基于SpringBoot搭建RestAPI接⼝服务（基于IDEA）1. 项⽬构建
1. IDEA内置了SpringBoot启动
2. 填写项⽬相关信息
3. 根据项⽬需要选择所需依赖，这⾥搭建RestAPI服务
2. 项⽬配置参考
项⽬配置可以配置多个application，开发，测试，⽣产，通过配置spring.profiles.active=dev启⽤不同的配置⽂件1. application.properties
springBoot配置⽂件 （可以按照项⽬需求，把各个环境不变的配置配置在这⾥）
# 配置启动环境加载不同的配置⽂件
spring.profiles.active=dev
# Redis服务器地址
# Redis服务器连接端⼝
# Redis服务器连接密码（默认为空）
# 连接池最⼤连接数（使⽤负值表⽰没有限制）
# 连接池最⼤阻塞等待时间（使⽤负值表⽰没有限制）
# 连接池中的最⼤空闲连接
# 连接池中的最⼩空闲连接
# 连接超时时间（毫秒）
#数据库
pe = com.alibaba.druid.pool.DruidDataSource spring.datasource.driver-class-name = sql.jdbc.Driver
spring.datasource.initialSize=5
spring.datasource.minIdle=5
spring.datasource.maxActive=20
spring.datasource.maxWait=60000
# 注意注意
mybatis.mapper-locations= classpath:club/lovewangxi/dal/dao/*.pe-aliases-package=club.ity
# 驼峰命名规范如：数据库字段是  order_id 那么实体字段就要写成 figuration.map-underscore-to-camel-case=true
# = WARN
#springframework.web = DEBUG
##⽐如 mybatis sql⽇志
#batis = INFO
#logging.level.club.lovewangxi.dal = DEBUG
2. application-dev.properties
开发环境
#开发环境
t-path=/payroll
server.port=8081
#JDBC 连接
spring.datasource.url=
spring.datasource.username=
spring.datasource.password=
# Redis数据库索引（默认为0）
## ⽇志
logging.level.* = DEBUG
#sole= %d - %msg%n
logging.path=D:/logs/payroll/
logging.file=D:/logs/payroll/logs.log
