如何使用Java/Jackson对JSON字符串进行转义? [英] How do I unescape a JSON String using Java/Jackson?

问题描述

我正在使用Jackson 2.4.3版将复杂的Java对象转换为String对象，因此下面是我得到的输出.输出如下所示(Fyi-我只是打印了输出的一部分)

I am using Jackson version 2.4.3 for converting my complex Java object into a String object, so below is what I'm getting in output. The output is like below (Fyi - I just printed some part of the output)

"{\"FirstName\":\"John \",\"LastName\":cena,\"salary\":7500,\"skills\":[\"java\",\"python\"]}";

这是我的代码(PaymentTnx是一个复杂的Java对象)

Here is my code (PaymentTnx is a complex Java object)

ObjectMapper mapper = new ObjectMapper();
mapper.setVisibility(PropertyAccessor.FIELD, Visibility.ANY);
String lpTransactionJSON = mapper.writeValueAsString(paymentTxn);

我不想在我的JSON字符串中看到\斜线.我需要怎么做才能得到如下所示的字符串:

I don't want to see \ slashes in my JSON string. What do I need to do to get a string like below:

"{"FirstName":"John ","LastName":cena,"salary":7500,"skills":["java","python"]}";

推荐答案

String test = "{\"FirstName\":\"John \",\"LastName\":cena,\"salary\":7500,\"skills\":[\"java\",\"python\"]}";
        System.out.println(StringEscapeUtils.unescapeJava(test));
