How To Escape Json String Inward Java- Eclipse Ide Tips

While working or JSON parsing inward Java application it's quite mutual to merely re-create glue a JSON String from some resources e.g. a RESTful spider web service too and then exercise the Jackson library to parse the JSON. This is the quickest agency to attempt too acquire parsing JSON string inward Java, but the principal work amongst this approach is that the JSON String also includes double quotes "" which is also used for enclosing String literals inward Java. Since JSON String itself contains double quotes, when you lot merely re-create glue them inward your IDE or Java source file, the didn't function equally expected. If you lot remember, if your String contains double quotes too then those postulate to move escaped when you lot are pasting them equally String literals inward your Java code.

You tin hand notice escape String inward Java past times putting a backslash inward double quotes e.g. " tin hand notice move escaped equally \" if it occurs within String itself. This is ok for a modest JSON String but manually replacing each double quotes amongst escape graphic symbol for fifty-fifty a medium size JSON is fourth dimension taking, boring, too error-prone. So If you lot accept a JSON String which you lot postulate to parse inward Java using Jackson, what volition you lot do?

Well, at that topographic point are multiple solution e.g. you lot tin hand notice salve that String inward a file too and then read the file inward your programme instead of re-create pasting String into your Java code, or, you lot tin hand notice straight download from the cyberspace past times using HttpConnection utility of Apache Commons, though this required additional dependency inward your Java application too may slowly downward your testing.

You tin hand notice fifty-fifty exercise text editors similar Notepad++, EditPlus, or Sublime (See my Java tools) which supports regex searching to supercede all double quotes amongst escape characters earlier copying the String literal into Java code, but this is over again fault prone if your JSON string contains business breaks too novel business because those needs to escaped manually.

How to Escape JSON String inward Java Source Code using Eclipse

The quickest too the best agency I institute is to leverage Eclipse's capability to Escape text when pasting into a String literal. This characteristic tin hand notice move enabled from a setting too and then Eclipse volition escape all double quotes, business breaks, novel lines or whatsoever other graphic symbol which postulate escaping automatically. This tin hand notice salve you lot tons of fourth dimension too tin hand notice speed upward your learning too testing.

Here are the exact steps to enable this String escape setting into Eclipse IDE:

1. Open Eclipse IDE
2. Go to Windows  --> Preferences --> Java --> Editor --> Typing
3) Check the checkbox "Escape text when pasting into a String literal" on department "In String literals.

Here is how your settings should aspect similar inward Eclipse IDE:

Once you lot did this, Eclipse volition escape String if it contains whatsoever characters which postulate escaping. Let's come across an event now.

{ "name": "John", "email": "john.doe@gmail.com", "age": 29, "phone" : 5168161922, "city" : "NewYork", "hasCreditCard": faux }

Here all those double quotes around attributes postulate to move escaped but when you lot glue this JSON String inward Eclipse, it volition automatically escape those for you lot equally shown below:

You tin hand notice come across how Eclipse has escaped the JSON easily. This is an awesome characteristic of Eclipse IDE too you lot should enable it if you lot are working amongst JSON inward Java.


That's all close how to escape JSON String inward Java using Eclipse IDE. This is a existent fourth dimension saver tip which you lot volition appreciate every fourth dimension you lot postulate to glue a JSON String into Java code. The Eclipse IDE is total of such gems too but many of us didn't exercise Eclipse upward to its total potential. Many programmers don't fifty-fifty know essential Eclipse shortcuts too debugging tips, which tin hand notice over again salve a lot of fourth dimension spell reading, writing, or troubleshooting Java code.
