Capture of是一个术语,它可以指代多个不同的概念。以下是一些常见的含义:
1. Capture of是指战争或冲突中的占领或控制。在军事上,当一个军队成功地攻占了敌方领土或据点,我们可以说这是一次Capture of。
2. Capture of也可以指电子设备或软件中的截屏功能。当我们使用手机、电脑或其他设备时,我们可以用"capture"来描述我们正在截取屏幕上的信息。

Cannot resolve method 'exportBigExcel(ExportParams, Class<capture of ?>, List<capture of ?>, int)'
This error message typically occurs when the method being called does not match the expected method signature.
In this case, the method "exportBigExcel()" is being called with four parameters:
1. an ExportParams object
2. a Class object
3. a List object
4. an integer
The error message suggests that the types of the second and third parameters are not being recognized as expected.
The terms "capture of ?" indicate that the types of these parameters are being inferred by the compiler based on the context in which the method is being called.
To fix this error, you may need to explicitly specify the types of the second and third parameters, or ensure that they are compatible with the expected types.
For example:
- If the second parameter is expected to be a specific class, you can replace "capture of ?" with the appropriate class name.
- If the third parameter is expected to be a list of a specific type, you can replace "capture of ?" with the appropriate type name.
Alternatively, you may need to check that the method being called is the correct method, and that it is defined with the expected parameters.
Required type: Collector <? super Person, A, R> Provided: Collector <CharSequence, capture of ?, String> reason: no instance(s) of type variable(s) exist so that Person conforms to CharSequence
这个错误提示的意思是在使用Collector时,期望的类型是Collector<? super Person, A, R>,但是实际提供的类型是Collector<CharSequence, capture of ?, String>。这是因为类型变量不匹配导致的,无法将Person类型转换为CharSequence类型。
要解决这个问题,需要检查Collector的定义,确保它的类型参数与要使用的类的类型参数相匹配。如果Collector定义中的类型参数无法满足要求,可以考虑使用通配符或泛型边界来限制类型参数的范围,以确保类型匹配。同时,也需要确保传递给Collector的元素类型与Collector类型参数中指定的类型相匹配。
