Springmvc one of the date format value resolution methods (total two) @DateTimeFormat usage and configuration

Inadvertently found that for the time string to date class, do not have to write their own conversion class, Spring MVC has implemented this feature, or annotation-based, easy and convenient, using Org.springframework.format.support.FormattingConversionServiceFactoryBean
After that, just add a note to VO.

To introduce a class library when using Joda-time-n.n.jar

Java code

1. @DateTimeFormat (pattern="Yyyy-mm-dd")
2. Private Date Daterangestart; //Date range start

@DateTimeFormat (pattern= "YYYY-MM-DD") converts a string of a shape like 1980-0-01 to a date class
@NumberFormat (pattern= "#,###.##") converts a string of the form 4,500.00 to a long type

How to register it?

Java code

1. <bean id="Conversionservice"
2. class="Org.springframework.format.support.FormattingConversionServiceFactoryBean" >
3. <mvc:annotation-driven validator="Validator"
4. conversion-service="Conversionservice"/>

With <mvc:annotation-driven/>, Formattingconversionservicefactorybean is enabled by default, so the above configuration is also saved.
But <mvc:annotation-driven/> Basic not, because must do some personalization, then how to register Formattingconversionservicefactorybean to spring MVC?
At first I thought I had to start from defaultannotationhandlermapping, and then by looking at <mvc:annotation-driven/> Parser Annotationdrivenbeandefinitionparser Source, only to find that the original is the Annotationmethodhandleradapter attribute

Java code

2. Runtimebeanreference Conversionservice = Getconversionservice (element, source, parsercontext);
4. Runtimebeanreference validator = Getvalidator (element, source, parsercontext);
8. Rootbeandefinition bindingdef = new Rootbeandefinition (Configurablewebbindinginitializer.   Class);
10. Bindingdef.setsource (source);
12. Bindingdef.setrole (beandefinition.role_infrastructure);
14. Bindingdef.getpropertyvalues (). Add ("Conversionservice", Conversionservice);
16. Bindingdef.getpropertyvalues (). Add ("validator", validator);
20. Rootbeandefinition annadapterdef = new Rootbeandefinition (Annotationmethodhandleradapter.   Class);
22. Annadapterdef.setsource (source);
24. Annadapterdef.setrole (beandefinition.role_infrastructure);
26. Annadapterdef.getpropertyvalues (). Add ("Webbindinginitializer", bindingdef);
28. Annadapterdef.getpropertyvalues (). Add ("Messageconverters", getmessageconverters (source));

Getconversionservice Method Interior

Java code

2. if (Element.hasattribute ("Conversion-service")) {
4. return New Runtimebeanreference (Element.getattribute ("Conversion-service"));
6. }
8. else {
10. Rootbeandefinition conversiondef = new Rootbeandefinition (Formattingconversionservicefactorybean.   Class);
12. Conversiondef.setsource (source);
14. Conversiondef.setrole (beandefinition.role_infrastructure);
16. String conversionname = Parsercontext.getreadercontext (). Registerwithgeneratedname (Conversiondef);
18. Parsercontext.registercomponent (new Beancomponentdefinition (Conversiondef, conversionname));
20. return new Runtimebeanreference (Conversionname);
22. }

The original <mvc:annotation-driven/> is so registered Formattingconversionservicefactorybean
If you do not use the <mvc:annotation-driven/> tag, just configure the properties of the Annotationmethodhandleradapter.

<Beanclass= "Org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" >     <!--Support @datetimeformat (pattern= "Yyyy-mm-dd") and other annotations July 31, 2015 11:07:03 Liuyx -     < Propertyname= "Webbindinginitializer">      <Beanclass= "Org.springframework.web.bind.support.ConfigurableWebBindingInitializer">          < Propertyname= "Conversionservice">              <Beanclass= "Org.springframework.format.support.FormattingConversionServiceFactoryBean"></Bean>          </ Property>      </Bean>      </ Property> </Bean>
