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
