Springboot upgrade to 2.x where changes are needed

Due to the need to follow up the pace of technological development, The original Project Springboot 2.0 upgrade, but upgrade is not to say change the version is done, springboot2.0 change more, detailed changes can Baidu, the following for upgrade Springboot encountered problems record, hope to upgrade students useful:

1.Redis

To add a POM configuration:

        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId> Spring-boot-starter-data-redis</artifactid>        </dependency>
