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
spring.redis.host=
# Redis服务器连接端口
spring.redis.port=6379
# Redis服务器连接密码（默认为空）
spring.redis.password=
# 连接池最大连接数（使用负值表示没有限制）
spring.redis.jedis.pool.max-active=8
# 连接池最大阻塞等待时间（使用负值表示没有限制）
spring.redis.jedis.pool.max-wait=-1ms
# 连接池中的最大空闲连接
spring.redis.jedis.pool.max-idle=8
# 连接池中的最小空闲连接
spring.redis.jedis.pool.min-idle=0
# 连接超时时间（毫秒）
spring.redis.timeout=1000ms

mybatis.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl

#数据库
spring.datasource.type = com.alibaba.druid.pool.DruidDataSource
spring.datasource.driver-class-name = com.mysql.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/*.xml
mybatis.type-aliases-package=club.lovewangxi.dal.entity
# 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 orderId
mybatis.configuration.map-underscore-to-camel-case=true

#logging.level.root = WARN
#logging.level.org.springframework.web = DEBUG
##比如 mybatis sql日志
#logging.level.org.mybatis = INFO
#logging.level.club.lovewangxi.dal = DEBUG

2. application-dev.properties

开发环境

#开发环境
server.servlet.context-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）
spring.redis.database=1

## 日志
logging.level.* = DEBUG
#logging.pattern.console= %d - %msg%n
logging.path=D:/logs/payroll/
logging.file=D:/logs/payroll/logs.log
