gson.JsonSyntaxException：java.lang.IllegalStateException：

Question

我是gson的新手，但遇到此错误。

com.google.gson.JsonSyntaxException：java.lang.IllegalStateException：预期为BEGIN_OBJECT，但在第1行2527列的BEGIN_ARRAY路径$ .data.batting [0] .scores [1] .dismissal-by

这是因为API提供的json回复不同。

这是json回复：

 "batting": [
  {
    "scores": [
      {
        "dismissal-by": {
          "name": "CE Rudd",

            "name": "M du Preez",

        "batsman": "Extras",
        "pid": 0
      }
    ],
    "title": "Lancashire Thunder Innings"
  },

在第二个解雇对象处得到错误。

第一个解雇对象从一个对象开始，第二个解雇对象由一个数组开始。

这是scores数组的Java类

public class Score__ implements Serializable {

@SerializedName("dismissal-by")
@Expose
private DismissalBy dismissalBy;
@SerializedName("dismissal")
@Expose
private String dismissal;
@SerializedName("SR")
@Expose
private String sR;
@SerializedName("6s")
@Expose
private String _6s;
@SerializedName("4s")
@Expose
private String _4s;
@SerializedName("B")
@Expose
private String b;
@SerializedName("R")
@Expose
private String r;
@SerializedName("dismissal-info")
@Expose
private String dismissalInfo;
@SerializedName("batsman")
@Expose
private String batsman;
@SerializedName("pid")
@Expose
private Integer pid;
@SerializedName("detail")
@Expose
private String detail;

public DismissalBy getDismissalBy() {
    return dismissalBy;
}

public void setDismissalBy(DismissalBy dismissalBy) {
    this.dismissalBy = dismissalBy;
}

public String getDismissal() {
    return dismissal;
}

public void setDismissal(String dismissal) {
    this.dismissal = dismissal;
}

public String getSR() {
    return sR;
}

public void setSR(String sR) {
    this.sR = sR;
}

public String get6s() {
    return _6s;
}

public void set6s(String _6s) {
    this._6s = _6s;
}

public String get4s() {
    return _4s;
}

public void set4s(String _4s) {
    this._4s = _4s;
}

public String getB() {
    return b;
}

public void setB(String b) {
    this.b = b;
}

public String getR() {
    return r;
}

public void setR(String r) {
    this.r = r;
}

public String getDismissalInfo() {
    return dismissalInfo;
}

public void setDismissalInfo(String dismissalInfo) {
    this.dismissalInfo = dismissalInfo;
}

public String getBatsman() {
    return batsman;
}

public void setBatsman(String batsman) {
    this.batsman = batsman;
}

public Integer getPid() {
    return pid;
}

public void setPid(Integer pid) {
    this.pid = pid;
}

public String getDetail() {
    return detail;
}

public void setDetail(String detail) {
    this.detail = detail;
}

}

java类的解雇

public class DismissalBy implements Serializable {

@SerializedName("name")
@Expose
private String name;
@SerializedName("pid")
@Expose
private String pid;

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public String getPid() {
    return pid;
}

public void setPid(String pid) {
    this.pid = pid;
}

}

我该如何解决这个问题？ 任何帮助将不胜感激

Answer 1

在您的JSON对象中，有一个

"dismissal-by": {
          "name": "LK Bell",
          "pid": "878025"
        },

您不能像这样使用它，因为您将其声明为数组，因此它应该保持相同的类型，因为您需要将其更改为类似

  "dismissal-by"":[
    {
          "name": "LK Bell",
          "pid": "878025"
        }
    ]

，

要解决此问题，您需要手动解析所有JSON，例如

Json json = new Json(string);
try{
json.getJsonArray("dismissal-by");
}catch(IllegalStateException e)
{
json.getObject("dismissal-by");  
}

Answer 2

该JSON无效...因此com.google.gson.JsonSyntaxException 。

它必须以{开头，并在"title": "Lancashire Thunder Innings" ，缺少}] 。

在那里您可以自己检查： https : //jsonlint.com

Answer 3

被解雇的时间是数组格式（以[开头，以]结束），而有一段时间是Json对象{}，那么最好从API开发人员那里解决。 或者，您可以将其声明为String，然后在需要时进行解析。

public class Score__ implements Serializable {

@SerializedName("dismissal-by")
@Expose
private String dismissalBy;}
