json格式的字符串递归解析

Question

public class LibraryGdsFaxingCatgDTO {
    /**
     * 层级展示
     */
    private String hierarchy;
    /**
     * 发行分类总数据
     */
    private List<LibraryDataDTO> dataList;


    public String getHierarchy() {
        return hierarchy;
    }

    public void setHierarchy(String hierarchy) {
        this.hierarchy = hierarchy;
    }

    public List<LibraryDataDTO> getDataList() {
        return dataList;
    }

    public void setDataList(List<LibraryDataDTO> dataList) {
        this.dataList = dataList;
    }

public class LibraryDataDTO {
    /**
     * 首页分类名称
     */
    private String name;
    /**
     * 分类编码
     */
    private String code;
    /**
     * 是否展示
     */
    private String isShow;
    /**
     * 递归子类
     */
    private List<LibraryDataDTO> childrenList;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public String getIsShow() {
        return isShow;
    }

    public void setIsShow(String isShow) {
        this.isShow = isShow;
    }

    public List<LibraryDataDTO> getChildrenList() {
        return childrenList;
    }

    public void setChildrenList(List<LibraryDataDTO> childrenList) {
        this.childrenList = childrenList;
    }

String data = {"hierarchy":"4","data":[{"name":"教材","code":"4009,4011,4012","isShow":"1","children":[{"name":"配套教材","code":"4009","children":[],"isShow":"0"},{"name":"学历教育教材","code":"4011","children":[],"isShow":"0"},{"name":"培训教材","code":"4012","children":[],"isShow":"0"}]},{"name":"参考书","code":"4006","isShow":"1","children":[{"name":"参考书","code":"4006","children":[],"isShow":"0"}]},{"name":"科普书","code":"4006","isShow":"1","children":[{"name":"科普","code":"4017","children":[],"isShow":"0"}]},{"name":"考试用书","code":"4006","isShow":"1","children":[{"name":"考试用书","code":"4010","children":[],"isShow":"0"}]}]}

这个字符串递归解析最终结果为 LibraryGdsFaxingCatgDTO怎么实现？帮忙看一下

Answer 1

LibraryGdsFaxingCatgDTO 中的dataList与String s的data字段一致有么都是data，有么dataList；同理LibraryDataDTO 中的childrenList与String s的children也是要一致的。
然后使用fastjson中的

LibraryGdsFaxingCatgDTO dto = JSONObject.parseObject(s,LibraryGdsFaxingCatgDTO.class);
