What should I do if a third-party interface is called in Spring Boot project, and the field name case and getter method are inconsistent, resulting in data transmission failure?

When Spring Boot project calls a third-party interface, the field case does not match the getter method and the solution to the data transmission failure

This article analyzes and answers the data transmission problems encountered when calling third-party interfaces in a Spring Boot project. The developer created the entity class field as measID , but the data transfer failed. After modifying the field name meas_id , the data arrives at the third-party interface and is recorded in the log, but the error "Array measID is not defined".

The root cause of the problem is that third-party interfaces may have specific requirements for the case and naming specifications of field names (camel or underscore). After modifying the field name to meas_id , although the data transmission is successful, the "Undefined array measID" error indicates that the third-party interface still tries to access the getter method corresponding to measID ( getMeasID() ). Since the developer only modified the field name and did not modify the getter method name synchronously, the getter method name is inconsistent with the field name, and the third-party interface cannot obtain the field value correctly.

Solution: Synchronously modify the field name and getter method name. If the field is named meas_id , the getter method must be named getMeasId() (following the Java Bean specification). Ensure that the field name and getter method name are exactly the same, thereby solving the problem of data transmission failure. The data can be seen in the log, just because there is no problem with the data transmission itself, but because the getter method does not match, the interface cannot parse and use the data correctly.
