【问题描述】：
我需要为 wso2 api 管理编写自定义令牌验证器类。我尝试扩展 DefaultOAuth2TokenValidator 类，将其转换为 jar 并放置在 /repository/components/extensions 中。代码sn-p在下面提到。
import org.wso2.carbon.identity.oauth2.IdentityOAuth2Exception;
import org.wso2.carbon.identity.oauth2.validators.DefaultOAuth2TokenValidator;
import org.wso2.carbon.identity.oauth2.validators.OAuth2TokenValidationMessageContext;
public class CustomTokenValidator extends DefaultOAuth2TokenValidator{
public boolean validateAccessToken(OAuth2TokenValidationMessageContext arg0)
throws IdentityOAuth2Exception
{
System.out.println("CUSTOM VALIDATION INVOKED");
return true;
}
}
我在 /repository/conf/identity.xml 的标签下添加了以下内容作为最后一个子条目
<TokenValidators>
<TokenValidator type="bearer" class="com.example.custom.token.generator.CustomTokenValidator"/>
</TokenValidators>
我将所有丢失的 jars（重新启动服务器时找不到类异常）放在同一位置，直到它抛出下面提到的错误。我很茫然。请多多指教。
