Take a look at the
source code of FormTag below
/**
* Set the name of the form attribute in the
model.
* <p>May be a runtime expression.
*/
public void
setModelAttribute(String modelAttribute) {
this.modelAttribute = modelAttribute;
}
/**
* Get the name of the form attribute in the
model.
*/
protected String
getModelAttribute() {
return this.modelAttribute;
}
/**
* Set the name of the form attribute in the
model.
* <p>May be a runtime expression.
* @see #setModelAttribute
*/
public void
setCommandName(String commandName) {
this.modelAttribute = commandName;
}
/**
* Get the name of the form attribute in the
model.
* @see #getModelAttribute
*/
protected String
getCommandName() {
return this.modelAttribute;
}
The code from form
tag shows that they are both referring to the same field/property.
