 *
 * HTML filtering utility for protecting against XSS (Cross Site Scripting).
 *
 * This code is licensed LGPLv3
 *
 * This code is a Java port of the original work in PHP by Cal Hendersen.
 * http://code.iamcal.com/php/lib_filter/
 *
 * The trickiest part of the translation was handling the differences in regex handling
 * between PHP and Java.  These resources were helpful in the process:
 *
 * http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.html
 * http://us2.php.net/manual/en/reference.pcre.pattern.modifiers.php
 * http://www.regular-expressions.info/modifiers.html
 *
 * A note on naming conventions: instance variables are prefixed with a "v"; global
 * constants are in all caps.
 *
 * Sample use:
 * String input = ...
 * String clean = new HTMLFilter().filter( input );
 *
 * The class is not thread safe. Create a new instance if in doubt.
 *
 * If you find bugs or have suggestions on improvement (especially regarding
 * performance), please contact us.  The latest version of this

8.启动

在gulimall-product项目的pom文件中引入gulimall-common

 <dependency>
       <groupId>com.atguigu.gulimall</groupId>
       <artifactId>gulimall-common</artifactId>
       <version>0.0.1-SNAPSHOT</version>
  </dependency>

现在gulimall-product不报红,接着配置mybatis-plus,详情请参考mybatis-plus官网添加链接描述

8.1.在 application.yml 配置文件中添加 H2 数据库的相关配置

spring:
  datasource:
    username: root
    password: root
    url: jdbc:mysql://192.168.56.10:3306/gulimall_pms
    driver-class-name: com.mysql.jdbc.Driver


mybatis-plus:
  mapper-locations: classpath:/mapper/**/*.xml
  global-config:
    db-config:
      id-type: auto #主键自增

server:
  port: 10000
logging:
  level:
    com.atguigu.gulimall: debug

8.2.启动类上加MapperScan,扫描 Mapper 文件夹

package com.atguigu.gulimall.product;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@MapperScan("com.atguigu.gulimall.product.dao")
public class GulimallProductApplication {

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

}

8.3.测试

package com.atguigu.gulimall.product;

import com.atguigu.gulimall.product.entity.BrandEntity;
import com.atguigu.gulimall.product.service.BrandService;
import org.junit.jupiter.api.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@SpringBootTest
class GulimallProductApplicationTests {
    @Autowired
    BrandService brandService;

    @Test
    public void testBrand() {
        BrandEntity brandEntity = new BrandEntity();
//        brandEntity.setName("Iphone 13");
//        brandEntity.setDescript("苹果2021年新款");
//        brandService.save(brandEntity);

//        brandEntity.setBrandId(1L);
//        brandEntity.setSort(1);
//        brandService.updateById(brandEntity);

        BrandEntity brand = brandService.getById(1L);
        System.out.println(brand);
        System.out.println("--------------------success !-----------------------");
    }
