SpringBoot+webservice

今天看到一個項目要和工廠的ERP進行對接，用到了webservice。雖然使用用springboot較爲方便，仍是瞭解一下：

webservice是什麼

網上的解釋不少，其實就是跨語言和操做系統的的遠程調用技術。好比亞馬遜，能夠將本身的服務以webservice的服務形式暴露出來，咱們就能夠經過web調用這些，不管咱們使用的語言是java仍是c，這也是SOA應用一種表現形式。

WSDL(Web Services Description Language)將不管用何種語言書寫的web service描述出來，好比其參數或返回值。WSDL是服務端和客戶端都能解讀的標準格式。客戶端經過URL地址訪問到WSDL文件，在調用服務端以前先訪問WSDL文件。 讀取到WSDL後經過客戶端的API類能夠生成代理類，調用這些代理類就能夠訪問webservice服務。代理類將客戶端的方法變爲soap（Simple Object Access Protocol，能夠理解爲http+xml）格式經過http發送，同時接受soap格式的返回值並解析。
