当我们使用Bean验证时，它运行正常。但运行一段时间后，就会出现RuntimeException：

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

我从WebSphere得到了这个错误。 validation-api-1.0.0.GA.jar一直被添加到目标EAR文件中。在我将类加载策略更改为“parent last”之前，这从来都不是问题。我也得到了这个例外：

java.lang.ClassCastException：org.apache.bval.jsr303.ApacheValidationProvider与javax.validation.spi.ValidationProvider不兼容

解决方案是通过添加以下依赖项从目标EAR文件中删除validation-api-1.0.0.GA.jar，该依赖项将validation-api设置为“provided”：

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

无法获得可用的提供商解析程序
