ResolvableType.resolve介绍

[英]Resolve this type to a java.lang.Class, returning nullif the type cannot be resolved. This method will consider bounds of TypeVariable and WildcardType if direct resolution fails; however, bounds of Object.class will be ignored.

If this method returns a non-null Class and #hasGenerics()returns false, the given type effectively wraps a plain Class, allowing for plain Class processing if desirable.
[中]将此类型解析为java。类，如果无法解析类型，则返回null。如果直接分解失败，该方法将考虑类型和WildcardType的界限；然而，对象的边界是有限的。课堂将被忽略。
如果此方法返回一个非null类，而#hasGenerics（）返回false，那么给定的类型将有效地包装一个普通类，如果需要，允许进行普通类处理。
