fastjson map转string 文心快码BaiduComate 要将Map 对象转换为 String,你可以使用 Fastjson 库提供的序列化方法。以下是详细的步骤和代码示例: 导入Fastjson 库: 首先,你需要在项目中引入 Fastjson 库。如果你使用的是 Maven 项目,可以在 pom.xml 文件中添加以下依赖: xml <dependency> <groupId>...
String jsonString=JSON.toJSONString(map); System.out.println("json字符串是:"+jsonString); } 运行结果: 运行结果: json字符串是:{"name":"cool_summer_moon","age":24} 5、Map 转 Json @Testpublicvoidtest(){ Map<String,Object> map =newHashMap<>(); map.put("age", 24); map.put("nam...
Bar> map =newHashMap<String, Bar>(); map.put("a",newBar()); map.put("b",newBar()); map.put("c",newBar()); String json = JSON.toJSONString(map,true); System.out.println(json);//JSON -> MapMap<String,Bar
//Map<String, String> aliasMap, //Map<String, Field> fieldCacheMap, // boolean sorted, // PropertyNamingStrategy propertyNamingStrategy // ) {/*省略*/ Method[] methods = clazz.getMethods();/*省略*/for (Method method : methods) {String methodName = method....
TimeMillis());Stringstring=json.toString();System.out.println(string);Map<String,String>map=JSON.parseObject(string,newTypeReference<Map<String,String>>(){});System.out.println(map);{"name":"jacky","time":1563957295755,"age":23}{name=jacky,time=1563957295755,age=23}int和long都会转为String...

private String code; private String message; private String success; //Data集合 private List<Data> data = new ArrayList<>(); public Error() { } public Error(String code, String message, String success, List<Data> data) { this.code = code; ...
Map<String, Object> itemMap = JSONObject.toJavaObject(itemJSONObj, Map.class); /** itemJSONObj JSONObject**/ 5. JSONObject 转 JavaBean Student student = JSON.parseObject(JSONObjectStr, new TypeReference<Student>() {}); //因为JSONObject继承了JSON,所以这样也是可以的 ...
第二个方法是createInstance(Map<String, Object> map, ParserConfig config)，它的场景是，如果要反序列...
1.String转Map Map infoMap=JSONObject.parseObject(info,Map.class); 2.String转json对象 JSONObject jsonObject=JSONObject.parseObject(data); 3.String转类对象 contractInfo=JSONObject.parseObject(contractStr, ContractInfo.class); 4.map转类对象
