An IOC injection _JSP programming of date attributes and date formats by Setters method

This example also involves the adoption of multiple profiles in spring, as well as the injection of date formats-------more flexible
Date Attribute class: Datepropertyinjection.java

Copy Code code as follows:

Package com.zhmg.spring;
Import Java.util.Date;
public class Datepropertyinjection {
private date date;
Public Date getDate () {
return date;
}
public void setdate (date date) {
This.date = date;
}
}

Property Editor Class: Propertyeditor.java

Copy Code code as follows:

Package com.zhmg.spring;
Import Java.beans.PropertyEditorSupport;
Import java.text.ParseException;
Import Java.text.SimpleDateFormat;
Import Java.util.Date;
/**
* Custom Property Editor handles properties of java.util.Date type
* @author Administrator
*
*/
public class PropertyEditor extends PropertyEditorSupport {
String format = "YYYY-MM-DD";
public void SetFormat (String format) {
This.format = format;
}
@Override
public void Setastext (String arg0) throws IllegalArgumentException {
SimpleDateFormat DateFormat = new SimpleDateFormat (format);
try {
Date date = Dateformat.parse (arg0);
This.setvalue (date);
catch (ParseException e) {
TODO auto-generated Catch block
E.printstacktrace ();
}
}
}

Test Unit: Injectiontest.java

Copy Code code as follows:

package com.zhmg.spring;
Import junit.framework.TestCase;
Import org.springframework.beans.factory.BeanFactory;
Import Org.springframework.context.support.ClassPathXmlApplicationContext;
public class Injectiontest extends TestCase {
Beanfactory factory;
protected void SetUp () throws Exception {
///wildcard to read all configuration files that start with ApplicationContext
Factory = new ClassPath Xmlapplicationcontext ("Applicationcontext*.xml");
}
public void Testinjection () {
Datepropertyinjection Dateprop = (datepropertyinjection) Factory.getbean ("D Ateproperty ");
System.out.println ("date=" + dateprop.getdate ());
}
}
