 3 | 关于代码介绍方法，可以去看我的[博客](https://www.cnblogs.com/xiaohuiduan/category/1635542.html)。里面介绍了一些功能的实现思路和方法，以及使用到的一些库的介绍。

12 | # 使用方法
13 | 
14 | 
15 | 
16 | ## 打包
17 | 
18 | 首先在maven中更改jar包生成位置
19 | 
20 | ![](imgs/image-20200616110901064.png)
21 | 
22 | 然后使用命令生成jar包
23 | 
24 | ```bash
25 | mvn package
26 | ```
27 | 
28 | ## 运行方法
29 | 
30 | 在**IDEA运行**着将第二块区域进行注释（第一块区域不要注释），使用jar包运行则将第一块区域进行注释（第二块区域不要注释）
31 | 
32 | ![](imgs/image-20200616113250619.png)
33 | 
34 | ### 包运行方法
35 | 
36 | ```bash
37 | java -jar 包名 ip地址 端口号 序号 文件保存位置
38 | ```
39 | 
40 | - ip地址和端口号代表节点作为server需要占用ip和端口号
41 | - 序号：节点的序号，必须独一无二
42 | - 文件保存位置
43 | 
44 | 例如：
45 | 
46 | ```bash
47 | java -jar oldpbft-jar-with-dependencies.jar 127.0.0.1 8080 0 C:\\Users\\XiaoHui\\Desktop\\data\\
48 | ```
49 | 
50 | 因此，你可以在本机上运行多个节点（保证端口号和序号不同即可）。
51 | 
52 | ### 在IDEA中运行的方法
53 | 
54 | 首先配置启动，允许多个main执行
55 | 
56 | ![](imgs/image-20200616113601203.png)
57 | 
58 | 然后，每次启动一个节点，更改 `i` 就可以启动不同的节点。
59 | 
60 | ```java
61 | int i = 0;
62 | String ip = "127.0.0.1";
63 | int port = 8080 + i;
64 | StartConfig.basePath = "C:\\Users\\XiaoHui\\Desktop\\data\\";
65 | int index = i;
66 | ```
67 | 
68 | # 注意点
69 | 
70 | 
71 | 
72 | 1. 程序会自动新建一个json文件，里面保存节点的ip信息，`StartConfig.basePath`代表json文件保存位置。
73 | 
74 |    ![](imgs/image-20210115214021655.png)
75 |    
76 |    
77 | 
78 | 
79 | 
80 | 2. 如果结束所有节点，然后重新启动程序，需要将`ip.json`中的内容全部删除。（比如说你启动了1节点，2节点，然后你关闭了这个程序，又想重新启动1节点2节点就必须删除）,否则会报错，如下图所示：
81 | 
82 |    ![](imgs/image-20210115214211047.png)
83 |    
84 | 3. 只有主节点能够发送消息，其他节点会发送消息失败。如何想使用非主节点发送消息，可以去修改代码。如下图所示：将红框内的代码注释即可。![](imgs/image-20210115222620783.png)
85 | 
86 | 
87 | 
88 | # 完成功能
89 | 
90 | 实际上代码完成的功能很少很少，就是完成了PBFT中的节点加入功能，然后还有消息发送PBFT认证功能，以及交易数据保存的功能**<只写了函数，需要自己去调用>**。其他的就emm没有做。本人对区块链也不是特别的了解，所以有些功能感觉实现起来的代码怪怪的。
91 | 
92 | 这个仓库代码大概率不会进行更新了，因为emmmmmm，考研去了。
93 | 
94 | 考研结束，重新更新一波。
