MyBatisPlus防全表更新与删除的实现示例

package com.example.core.config;

import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.BlockAttackInnerInterceptor;
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;

@Configuration
@MapperScan("com.example.web")
public class MybatisPlusConfig {

    /**
     * 添加拦截器
     */
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor() {
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        interceptor.addInnerInterceptor(new BlockAttackInnerInterceptor()); // 针对 update 和 delete 语句 作用: 阻止恶意的全表更新删除
        interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));// 如果配置多个插件,切记分页最后添加
        // interceptor.addInnerInterceptor(new PaginationInnerInterceptor()); 如果有多数据源可以不配具体类型 否则都建议配上具体的DbType
        return interceptor;
    }
}

    /**
     * 更新全表
     */
    @Test
    public void updateAll() {
        User user = new User();
        user.setGender(GenderEnum.MALE);

        mapper.update(user, null);
    }

    /**
     * 删除全表
     */
    @Test
    public void deleteAll() {
        mapper.delete(null);
    }

    /**
     * 更新一条数据
     */
    @Test
    public void update() {
        User user = new User();
        user.setId(7L);
        user.setGender(GenderEnum.MALE);

        mapper.updateById(user);
    }
