将深度嵌套的json转换为java对象，反之亦然

将深度嵌套的json转换为java对象，反之亦然

您可以通过以下方式实现Google的GSON库。已经显示了一个示例类，您可以进一步对其进行修改。

类-提案汇总

package com.test;import java.util.Map;public class ProposalAggregation {private Map<String, Map<String, String>> Buys;private Map<String, Map<String, String>> Sells;private Map<String, Map<String, String>> TAChanges;public Map<String, Map<String, String>> getBuys() {    return Buys;}public void setBuys(Map<String, Map<String, String>> buys) {    Buys = buys;}public Map<String, Map<String, String>> getSells() {    return Sells;}public void setSells(Map<String, Map<String, String>> sells) {    Sells = sells;}public Map<String, Map<String, String>> getTAChanges() {    return TAChanges;}public void setTAChanges(Map<String, Map<String, String>> tAChanges) {    TAChanges = tAChanges;}public String toString() {    return "BUYS=" + this.Buys + " nSELLS=" + this.Sells + " nTACHANGES=" + this.TAChanges;}

}

测试主类 请注意，我已经修改了

key

名称，只是为了验证转换是否正确。

package com.test;import java.io.BufferedReader;import java.io.FileReader;import java.io.IOException;import com.google.gson.Gson;public class TestClass {    public static void main(String[] args) {        Gson gson = new Gson();        try { String jsonString = " { 'Buys': { 'bHeading1': { 'bkey1': 'value1', 'bkey2': 'value2', 'bkey3': 'value3' }, 'bbHeading2': { 'bbkey1': 'value1', 'bbkey2': 'value2', 'bbkey3': 'value3' } }, "         + "'Sells': { 'sHeading1': { 'skey1': 'value1', 'skey2': 'value2', 'skey3': 'value3' }, 'ssHeading2': { 'sskey1': 'value1', 'sskey2': 'value2', 'sskey3': 'value3' } }, "         + "'TAChanges': { 'Heading1': { 'key1': 'value1', 'key2': 'value2', 'key3': 'value3' }, 'Heading2': { 'key1': 'value1', 'key2': 'value2', 'key3': 'value3' } }, 'Existing': { 'Heading1': { 'key1': 'value1', 'key2': 'value2', 'key3': 'value3' }, 'Heading2': { 'key1': 'value1', 'key2': 'value2', 'key3': 'value3' } }, 'Proposed': { 'Heading1': { 'key1': 'value1', 'key2': 'value2', 'key3': 'value3' }, 'Heading2': { 'key1': 'value1', 'key2': 'value2', 'key3': 'value3' } }, 'PIAChanges': { 'Heading1': { 'key1': 'value1', 'key2': 'value2', 'key3': 'value3' }, 'Heading2': { 'key1': 'value1', 'key2': 'value2', 'key3': 'value3' } } }"; // convert to java class ProposalAggregation obj = gson.fromJson(jsonString, ProposalAggregation.class); System.out.println("OBJECT : " + obj); // convert to json String jsonStringFromObj = gson.toJson(obj); System.out.println("JSON : " + jsonStringFromObj);        } catch (Exception e) { e.printStackTrace();        }    }}

这是输出。
