The importance of the get and set methods in struts2.

In struts2, The get and set methods are used for data transmission between the client and the server.

 

When you need to use page-based values in the business logic, you only need to ensure the Set Method of the attribute in the action and the name attribute value in the page <s: textfield name = ""/> is the same. (Remove set, and change the method name to a smaller value)

 

When you need to use the return value in the business logic to display the page, you only need to ensure that the value <s: property value = ""/> of the page tag is the same as the get method of the attribute in the action. (Same as above)
