加了ApiDoc注解就報錯 不加啥問題沒有 #7

Closed Yanghongkang closed 3 years ago

Yanghongkang commented 3 years ago

加了ApiDoc注解 就報返回的對象强轉報錯 返回對象就一個汎型啊

java.lang.ClassCastException: java.lang.Class cannot be cast to java.lang.reflect.ParameterizedType

返回对象有泛型,但是实际使用的时候没有添加泛型, 是这样吗? 例如返回对象的定义类似 

public class ResponseResult<T> ...

而使用的地方没有传泛型,而直接使用了 ResponseResult 这样的情况下出现的异常?

我在使用的时候也遇到该问题，debug发现是因为使用了BigDecimal，就会出现该异常，在ClassTypeUtil里增加BigDecimal的处理就可以了~

@Yanghongkang 您好,我这边暂时无法复现您的问题, 我们将要发布 2.7.8.2 版本,请您到时候再用这个版本试试? 或者可以用 2.7.x 分支的最新代码试试?

fteng1024 commented 3 years ago

@KeRan213539 你好，我这边也出现了这样的问题，我在实现类里面指定了具体的对象，但是反射的时候好像并没有拿到我这边指定的具体类型

近期做了一波修复，等2.7.8.2发版了再试试？年后应该可以发版
