springboot使用心得

1、springboot的pom.xml配置如下：

 

<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <relativePath/> <!-- lookup parent from repository -->

2、springboot的application.yml配置如下：

 

server:

  port: 8080

spring:

  datasource:

    url: jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8

    username: root

    password: 123456

    type: com.alibaba.druid.pool.DruidDataSource

    driver-class-name: com.mysql.jdbc.Driver

  freemarker:

    request-context-attribute: req  #req访问request

    suffix: .ftl  #后缀名

    template-loader-path: classpath:/templates/ #模板加载路径 按需配置

    charset: UTF-8 #编码格式

    settings:

      number_format: '0.##'   #数字格式化，两位小数

mybatis:

  mapper-locations: classpath:mapping/*.xml  #注意：一定要对应mapper映射xml文件的所在路径

  type-aliases-package: com.test.model  #注意：对应实体类的路径
