类型转换器(InitBinder 初始化绑定器)

单日期格式

导入jar包

 

创建FirstController.java

 @Controller
	public class FirstController {
    	 /**
    	  * @param binder
    	  */
    	 
    	@InitBinder
    	public void initBinder(WebDataBinder binder){
    		//PropertyEditor
    		//类  implements  PropertyEditor
          //yyyy-MM-dd格式的时间 binder.registerCustomEditor(Date.class, new CustomDateEditor(new SimpleDateFormat("yyyy-MM-dd"), true)); } @RequestMapping("/first.do") //类型转化工作一定是在真正的handler方法执行前执行的。 public String doFirst(Date birthday,int age) throws Exception{ System.out.println(birthday+"==============="); System.out.println(age+"==============="); return "/WELCOME.jsp"; } }

applicationContext.xml配置  包扫描器
