml
1 @startuml 2 3 skinparam guillemet false 4 participant "Famous Bob" as Bob << Generated >> 5 participant Alice << (C,#ADD1B2) Testable >> 6 7 Bob->Alice: First message 8 9 @enduml
(14)更多标题信息:在标题描述中使用\\n
表示换行。还可以使用关键字title
和end title
定义多行标题。
1 @startuml 2 3 title __Simple__ communication example\\non several lines 4 5 Alice -> Bob: Authentication Request 6 Bob -> Alice: Authentication Response 7 8 @enduml
1 @startuml 2 3 title 4 <u>Simple</u> communication example 5 on <i>several</i> lines and using <font color=red>html</font> 6 This is hosted by <img:sourceforge.jpg> 7 end title 8 9 Alice -> Bob: Authentication Request 10 Bob -> Alice: Authentication Response 11 12 @enduml
(15)包裹参与者:可以使用box
和end box
画一个盒子将参与者包裹起来。还可以在box
关键字之后添加标题或者背景颜色。
1 @startuml 2 3 box "Internal Service" #LightBlue 4 participant Bob 5 participant Alice 6 end box 7 participant Other 8 9 Bob -> Alice : hello 10 Alice -> Other : hello 11 12 @enduml
(16)移除脚注:使用hide footbox
关键字移除脚注。
1 @startuml 2 3 hide footbox 4 title Footer removed 5 6 Alice -> Bob: Authentication Request 7 Bob --> Alice: Authentication Response 8 9 @enduml
(17)外观参数(skinparam):
1 @startuml 2 skinparam sequenceArrowThickness 2 3 skinparam roundcorner 20 4 skinparam maxmessagesize 60 5 skinparam sequenceParticipant underline 6 7 actor User 8 participant "First Class" as A 9 participant "Second Class" as B 10 participant "Last Class" as C 11 12 User -> A: DoWork 13 activate A 14 15 A -> B: Create Request 16 activate B 17 18 B -> C: DoWork 19 activate C 20 C --> B: WorkDone 21 destroy C 22 23 B --> A: Request Created 24 deactivate B 25 26 A --> User: Done 27 deactivate A 28 29 @enduml

(18)填充区设置:可以设定填充区的参数配置。
1 @startuml 2 skinparam ParticipantPadding 20 3 skinparam BoxPadding 10 4 5 box "Foo1" 6 participant Alice1 7 participant Alice2 8 end box 9 box "Foo2" 10 participant Bob1 11 participant Bob2 12 end box 13 Alice1 -> Bob1 : hello 14 Alice1 -> Out : out 15 @enduml
第二部分:《工厂采购》系统对象交互顺序
- 采购员选择订货货品。
- 到达订货界面,开始接收客户信息,接收货品信息,显示货品信息。
- 到达订货管理器,创建客户,取货品信息,创建订单。
- 创建客户到达客户区。
- 取货品信息到达货品区。
- 创建订单到订单区。
