In this way, you can write a custom type converter to achieve conversion. Struts2 has two types of converters: Partial: it applies to an action conversion type. First, you need to customi

Struts2 registers a local converter and a local Converter To implement a custom converter, You need to inherit the defatypetypeconverter class or the StrutsTypeConverter class from the objects to be converted, and obtain the entry of a type converter to implement the developer's own type
