Common problem 2: cnpm-Resolve "cnpm: Cannot load file C:\Users\93457\AppData\Roaming\npm\cnpm.ps1 because it is forbidden to run scripts on this system. For more information..."

The root cause of all problems is in "node_modules". Before npm install, this folder should be deleted, and then install and run.
Run npm run dev again to return to normal:
2. renren-generator
1.clone
https://gitee.com/renrenio/renren-generator.git
Then place the project under the path of "gulimall", then add the Module, and submit it to github
2. Configure application.yml in renren-generator
url: jdbc:mysql://192.168.56.10:3306/gulimall-pms?useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=Asia/Shanghai
username: root
password: root
3. Modify the configuration
renren-generator/src/main/resources/generator.properties
#代码生成器，配置信息
# 主目录
mainPath=com.bigdata
#包名
package=com.bigdata.gulimall
#模块名
moduleName=product
#作者
author=cosmoswong
#Email
[email protected]
#表前缀(类名不会包含表前缀) # 我们的pms数据库中的表的前缀都pms
# 如果写了表前缀，每一张表对于的javaBean就不会添加前缀了
tablePrefix=pms_
(The garbled Baidu IDEA here sets the properties encoding)
4. Run "renren-generator"
访问：<http://localhost:80/
Click "renren-fast", you can see that it lists all the tables of "renren-fast":
Select all the tables, then click "Generate Code", unzip the downloaded "renren.zip", take out the main folder, and place it in the main directory of the "gulimall-product" project.
The following modules are also operated in the same way.
But for "undo_log", there is a problem
Its data type is "longblob" type. After reverse engineering, the corresponding data type is unknown:
How to solve this problem?
5. Configure the project application.yml
spring:
datasource:
username: root
password: root
url: jdbc:mysql://192.168.56.10:3306/gulimall-pms?useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=Asia/Shanghai
driver-class-name: com.mysql.jdbc.Driver
# MapperScan
# sql映射文件位置
mybatis-plus:
mapper-locations: classpath:/mapper/**/*.xml
global-config:
db-config:
id-type: auto
The difference between classpath and classpath*:
classpath: only find files in your class path;
classpath*: not only include the class path, but also the jar file (class path) for searching
. The use of classpath*: when there are multiple Classpath path, and load files under multiple classpath paths (most of which will not be encountered in this case) at the same time, it plays a role, if not added , it means that only the first classpath path is loaded.
6. Add annotation @MapperScan() to the main startup class
Scan the *Mapper.java file
7. Test
@SpringBootTest
class gulimallProductApplicationTests {
@Autowired
BrandService brandService;
@Test
void contextLoads() {
BrandEntity brandEntity = new BrandEntity();
brandEntity.setDescript("哈哈1哈");
brandEntity.setName("华为");
brandService.save(brandEntity);
System.out.println("保存成功");
}
}
