如何創(chuàng)建參數(shù)捕獲器Map<String, SomeCustomClass>？我的代碼遵循以下模式：import java.util.HashMap;import java.util.Map;public class CompoundClass {   public CompoundClass (String a, String b){       this.a = a;       this.b = b;   }   public String a;   public String b;}public class SubClass {    public void doSomeThingSubClass(Map<String, CompoundClass> mapSb) {        ...    }}public class Example {    public SubClass sb;    public Example(SubClass sb) {        this.sb = sb;    }    public void doSomeThing () {        Map<String, CompoundClass> mapSb = new HashMap<>();        mapSb.put("x", new CompoundClass("aa","bb"));        sb.doSomeThingSubClass(mapSb);    }}而且我想測(cè)試是否調(diào)用了該方法doSomethingSubClass(mapSb)，因此我需要能夠檢查它被調(diào)用的參數(shù)。為此，我進(jìn)行了以下單元測(cè)試：@Testvoid TestDoSomehing(){    SubClass sb = mock(SubClass.class);        Example ex = new Example(sb);        ArgumentCaptor<Map<String, CompoundClass>> argCaptor = ArgumentCaptor.forClass(Map<String, CompoundClass>.class);    ex.doSomeThing();    verify(sb).doSomeThingSubClass(argCaptor.capture());        System.out(argCaptor.getValue().get('x').a);}問(wèn)題是 argCaptor 的上述初始化會(huì)產(chǎn)生以下錯(cuò)誤消息：“無(wú)法從參數(shù)化類(lèi)型中選擇”。因此，問(wèn)題是如何以正確的方式聲明一個(gè)映射對(duì)象的參數(shù)捕獲器的初始化，例如Map<String, SomeCustomeClass>？提前致謝！
