我有一個簡單的 Spring Boot 項目，其中調(diào)度程序定期使用 RESTful API 并轉(zhuǎn)換傳入的 JSON 文件。JSON 文件實際上是具有一些鍵和值的對象數(shù)組：[{"CoID":1,"CoName":"??????? ? ???????? ?????","CoNameEnglish":"MagsalAgriculture & Animal Husbandry Co.","CompanySymbol":"MAGS","CoTSESymbol":"?????","GroupID":1,"GroupName":"??????? ? ????????","IndustryID":1,"IndustryName":"???????? ???????? ? ????? ?????? ?? ??","InstCode":"5054819322815158","TseCIsinCode":"IRO1MAGS0006","TseSIsinCode":"IRO1MAGS0001","MarketID":1,"MarketName":"????"},...]我有一個名為的類，其Company字段與 JSON 文件中數(shù)組中的對象之一類似：@JsonIgnoreProperties(ignoreUnknown = true)public class Company {private int CoID;private String CoName;private String CoNameEnglish;private String CompanySymbl;private String CoTSESymbl;private int GroupID;private String GroupName;private int IndustryID;private String IndustryName;private String IndustryCode;private String TseCIsinCode;private String TseSIsinCode;private int MarketID;private String MarketName; // And proper getters, setters and constructor //我還創(chuàng)建了一個名為的包裝類CompanyList：public class CompanyList {private ArrayList<Company> companyList;public ArrayList<Company> getCompanyList() { return companyList;}public void setCompanyList(ArrayList<Company> companyList) { this.companyList = companyList;}public CompanyList() {}@Overridepublic String toString() { return "CompanyList [companyList=" + companyList + "]";}}

第二種和第三種方法應(yīng)該可以正常工作。您需要檢查您的 json 響應(yīng)結(jié)構(gòu)。
您可以使用以下 json 進行測試（它們適用于您的代碼）：
第二種方法：
[{"tseCIsinCode":null,"tseSIsinCode":null,"coName":"n1","industryID":0,"coID":0,"coNameEnglish":null,"companySymbl":null,"coTSESymbl":null,"groupID":0,"groupName":null,"industryName":null,"industryCode":null,"marketID":0,"marketName":null},{"tseCIsinCode":null,"tseSIsinCode":null,"coName":"n2","industryID":0,"coID":0,"coNameEnglish":null,"companySymbl":null,"coTSESymbl":null,"groupID":0,"groupName":null,"industryName":null,"industryCode":null,"marketID":0,"marketName":null}]第三：
{"companyList":[{"coName":"n1","coID":0,"coNameEnglish":null,"companySymbl":null,"coTSESymbl":null,"groupID":0,"groupName":null,"industryID":0,"industryName":null,"industryCode":null,"tseCIsinCode":null,"tseSIsinCode":null,"marketID":0,"marketName":null},{"coName":"n2","coID":0,"coNameEnglish":null,"companySymbl":null,"coTSESymbl":null,"groupID":0,"groupName":null,"industryID":0,"industryName":null,"industryCode":null,"tseCIsinCode":null,"tseSIsinCode":null,"marketID":0,"marketName":null}]}更新：
第二種方法修復(fù)：更改 json 字段名稱 -“CoName”->“coName”、“CoID”->“coID”等。更改后它將完美運行。
第三種方法修復(fù)：用第二種方法包裝你的 json"{\"companyList\":[...] 并更改字段名稱
第二次更新 如果您無法更改響應(yīng)中的 json。您可以在 Company 類中使用映射
@JsonProperty("CoName")
private String CoName;添加回答
