报错信息com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 7 column 10
import java.io.Serializable; import java.util.List; import com.google.gson.Gson; public class GsonTest { public static List<ArticleImage> articleimglist; public static void main(String[] args) { String str = "{\"age\":23,\"name\":\"dsfds\", \"articleimglist\":\"\"}"; /***String str = "{\"age\":23,\"name\":\"dsfds\", \"articleimglist\":null}";***/ /****把list集合变量设置为null ****/ Gson gson = new Gson(); Article ar = gson.fromJson(str, Article.class); System.out.println(ar.age); System.out.println(ar.name); } } class Article { public int age; public String name; public List<ArticleImage> articleimglist; } class ArticleImage implements Serializable{ private static final long serialVersionUID = 6762300101092577096L; public String image; }总结：（1）碰到这个问题的时候，比较郁闷，使用HiJson等解析工具没有报错。但是实际代码中总是报错。（这个很坑，然自己一时没有想明白） （2）服务器端的数据类型应该定义严谨一些，要不然很容易出现错误。 （3）Expected BEGIN_ARRAY but was STRING at line 1 column 45.以后碰到这种错误就大概知道是啥意思了转载http://blog.csdn.net/zhuhai__yizhi/article/details/41249155
