Cascading:
If a new field is added to the database, then:
1 The select/insert/update in dao.xml needs to be modified
2 The corresponding class needs to be added, and the set/get method is specified
3jsp/js, setting/getting also needs to be added
4controller
If it is a class parameter, it can be ignored,
If not, then also need to consider
That is, if a modification is made, it is necessary to take into account all the possible occurrences/possible uses, and modify them, and omissions should be avoided.

Example: (1) Front-end-(2)a->(3) Back-end-(4)b->(5)Database
Step 1: Determine where the problem is
[
For example, if you locate an error in step 2, you can ignore the non-error item 3/4/5
]
Step 2: Identify the specific error link
[
For example: when getting form data, an element gets an error
When getting date data, no formatting is performed
]
Step 3: Try to solve: After locating the error, [non-system/non-universal/], if the impact on the project is not correct or has no impact, you can let go of your thinking and dare to try to modify
[
For example: display as input, but if you find something wrong, you can try to replace it with other labels
Suggestion: Before modifying, you can think about it first, then in Baidu Baidu, and finally try it out
]
Step 4: Ask for help
[
4.1 Ask for advice from experienced people [personal experience: I work hard on my own, sometimes it is better to be guided by the elders and have a clearer mind]
4.2 In non-emergency situations, it can be done through groups/network platforms, etc.
]
Suggestion: If something goes wrong, keep your mind clear
