Struts-json-plugin serialization of a configuration object in result

Note: Use the object name when you use the Strtus-json-plugin serialization object property to configure the Includeproperties property under the result label. * or specify a property name in such a way that the object property name cannot be written.

Problem:

There are two properties in action: String result and users of list type. The two properties are serialized into a JSON string by Struts-json-plugin and returned to the client, configured as follows:

  <Actionname= ""class= ""> 　　　 <resultname= "Success"type= "JSON">         　　 <paramname= "Includeproperties">result, users</param> 　　    </result> 　     </Action>

With the above configuration, return to the client page can only see the value of result, the users display as {}, empty.

To modify the configuration:

   <Actionname= ""class= ""> 　　　 <resultname= "Success"type= "JSON">         　　 <paramname= "Includeproperties">result, users\[\d+\]</param> 　　    </result> 　     </Action>

The client page can get the value of result normally, but the users value is displayed as {{},{} ...}. Obviously, the value is not obtained correctly.

To modify the configuration:

   <Actionname= ""class= ""> 　　　 <resultname= "Success"type= "JSON">         　　 <paramname= "Includeproperties">result, users\[\d+\].*</param> 　　    </result> 　     </Action>

The value of result and users can be obtained normally.

You can also serialize only certain properties in the user object, such as serializing name only:

　　

Users\[\d+\].name
