Spring自定义属性编辑器

自定义Spring属性编辑器
流程：1,编写被解析类和解析类Address,Customer;
     2,定义一个属性编辑器AddressPropertyEditor,继承于PropertyEditorSupport类，重写里面setAsText()方法;
     3,定义一个属性编辑器注册器AddressPropertyEditorRegistrar,继承于PropertyEditorRegistrar类，重写里面registerCustomEditors()方法;
     4,编写配置文件selfEditor.xml,两种配置方式，一种为propertyEditorRegistrars，另外一种customEditors;
     5,编写测试类TestSelfEditor

1,编写实体类

Address.java

package com.mashibing.selfEditor;

public class Address {
    private String provice;
    private String city;
    private String town;

    public String getProvice() {
        return provice;
    }

    public void setProvice(String provice) {
        this.provice = provice;
    }

    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;
    }

    @Override
    public String toString() {
        return "Address{" +
                "provice='" + provice + '\'' +
                ", city='" + city + '\'' +
                ", town='" + town + '\'' +
                '}';
    }
}
Customer.java
2、定义属性编辑器
AddressPropertyEditor.java

package com.mashibing.selfEditor;

import java.beans.PropertyEditorSupport;

public class AddressPropertyEditor extends PropertyEditorSupport {
    
    @Override
    public void setAsText(String text) throws IllegalArgumentException {
       String[] s=text.split("_");
       Address address=new Address();
       address.setProvice(s[0]);
       address.setCity(s[1]);
       address.setCity(s[2]);
       this.setValue(address);
    }
}
3、定义属性编辑注册器

AddressPropertyEditorRegistrar.java

package com.mashibing.selfEditor;

import org.springframework.beans.PropertyEditorRegistrar;
import org.springframework.beans.PropertyEditorRegistry;

public class AddressPropertyEditorRegistrar implements PropertyEditorRegistrar {
    @Override
    public void registerCustomEditors(PropertyEditorRegistry propertyEditorRegistry) {
        propertyEditorRegistry.registerCustomEditor(Address.class,new AddressPropertyEditor());
    }
}
4、配置文件
selfEditor.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

    <bean id="customer" class="com.mashibing.selfEditor.Customer">
        <property name="name" value="qiangShan"></property>
        <property name="address" value="江西省_抚州市_南城县"></property>
    </bean>

   <!-- <bean id="customEditorConfigurer" class="org.springframework.beans.factory.config.CustomEditorConfigurer">
        <property name="propertyEditorRegistrars">
            <list>
                <bean id="addressPropertyEditorRegistrar" class="com.mashibing.selfEditor.AddressPropertyEditorRegistrar"></bean>
            </list>
        </property>
    </bean>-->
    <bean id="customEditorConfigurer" class="org.springframework.beans.factory.config.CustomEditorConfigurer">
        <property name="customEditors">
            <map>
                <entry key="com.mashibing.selfEditor.Address">
                    <value>com.mashibing.selfEditor.AddressPropertyEditor</value>
                </entry>
            </map>
        </property>
    </bean>
</beans>
5、测试类
TestSelfEditor.java

import com.mashibing.selfEditor.Customer;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestSelfEditor {

    @Test
    public void test(){
        ApplicationContext context=new ClassPathXmlApplicationContext("selfEditor.xml");
        Customer customer = context.getBean("customer", Customer.class);
        System.out.println(customer);
    }
}
