springmvc在接收Date型表单的时候会报400
需要指定具体的类型编辑器。
1.在BaseController中增加方法initBinder,并使用注解@InitBinder标注,那么spring mvc在绑定表单之前,都会先注册这些编辑器。剩下的控制器都继承该类。
@InitBinder public void initBinder(WebDataBinder binder) { SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd"); dateFormat.setLenient(false); binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, false)); }
2.实现WebBindingInitializer
/**
Initialize web bindings */ public class MyAppBindingInitializer implements WebBindingInitializer {
/**
- Date pattern applied to all the web app dates */ public static final String DATE_PATTERN = "yyyy-MM-dd"
public void initBinder(WebDataBinder binder, WebRequest request) { // Date editor with pattern SimpleDateFormat dateFormat = new SimpleDateFormat(DATE_PATTERN); dateFormat.setLenient(false); binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, false));
// Trim Strings binder.registerCustomEditor(String.class, new StringTrimmerEditor(true)); // Number editors binder.registerCustomEditor(Integer.class, new CustomNumberEditor(Integer.class, true)); binder.registerCustomEditor(Long.class, new CustomNumberEditor(Long.class, true)); // Custom types binder.registerCustomEditor(Profile.class, new ProfileEditor()); binder.registerCustomEditor(OrderType.class, new OrderTypeEditor());
}
}
在xml里注册
<!-- Binder used to convert strings to other types in the web tier --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property name="webBindingInitializer"> <bean class="my.app.MyAppBindingInitializer "/> </property> </bean>
