The method introduced in this paper is simple, fast and practical. Let's let Xiaobian take you to learn "how to deal with the problem that some attributes of @RequestBody have not been successfully converted"!

@RequestBody partial attributes were not converted successfully

Found in the project when writing the API interface for adding User

I set the User parameter to @ResquestBody, but when testing, I found that even if all the attributes are passed in, only some attributes in the received User instance are converted, and other attributes are not converted successfully.

Later, after investigation, it was found that @ResquestBody only converted attributes with getters. I added getters to all attributes, and then I could convert them correctly!

In addition, I found that if it is boolean attribute, you can add isXX() method, but also

@RequestBody Some attribute values are not available

@RequestBody The attribute name in the entity class received by @RequestBody cannot be converted from JSON to instance class attribute normally if the first letter is lowercase and the second letter is capitalized.

solutions

Option 1:

Change the name, change the second capital to lowercase on the line (in actual development, change the name so that the name does not conform to the hump naming method is not appropriate)

Option 2:

Add @JsonProperty annotation, specify the name of a method when JSON conversion, the above entity class will be modified to

@JsonProperty(value = "pCode") private String pCode; At this point, I believe that everyone has a deeper understanding of "how to deal with the problem that some attributes of @RequestBody have not been successfully converted".
