3. Project problems and solutions
3.1. Cross-domain issues
Access protocol : http https
IP address (domain name) : oa.atguigu.com oa.baidu.com
Port number : 8800 9528
Various solutions:
(1) Add annotations on the controller class
(2) Configure on the front end
3.2, mapper scanning problem
//第一种方式 ：创建配置类，使用@MapperScan注解
@Configuration
@MapperScan(basePackages = {
"com.atguigu.auth.mapper","com.atguigu.process.mapper","com.atguigu.wechat.mapper"})
public class MybatisPlusConfig {
}
//第二种方式：在mapper的接口上面添加注解 @Mapper
@Mapper
public interface SysMenuMapper extends BaseMapper<SysMenu> {
}
3.3, xml file loading problem
By default, Maven will only load java-type files under the src-main-java directory, and other types of files will not be loaded
The first solution: put the xml file in the resources directory
The second solution: configure in pom.xml and project configuration files
3.4. Process definition deployment zip file
zip file specification (required)
(1) The name of the zip file is consistent with the process key
For example: file name qingjia.zip
(2) Package the xml file in the zip file, and the xml file is named .bpmn20.xml
For example: jiaban.bpmn20.xml
3.5. Intranet penetration problem
The interface and page are on the local localhost. If the official account cannot directly access the local path, it needs to use intranet penetration
There are two purposes:
The first one: the official account page penetrates through the intranet to the local page 9090
The second one: the interface in the official account penetrates through the intranet to the local interface 8800
3.6. Other issues
