SSH企業(yè)培訓(xùn)之Spring組件裝配.ppt

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) 自動裝配 抽象配置,本章目標,集合裝配,public class CollectionInjectionService private String strValue; private int intValue; private List listValue; private String arrayValue; private Set setValue; private Map mapValue; private Date dateValue; /getXxx()與setXxx()方法 ,集合裝配, aaa bbb xxx

2、 yyy 數(shù)組與List配置方式一樣。,集合裝配, abc cba bac ,Main,ApplicationContext ctx=new ClassPathXmlApplicationContext(applicationContext.xml); CollectionInjectionService collectionInjectionService=(CollectionInjectionService)ctx.getBean(collectionInjectionService); System.out.println(collectionInjectionService.getS

3、trValue(); System.out.println(collectionInjectionService.getIntValue(); System.out.println(collectionInjectionService.getListValue(); System.out.println(collectionInjectionService.getArrayValue()2); System.out.println(collectionInjectionService.getSetValue(); System.out.println(collectionInjectionSe

4、rvice.getMapValue();,自定義屬性編輯器, 2009-03-25 步驟： 繼承PropertyEditorSupport類，覆蓋setAsText() 。 將屬性編輯器注冊到spring中。,DateUtilPropertyEditor,public class DateUtilPropertyEditor extends PropertyEditorSupport private String format=yyyy-MM-dd; public void setAsText(String text) throws IllegalArgumentException Simpl

5、eDateFormat sdf = new SimpleDateFormat(format); try Date d = sdf.parse(text); this.setValue(d); catch (ParseException e) e.printStackTrace(); ,自定義屬性編輯器-注冊到Spring, ,自動裝配,byName:根據(jù)名字自動裝配。 byType:根據(jù)類型自動裝配。 constructor:根據(jù)構(gòu)造器自動裝配。 autodetect:自動檢測自動裝配方式。 no:不采取自動裝配方式。 default:為no。 不是很贊同使用自動裝配方式。,AutowireS

6、ervice類,public class AutowireService CollectionInjectionService collectionInjectionService; public CollectionInjectionService getCollectionInjectionService() return collectionInjectionService; public void setCollectionInjectionService( CollectionInjectionService collectionInjectionService) this.collectionInjectionService = collectionInjectionService; public void call()System.out.println(collectionInjectionService.getListValue(); ,自動裝配byName, - 效果一樣。,抽象配置,通過定義公共的屬性，指定abstract=true 具有相同屬性的類在標簽中指定其parent屬性 可以重用屬性配置。 ,Son類,public class Son private In
