BCOS:sample示例项目导入Eclipse步骤及遇到的问题

zhuangjinxin commented 7 years ago

项目导入过程：

打开Eclipse,File->Import->General->Existing Project into Workspace->选择sample项目->Finish完成！

如果Eclipse项目比较多，可以在导入项目前或导入项目中建立java workset分组

问题1:

问题描述：导入后一片红，缺少web3j的main包和extension包！ 解决办法：右击项目名sample->Build Path->Configure Build Path...->选Libraries->Add JARs->选择sample项目sample/lib目录下的三个包:DfsSDK.jar、web3j-2.1.0.jar和web3j-2.1.0-extension.jar点Ok->点Apply应用->点Ok确认；项目里的红杠消除，依赖包全部导入！

问题2:

问题描述：运行项目报错The project: web3j-v2.0.1_src which is referenced by the classpath, does not exist. 解决办法：右键项目名simple->Build Path->Configure Build Path->Projects->remove web3j相关的两个项目->Ok确认！

之后，再Run运行Main.java即可！

error in deploy contract !!!

zhuangjinxin commented 7 years ago

@黄高峰-矩阵元-深圳链接超时，你可以在浏览器输入地址端口试试，是不是服务节点没起来，或防火墙配置不对

zhuangjinxin commented 7 years ago

连接超时，防火墙设置的问题；systemctl stop firewalld.service关闭防火墙。如果节点正常启动，在浏览器中访问地址:端口，会提示Not allowed HTTP Method.
