Grails时间类型自动转换的格式设置(inout)

概述1.Domain转换为json简单,直接在BootStrap的init里面添加: JSON.registerObjectMarshaller(Date) { return it?.format("yyyy-MM-dd HH:mm:ss")}   ps:还有一种方法是利用插件,重写Date的toString方法. 参见:http://stackoverflow.com/question

1.Domain转换为Json简单,直接在bootstrap的init里面添加:

JsON.registerObjectMarshaller(Date) {    return it?.format("yyyy-MM-dd HH:mm:ss")}

 

ps:还有一种方法是利用插件,重写Date的toString方法.

2.Js段提交数据到controller,自动转换为DATE.

 

1)在src/groovy添加:

package utilsimport java.beans.propertyeditorSupport;import java.text.ParseException;import java.text.SimpleDateFormat;/** * 自定义的Date转换器,支持多种format */class CustomDateBinder extends propertyeditorSupport {	private final List<String> formats;		public CustomDateBinder(List formats) {		List<String> formatList = new ArrayList<String>(formats.size());		for (Object format : formats) {			formatList.add(format.toString()); // Force String values (eg. for GStrings)		}		this.formats = Collections.unmodifiableList(formatList);	}	@OverrIDe	public voID setAsText(String s) throws IllegalArgumentException {		if (s != null)			for (String format : formats) {				// Need to create the SimpleDateFormat every time,since it's not thead-safe				SimpleDateFormat df = new SimpleDateFormat(format);				try {					setValue(df.parse(s));					return;				} catch (ParseException e) {					// Ignore				}			}	}}

 

2)添加CustompropertyeditorRegistrar:

package utilsimport grails.util.GrailsConfig;import java.text.SimpleDateFormat;import org.springframework.beans.propertyeditorRegistrar;import org.springframework.beans.propertyeditorRegistry;/** * 注册自定义的属性装配器 * @author TZ * */class CustompropertyeditorRegistrar implements propertyeditorRegistrar {	@OverrIDe	public voID registerCustomEditors(propertyeditorRegistry registry) { 		def formats = GrailsConfig.get("grails.date.formats",List.class)?:["yyyy-MM-dd HH:mm:ss","yyyy-MM-dd'T'HH:mm:ss","yyyy-MM-dd"];		registry.registerCustomEditor(Date.class,new CustomDateBinder(formats)); 	} }

 

3)在conf/spring/resources.groovy中注册:

beans = {	bean {		//自定义属性绑定		custompropertyeditorRegistrar(utils.CustompropertyeditorRegistrar)	  }}

 

4)conf/Config.groovy中添加配置:

grails.date.formats = ["yyyy-MM-dd HH:mm:ss","yyyy-MM-dd","yyyy-MM-dd HH:mm:ss.SSS ZZZZ","dd.MM.yyyy HH:mm:ss"];
