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 <-<--,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

技术图片

(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<>替换成\\或者 /
  • 细箭头:将箭头标记写两次 (如 >>//)
  • 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

技术图片技术图片

 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

(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

(11)生命线的激活与撤销:关键字activatedeactivate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。activatedeactivate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

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

(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[]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

15 Bob <-]
16 Bob x<-]

(13)构造类型和圈点:可以使用<<>>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。

3 participant "Famous Bob" as Bob << Generated >>
4 participant Alice << (C,#ADD1B2) Testable >>

(15)包裹参与者:可以使用boxend 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

 3 box "Internal Service" #LightBlue
 4     participant Bob
 5     participant Alice
 6 end box
