SpringMVC Web项目升级为Springboot项目(一)
一、项目改为Springboot项目
1.将pom中所有spring相关依赖删除,添加spring-boot-starter及spring-boot-starter-web(项目中可能有其他spring依赖,单独添加即可)
2.将pom中mybatis相关依赖删除,添加mybatis-spring-boot-starter
3.添加application.properties文件,在其中配置数据库相关配置项
spring.datasource.url=jdbc:mysql://202.16.199.1:3306/Book?useSSL=true&verifyServerCertificate=false&characterEncoding=UTF-8 spring.datasource.username=root spring.datasource.password=123123 spring.datasource.driver-class-name=com.mysql.jdbc.Driver spring.datasource.max-idle=10 spring.datasource.max-wait=10000 spring.datasource.min-idle=5 spring.datasource.initial-size=5
4.添加Application类
package com.gauge.childheart; import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.web.servlet.support.SpringBootServletInitializer; import org.springframework.context.annotation.ComponentScan; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @SpringBootApplication @RestController @ComponentScan(basePackages = "com.gauge.childheart.*") @MapperScan(value = "com.gauge.childheart.mapper") public class Application extends SpringBootServletInitializer { public static void main(String[] args) { SpringApplication.run(Application.class, args); } @RequestMapping("/") public String hello() { return "hello"; } }
5.报错:Consider defining a bean of type xxxxMapper in your configuration
在Application类添加注解@MapperScan(value = "com.xxxx.mapper")
至此,项目可以正常启动
