首先自然想到封装成JavaBean。

注意点：

1、内部嵌套的类必须是static的，要不然解析会出错；

2、类里面的属性名必须跟Json字段里面的Key一模一样；

3、因为Json字段里面的Key存在中文，所以必须在相应的字段上使用@SerializedName(“中国画”)注解，给Key取别名。

4、内部嵌套用{}嵌套的就定义为 public ChinaPicture chinaPicture，用[]括起来的部分是一个List，所以定义为 public List years。

5、如果不想写get和set方法，只需要将字段定义成public。

public class JsonBean {
public int ret;
public Response response;

public static class Response {
public TagCategory tag_category;

public static class TagCategory {

@SerializedName("中国画")
