149.10. HL7 Validation predicate

通常最好首先解析 HL7v2 消息，并在单独的步骤中根据 HAPI ValidationContext 验证它。

示例：

import static org.apache.camel.component.hl7.HL7.messageConformsTo;
import ca.uhn.hl7v2.validation.impl.DefaultValidation;

   // Use standard or define your own validation rules
   ValidationContext defaultContext = new DefaultValidation();

   // Throws PredicateValidationException if message does not validate
   from("direct:test1")
      .validate(messageConformsTo(defaultContext))
      .to("mock:test1");
