Copy fabric network `crypto-config` to `src/main/resources/crypto-config`. 8 | 9 | 2. Config organiztion, peer and IP address in `NetworkGenerator`. 10 | 11 | 3. Run the `NetworkGenerator`, and you'll get the fabric network config file from `src/main/resources/network`. 12 | 13 | 4. Run `NetworkTest` to test it. 14 | 15 | 16 | ### 中文使用 17 | 18 | 1. 将fabric网络的`证书文件`拷贝到`resource`目录下。 19 | 2. 在`NetworkGenerator`中配置`组织`、`peer`的IP地址。 20 | 3. 运行`NetworkGenerator`，生成fabric的网络连接文件`connection-*.yml`。 21 | 4. 通过`NetworkTest`测试。 22 | 23 | -------------------------------------------------------------------------------- /fabric-network-builder-local/pom.xml: -------------------------------------------------------------------------------- 1 | 2 | 4.0.0 3 | 4 | io.github.ecsoya 5 | fabric-network-builder 6 | 1.0.0-SNAPSHOT 7 | 8 | fabric-network-builder-local 9 | fabric-network-builder-local 10 | Localhost fabric network builder 11 | -------------------------------------------------------------------------------- /fabric-network-builder-local/src/main/java/org/ecsoya/fabric/builder/NetworkBuilder.java: -------------------------------------------------------------------------------- 1 | package org.ecsoya.fabric.builder;
