<？xml version = "1.0" encoding = "utf-8"？> <busi-beans> <beans> <bean id = "syshelloimpl" type = "com.cxm.test.syshello"> <desc> test </desc> <impl-crass> com.cxm.test.syshelloimpl </bean> </bean
2。xml类：xmlutils
/** * */パッケージcom.cxm.xmlutil; Import java.io.inputStream; Import java.util.iterator; Import java.util.map; Import org.jdom.attribute; import org.jdom.document; import org.jdom.element; Import org.jdom.daxbuilder.daxbuilder.daxbuilder.daxbuilder.daxbuilder.daxbuilder.daxbuilder.daxbuilder.daxbuilder.daxbuilder.daxbuilder. com.cxm.beaninfo.beaninfo;/** * @author admin * */public class xmlutils {public static void parsexmldef（inputstream in、map <string、beaninfo> beandefmap、stringbuffer sb）スロー例外reader.build（in）; iterator beanit = xpath.selectnodes（doc、 "/busi-beans/beans/bean"）.iterator(）; element e; beaninfo beandef; e.getAttribute（ "id"）; attribute atttype = e.getAttribute（ "type"）; attibute singletype = e.getattribute（ "single"）; boolean sissingle = true; if（null！= singletype && "1" .equals（singletype.getvalue（））{singingle = {sissingLe false;} beandef.setsingle（issingle）; beandef.setbeanid（attrid.getValue（））; beandef.settype（atttype.getValue（））; beandef.setbeandesc（gettext（e、 "desc"））; "Impl-class"））; // p_element、string p_xpath）スロー例外{string text = null; element e =（element）xpath.selectsinglenode（p_element、p_xpath）; if（e！= null）{text = e.getText（）;} else {} return text;}}}} 3. bean io
/*** * */パッケージcom.cxm.beaninfo;/** * @author admin * */public class beaninfo {private string beanid; private string type; private string beandesc; public beandesc（）{return beandesc;} public void setbeandesc（this beandesc = beandesc = beandesc = beandesc = beandesc = beandesc = beandesc = beandesc = beandesc getType（）{return type;} public void setType（string type）{this.type = type;} private string entlclassname; public string getbeanid（）{return beanid;} public void setbeanid（string beanid）{this.beanid = beanid;} public string getimplclclsname;} SetimplClassName（String ImplClassName）{this.implClassName = ImplClassName;} public Boolean Issingle（）{return Issingle;} public void setSingle（boolean issingle）{this.issingle = issingle;} private boolean issingle = true;} 4.ビーン的创建类：Beanutil
/** * */パッケージcom.cxm.bean;/** * @author admin * */public class beanutil {private xmlbeanfactory Factory = new XmlbeanFactory（）;/** *获取定义好的Bean Factory.createbean（p_beanid）;}} /** * * /package com.cxm.bean; import java.io.fileenotfoundexception; Import java.io.inputstream; import java.lang.reflect.constuctor; Import Java.util.util.util.Map; Import Java.Util.Map; com.cxm.beaninfo.beaninfo; Import com.cxm.exception.nosuchbeandefinitionexception;インポートcom.cxm.xmlutils;/** * @author admin * */public class xmlbeanfactory {private static string bean_xml = "/bbeans.xml purtingiate beandefmap = new Hashmap <String、Beaninfo>（）; private static Map <string、object> instancemap = new Hashmap = new Hashmap = new Hashmap = new Hashmap = new Hashmap = object>（）; static {inputstream in = xmlbeanfactory.class.getResourceasstream（ （filenotfoundexception e）{e.printstacktrace（）;}} stringbuffer sb = new stringbuffer（）; try {xmlutils.parsexmldef（in、beandefmap、sb）;} catch（exception e）{throw new runtimeexception（）;}}パブリックオブジェクトCreate createbuean（String bean（）例外{if（beanid == null || beanid.trim（）== ""）{throw new Exception（ "beanidはnullまたは ''"）;} beaninfo beaninfo = beandefmap.get（beanid）; if（null == beaninfo）{新しいnosuchbeandefinitionexception（define in xml ";" instance; if（beaninfo.issingle（））{instance = instancemap.get（beanid）; if（null！= instance）{return instance;}} string entlclass = beaninfo.getimplclassname（）; constructor <？> construction = class.forname（） constructor.newinstance（）; if（beaninfo.issingle（））{instancemap.put（beanid、instance）;} return instance;}}} 5。
/** * */パッケージcom.cxm.test;/** * @author admin * */public interface syshello {void syshello（）;}/** * */package com.cxm.test;/** * @author admin * */public class syshelloimpl実装syshello world！ "）;}}/** * */package com.cxm.test; import com.cxm.bean.beanutil;/** * @author admin * */public class test {/** * @param args */public static void main（string [] args）Throws Exception （syshello）beanutil.createbean（ "syshelloimpl"）; s.syshello（）;}}}以上这篇java实现春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。
