原因分析：
切换项目环境时maven依赖更改为其他（生产）环境，再次切换为本地测试环境，本地测试环境相关的maven依赖没有注入到本地maven仓库，无法查询并使用
解决方案：
这个问题的解决方法，maven项目重新clean，install，package
clean 清理
清除编译产生的target文件夹内容
complie 编译
该命令可以对src/main/java目录的下的代码进行编译
package 打包
mvn package，打包项目
- 如果是JavaSe的项目,打包成jar包
- 如果是JavaWeb的项目,打包成war包
当我们使用package来打包项目的时候，就会在我们的项目中生成一个target文件夹，web项目比如mvc项目就会在该文件夹下生成一个war包，放在服务器中的tomcat/webapps目录里运行。
Java项目的话就会在该文件夹下生成一个jar包，放在服务器中指定目录下使用“java -jar jar包名” 命令运行。
一般服务器部署服务都是使用package方式进行打包项目
install 切换maven环境
重新注入maven依赖
使用install方式就是将项目转换成为maven依赖存放在本地maven仓库中。就比如我的spring boot项目使用install后存在我本地maven仓库中路径是：E:MavenRepository_IDEAorgspringframeworkboot项目名
一般是多个项目中，例如a项目中使用了b项目的一些方法需要添加b项目作为依赖，此时就需要将b项目使用install方式打包到本地maven仓库中，以此来给a项目依赖导入调用。
把项目打包之后安装到本地仓库，其实执行install之前先执行了打包，然后对项目进行安装到本地仓库
主要是切换生产环境时进行使用
例如：本地开发环境测试代码完成，将本地代码切换环境，打包成生产环境，生成可运行的生产环境jar包，部署并运行在生产，但是当同一套代码切换回本地开发环境时，环境转变，maven依赖还是开发环境时的依赖，无法直接应用到当前本地开发环境，需要将生产环境项目利用install转变为本地maven仓库中
