In Spring, @ RequestParam is used to accept url parameters of the Date type, @ requestparamdate

First introduce the joda-time package. Maven dependency:

        <dependency>            <groupId>joda-time</groupId>            <artifactId>joda-time</artifactId>            <version>2.4</version>        </dependency>

In the Controller code:

public String testMethod(@RequestParam @DateTimeFormat(pattern="yyyy-MM-dd") Date testdate){    System.out.println(testDate);}

Use pattern to specify the date format.

Test url:

? Testdate = 2014-09-04

Spring @ RequestParam

Use the following method:
@ RequestMapping ("/addHouse. do ")
Public String addHouse (
@ RequestParam (value = "companyId", required = true) int companyId,
@ RequestParam (value = "pics", required = false) CommonsMultipartFile pics,
HttpServletRequest request, HttpServletResponse response, ModelMap model ){
...
...
Model. addAttribute ("pics", pics );
Return "redirect:/addHousePic. do ";

Sample: addHousePic. do: pics null companyId can be successfully transferred.

@ Controller
• Example

Public class SoftCreateController extends SimpleBaseController {}

• Or
@ Controller ("softCreateController ")

• Description

• Or
@ Service ("softCreateServiceImpl ")

• Description
@ Service registers a bean to the spring context. bean IDs start with the class name and start with lowercase letters by default.
