嘗試從 wsdl 生成客戶端時出錯

Question

我想從 wsdl 生成一個 java 客戶端。

所以我創建了一個新項目，將 wsdl 導入到項目中，然后右鍵單擊 -> web services -> Generate Client。

所以這是我使用的選項：

然后點擊魚，我有這個錯誤：

Answer 1

您的 WSDL 使用帶有https地址方案的 URL 導入模式。 此錯誤表明您的 Java 安裝不“信任”托管正在導入的此架構的服務器提供的證書。

你有幾個選擇：

1. 將服務器的 CA 證書或服務器的實際證書導入您的信任庫
2. 將模式下載到本地位置並更改 WSDL 中的導入 url

我會推薦第二個選項，因為只要您將 WSDL 和上述模式打包在一起，它的可移植性會稍微好一些。

Answer 2

我建議您嘗試使用以下 wsdl 文件http://www.webservicex.com/globalweather.asmx?WSDL的示例

生成客戶端。

並確保您啟動了服務器。 如果這工作正常。 那么，你的問題就迎刃而解了。
