java - 当我尝试从 wsdl 生成客户端时出错

Question

我想从 wsdl 生成一个 java 客户端。

所以我创建了一个新项目，将 wsdl 导入到项目中，然后右键单击 -> Web 服务 -> 生成客户端。

所以这是我使用的选项:

然后点击鱼，我有这个错误:

Answer 1

您的 WSDL 导入一个带有 URL 的模式，该 URL 具有 https 地址方案。此错误表明您的 Java 安装不“信任”托管正在导入的此模式的服务器提供的证书。

你有几个选择:

1. 将服务器的 CA 证书或服务器的实际证书导入您的信任库
2. 将架构下载到本地位置并更改 WSDL 中的导入 url

我会推荐第二个选项，因为只要将 WSDL 和上述模式打包在一起，它的可移植性会稍微好一些。
