Gson 问题

[helloha2013]

假设与如下json，使用Gson读取

{
"code":100,
"griddata":[
{"img":"http:\/\/img.netbian.com\/file\/20140405\/fa129372a26730ea8030dbbb392d6ac7.jpg"},
{"img":"http:\/\/img.netbian.com\/file\/2016\/0529\/849bfad06e44e67364752eee6a382448.jpg"},
{"img":"http:\/\/img.netbian.com\/file\/20140405\/fa129372a26730ea8030dbbb392d6ac7.jpg"}
]
}

对应的bean是

public class TTTT {
 
    /**
     * code : 100
     * griddata : [{"img":"http://img2.kanrenti.org/photoL/7254/01.jpg"},{"img":"http://img2.kanrenti.org/photoL/7254/02.jpg"},{"img":"http://img2.kanrenti.org/photoL/7254/03.jpg"}]
     */
 
    private int code;
    /**
     * img : http://img2.kanrenti.org/photoL/7254/01.jpg
     */
 
    private List<GriddataEntity> griddata;
 
    public int getCode() {
        return code;
    }
 
    public void setCode(int code) {
        this.code = code;
    }
 
    public List<GriddataEntity> getGriddata() {
        return griddata;
    }
 
    public void setGriddata(List<GriddataEntity> griddata) {
        this.griddata = griddata;
    }
 
    public static class GriddataEntity {
        private String img;
 
        public String getImg() {
            return img;
        }
 
        public void setImg(String img) {
            this.img = img;
        }
    }
}

然后使用Gson的fromJson方法读取，如
Type lt = new TypeToken<List<TTTT>>() {}.getType();
List<TTTT> tmp1 = g.fromJson(response, lt); //此句报错
或者
TTTT tmp1=g.fromJson(response,TTTT.class); //此句报错

都报：Caused by: java.lang.IllegalStateException: Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2
请问，Gson如何读取这样啦的bean？

[柒加伊]

json 解析可以使用内部类么, 这个我还真没用过, 是不是这个引起的呢.

[秃头地中海]

应该是你解析的数据有问题 代码不全 打印response看看是不是就是数组

[jklwan]

用TTTT tmp1=g.fromJson(response,TTTT.class);这个解析。 Expected BEGIN_ARRAY but was BEGIN_OBJECT，就是说需要的是array但是数据是bean，应该是数据问题 打印下数据看是否正确。

谢谢大家，给分了！
