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

<?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"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.6.6</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.dhnsoft</groupId><artifactId>demo</artifactId><version>0.0.1-SNAPSHOT</version><name>OnlineMall</name><description>Demo project for Spring Boot</description><properties><java.version>1.8</java.version></properties><dependencies><!-- https://mvnrepository.com/artifact/org.apache.logging.log4j/log4j-core --><dependency><groupId>org.apache.logging.log4j</groupId><artifactId>log4j-core</artifactId><version>2.17.1</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>2.0.6</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-tx</artifactId><version>5.3.8</version></dependency><dependency><groupId>javax.servlet.jsp.jstl</groupId><artifactId>jstl-api</artifactId><version>1.2</version><exclusions><exclusion><groupId>javax.servlet</groupId><artifactId>servlet-api</artifactId></exclusion><exclusion><groupId>javax.servlet.jsp</groupId><artifactId>jsp-api</artifactId></exclusion></exclusions></dependency><!-- servlet依赖 --><dependency><groupId>javax.servlet</groupId><artifactId>javax.servlet-api</artifactId></dependency><dependency><groupId>javax.servlet</groupId><artifactId>jstl</artifactId></dependency><!-- tomcat的支持--><dependency><groupId>org.apache.tomcat.embed</groupId><artifactId>tomcat-embed-jasper</artifactId></dependency></dependencies><build><resources><!--这个可以使springMVC来重定向到指定的目录--><resource><!--指定目录--><directory>src/main/java</directory><!--包含在目录下的.properties,.xml文件都会扫描到--><includes><include>**/*.xml</include></includes></resource></resources><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin><!-- 打jar需要的插件--><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-jar-plugin</artifactId></plugin></plugins></build></project>

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
