每当无法加载注释类型时，就会引发此异常。正如消息所述(Thomas 在他的回复中解释)，可能发生这种情况的一种情况是当您在开发模式 session 期间添加新的注释类型时。

出现此错误的另一种可能方法是 GWT 编译器的类路径上没有 org.hibernate.validator.constraints.ConstraintComposition。尝试使用 mvn -X gwt:compile 进行编译，并查看 GWT 编译器使用的类路径。验证您的 GWT 编译类路径是否包含一个包含 org/hibernate/validator/constraints/ConstraintComposition.class 的 .jar。
