1。创建自己的bean：beans.xml
<？xml版本=“ 1.0”编码=“ utf-8”？> <busi-beans> <beans> <bean id =“ syshelloimpl” type =“ com.cxm.test.syshello”> <desc> </desc> test </desc> test </desc> </desc> <spland-class> <spland-class> com.cxm.c com.cxm.cx.syshelloimpl </bues buean>
2。xml类：xmlutils
/** * */包com.cxm.xmlutil; import java.io.inputStream; import java.util.iterator; import java.util.map; import org.jdom.jdom.attribute; import org.jdom.jdom.jdom.jdom.jdom.document; import org.jdom.jdom.element; elemt org.jdody; eeld empt; com.cxm.beaninfo.BeanInfo;/** * @author admin * */public class XmlUtils{public static void parseXmlDef(InputStream in, Map<String,BeanInfo> beanDefMap,StringBuffer sb) throws Exception{SAXBuilder reader = new SAXBuilder(false);Document doc = null;try{doc = reader.build（in）; iterator beanit = xpath.selectNodes（doc，“/busi-beans/beans/beans/bean").iterator（eleterator(); element E; element e; eleminfo beandef; while while（beant.hasnext（）） e.getAttribute（“ id”）; attibute attrype = e.getAttribute（“ type”）; attribute singletype = e.getAttribute（“ single”）; boolean issingle = true; if（null！= singletype && &&＆＆＆&&“ 1” .equals（singletype.getValue（issingvalue（）） false;} beandef.setsingle（issingle）; beandef.setBeanid（attrid.getValue（））; beandef.settype（attrype.getValue（））; beandef.setBeandesc（getText（getText）（getText（e，e，d desc'd desc'd desc'） “ Impl-class”））; //处理初始化参数beandefmap.put（attrid.getValue（），beandef）;}}} catch（exudepion e）{e.printstacktrace（）;}}}}}}/** *根据指定的元素，xpath p_element，字符串p_xpath）抛出异常{字符串text = null; element e =（element）xpath.selectsinglenode（p_element，p_xpath）; if（e！= null）{text = e.getText（） 3. bean io
/** * */软件包com.cxm.beaninfo;/** * @author admin * */public class beaninfo {private string beanid; private string; private string beandesc; public string getBeanDesc（）{return beandesc;} type;} public void setType（string type）{this.type = type;}私有字符串inplclassName; public string getBeanId（）{return beanid;} public void setBeanId（string beanid）{this.beanid = beanid = beanid;} public string getimplclassname string InplClassName）{this.implClassName = inplclassName;} public boolean issingle（）{返回issingle;} public void setSingle（boolean issingle）{this.issingle = isingle = issingle;}私人布尔;} 4. Bean的创建类：Beanutil
/** * */package com.cxm.bean;/** * @author admin * */public class beanutil {private static xmlbeanfactory fartical = new xmlbeanfactory（） factory.createBean(p_beanId);}} /** * */package com.cxm.bean;import java.io.FileNotFoundException;import java.io.InputStream;import java.lang.reflect.Constructor;import java.util.HashMap;import java.util.Map;import com.cxm.beaninfo.beaninfo; import com.cxm.exception.nosuchbeandefinitionException; import com.cxm.cxm.xmlutil.xmlutils;/** * @Author admin */admin */admin */public class class class class class xmlbeanfactory xmlbeanfactory {private static Strate string bean_xml = beandefmap = new Hashmap <字符串，beaninfo>（）;私有静态映射<string，object> instancemap = new Hashmap <string，object>（）; static {inputStream in = xmlbeanfactory.class.class.getResresourceasourceasorceorceastream（bean_xml） （filenotfoundException e）{e.printstacktrace（）;}} stringBuffer sb = new StringBuffer（）; try {xmlutils.parsexmldef（in，beandefmap，sb）;} || beanId.trim()==""){throw new Exception("BeanId can not NULL or '' ");}BeanInfo beanInfo = beanDefMap.get(beanId);if(null ==beanInfo ){throw new NoSuchBeanDefinitionException(" beanid is not define in xml");}Object instance;if(beanInfo.isSingle()){instance = instancemap.get（beanid）; if（null！= instance）{return instance;}} string string inplclass = beaninfo.getImplClassName（）; structionor <？> structionor <？> classor = class.forname（inplclass.trim（） constructor.newinstance（）; if（beaninfo.issingle（））{instancemap.put（beanid，instance）;} return instance;}}}} 5。测试：
/** * */package com.cxm.test;/** * @author admin * */public interface SysHello{void sysHello();} /** * */package com.cxm.test;/** * @author admin * */public class SysHelloImpl implements SysHello{@Overridepublic void sysHello(){System.out.println("hello world！”）;}}}/** * */package com.cxm.test; import com.cxm.bean.beanutil;/** * @author Admin * */public class test {/** * @param args * @param args * @throws * @throws * @throws * @throws * @throws excrideion */public static void main（string [string] syshellos syshello s = syshello s = syshello s = syshello s = （syshello）beanutil.createbean（“ syshelloimpl”）; s.syshello（）;}}}以上这篇java spring在xml配置java类的方法就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持武林网。
