5 years ago 经测试,是测试用例的问题.如果存在继承的必须明确指出使用哪个类型.否则将以指定的类型进行反序列化 以下是修改后的代码,可以通过
public static class ElementContent {
private String id;
private String name;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
public static class VarElement extends ElementContent {
private ElementContent defineName;
private List<List<CaseWhenElement>> children;
public ElementContent getDefineName() {
return defineName;
}
public void setDefineName(ElementContent defineName) {
this.defineName = defineName;
}
public List<List<CaseWhenElement>> getChildren() {
return children;
}
public void setChildren(List<List<CaseWhenElement>> children) {
this.children = children;
}
}
public static class CaseWhenElement extends VarElement {
private List<CaseWhen> caseWhens;
private List<ElementContent> theElse;
public List<CaseWhen> getCaseWhens() {
return caseWhens;
}
public void setCaseWhens(List<CaseWhen> caseWhens) {
this.caseWhens = caseWhens;

}
public static class CaseWhen {
private List<ElementContent> theCase = new ArrayList<ElementContent>();
private List<ElementContent> theWhen = new ArrayList<ElementContent>();
public List<ElementContent> getTheCase() {
return theCase;
}
public void setTheCase(List<ElementContent> theCase) {
this.theCase = theCase;
}
public List<ElementContent> getTheWhen() {

String json = JSON.toJSONString(varElement);
VarElement element = JSON.parseObject(json, VarElement.class);
Assert.assertEquals(json, JSON.toJSONString(element));
}
泛型类反序列化失败 `import java.util.ArrayList; import java.util.List;
