一：整合mybatis-plus

1.导入依赖

<dependency>
     <groupId>com.baomidou</groupId>
     <artifactId>mybatis-plus-boot-starter</artifactId>
     <version>3.2.0</version>
</dependency>

2.配置

1）配置数据源
导入数据库驱动
在common的pom文件中

<!--导入mysql驱动-->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>8.0.17</version>
        </dependency>

1.删除comon中xss包下的XssFilter和XssHttpServletRequestWrapper文件
2.从renren-fast复制RRException到conmon项目utils路径下
2）配置驱动
在gulimail-product的resources的目录下创建application.yml文件
3）配置mybatis-plus
在gulimail-product启动类添加注解

@MapperScan("com.sysg.gulimail.product.dao")

告诉mybatis-plus，sql文件的映射位置

#数据源
spring:
  datasource:
    username: root
    password: 123456
    url: jdbc:mysql://127.0.0.1:3306/gulimail_pms
    driver-class-name: com.mysql.jdbc.Driver

#mybatis-plus映射位置
#classpath*，表示扫描本微服务和其他微服务
mybatis-plus:
  mapper-locations: classpath*:/mapper/**/*.xml
#设置id主键自增
  global-config:
    db-config:
      id-type: auto

4）测试是否配置成功
在gulimail-product的测试类中进行测试

package com.sysg.gulimail.product;

import com.sysg.gulimail.product.entity.BrandEntity;
import com.sysg.gulimail.product.service.BrandService;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
class GulimailProductApplicationTests {
    @Autowired
    private BrandService brandService;
    @Test
    void contextLoads() {
        BrandEntity brandEntity = new BrandEntity();
        brandEntity.setName("华为");
        brandService.save(brandEntity);
        System.out.println("保存成功。。。");
    }

}

测试保存

测试更新

package com.sysg.gulimail.product;

import com.sysg.gulimail.product.entity.BrandEntity;
import com.sysg.gulimail.product.service.BrandService;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
class GulimailProductApplicationTests {
    @Autowired
    private BrandService brandService;
    @Test
    void contextLoads() {
        BrandEntity brandEntity = new BrandEntity();
        /*brandEntity.setName("华为");
        brandService.save(brandEntity);
        System.out.println("保存成功。。。");*/
        brandEntity.setBrandId(1L);
        brandEntity.setDescript("小米");
        brandService.updateById(brandEntity);
    }

}
