在上篇中寫的僅僅支持寫屬性，不支持標簽property的寫法，可是假設有時候我們還想做成支持 property的使用方法，則能夠在xsd中添加spring 自帶的xsd引用

改動xsd文件例如以下：

<?xml version="1.0"encoding="UTF-8"?>
<xsd:schema xmlns="http://www.ruishenh.com/custom/myTest"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:beans="http://www.springframework.org/schema/beans"
    targetNamespace="http://www.ruishenh.com/custom/mytest"
    elementFormDefault="qualified" attributeFormDefault="unqualified">
    <xsd:import namespace="http://www.springframework.org/schema/beans"/>
    <xsd:element name="executor">
        <xsd:complexType>
            <xsd:complexContent>
                <xsd:extension base="beans:identifiedType">
                    <xsd:group ref="beans:beanElements" />
                    <xsd:attribute name="name" type="xsd:string"/>
                    <xsd:attribute name="delay" type="xsd:int"/>
                    <xsd:attribute name="interval" type="xsd:int"/>
                    <xsd:attribute name="address" type="xsd:string"/>
                    <xsd:attribute name="entity" type="xsd:string"/>
                </xsd:extension>
            </xsd:complexContent>
        </xsd:complexType>
    </xsd:element>
    <xsd:element name="entity">
        <xsd:complexType>
            <xsd:complexContent>
                <xsd:extension base="beans:identifiedType">
                    <xsd:group ref="beans:beanElements" />
                    <xsd:attribute name="name" type="xsd:string"/>
                    <xsd:attribute name="splitBy" type="xsd:string"/>
                    <xsd:attribute name="sql" type="xsd:string"/>
                    <xsd:attribute name="dbTypeID">
                        <xsd:simpleType>
                            <xsd:restriction base="xsd:int">
                                <xsd:enumeration value="1" />
                                <xsd:enumeration value="2" />
                                <xsd:enumeration value="3" />
                            </xsd:restriction>
                        </xsd:simpleType>
                    </xsd:attribute>
                    <xsd:attribute name="dbTypeName">
                        <xsd:simpleType>
                            <xsd:restriction base="xsd:string">
                                <xsd:enumeration value="mysql" />
                                <xsd:enumeration value="oracle" />
                                <xsd:enumeration value="sqlserver" />
                            </xsd:restriction>
                        </xsd:simpleType>
                    </xsd:attribute>
                </xsd:extension>
            </xsd:complexContent>
        </xsd:complexType>
    </xsd:element>
</xsd:schema>
 

改動BeanDefinitionPaser例如以下

package com.ruishenh.spring.config;
 
import java.util.List;
 
public class MyBeanDefinitionParser2 extends AbstractSingleBeanDefinitionParser {
 
    private Class<?> clssze;
 
    public MyBeanDefinitionParser2(Class<?
> cls) {
        this.clssze = cls;
    }
 
    @Override
    protected String getBeanClassName(Element element) {
        return clssze.getName();
    }
 
    @Override
    protected void doParse(Elementelement, ParserContext parserContext, BeanDefinitionBuilder builder) {
        List<Element> els = DomUtils.getChildElements(element);
        NamedNodeMap nnm = element.getAttributes();
        for (int i = 0; i <nnm.getLength(); i++) {
            Node node = nnm.item(i);
            String key = node.getLocalName();
            String value = node.getNodeValue();
            if ("id".equals(key)) {
                continue;
            }
            if ("entity".equals(key)){
                if(parserContext.getRegistry().containsBeanDefinition(value)) {
                    builder.addPropertyValue(key,parserContext.getRegistry().getBeanDefinition(value));
                }else{
                    builder.addPropertyReference(key,value);
                }
            }else{
                builder.addPropertyValue(key,value);
            }
        }
        for (Element element2 :els) {
            String name = element2.getAttribute("name");
            String value = element2.getAttribute("value");
            String ref = element2.getAttribute("ref");
            if (!StringUtils.hasText(ref)){
                builder.addPropertyValue(name,value);
            }else{
                if(parserContext.getRegistry().containsBeanDefinition(ref)) {
                    builder.addPropertyValue(name,parserContext.getRegistry().getBeanDefinition(ref));
                }else{
                    builder.addPropertyReference(name,ref);
                }
            }
        }
 
    }
}
 
 
 

SpringBean的Xml改動成例如以下：

<?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:mi="http://www.ruishenh.com/custom/mytest"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.ruishenh.com/custom/mytesthttp://www.ruishenh.com/custom/mytest/myTest2.xsd">
 
    <mi:executor address="127.0.0.1" name="myexecutor"id="myexecutor">
        <property name="interval" value="5000"/>
        <property name="delay" value="2000"/>
        <property name="entity" ref="mye"/>
    </mi:executor>
    <mi:executor address="192.168.201.23" name="myexecutor2"
        id="myexecutor2" entity="mye2">
        <property name="interval" value="5000"/>
        <property name="delay" value="2000"/>
    </mi:executor>
    <mi:entity name="mye" id="mye">
        <property name="dbTypeID" value="1"/>
        <property name="dbTypeName" value="mysql" />
        <property name="splitBy" value="id"/>
        <property name="sql" value="1"/>
    </mi:entity>
    <mi:entity name="mye2" id="mye2">
        <property name="dbTypeID" value="2"/>
        <property name="dbTypeName" value="oracle" />
        <property name="splitBy" value="orderId"/>
        <property name="sql" value="select * fromtablename" />
    </mi:entity>
</beans>
 

測試類：

packagecom.ruishenh.spring.test;
 
importorg.springframework.context.support.FileSystemXmlApplicationContext;
 
importcom.ruishenh.spring.config.MyEntity;
importcom.ruishenh.spring.config.MyExecutor;
 
publicclass Test {
    public static void main(String[] args) {
        String conf ="classpath:spring/myTest2.xml";
        FileSystemXmlApplicationContext ac = newFileSystemXmlApplicationContext(conf);
        MyExecutor me = (MyExecutor)ac.getBean("myexecutor2");
        MyExecutor me2 = (MyExecutor)ac.getBean("myexecutor");
        System.out.println(me.toString());
        System.out.println(me2.toString());
        MyEntity mye = (MyEntity) ac.getBean("mye");
        MyEntity mye2 = (MyEntity)ac.getBean("mye2");
        System.out.println(mye.toString());
        System.out.println(mye2.toString());
    }
}

執行結果：

MyExecutor[name=myexecutor2,delay=2000,interval=5000,address=192.168.201.23,entity=MyEntity[dbTypeID=2,dbTypeName=oracle,splitBy=orderId,sql=select* from tablename,name=mye2]]

MyExecutor[name=myexecutor,delay=2000,interval=5000,address=127.0.0.1,entity=MyEntity[dbTypeID=1,dbTypeName=mysql,splitBy=id,sql=1,name=mye]]

MyEntity[dbTypeID=1,dbTypeName=mysql,splitBy=id,sql=1,name=mye]

MyEntity[dbTypeID=2,dbTypeName=oracle,splitBy=orderId,sql=select* from tablename,name=mye2]
