Question

你能帮我在java类中如何将String转换为json。还有另一件事是如何将 json 值存储在另一个字符串中。下面维护我使用哪个字符串将字符串转换为 json。

String str1 = {"documentType":"employment","place_address":"Yes","reportingTo":"1","bonusAmount":"3","EmployerPostalCode":"13","EmployeeCity":"17","EmployerName":"7","EmployerCity":"10","EmployerProvince":"11","natureDescription":" 6","EmployerAddress1":"8","EmployerAddress2":"9","paidMethod":"Yearly","EmployeeName":"14","EmployeeAddress2":"16","EmployerCountry":"12","timeEmployeeWorking":"4","EmployeePostalCode":"20","job_Title":"5","EmployeeAddress1":"15","EmployeeCountry":"19","EmployerPhone":"897564564","EmployeeProvince":"18","paidAmount":"2","EmployerBusinessType":"Sole Proprietorship","start_date":"2015-10-10","EmployerEmail":"abhi@gmail.com","fileUploadErrorMessage":""}

这是键值对中数据所在的字符串。请建议如何将其转换为字符串我只想要字符串形式的值。

Answer 1

这是一个使用 Java 字符串表示的 JSON 示例。

String str1 = "{\"type\":\"employment\",\"addr\":\"Yes\",\"reportingTo\":\"1\"}";

请注意，JSON 中的双引号需要在字符串文字中进行转义。

numerous Java JSON parser libraries 会将 JSON 文本（如上面的字符串）转换为内存中的对象。一个简单的就是"org.json" library。）
