error: stray ‘\343’ in program [How to Solve]

Problem phenomenon:

Cause of problem:

This error is basically generated by copying the code from the web page and compiling it. Because the copied code contains Chinese spaces and characters, it can’t be distinguished by the naked eye.

Solution:

1. When the amount of code is small, it is best to re type it at the error location, then save it and recompile it.

Error prompts the location information of the error. Find the corresponding place to change.

2. It can also be used when there are many codes, or the replacement function of GEDIT can be used to replace with standard spaces, which is more labor-saving.

Find characters in error:

Under Linux, you can:

cat xxx.c -A

Chinese will be displayed as characters with red lines.

[Solved] org.thymeleaf.exceptions.TemplateInputException: Error resolving template

This problem occurs when spring boot} integrates thymeleaf

By querying other people’s blogs. I understand that there are several possible errors

1 when the method corresponding to your controller layer returns the HTML path and name, add an additional /.

For example, return “/index”. If this ‘/’ causes an error, the solution is to remove the ‘/’ in front of the return, such as return “/index”

2. Introduction package problem (I solved it this way)

[Solved] minio Failed to Upload File Error: The difference between the request time and the server‘s time is too large.

Problem Description:

Minio upload failed. The background controller reports an error. The error information is as follows:

The difference between the request time and the server's time is too large.

Cause analysis:

The system time zone is inconsistent with the hardware time zone

Solution:

Note: when uploading files, you need to adjust the time of Linux server to be consistent with that of windows!

Step 1: install NTP service

yum -y install ntp

Step 2: start the startup service

systemctl enable ntp

Step 3: start the service

systemctl start ntpq

Step 4: change the time zone

timedatectl set-timezone Asia/Shanghai

Step 5: enable NTP synchronization

timedatectl set-ntp yes

Step 6: synchronize time

ntpq -p

Finally, you can try to enter the command} on the console to check whether it is consistent with the windows system time

date
