Spring Boot 2.0.2.RELEASE 的模型验证异常
Model validation exception with Spring Boot 2.0.2.RELEASE
我在迁移到 Spring Boot 2.0.2.RELEASE 时遇到一些问题。
似乎 hibernate 验证器试图验证 Enum Kotlin 类型的默认文件。

Spring Boot 1.5.10 不会发生此异常。
有没有人遇到过同样的问题？我在互联网上和这里都没有找到任何答案。有人可以帮帮我吗？
所以问题如下：
- 反射API提供的构造函数是：
com.test.simple.Group(java.lang.String $enum$name, int $enum$ordinal, java.lang.String groupName, java.lang.String groupDescription)所以它有四个参数。我想名称和序号已传递给构造函数；
KotlinReflectionParameterNameDiscoverer提供的参数名称只有[groupName, groupDescription]（所以不考虑附加参数）。
KotlinReflectionParameterNameDiscoverer应该尽量与Java反射APIreturns保持一致。否则它绝对不能用作 HV ParameterNameProvider.
