1、使用fastJson 将String转 map: String out; Object succesResponse = JSON.parse(out); //先转换成Object Map map...= (Map)succesResponse; //Object强转换为Map 2、String 转 java 对象 fastjson 应用 string字符串转换成java对象或者对象数组...private String b; public String getB() { return b;...
JavaScript有7种类型:Boolean、Number、String、Undefined、Null、Object,以及ES6新增的Symbol 这7种TypeScript全都支持: // JavaScript支持的7种类型 let isDone: boolean = false; // 布尔值 let decimal: number = 6; // 数值 let color: string = 'blue'; // 字符串 ...
interfaceCanCheck{checkThing:(x:string)=>boolean;} and implement it with an object: constobj={checkThing:(sn:string|number)=>{returntrue;}}objsatisfiesCanCheck;// OK A common confusion is to say that sincestring | numberis a bigger type thanstring, this program should be rejected, since...

type Record<K extends string | number | symbol, T> = { [P in K]: T; } 所以,AnyObject 其实就是一个值为any类型的对象。 把参数数组赋值一份后,取出自定义处理函数,通过 reduce 循环设置默认值。assignObjectDeep 实现的是给一个对象递归设置默认值的逻辑。 const assignObjectDeep = <TObj extends...
