1. problem ： Hump format parameters are passed to the back end ,@RequestBody The entity object parameter marked by the annotation does not receive the corresponding data

The front end passes the reference ：

Execution results ：

Request parameter entity ：

import lombok.Data;

/** *  Request parameters  * @author qzz */
@Data
public class DailyInspectTsznoRequestJson {
    
    private String belongedTo;
    private String recordNumber;
    private String checkFormNumber;
    private String tzsno;
    private String entCode;
}

2. resolvent ：

Method 1 ： Modify the format of front-end parameter transfer , Hump format is converted to underline lowercase format

Modify the front-end request parameters to Underline lowercase format ：

The back-end receiving parameters remain unchanged .
Restart project , The implementation effect is as follows ：

Find out , Problem solved .

Method 2 ： Add @JsonProperty("") annotation , Fill in your own attribute name , That's all right. ( Recommended )

package com.hwariot.device.report.dto.json.request.openapi;

import com.fasterxml.jackson.annotation.JsonProperty;
import lombok.Data;

/** *  Request parameters  * *  Front end delivery belongedTo Wait until the parameters reach the back end ,belongedTo And other parameters are valuable , But when the backend gets it , It's not worth it  *  terms of settlement ： *  Add  @JsonProperty("") annotation , Fill in your own attribute name , That's all right.  * @author qzz */
@Data
public class DailyInspectTsznoRequestJson {
    

    
    @JsonProperty("belongedTo")
    private String belongedTo;
    
    @JsonProperty("recordNumber")
    private String recordNumber;
  
    @JsonProperty("checkFormNumber")
    private String checkFormNumber;
    
    @JsonProperty("tzsno")
    private String tzsno;
    
    @JsonProperty("entCode")
    private String entCode;
}

The front-end parameters are saved and the hump format remains unchanged , Modify backend only .

And then restart the project , Re request , The implementation effect is as follows ：

It is found that the data has been received , Problem solved .

Be careful ： The second method is recommended .
