Solution:
Put the druid.properties file in the SRC directory
Change to absolute path:
Properties pro =new Properties();
// InputStream is= JDBCUtils.class.getClassLoader().getResourceAsStream("src/main/druid.properties");
// pro.load(is);
pro.load(new FileReader("src/druid.properties"));
ds= DruidDataSourceFactory.createDataSource(pro);Error 1：

Write a description document for the component library, but an error is reported when packaging and deployment: the document is not defined. You can only find out the reason after checking the data, because vuepress is rendered through the node.js server when packaging, and an error is reported because there is no document object in node.js. The final solution is as follows:. Vuepress/enhanceapp.js folder
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
//The way it was introduced before - will cause an error to be reported
// import CommonUI from 'vue-common-ui'
import 'vue-common-ui/lib/vue-common-ui.css'
export default async ({ Vue }) => {
if (typeof process === 'undefined') {
Vue.use(ElementUI)
// Solve the problem of introducing your own components with the error document not found
Vue.mixin({
mounted() {
import('vue-common-ui').then(function(m) {
Vue.use(m.default)
})
}
})
}
}
After modifying the introduction method of Vue common UI components, the online address of the component library is normally packaged

Solution:
Method 1: A simple and straightforward solution
Add arch -x86_64 in front of the pod command
e.g. arch -x86_64 pod update
Method 2: reinstall cocoaPods
Answering my own question. I fixed the ffi issue by uninstalling my faulty Ruby version and CocoaPods, then I used the -x86_64 arch to reinstall ffi and CocoaPods.
These are the steps I did to get back to a working state (and to apply the M1 workarounds for ffi):
Uninstall Ruby with: brew uninstall ruby –force
Uninstall CocoaPods. At first, try to list all CocoaPods versions / components with gem list –local | grep cocoapods. Then uninstall them one by one, in my case:
sudo gem uninstall cocoapods
sudo gem uninstall cocoapods-core
sudo gem uninstall cocoapods-downloader
etc.
As a next step I was able to reinstall ffi and then CocoaPods with:
sudo arch -x86_64 gem install ffi
sudo arch -x86_64 gem install cocoapods
Once done, I could run pod install as expected. Note that I had the Terminal open all the time in standard mode – no Rosetta required

Analyze the cause of the error
Combined with their own understanding and the analysis of others on the Internet, the positioning is as follows:
Solution
1 from the perspective of reason, the simplest solution is to directly modify the MySQL configuration file my.ini and directly set the “wait_timeout” to a larger value, which can be set to about 24 days. However, this does not eliminate such abnormalities from the root, but delays the number and time of abnormal “explosion”
2 modify the Druid connection pool to reduce the connection cycle in the connection pool and recycle invalid connections as much as possible
make the maximum connection lifetime less than the “wait_timeout” time of MySQL.
# Configure the minimum time, in milliseconds, for a connection to survive in the pool
spring.datasource.minEvictableIdleTimeMillis=30000
spring.datasource.maxEvictableIdleTimeMillis=180000
UnorderedObjectListWarning: Pagination may yield inconsistent results with an unordered object_list: <class ‘myapp.models.Power’> QuerySet.
paginator = self.django_paginator_class(queryset, page_size)
The reason is that you are not sorting.
Solution.
(a) add ordering to the design of the model
class test(models.Model):
...
class Meta:
...
ordering=["xx"](b) Add order_by to the query set for sorting

Solution:
This problem actually has nothing to do with the version, but with the screen allocation rate. The layout xml defines the layout_height referencing the constant defined in the values, but the definition is only defined in the directory of the specific resolution. So the solution Define the referenced value in the values directory
