这是我尝试反序列化的对象:
public class DomaineBO {
private String nom;
private Set<String> codesQC;
private Set<String> codesSql;
...
这是我的 JSon 数据:

这是我尝试转换它们的方法:
GsonBuilder builder = new GsonBuilder();
Gson gson = builder.create();
DomaineBO[] infos = (DomaineBO[]) gson.fromJson(getJSonResponse(url), clazz);
Arrays.asList(infos);
当我在类 DomaineBO 中执行转换操作时，我收到 JsonSyntaxException 并显示消息 Expected a string but was BEGIN_OBJECT at line 1 column 51 path $[0] .codesQC[0]
我认为这是因为字符串集的属性。 我可以尝试用数组来实现，但我想知道是否有更好的方法？
最佳答案
这是因为在代码中你有一组字符串。使用字段 id、nom、nomHTML 创建 CodeQC 类并进行更改
Set<String> codesQC
至
Set<CodeQC> codesQC
关于java - Google Gson - com.google.gson.JsonSyntaxException : java. lang.IllegalStateException:需要一个字符串，但实际上是 BEGIN_OBJECT，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/33152108/
