SpringBoot创建及配置（一）

创建流程

1. 创建Maven项目，设置Maven架构类型为maven-archetype-quickstart：

2. 创建项目后，修改其pom.xml文件，如下：

<project xmlns="http://maven.apache.org/POM/4.0.0"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

                     </plugin> 
		</plugins>
	</build>
	
</project>

3. 在項目的/resources下配置application.properties（主要包括数据库jdbc，热部署，MyBatis映射文件地夹设置等），如下：

######  data config start ###### 
spring.jpa.properties.hibernate.hbm2ddl.auto=update
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
spring.jpa.show-sql= true
spring.datasource.hikari.connectionInitSql=SET NAMES utf8mb4 COLLATE utf8mb4_unicode_ci;

######   DB config end ###### 
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/lost_back?useSSL=false
spring.datasource.username=root
spring.datasource.password=19970121
spring.datasource.driver-class-name=com.mysql.jdbc.Driver


######   Mapper config
mybatis.mapper-locations=classpath:mapper/*.xml

# Page default prefix directory
server.servlet.jsp.init-parameters.development=true
spring.mvc.view.prefix=/WEB-INF/jsp/
# Response page default suffix
spring.mvc.view.suffix=.jsp


# Configuring hot deployment
spring.devtools.restart.enabled: true
# Set the restart directory   do not restart the folder WEB-INF/**
spring.devtools.restart.exclude: WEB-INF/**
spring.thymeleaf.cache=false
