spring boot 练手实战项目说明
码神之路网站所使用的博客，项目简单，需求明确，容易上手，非常适合做为练手级项目。
后端视频：bilibili
前端视频：bilibili
成品展示：blog.mszlu.com
项目：
- 提供前端工程，只需要实现后端接口即可
- 项目以单体架构入手，先快速开发，不考虑项目优化，降低开发负担
- 开发完成后，开始优化项目，提升编程思维能力
- 比如页面静态化，缓存，云存储，日志等
- docker部署上线
- 云服务器购买，域名购买，域名备案等
项目使用技术：springboot + mybatisplus+redis+mysql
工程搭建
前端的工程
npm install
npm run build
npm run dev
新建maven工程

application.properties配置
mybatis-plus.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl
使其打印到控制台
mybatis-plus.global-config.db-config.table-prefix=ms_
代表标识下前缀是ms_，这样使其省略前缀，不用再定义前缀的表名
#service
server.port=8888
spring.application.name=huing
# datasource
spring.datasource.url=jdbc:mysql://localhost:3306/blog?useUnicode=true&characterEncoding=UTF-8&serverTimeZone=GMT%2b8
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
#mybatis-plus
mybatis-plus.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl
#标明表的前缀是ms_
mybatis-plus.global-config.db-config.table-prefix=ms_
启动类和配置类
启动类：
package com.huing.blog;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* @author huing
* @create 2022-07-03 10:01
*/
@SpringBootApplication
public class BlogApp {
public static void main(String[] args) {
SpringApplication.run(BlogApp.class,args);
}
}
mybatisPlus配置类：
package com.huing.blog.config;
import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
/**
* @author huing
* @create 2022-07-03 10:02
*/
@Configuration
@MapperScan("com.huing.blog.dao.mapper")
public class MyBatisPlusConfig {
//分页插件
//@Configuration可理解为用spring的时候xml里面的<beans>标签。
// @Bean可理解为用spring的时候xml里面的<bean>标签。
@Bean
public MybatisPlusInterceptor mybatisPlusInterceptor(){
MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
interceptor.addInnerInterceptor(new PaginationInnerInterceptor());
return interceptor;
}
}
webMVC配置类：
package com.huing.blog.config;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
/**
* @author huing
* @create 2022-07-03 10:06
*/
@Configuration
public class WebMVCConfig implements WebMvcConfigurer {
@Override
public void addCorsMappings(CorsRegistry registry) {
//跨域配置，不可设置为*，不安全, 前后端分离项目，可能域名不一致
//本地测试 端口不一致 也算跨域
registry.addMapping("/**")
.allowedOrigins("http://localhost:8080");
}
}
