前言

现在开发的项目多为mavne管理。熟悉idea通过maven打包流程及常见问题解决。

一、打包流程

1.1idea通过maven打包项目spring-boot项目

参看链接：

1.2配置文件

1.3本地通过java -jar命令启动

1.3.1 java命令执行jar包带环境变量

java -jar reins-monitor-backend-1.0.jar --jasypt.encryptor.password=asd
或
java -Djasypt.encryptor.password=asd -jar reins-monitor-backend-1.0.jar

1.3.2 spring-boot项目的jar文件读取配置文件的方式

二、常见问题

2.1 报错一

SpringBoot启动时报org.springframework.context.annotation.ConflictingBeanDefinitionException
解决方法参看链接： https://blog.csdn.net/u013360850/article/details/77622629/

这是因为在应用中使用到了多个该类的对象，而该类的对象通过注解的方式注入到应用中，在注入的过程中因为对象的名称重复导致了该异常 
通过指定注入对象的名称可以解决这个问题。

我报这个错的原因是因为在打包前，没有编译，还是编译有误。。。导致生成一个重复的class文件，重新编译后，打包，问题解决。

原因：jar包存放目录含有中文。
