源：

{    "mapBean": {        "mapBean-key1": {            "id": "1",            "name": "cyy1"        },        "mapBean-key2": {            "id": "2",            "name": "cyy2"        }    },    "mapString": {        "mapString-key1": "values1",        "mapString-key2": "values2"    }}

解析Bean：

public static class Bean{    private String id;    private String name;        public Bean(){            }    public Bean(String id, String name){        this.id = id;        this.name = name;    }    public String getId() {        return id;    }    public void setId(String id) {        this.id = id;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }}public static class BeanMap{   private  Map<String, String> mapString;    private  Map<String, Bean> mapBean;    public Map<String, String> getMapString() {        return mapString;    }    public void setMapString(Map<String, String> mapString) {        this.mapString = mapString;    }    public Map<String, Bean> getMapBean() {        return mapBean;    }    public void setMapBean(Map<String, Bean> mapBean) {        this.mapBean = mapBean;    }}

生成：

Map<String, String> mapString = new HashMap<>();Map<String, Bean> mapBean = new HashMap<>();mapString.put("mapString-key1", "values1");mapString.put("mapString-key2", "values2");mapBean.put("mapBean-key1", new Bean("1", "cyy1"));mapBean.put("mapBean-key2", new Bean("2", "cyy2"));BeanMap beanMap = new BeanMap();beanMap.setMapBean(mapBean);beanMap.setMapString(mapString);LogUtil.i("test-map", JsonUtil.toJson(beanMap));
