需求：将Customer中address属性的值赋值给Address类中的每一个属性

package com.atguigu.selfEditor;public class Address {private String province;private String city;private String town;public String getProvince() {return province;}public void setProvince(String province) {this.province = province;}public String getCity() {return city;}public void setCity(String city) {this.city = city;}public String getTown() {return town;}public void setTown(String town) {this.town = town;}@Overridepublic String toString() {return "Address{" +"province='" + province + '\'' +", city='" + city + '\'' +", town='" + town + '\'' +'}';}
}

package com.atguigu.selfEditor;public class Customer {private Address address;private String name;public Address getAddress() {return address;}public void setAddress(Address address) {this.address = address;}public String getName() {return name;}public void setName(String name) {this.name = name;}@Overridepublic String toString() {return "Customer{" +"address=" + address +", name='" + name + '\'' +'}';}
}

package com.atguigu.selfEditor;import java.beans.PropertyEditorSupport;public class AddressPropertyEditor extends PropertyEditorSupport {@Overridepublic void setAsText(String text) throws IllegalArgumentException {String[] s = text.split("_");Address address = new Address();address.setProvince(s[0]);address.setCity(s[1]);address.setTown(s[2]);this.setValue(address);}}

package com.atguigu.selfEditor;import org.springframework.beans.PropertyEditorRegistrar;
import org.springframework.beans.PropertyEditorRegistry;public class AddressPropertyEditorRegistrar implements PropertyEditorRegistrar {@Overridepublic void registerCustomEditors(PropertyEditorRegistry registry) {registry.registerCustomEditor(Address.class,new AddressPropertyEditor());}
}

public class App {public static void main(String[] args) {ApplicationContext context = new ClassPathXmlApplicationContext("selfEditor.xml");Customer user = (Customer)context.getBean(Customer.class);System.out.println(user);}
}
output:
Customer{address=Address{province='河北省', city='邯郸市', town='武安市'}, name='zhangsan'}
