spring-boot - Spring Boot部署：在类路径资源中创建名称为'entityManagerFactory'的bean时出错(Spring boot deploy: Error creating bean with name 'entityManagerFactory' defined in class path resource)

I try deploy my spring boot web application to AWS Elastic Beanstalk.

(我尝试将Spring Boot Web应用程序部署到AWS Elastic Beanstalk。)

I saw full logs and there is stack trace like below, but when I run mvn clean package in Intellij idea terminal I get the same errors like below.

(我看到了完整的日志，并且有如下所示的堆栈跟踪，但是当我在Intellij idea终端中运行mvn clean package时，也会遇到类似的错误。)

I was using 'mvn clean package -DskipTests' to now and command wasn't finish broke result.

(我现在使用的是“ mvn clean package -DskipTests” ，命令未完成中断结果。)

There was no errors in terminal, but when I use this command without -DskipTests stack trace error is like below:

(终端中没有错误，但是当我不带-DskipTests使用此命令时，堆栈跟踪错误如下所示：)

Can you tell me why I get this error ?

(您能告诉我为什么会出现此错误吗？)

How resolve this problem ?

(如何解决这个问题？)

On The other band, what can cause this error with entitymanagerfactory ?

(在另一个频段上，什么会导致Entitymanagerfactory出现此错误？)

I checked conflicts in pom.xml and There was conflicts between httpclient nad httpcore, I removed this dependencies but error still occur.

(我检查了pom.xml中的冲突，并且httpclient nad httpcore之间存在冲突，我删除了此依赖项，但仍然发生错误。)

Any idea?

(任何的想法？)

I searched in other stackoverflow topics and I didn't find any solution.

(我搜索了其他stackoverflow主题，但没有找到任何解决方案。)

Nothing worked.

(没事。)

I know from other post in stackoverflow that test class don't want to compile.

(我从stackoverflow的其他文章中知道测试类不想编译。)

I don't know why.

(我不知道为什么)

Here is my pom.xml file:

This error is related to your JPA means your database connection is creating some trouble.

(此错误与您的JPA有关，意味着您的数据库连接正在引起一些麻烦。)

Please check the configuration for your DB mentioned in properties file and also, check your entities as well if anything is wrong with them.

(请检查属性文件中提到的DB的配置，还请检查您的实体是否存在问题。)

Also, share application.properties file here as well for better understanding.

(另外，也可以在此处共享application.properties文件，以更好地理解。)
