IntelliJ IDEA 2020.3.1 x64同问题

[liuzhihang]

是插件都不能用还是只是某个接口不能用。 我暂时还没有遇到

[AlkTTT]

@liuzhihang 插件不能用

[liuzhihang]

最低版本是 2021.3 你确认下版本，我现在是正常的呀。

[AlkTTT]

我的是IntelliJ IDEA 2020.3.1 x64，doc-view版本1.2.3

[liuzhihang]

升级一下 doc-view 版本呢？ 可能是版本问题。我也排查一下

我的是IntelliJ IDEA 2020.3.1 x64，doc-view版本1.2.3

[AlkTTT]

2020.3.1的插件里，只支持到1.2.3，可能是你没加版本兼容
我现在把idea升级到2022.2，doc-view升级到1.3.1
还是会报同样的错误，是不是和其他插件冲突了？（已排除官方中文插件）

[liuzhihang]

@AlkTTT
这个接口是有泛型的接口吧？

[AlkTTT]

是的，我把泛型去掉后就可以了，多谢

[liuzhihang]

是的，我把泛型去掉后就可以了，多谢

那我定位到问题了，我看着这块代码确实存在问题。

[liuzhihang]

是的，我把泛型去掉后就可以了，多谢

@AlkTTT 方便告诉我下你的接口出错的这个泛型怎么写的么？ 我试着支持一下

[AlkTTT]

public R<?> test(Query query)
R是自己封装的通用返回类

[liuzhihang]

public R<?> test(Query query) R是自己封装的通用返回类

这个接口的返回值是直接用的 ？没有具体指定那种类型是吧。如果指定了泛型的类型这种应该是可以的。我后面加一个 ? 的处理
