我正在尝试使用Surf OAuth作为WSO2 API Manager的第三方密钥管理器。遵循https://docs.wso2.com/display/AM1100/Configuring+a+Third-Party+Key+Manager
的文档我的问题是，当我在api-manager.xml中添加Surf OAuth的配置时，WSO2 API Manager会在尝试读取配置时爆炸NPE。看起来它正在炸毁一些系统属性，如CARBON_HOME和抛出NPE。
是否还有其他人遇到与WSO2 API Manager和Surf OAuth集成类似的问题？我很感兴趣，为什么即使按照一步一步的指示它也不起作用
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>
<IntrospectionURL>http://myserver:8080/v1/tokeninfo</IntrospectionURL>

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问题。
更改SurfOAuthClient.java文件以导入org.wso2.carbon.apimgt.impl.AbstractKeyManager类，而不是org.wso2.carbon.apimgt.keymgt.AbstractKeyManager类。
import org.wso2.carbon.apimgt.impl.AbstractKeyManager;
更改＆＃34; org.wso2.carbon.apimgt＆＃34;的版本pom.xml文件中的组ID为5.0.3，如下所示。
<dependency>
<groupId>org.wso2.carbon.apimgt</groupId>
<artifactId>org.wso2.carbon.apimgt.impl</artifactId>
<version>5.0.3</version>
</dependency>
<dependency>
<groupId>org.wso2.carbon.apimgt</groupId>
<artifactId>org.wso2.carbon.apimgt.gateway</artifactId>
<version>5.0.3</version>
</dependency>
<dependency>
<groupId>org.wso2.carbon.apimgt</groupId>
<artifactId>org.wso2.carbon.apimgt.keymgt</artifactId>
<version>5.0.3</version>
</dependency>
<dependency>
<groupId>org.wso2.carbon.apimgt</groupId>
<artifactId>org.wso2.carbon.apimgt.hostobjects</artifactId>
<version>5.0.3</version>
</dependency>
另请参阅[1]了解固定代码。构建代码，生成war文件和jar文件。 从/ repository / components / lib和/ repository / components / dropins文件夹中删除当前的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。
