SSM项目转Springboot项目

SSM项目转Springboot项目

由于几年前写的一个ssm项目想转成springboot项目，所以今天倒腾了一下。
最近有人需要毕业设计转换一下，所以我有时间的话可以有偿帮忙转换，需要的私信我或＋v：Arousala_

首先创建一个新的springboot的工程，然后复制一下相关的依赖

复制webapp在main和resources目录中，可以删除webapp中的web.xml,配置自行添加到启动类中

在启动类中写好注解

package com.dhnsoft;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@MapperScan("com.dhnsoft.mapper")
@ServletComponentScan(basePackages = "com.dhnsoft.code")
public class OnlineMallApplication {

    public static void main(String[] args) {
        SpringApplication.run(OnlineMallApplication.class, args);
    }
}

还有一个错误如下

加上文件前缀即可
