Provided Spring MVC services and spring boot starters based on fabric-gateway-java, more info can be found from https://ecsoya.github.io/fabric/(中文).
Build your fabric network with Hyperledger Fabric 1.4.0 +.
Optional, install the default common Chaincode.
fabric-gateway-spring-boot-starter: A spring MVC boot starter.fabric-explorer-spring-boot-starter: A simple fabric explorer starter.Firstly, add the following dependency to your project's pom.xml file:
<dependency>
<groupId>io.github.ecsoya</groupId>
<artifactId>fabric-gateway-spring-boot-starter</artifactId>
<version>1.0.5</version>
</dependency>or
<dependency>
<groupId>io.github.ecsoya</groupId>
<artifactId>fabric-explorer-spring-boot-starter</artifactId>
<version>1.0.5</version>
</dependency>Secondly, configure fabric network in application.yml
# Fabric Network Configure
spring:
fabric:
chaincode:
identify: your chaincode id
name: Common chaincode
version: 1.0
channel: your channel name
organizations:
- org1
- org2
name: your fabric network name
gateway:
wallet:
identify: admin
network:
file: network/connection.yml //your fabric network config file.
name: fabric network name
# Fabric explorer

Finally, enjoy to use the following spring components:
FabricContext: wrapper class for fabric gateway.IFabricInfoService: query fabric infos such as blocks, transaction and so on.IFabricService: CRUD FabricObject if you install the default common Chaincode.@Autowired
private FabricContext fabricContext;The Fabric Network Config File is the core configuration file of fabric network, both FabricContext and Gateway are built with this kind of file. It holds details of network and channel configurations typically loaded from an external config file.
Please look at the org.hyperledger.fabric.sdk.NetworkConfig to get more details.
You can also look at my project Fabric Network Builder to learn how to create a fabric network config file.
The default common chaincode provided useful functions such as create, get, update, query. It used a CompositeKey with id and type to identify different objects, it also support pagination query.
The chaincode source can be found from here.
This will help you to build a simple fabric explorer with few codes.
