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？
