1、除錯好對應加解密的java檔案

2、配置maven打依賴包外掛：修改pom檔案的"<plugins>"節點下增加配置（https://blog.csdn.net/smd2575624555/article/details/81453887）

終端執行命令：mvn assembly:assembly

3、打jar包

4、檢視打好的jar包：打成的jar包是兩個一個是有依賴的一個是無依賴的可看自己的需求而定

5、遇到問題解決方案

問題：org.apache.commons.lang3不存在：

解決方案： 在pom.xml檔案中新增：

</dependency>
<dependency>
  <groupId>org.apache.commons</groupId>
  <artifactId>commons-lang3</artifactId>
  <version>3.4</version>
</dependency>

問題：org.apache.commons.codec.digest.DigestUtils不存在：

解決方案： 在pom.xml檔案中新增：

<dependency>
  <groupId>commons-codec</groupId>
  <artifactId>commons-codec</artifactId>
  <version>1.11</version>
</dependency>
