Unit Test

Implementation service

1 change maven pom file for required dependency. For todo-list eventuate example project, following are required dependencies:

   <dependency>
        <groupId>com.networknt</groupId>
        <artifactId>eventuate-common</artifactId>
    </dependency>
    <dependency>
        <groupId>com.networknt</groupId>
        <artifactId>eventuate-client</artifactId>
    </dependency>
    <dependency>
        <groupId>com.networknt</groupId>
        <artifactId>eventuate-todo-common</artifactId>
    </dependency>
    <dependency>
        <groupId>com.networknt</groupId>
        <artifactId>eventuate-todo-command</artifactId>
    </dependency>

1. Implement service handler classes and test classes:

To consist with Restful microservice, Hybrid service use RPC call with Json format input and output. In the handler class, we pass the input object as below:

---

     JsonNode inputPara =Config.getInstance().getMapper().valueToTree(input);

     TodoInfo todo = new TodoInfo();
     todo.setTitle(inputPara.findPath("title").asText());
     todo.setCompleted(inputPara.findPath("completed").asBoolean());
     todo.setOrder(inputPara.findPath("order").asInt());

---

Please refer github source code for detail implementation:

https://github.com/networknt/light-eventuate-example/tree/master/todo-list/command-hybridservice https://github.com/networknt/light-eventuate-example/tree/master/todo-list/query-hybridservice

Setup service

1. Build project: cd light-eventuate-example/todo-list mvn clean install

2. Go to command server module in light-eventaute-4j project.

change com.networknt.server.StartupHookProvider by adding following line:

# registry all service handlers by from annotations com.networknt.rpc.router.RpcStartupHookProvider com.networknt.eventuate.cdcservice.CdcStartupHookProvider

RpcStartupHookProvider is used for hybrid service to register and process RPC handlers CdcStartupHookProvider: eventuate sourcing run CDC service on command side to convert events in event store

1. Go to query server module in light-eventaute-4j project.

change com.networknt.server.StartupHookProvider by adding following line:

# config event handle registration com.networknt.eventuate.client.EventuateClientStartupHookProvider

EventuateClientStartupHookProvider: eventatuate event handler startup provide. query side service need run defined event handler to process event.

1. Prepare resource config in docker folder

Add and modify required config files into light/eventuate-4j/docker folder for testing
