SpringBoot接口快速生成

• • SpringBoot接口快速生成
  • • 主要步骤
    • java目录的项目包下
    • • controller包下建立xxxController.java
      • mapper包下面创建xxxMapper.java(interface)
      • pojo包下面创建xxx.java
      • server包下面创建xxxService.java
    • resources目录下
    • • mapper目录下创建xxxMapper.xml
      • 配置application.yaml
    • pom.xml

# 选择必要的配置
# 在java目录的项目下建立mapper,server,controller,pojo包
# 在resources目录下建立mapper目录,且配置application.yaml
