Parsing of Springmvc method parameter customization

1, realize Handlermethodargumentresolver interface;

2. Add configuration to configuration file <mvc:argument-resolvers>
<bean class= "" ></bean>
</mvc:argument-resolvers>

Class file is the class defined in the first step

3. Define annotations to only parse the controller's method parameters with that annotation

The custom method parameter resolution realizes the unification of the front and back end data, for example, the form data is defined as a bean, and the front-end data is directly transmitted to the backend by defining the parameter resolution class.
