無法獲得可用的提供程序解析程序

Question

當我們使用Bean驗證時，它工作正常。但運行一段時間後，有一個RuntimeException：

javax.validation.ValidationException: Unable to get available provider resolvers.

LIB：冬眠 - 驗證 - 5.0.1.Final.jar

我從WebSphere得到這個錯誤。 validation-api-1.0.0.GA.jar一直被添加到目標EAR文件中。直到我將類加載策略更改爲「最後一個父母」之前，這絕不是問題。我也得到此異常：

java.lang.ClassCastException：與javax.validation.spi.ValidationProvider

org.apache.bval.jsr303.ApacheValidationProvider不兼容的解決方案是去除驗證的API -1.0.0.GA.jar通過添加以下依賴項，它將validation-api設置爲「provided」：

<dependency> 
     <groupId>javax.validation</groupId> 
     <artifactId>validation-api</artifactId> 
     <version>1.0.0.GA</version> 
     <scope>provided</scope> 
    </dependency>
