JSON-RPC for Java with Spring

1. Add Dependency

We use the jsonrpc4j library, the latest version is 1.5.3 https://github.com/briandilley/jsonrpc4j

2. Create AutoJsonRpcServiceImplExporter

3. Create ServerAPI interface

4. Create ServerAPI implementation

5. Deploy to glassfish server

6. Use Postman to test API

6.1. Test 'multiplier' method

Send POST request with 'application/json' to endpoint 'http://localhost:8080/jsonrpc4j/api'

6.2. Test 'printPerson' method

6.3. Test 'printPersons' method

Send POST request with 'application/json' to endpoint 'http://localhost:8080/jsonrpc4j/api'

Download Source Code

7. Implement your own JSON RCP Client

It is quite simple to write a controller to invoke JSON-RPC API by using JsonRpcRestClient Download JSON RCP Client Source Code

8. Deploy JSON RCP Client and Test

8.1. Deploy JSON RPC Client

'SpringJsonRPCClient' can be deployed in the same Glassfish with package 'SpringJsonRPCExample'

8.2. Test JSON RPC Client

Enter the appropriated urls to web browser to invoke API

http://localhost:8080//jsonrpc4j-client/multiplier?a=1111111&b=1111111

http://localhost:8080//jsonrpc4j-client/printperson

http://localhost:8080//jsonrpc4j-client/printpersons
