Spring Boot

JSON-RPC server is integrated with Spring Boot.

The entry point is the module io.yupiik.uship:jsonrpc-spring. Once added you can:

  • mark your application with @EnableJsonRpc,

  • implement JSON-RPC methods using beans marked with @JsonRpc and methods with @JsonRpcMethod,

  • configure the base url of the OpenRPC value using jsonrpc.baseUrl and binding url of the JSON-RPC endpoint with jsonrpc.binding in your application.properties (default uses the spring web server).

Here is a sample:

@EnableJsonRpc
@SpringBootApplication
public class MyApp {
    @Bean
    MyEndpoints endpoints() {
        return new MyEndpoints();
    }
}

@JsonRpc
public class MyEndpoints {
    @JsonRpcMethod(name = "reverse")
    public String reverse(@JsonRpcParam(value = "in") final String input) {
        return new StringBuilder(input).reverse().toString();
    }

    @JsonRpcMethod(name = "header")
    public String header(@JsonRpcParam(value = "name") final String name,
                         final HttpServletRequest request /*important: se jakarta one*/) {
        return request.getHeader(name);
    }
}
