1、劉曉濤Spring組件裝配集合裝配自定義屬性編輯器(日期處理)自動(dòng)裝配抽象配置本章目標(biāo)集合裝配publicclassCollectionInjectionService{privateStringstrValue;privateintintValue;privateListlistValue;privateString[]arrayValue;privateSetsetValue;privateMapmapValue;privateDatedateValue;//getXxx()與setXxx()方法}集合裝配

2、e="strValue"value="hellolxt008!!!">aaabbbxxxyyy數(shù)組與Li

3、st配置方式一樣。集合裝配abccbabacMainApplic

4、ationContextctx=newClassPathXmlApplicationContext("applicationContext.xml");CollectionInjectionServicecollectionInjectionService=(CollectionInjectionService)ctx.getBean("collectionInjectionService");System.out.println(collectionInjectionService.getStrValue());System.out

5、.println(collectionInjectionService.getIntValue());System.out.println(collectionInjectionService.getListValue());System.out.println(collectionInjectionService.getArrayValue()[2]);System.out.println(collectionInjectionService.getSetValue());System.out.println(collectionI

6、njectionService.getMapValue());自定義屬性編輯器2009-03-25步驟：繼承PropertyEditorSupport類，覆蓋setAsText()。將屬性編輯器注冊(cè)到spring中。DateUtilPropertyEditorpublicclassDateUtilPropertyEditorextendsPropertyEditorSuppo

7、rt{privateStringformat="yyyy-MM-dd";publicvoidsetAsText(Stringtext)throwsIllegalArgumentException{SimpleDateFormatsdf=newSimpleDateFormat(format);try{Dated=sdf.parse(text);this.setValue(d);}catch(ParseExceptione){e.printStackTrace();}}}自定義屬性編輯器-注冊(cè)到Spring
