如何使用visio画UML序列图

?今天尝试使用visio画了一个序列图。

话不多说，先打开visio，新建一个UML序列。

先新建几个对象生命线

加入几个激活

而后是消息，实线表示请求，虚线表示响应。

当然如果不影响理解，可以不用每个请求都配上一个响应。

此UML例子是在《UML精粹：标准对象建模语言简明指南》中拿过来的，为了更好的理解这个UML，下面使用java来实现此UML。

*/

publicclassOrderTest{

@org.junit.Test

publicvoidcalculatePrice(){

//这个商品是鞋子,123块钱一双

ProductproductShoes=newProduct();

productShoes.setName("shoes");

productShoes.setPrice(123);

//这个商品是袜子,8块钱一双

ProductproductSocket=newProduct();

productSocket.setName("socket");

productSocket.setPrice(8);

//这是一个老客户，打七折

Customercustomer=newCustomer();

customer.setDiscount(0.7);

//这个客户下了一个单

Orderorder=newOrder();

order.setCustomer(customer);

//买了一双鞋子，两双袜子

OrderLineorderLineShoes=newOrderLine(1,productShoes);

OrderLineorderLineSocket=newOrderLine(2,productSocket);

ListorderLineList=newArrayList();

orderLineList.add(orderLineShoes);

orderLineList.add(orderLineSocket);

order.setOrderLineList(orderLineList);

//算一算总共多少钱

doublepriceActual=order.calculatePrice();

Assert.assertEquals("97.3",String.valueOf(priceActual));

}

}

测试用例的输出

productname:shoesprice:123.0number:1orderlineprice:123.0

productname:socketprice:8.0number:2orderlineprice:16.0

orderbaseprice:139.0

orderdiscountedprice:97.3
