Question

在Mule EE 3.8.5中，我在加载oauth2访问令牌时遇到ClassCastException。我正在使用mule-module-security-oauth2-provider 1.7.2版和mule-module-objectstore 2.1.0

stracktrace开始了：

java.lang.ClassCastException: java.lang.String cannot be cast to org.mule.modules.oauth2.provider.token.AccessTokenStoreHolder
at org.mule.modules.oauth2.provider.token.ObjectStoreTokenStore.retrieveByAccessToken(ObjectStoreTokenStore.java:38)
at org.mule.modules.oauth2.provider.token.TokenManager.getNonExpiredAccessTokenHolder(TokenManager.java:116)
at org.mule.modules.oauth2.provider.OAuth2ProviderModule.validate(OAuth2ProviderModule.java:543)
at org.mule.modules.oauth2.provider.processors.ValidateMessageProcessor$1.process(ValidateMessageProcessor.java:178)

at org.mule.modules.oauth2.provider.processors.ValidateMessageProcessor.doProcess(ValidateMessageProcessor.java:164)

我的配置将令牌成功存储到以下形式的简单H2数据库表中：

创建表ACCESSTOKENOBJECTSTORE（k varchar（1000），v varchar（1000000））

我可以看到在此表中创建了令牌，但在尝试验证令牌时我得到了ClassCastException。我的流程看起来像：

更新

blob类型更适合v列。但是对于导致以下结果的DB2驱动程序：

Answer 1

您的配置似乎对我来说很好。
我改变它的唯一工作就是改变创建DB表的方式和它的数据类型以下脚本将帮助您在h2 db中创建具有准确数据类型的表：

CREATE TABLE IF NOT EXISTS ACCESSTOKENOBJECTSTORE (
  id NUMBER AUTO_INCREMENT,
  k VARCHAR(256),
  v OTHER,
  constraint ACCESSTOKENOBJECTSTORE_pk PRIMARY KEY(id)
);

从JdbcObjectStore加载oauth2访问令牌时出现ClassCastException
