Spring WebFlux and Corda

This project uses Spring WebFlux to stream the progress of a simple flow and updates of states that are saved to the vault.

Structure:

• app: Spring code
• cordapp: Corda application code
• contracts-and-states: Contracts and states

Pre-requisites:

See https://docs.corda.net/getting-set-up.html.

Usage

Running the nodes:

Run the following gradle task to build the Corda nodes

• Windows: gradlew.bat deployNodes
• Unix: ./gradlew deployNodes

Once built, go to the build/nodes directory and run ./runnodes

Running the webservers:

Once the nodes are running, you can start the node webserver from the command line:

• Windows: gradlew.bat runPartyAServer
• Unix: ./gradlew runPartyAServer

Both approaches use environment variables to set:

• server.port, which defines the HTTP port the webserver listens on
• config.rpc.*, which define the RPC settings the webserver uses to connect to the node

Interacting with the nodes:

Send a message via a post request

`localhost:10011/messages`

with a body like

{
    "recipient": "O=PartyB,L=London,C=GB",
    "contents": "this is a temporary message"
}
