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并放在/ repository / components / extensions中。代码段如下所述。
<TokenValidators>
<TokenValidator type="bearer" class="com.example.custom.token.generator.CustomTokenValidator"/>
</TokenValidators>
我将以下内容添加为/repository/conf/identity.xml

我把所有丢失的jar（在重新启动sevrer时找不到类的异常）放在同一个位置，直到它抛出下面提到的错误。我很茫然。请建议。
ssh USER@example.net -p 733
答案 0 :(得分：0)
您必须将JAR文件放入<WSO2_AM>/repository/components/lib目录。
