* 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.
*

7.6.SQL过滤SQLFilter
package com.atguiigu.common.xss;
import com.atguiigu.common.exception.RRException;
import org.apache.commons.lang.StringUtils;
/**
* SQL过滤
* @author Mark [email protected]
*/
public class SQLFilter {
/**
* SQL注入过滤
* @param str 待验证的字符串
*/
public static String sqlInject(String str){
if(StringUtils.isBlank(str)){
return null;
}
//去掉'|"|;|\字符
str = StringUtils.replace(str, "'", "");
str = StringUtils.replace(str, "\"", "");
str = StringUtils.replace(str, ";", "");
str = StringUtils.replace(str, "\\", "");
//转换成小写
str = str.toLowerCase();
//非法字符
String[] keywords = {"master", "truncate", "insert", "select", "delete", "update", "declare", "alter", "drop"};
//判断是否包含非法字符
for(String keyword : keywords){
if(str.indexOf(keyword) != -1){
throw new RRException("包含非法字符");
}
}
return str;
}
}
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 ！-----------------------");
}
}
