This article introduces you how to customize parameter binding in SpringBoot, the content is very detailed, interested friends can refer to, hope to be helpful to you.

1. Custom parameter converter

The custom parameter converter implements the Converter interface, as follows:

Public class DateConverter implements Converter {private SimpleDateFormat simpleDateFormat = new SimpleDateFormat ("yyyy-MM-dd"); @ Override public Date convert (String s) {if (".equals (s) | | s = = null) {return null;} try {return simpleDateFormat.parse (s);} catch (ParseException e) {e.printStackTrace ();} return null;}}

The convert method takes a string parameter, which is the date string from the front end, which meets the yyyy-MM-dd format, and then converts the string to a Date object through SimpleDateFormat and returns it.

two。 Configuration converter

Custom WebMvcConfig inherits WebMvcConfigurerAdapter and is configured in the addFormatters method:

Configurationpublic class WebMvcConfig extends WebMvcConfigurerAdapter {@ Override public void addFormatters (FormatterRegistry registry) {registry.addConverter (new DateConverter ());}}

OK, after the above two steps, we can receive a string date from the front end on the server side and convert it to a Date object in Java. The front end date control is as follows:

The server APIs are as follows:

@ RequestMapping (value = "/ emp", method = RequestMethod.POST) public RespBean addEmp (Employee employee) {if (empService.addEmp (employee) = = 1) {return new RespBean ("success", "add successful!");} return new RespBean ("error", "add failed!") } on how to customize the parameter binding in SpringBoot to share here, I hope the above content can be of some help to you, can learn more knowledge.
