The previous section briefly introduces how to obtain user locations and use longitude and latitude to represent locations. This section describes geographical encoding.
First, we need to know what is geocode
Concept:
Geographic code: it refers to the process of establishing the spatial coordinate relationship between statistical data or address
. However, most of these services do not have a Python-specific library and are inconsistent with each other's JSON structure. As a geocoder, the disobedient python God made a special geocoding tool to unify the services of these different vendors.

There is a field in the action that is of the birthday or date type. When we pass the value, it must be written as to automatically convert the type, however, in some cases, you may need to write 19990101 so that automatic type conversion is not performed by default. 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

To achieve these transformations, there is a magician in Struts 2.0 who can help you--converter. With it, you don't have to repeat this code over and over again:
Date birthday = dateformat.getinstance (dateformat.short). Parse (strdate);
OK, now let's take a look at an example.
