本例的全部源代码：

1. 定义XSD文件：

2. 设置：spring.handlers

http\://www.37link.com/schema/scf=com.mm.spring_ext.MyNamespaceHandler

3. 设置：spring.schemas

http\://www.37link.com/schema/scf/scf.xsd=com/mm/spring_ext/scf.xsd

4. 定义spring对自定义的命名空间进行解析的操作

package com.mm.spring_ext;import java.util.ArrayList;import java.util.List;import org.springframework.beans.factory.support.BeanDefinitionBuilder;import org.springframework.beans.factory.xml.AbstractSingleBeanDefinitionParser;import org.springframework.util.StringUtils;import org.w3c.dom.Element;import org.w3c.dom.Node;import org.w3c.dom.NodeList;public class PeopleBeanDefinitionParser extends AbstractSingleBeanDefinitionParser {	protected Class getBeanClass(Element element) {		return People.class;	}	protected void doParse(Element element, BeanDefinitionBuilder bean) {		String name = element.getAttribute("name");		String age = element.getAttribute("age");		String id = element.getAttribute("id");		NodeList elementSons = element.getChildNodes();		if (StringUtils.hasText(id)) {			bean.addPropertyValue("id", id);		}		if (StringUtils.hasText(name)) {			bean.addPropertyValue("name", name);		}		if (StringUtils.hasText(age)) {			bean.addPropertyValue("age", Integer.valueOf(age));		}		if (elementSons != null && elementSons.getLength() > 0) {			List
    
      list = new ArrayList
     
      ();			for (int i = 0; i < elementSons.getLength(); i++) {				Node node = elementSons.item(i);				if (node instanceof Element) {					if ("own".equals(node.getNodeName()) || "own".equals(node.getLocalName())) {						String value = ((Element) node).getAttribute("value");						list.add(value);					}				}			}			bean.addPropertyValue("own", list);		}	}}
     
    

5.将解析类注册到命名空间中的实现

package com.mm.spring_ext;import org.springframework.beans.factory.xml.NamespaceHandlerSupport;public class MyNamespaceHandler extends NamespaceHandlerSupport {	public void init() {		registerBeanDefinitionParser("student", new PeopleBeanDefinitionParser());	}}

 6.定义需要spring管理bean的实体 People.java

package com.mm.spring_ext;import java.util.List;public class People {	private String id;	private String name;	private Integer age;	private List
    
      own;	public String getId() {		return id;	}	public void setId(String id) {		this.id = id;	}	public String getName() {		return name;	}	public void setName(String name) {		this.name = name;	}	public Integer getAge() {		return age;	}	public void setAge(Integer age) {		this.age = age;	}	public List
     
       getOwn() {		return own;	}	public void setOwn(List
      
        own) {		this.own = own;	}}
      
     
    

7. 然后配置spring的xml配置文件test.xml

8. 最后写一个测试类，简单起见，直接用main函数的方式

package com.mm.spring_ext_test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.mm.spring_ext.People;public class AppTest {	public static void main(String[] args) {		ApplicationContext ctx = new ClassPathXmlApplicationContext("test.xml");		People f = (People) ctx.getBean("scf1");		if (f != null && f.getOwn() != null && f.getOwn().size() > 0) {			for (String own : f.getOwn()) {				System.out.println(own);			}		}	}}
