The sequence -> is used to draw a message between two
participants.
Participants do not have to be explicitly declared.
To have a dotted arrow, you use -->
It is also possible to use <- and <--.
That does not change the drawing, but may improve readability.
Note that this is only true for sequence diagrams, rules are different for the other diagrams.
@startuml
Alice -> Bob: Authentication Request
Bob --> Alice: Authentication Response
Alice -> Bob: Another authentication Request
Alice <-- Bob: Another authentication Response

You can change arrow style by several ways:
add a final x to denote a lost message
use \ or / instead of < or > to have only the bottom or top part of the arrow
repeat the arrow head (for example, >> or //) head to have a thin drawing
use -- instead of - to have a dotted arrow
add a final "o" at arrow head
use bidirectional arrow <->
@startuml

对消息序列编号
关键字 autonumber 用于自动对消息编号。
@startuml
autonumber
Bob -> Alice : Authentication Request
Bob <- Alice : Authentication Response
@enduml
@startuml
autonumber
Bob -> Alice : Authentication Request
Bob <- Alice : Authentication Response
autonumber 15
Bob -> Alice : Another authentication Request
Bob <- Alice : Another authentication Response
autonumber 40 10
Bob -> Alice : Yet another authentication Request
Bob <- Alice : Yet another authentication Response
@enduml
你可以在双引号内指定编号的格式。
格式是由 Java 的DecimalFormat类实现的:
(0 表示数字;# 也表示数字,但默认为0)。
你也可以用 HTML 标签来制定格式。
@startuml
autonumber "<b>[000]"
Bob -> Alice : Authentication Request
Bob <- Alice : Authentication Response
autonumber 15 "<b>(<u>##</u>)"
Bob -> Alice : Another authentication Request
Bob <- Alice : Another authentication Response
autonumber 40 10 "<font color=red><b>Message 0 "
Bob -> Alice : Yet another authentication Request
Bob <- Alice : Yet another authentication Response
@enduml
@startuml
autonumber 10 10 "<b>[000]"
Bob -> Alice : Authentication Request
Bob <- Alice : Authentication Response
autonumber stop
Bob -> Alice : dummy
autonumber resume "<font color=red><b>Message 0 "
Bob -> Alice : Yet another authentication Request
Bob <- Alice : Yet another authentication Response
autonumber stop
Bob -> Alice : dummy
autonumber resume 1 "<font color=blue><b>Message 0 "
Bob -> Alice : Yet another authentication Request
Bob <- Alice : Yet another authentication Response
@enduml
Message sequence numbering
The keyword autonumber is used to
automatically add number to messages.
@startuml
autonumber
Bob -> Alice : Authentication Request
Bob <- Alice : Authentication Response
@enduml
You can specify a startnumber with autonumber //start// , and
also an increment with autonumber //start// //increment//.
@startuml
autonumber
Bob -> Alice : Authentication Request
Bob <- Alice : Authentication Response
autonumber 15
Bob -> Alice : Another authentication Request
Bob <- Alice : Another authentication Response
autonumber 40 10
Bob -> Alice : Yet another authentication Request
Bob <- Alice : Yet another authentication Response
@enduml
You can specify a format for your number by using between double-quote.
The formatting is done with the Java class DecimalFormat
(0 means digit, # means digit and zero if absent).
You can use some html tag in the format.
@startuml
autonumber "<b>[000]"
Bob -> Alice : Authentication Request
Bob <- Alice : Authentication Response
autonumber 15 "<b>(<u>##</u>)"
Bob -> Alice : Another authentication Request
Bob <- Alice : Another authentication Response
autonumber 40 10 "<font color=red><b>Message 0 "
Bob -> Alice : Yet another authentication Request
Bob <- Alice : Yet another authentication Response
@enduml
You can also use autonumber stop and
autonumber resume //increment// //format// to respectively pause and resume
automatic numbering.
@startuml
autonumber 10 10 "<b>[000]"
Bob -> Alice : Authentication Request
Bob <- Alice : Authentication Response
autonumber stop
Bob -> Alice : dummy
autonumber resume "<font color=red><b>Message 0 "
Bob -> Alice : Yet another authentication Request
Bob <- Alice : Yet another authentication Response
autonumber stop
Bob -> Alice : dummy
autonumber resume 1 "<font color=blue><b>Message 0 "
