WSO2 API Surf OAuth 作为第三方 KeyManager 的管理器配置问题
WSO2 API Manager Config issue with Surf OAuth as Third Party KeyManager
我正在尝试将 Surf OAuth 用作 WSO2 API 管理器的第三方密钥管理器。按照 https://docs.wso2.com/display/AM1100/Configuring+a+Third-Party+Key+Manager
中的文档
我的问题是，当我在 api-manager.xml 中添加 Surf OAuth 配置时，WSO2 API 管理器在尝试读取配置时因 NPE 而崩溃。它看起来像是在某些系统 属性 上爆炸，例如 CARBON_HOME 并抛出 NPE。
其他人是否遇到过与 WSO2 API Manager 和 Surf OAuth 集成类似的问题？我很好奇为什么它在一步一步地指导之后仍然无法正常工作
这是我的 api-manager.xml 配置
<APIKeyManager>
<KeyManagerClientImpl>nl.surfnet.demo.SurfOAuthClient</KeyManagerClientImpl>
<Configuration>
<RegistrationEndpoint>http://myserver:8080/admin/resourceServer/101</RegistrationEndpoint>
<AccessToken>4a3aa6a5-8f37-4267-8911-0e3049ccee86</AccessToken>

</Configuration>
</APIKeyManager>

APIM 最新版本 (1.10.0) 不支持文档中提供的 Surf-oauth 客户端实现。因此，您需要进行以下更改才能解决此问题。
更改 SurfOAuthClient.java 文件以导入 org.wso2.carbon.apimgt.impl.AbstractKeyManager class 而不是 org.wso2.carbon.apimgt.keymgt.AbstractKeyManager class.
导入组织.wso2.carbon.apimgt.impl.AbstractKeyManager;
在pom.xml文件中将"org.wso2.carbon.apimgt"组ids的版本改为5.0.3如下。

另请参考[1]获取固定代码。构建代码，生成 war 文件和 jar 文件。
从 /repository/components/lib 和 /repository/components/dropins 文件夹中删除当前 gateway.client-1.0.0.jar 文件，并将生成的 jar 文件复制到 /repository/components/lib 文件夹。
使用生成的 war 文件并再次进行配置。
