1. 新建员工类，他有电话号码和出生日期等信息

package com.chapter3.getterdi;import java.util.Date;public class Employee{int id;String name;PhoneNumber phoneNumber;Date birthDate;public int getId(){return id;}public void setId(int id){this.id = id;}public String getName(){return name;}public void setName(String name){this.name = name;}public PhoneNumber getPhoneNumber(){return phoneNumber;}public void setPhoneNumber(PhoneNumber phoneNumber){this.phoneNumber = phoneNumber;}public Date getBirthDate(){return birthDate;}public void setBirthDate(Date birthDate){this.birthDate = birthDate;}}

2. 新建PhoneNumber类

package com.chapter3.getterdi;public class PhoneNumber{String areaNumber;String telNumber;@Overridepublic String toString(){return areaNumber + "-" + telNumber;}public String getAreaNumber(){return areaNumber;}public void setAreaNumber(String areaNumber){this.areaNumber = areaNumber;}public String getTelNumber(){return telNumber;}public void setTelNumber(String telNumber){this.telNumber = telNumber;}}

3. 新建属性编辑器

package com.chapter3.getterdi;import java.beans.PropertyEditorSupport;public class PhoneEditor extends PropertyEditorSupport{@Overridepublic void setAsText(String text) throws IllegalArgumentException{PhoneNumber phoneNumber = new PhoneNumber();String[] str = text.split("-");phoneNumber.setAreaNumber(str[0]);phoneNumber.setTelNumber(str[1]);setValue(phoneNumber);}}

4.新建日期的属性编辑器

package com.chapter3.getterdi;import java.beans.PropertyEditorSupport;import java.text.ParseException;import java.text.SimpleDateFormat;public class DateEditor extends PropertyEditorSupport{String dateFormat;public String getDateFormat(){return dateFormat;}public void setDateFormat(String dateFormat){this.dateFormat = dateFormat;}@Overridepublic void setAsText(String text) throws IllegalArgumentException{SimpleDateFormat format = new SimpleDateFormat(dateFormat);try{setValue(format.parse(text));} catch (ParseException e){e.printStackTrace();}}}

5. Spring的配置文件

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd"><bean class="org.springframework.beans.factory.config.CustomEditorConfigurer"><property name="customEditors"><map><entry key="com.chapter3.getterdi.PhoneNumber"><bean id="phoneEditor" class="com.chapter3.getterdi.PhoneEditor"/></entry><entry key="java.util.Date"><bean id="dateEditor" class="com.chapter3.getterdi.DateEditor"><property name="dateFormat" value="yyyy-MM-dd"/></bean></entry></map></property></bean><bean id="employee" class="com.chapter3.getterdi.Employee"><property name="id" value="1"/><property name="name" value="张三"/><property name="phoneNumber" value="025-8630471"/><property name="birthDate" value="1983-10-10"/></bean></beans><?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd"><bean class="org.springframework.beans.factory.config.CustomEditorConfigurer"><property name="customEditors"><map><entry key="com.chapter3.getterdi.PhoneNumber"><bean id="phoneEditor" class="com.chapter3.getterdi.PhoneEditor"/></entry><entry key="java.util.Date"><bean id="dateEditor" class="com.chapter3.getterdi.DateEditor"><property name="dateFormat" value="yyyy-MM-dd"/></bean></entry></map></property></bean><bean id="employee" class="com.chapter3.getterdi.Employee"><property name="id" value="1"/><property name="name" value="张三"/><property name="phoneNumber" value="025-8630471"/><property name="birthDate" value="1983-10-10"/></bean></beans><?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd"><bean class="org.springframework.beans.factory.config.CustomEditorConfigurer"><property name="customEditors"><map><entry key="com.chapter3.getterdi.PhoneNumber"><bean id="phoneEditor" class="com.chapter3.getterdi.PhoneEditor"/></entry><entry key="java.util.Date"><bean id="dateEditor" class="com.chapter3.getterdi.DateEditor"><property name="dateFormat" value="yyyy-MM-dd"/></bean></entry></map></property></bean><bean id="employee" class="com.chapter3.getterdi.Employee"><property name="id" value="1"/><property name="name" value="张三"/><property name="phoneNumber" value="025-8630471"/><property name="birthDate" value="1983-10-10"/></bean></beans><?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd"><bean class="org.springframework.beans.factory.config.CustomEditorConfigurer"><property name="customEditors"><map><entry key="com.chapter3.getterdi.PhoneNumber"><bean id="phoneEditor" class="com.chapter3.getterdi.PhoneEditor"/></entry><entry key="java.util.Date"><bean id="dateEditor" class="com.chapter3.getterdi.DateEditor"><property name="dateFormat" value="yyyy-MM-dd"/></bean></entry></map></property></bean><bean id="employee" class="com.chapter3.getterdi.Employee"><property name="id" value="1"/><property name="name" value="张三"/><property name="phoneNumber" value="025-8630471"/><property name="birthDate" value="1983-10-10"/></bean></beans>

6. 测试类

package com.chapter3.getterdi;import java.lang.reflect.Field;import java.lang.reflect.InvocationTargetException;import org.apache.commons.beanutils.BeanUtils;import org.springframework.beans.factory.BeanFactory;import org.springframework.context.support.ClassPathXmlApplicationContext;public class Test{public static void main(String[] args){BeanFactory factory = new ClassPathXmlApplicationContext("springchapter3.xml");Employee employee = (Employee) factory.getBean("employee");Field[] fields = employee.getClass().getDeclaredFields();for (int i = 0; i < fields.length; i++){try{System.out.println(fields[i].getName() + " : " + BeanUtils.getProperty(employee, fields[i].getName()));} catch (IllegalAccessException e){e.printStackTrace();} catch (InvocationTargetException e){e.printStackTrace();} catch (NoSuchMethodException e){e.printStackTrace();}}}}
