The sale object passed from the background is sale = null
${sale.warrantyPeriod}
You will be prompted that warrantyperiod cannot be found. Change it to the following:
th:value="${sale?.warrantyPeriod}"
If the object is empty, the output is empty; if the object exists, the output property value.
The error is shown in the figure 
The reason for this error is that there are two bridges when the log information is generated, and the conflict results in error.
The solution is as follows:
Find the structure diagram in the POM file, and press and hold the Cril key to enlarge the diagram
Find the dependency as shown in the figure below, because there are two bridge conflicts, we only need to eliminate one
As shown in the figure below, right-click the logback classic we found and left-click exclude
At this point, our modification is good. Return to our POM file and update our modification, as shown in the following figure: 
At this point, we can run our project again and find that our mistakes are gone, as shown in the figure below.
Why does asset database transaction committed tweet appear in unity
Assertion failed on expression: ‘m_ ErrorCode == MDB_ MAP_ RESIZED || ! HasAbortingErrors()’
Solution:
save the file, re open the unity or activate the license, you can get the solution
cause: error caused by resource loss, or license expiration.

... 5 common frames omittedBecause it’s a new project, Mongo library belongs to other projects. This is just a test application. So the first doubt is that the project version driver is not compatible with mongodb library. After replacing other versions of mongodb library, it is OK.
Detailed explanation
View the
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-mongodb</artifactId>
<version>2.1.3.RELEASE</version>
</dependency>Because of spring Mongodb driver is also the official driver of encapsulated mongodb. When you enter the spring data mongodb project, you can see that the official version of mongodb driver is 3.8.2
Then go to the official website of mongodb to see that version 3.8 supports version 4.0 database at most. I started testing with the 4.2 library (Official website https://docs.mongodb.com/drivers/java/)
So that’s it.

This document records the process and steps of the initial report generation with allure.
Install allure first, download and configure the environment
reference documents:
https://www.cnblogs.com/wsy1103/p/10530397.html
After installation, the following steps begin:
Step 1: generate report data with assure. The generated report data includes two files: one JSON file and one TXT file.
Switch to D: Python/Test & gt; The following is implemented:
hrun test_post_api.json --alluredir=report
Step 2: create the report data generated just now with assure, generate the report2 folder, – O means to specify the folder to generate the report, – C means to clean up the previous report directory before generating the report.
allure generate D:\Python\test\report -o D:\Python\test\report2 -c
Then open the assure report using the default browser to view it.
allure open D:\Python\test\report2
end. The effect of successful generation:

https://ask.csdn.net/questions/3017114
Add some code to runner. Py’s test_ Start method, and import colorama, Sys at the beginning of the file
2. If the Chinese encoding in the return body fails, please refer to the document for solution:

Add some code to the log of client. Py_ In the print method, the default ASCII encoding is used for Chinese when json.dumps is serialized. To output real Chinese, you need to specify ensure_ ascii=False
[allure grammar]
$Hrun — alluredir allure results — clean alluredir # when the use case format is py file, you can replace “Hrun” with “pytest”, which has the same effect
– alluredir: generate the original data of allure report
allure results: save location of the original data
– clean alluredir: clear the historical data of allure results
$assure generate assure results – O assure report
– O specify the folder to generate the report
– C clean up the previous report directory before generating the report
Assure open assure report: start the default browser to open the assure test report

Problem explanation: This is the Linux folder that needs to be uploaded has insufficient permissions, so what should we do?
1. The first method: select the Linux folder to upload, right-click – change permissions – check all; You can upload it again. Here is the software file, as shown in the following figure:
At that time, I couldn’t check this method. The reason I thought of was that I didn’t have permission to change the permission of this folder, so I tried to find a second method on the Internet
The second method: modify the folder permission with command: Chmod 777 software, the folder that software needs to give permission to
