参照：[https://blog.csdn.net/tianshuhao521/article/details/100538262][https_blog.csdn.net_tianshuhao521_article_details_100538262] 已完成fabric1.4.3网络环境搭建。

1、清空环境

清空所有docker容器：\# docker rm -f $(docker ps -aq)

清空所有缓存网络：\# docker network prune

若已运行过此教程需要删除chaincode镜像，若是第一次运行不需要：

\# docker rmi dev-peer0.org1.example.com-fabcar-1.0-5c906e402ed29f20260ae42283216aa75549c571e2e380f3615826365d8269ba

2、启动网络：

\# cd /opt/gopath/src/github.com/hyperledger/fabric/scripts/fabric-samples/fabcar

\# ./startFabric.sh

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RpYW5zaHVoYW81MjE_size_16_color_FFFFFF_t_70 1][]

查看容器：\# docker ps

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RpYW5zaHVoYW81MjE_size_16_color_FFFFFF_t_70 2][]

3、我用java去测试，实现注册用户等功能，网络启动之后会提示，进入java文件夹，然后执行mvn test命令，所以这里要确保已安装jdk和mvn。

注释：这里可能fabric-gateway-java的包存在问题，contract.submitTransaction()方法提交报错，所以我这里先注释掉，只执行查询操作，不执行创建和更改操作。

4、\# cd /opt/gopath/src/github.com/hyperledger/fabric/scripts/fabric-samples/fabcar/java/src/main/java/org/example

\# vim ClientApp.java

修改代码如图：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RpYW5zaHVoYW81MjE_size_16_color_FFFFFF_t_70 3][]

退出vim

\# cd  /opt/gopath/src/github.com/hyperledger/fabric/scripts/fabric-samples/fabcar/java

\# mvn test

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RpYW5zaHVoYW81MjE_size_16_color_FFFFFF_t_70 4][]

可以看到打印的信息，因为我之前创建过user，所以打印出来已存在，另外执行的queryAllCars()方法和queryCar()方法的查询结果也已经打印出来。
