Question

我有一个传统的Spring应用程序需要维护。该应用程序使用spring框架和spring beanutils。我升级到4.x. 但是，当我在jetty上运行时，我发现了这个错误

我发现函数ClassUtils.forName（String）在SpringFraemwork 3中已弃用，而在4中则不再使用。

我可以找到springmodules validation jar 0.9.0的新替代品吗？

新的不应该调用此函数，应该调用ClassUtils.forName（String，ClassLoader）。

它是否包含在新的春季罐中？

我发现了一些名为Hibernate-validator的东西，我不确定这可能会有所帮助。

已经一年了，但是我正在回答，考虑是否有人仍然需要解决方案。最近，我在应用程序中使用 Bean Validation 1.0（JSR-303）和 Bean Validation 1.1（JSR-349）替代了spring-modules-validation作为替代解决方案。我的应用程序使用的是Spring Framework4。我已将 spring-modules-validation 的依赖项替换为 javax.validation：validation-api 和 org.hibernate.validator ：hibernate-validator 。

关于实现，这取决于您要替换的bean验证程序，例如@Length的{{1}}可以被org.springmodules.validation.bean.conf.loader.annotation.handler.Length的{{1}}替换。类似{{1} @Size的}可以替换为javax.validation.constraints.Size的{{1}}等。您可以使用类@NotBlank而不是org.springmodules.validation.bean.conf.loader.annotation.handler.NotBlank创建验证器bean。

请注意，这些只是JSR 303中可用的一些注释。此外，Hibernate Validator引入了一些自己的注释。请找到春季文档here

是否有com.springsource.org.springmodules.validation.validator 0.9.0的更新替代品？
