Description

This sample illustrates how to use JSON Patch,JSON Merge Patch and JSON Pointer to update a JSON document.

Client send patch request to server like below: 

JSON Patch:
PATCH /jsonp/ProcessUser HTTP/1.1
Host: localhost:7001
Content-Length: 102
Content-Type: application/json-patch+json
Content: [{"op":"replace","path":"/nickName","value":"Tom oracle"},{"op":"replace","path":"/age","value":"33"}]

JSON Merge Patch:
PATCH /jsonp/ProcessUser HTTP/1.1
Host: localhost:7001
Content-Length: 35
Content-Type: application/merge-patch+json
Content: {"nickName":"Tom merge","age":"34"}

Server side will use JsonPatch or JsonMergePatch to update json document like below: 

//Json Patch
JsonObject oldUser = Json.createReader(new StringReader(userJsonString)).readObject(); // The target to be patched
JsonArray patch = Json.createReader(new StringReader(patchJsonString)).readArray();  ; // JSON Patch
JsonPatch jsonpatch = Json.createPatch(patch);
JsonObject result = jsonpatch.apply(oldUser);

//Json Merge Patch
JsonValue oldUser = Json.createReader(new StringReader(userJsonString)).read(); // The target to be patched
JsonValue mergePatchJson = Json.createReader(new StringReader(patchJsonString)).read(); // JSON Merge Patch
JsonMergePatch mergePatch = Json.createMergePatch(mergePatchJson);
JsonValue result = mergePatch.apply(oldUser);

Building and Configuring the Example

Prerequisites

Before working with this example:

  1. Install WebLogic Server, including the examples.
  2. Start the Examples server.
  3. Set up your environment.

Build and Deploy the Example

This sample is already built and deployed in the wl_server WebLogic Server Examples domain, so you can skip these steps and proceed directly to running the example.

  1. Change to the D:\Oracle\Middleware\Oracle_Home\wlserver/samples/server/examples/src/examples/javaee8/jsonp directory.
  2. Execute the following command:

    ant build

    to compile and stage the example.
  3. Execute the following command:

    ant deploy

    to deploy the example in the wl_server WebLogic Server Examples domain.

Running the Examples

  1. Complete the steps in the "Building and Configuring the Example" section.
  2. Execute the following command:

    ant run

    which opens your default browser to display the json-p 1.1 new features sample application home page.

    3. Input the nick name and age, then click the save button. You can see the following message on the console.
