先贴出代码出来看看.
首先是一个Folders.xml文件: <?xml version="1.0" encoding="gbk"?> <Folders> <Folder stepid="5" beginEid="1.0.0." endEid="8.0.0." folderId="88" folderName="文件夹一" /> <Folder stepid="5" beginEid="8.0.0." endEid="20.0.0." folderId="89" folderName="文件夹二" /> </Folders> 一下是解析XML文件的类.采用jdom解析.然后封装到一个Bean对象中.最后返回一个ArrayList集合.集合里面是一个个Bean对象. XmlConfig.Java
package JdBudget.OuterWeb.Config;
import java.util.*;
import java.io.*;
import JdBudget.OuterWeb.bean.*;
import JdBudget.OuterWeb.bean.Folder;
import org.jdom.output.*;
import org.jdom.input.*;
import org.jdom.*;

public class XmlConfig {
public XmlConfig(){}
ArrayList dataList = null;
//解析Folders.xml
public ArrayList getFoldersInfo(String path) {
dataList = new ArrayList();
Folder dataValue = null;
try {
SAXBuilder builder = new SAXBuilder(false);
Document read_doc = builder.build(new FileInputStream(path));
Element root = read_doc.getRootElement();
List Folders = root.getChildren("Folder");
for (int i = 0; i < Folders.size(); i++) {
Element e = (Element) Folders.get(i);
dataValue = new Folder();
dataValue.setFolderId(e.getAttributeValue("folderId"));
dataValue.setEndEid(e.getAttributeValue("endEid"));
dataValue.setBeginEid(e.getAttributeValue("beginEid"));
dataValue.setStepid(e.getAttributeValue("stepid"));
System.out.println(e.getAttributeValue("folderId"));
System.out.println(e.getAttributeValue("folderName"));
System.out.println(e.getAttributeValue("endEid"));
System.out.println(e.getAttributeValue("beginEid"));
System.out.println(e.getAttributeValue("stepid"));
dataList.add(dataValue);
}
}
catch (Exception dom) {
System.out.println("getFoldersInfo Err" + dom.toString());
}
return dataList;
}
//解析Reports.xml
public ArrayList getReportsInfo(String path) {
dataList = new ArrayList();
Report dataValue = null;
try {
SAXBuilder builder = new SAXBuilder(false);
Document read_doc = builder.build(new FileInputStream(path));
Element root = read_doc.getRootElement();
List Reports = root.getChildren("Report");
for (int i = 0; i < Reports.size(); i++) {
Element e = (Element) Reports.get(i);
dataValue = new Report();
dataValue.setItemId(e.getAttributeValue("ItemId"));
dataValue.setVariant(e.getAttributeValue("Variant"));
dataValue.setType(e.getAttributeValue("Type"));
dataList.add(dataValue);
}
}
catch (Exception dom) {
System.out.println("getReportsInfo Err" + dom.toString());
}
return dataList;
}
public static void main(String[] args){
XmlConfig xmlconfig = new XmlConfig();
File f = new File("");
ArrayList list = new ArrayList();
list = xmlconfig.getFoldersInfo(f.getAbsolutePath()+f.separator+"MultiReport"+f.separator+"config"+f.separator+"Folders.xml");
}
}
我用XmlConfig.java文件中的main方法测试,能得到争取得解析结果 . 如: 88 文件夹一 8.0.0. 1.0.0. 5 89 文件夹二 20.0.0. 8.0.0. 5 但是当我在createreport.jsp里面调用执行 XmlConfig xConfig = new XmlConfig(); 时程序就已经报错误. 错误描述如下: D:\JBuilderX\jdk1.4\bin\javaw -classpath "D:\JBuilderX\thirdparty\jakarta-tomcat-4.0.6-LE-jdk14\bin\bootstrap.jar;D:\JBuilderX\jdk1.4\lib\tools.jar" -Dcatalina.home="D:/JBuilderX/thirdparty/jakarta-tomcat-4.0.6-LE-jdk14" org.apache.catalina.startup.Bootstrap -config E:\work\BatchPrint\MultiReport\Tomcat\conf\server8083.xml start HttpConnector Opening server socket on all host IP addresses Starting service Tomcat-Standalone Apache Tomcat/4.0.6 WebappLoader[/MultiReport]: Deploying class repositories to work directory E:\work\BatchPrint\MultiReport\Tomcat\work\MultiReport WebappLoader[/MultiReport]: Deploy JAR /WEB-INF/lib/activation.jar to E:\work\BatchPrint\MultiReport\MultiReport\WEB-INF\lib\activation.jar WebappLoader[/MultiReport]: Deploy JAR /WEB-INF/lib/axis-ant.jar to E:\work\BatchPrint\MultiReport\MultiReport\WEB-INF\lib\axis-ant.jar WebappLoader[/MultiReport]: Deploy JAR /WEB-INF/lib/axis.jar to E:\work\BatchPrint\MultiReport\MultiReport\WEB-INF\lib\axis.jar WebappLoader[/MultiReport]: Deploy JAR /WEB-INF/lib/classes12.jar to E:\work\BatchPrint\MultiReport\MultiReport\WEB-INF\lib\classes12.jar WebappLoader[/MultiReport]: Deploy JAR /WEB-INF/lib/commons-discovery.jar to E:\work\BatchPrint\MultiReport\MultiReport\WEB-INF\lib\commons-discovery.jar WebappLoader[/MultiReport]: Deploy JAR /WEB-INF/lib/commons-logging.jar to E:\work\BatchPrint\MultiReport\MultiReport\WEB-INF\lib\commons-logging.jar WebappLoader[/MultiReport]: Deploy JAR /WEB-INF/lib/jaxrpc.jar to E:\work\BatchPrint\MultiReport\MultiReport\WEB-INF\lib\jaxrpc.jar WebappLoader[/MultiReport]: Deploy JAR /WEB-INF/lib/junit.jar to E:\work\BatchPrint\MultiReport\MultiReport\WEB-INF\lib\junit.jar WebappLoader[/MultiReport]: Deploy JAR /WEB-INF/lib/log4j-1.2.8.jar to E:\work\BatchPrint\MultiReport\MultiReport\WEB-INF\lib\log4j-1.2.8.jar WebappLoader[/MultiReport]: Deploy JAR /WEB-INF/lib/mail.jar to E:\work\BatchPrint\MultiReport\MultiReport\WEB-INF\lib\mail.jar WebappLoader[/MultiReport]: Deploy JAR /WEB-INF/lib/saaj.jar to E:\work\BatchPrint\MultiReport\MultiReport\WEB-INF\lib\saaj.jar WebappLoader[/MultiReport]: Deploy JAR /WEB-INF/lib/unittest.jar to E:\work\BatchPrint\MultiReport\MultiReport\WEB-INF\lib\unittest.jar WebappLoader[/MultiReport]: Deploy JAR /WEB-INF/lib/wsdl4j.jar to E:\work\BatchPrint\MultiReport\MultiReport\WEB-INF\lib\wsdl4j.jar WebappLoader[/MultiReport]: Reloading checks are enabled for this Context StandardManager[/MultiReport]: Seeding random number generator class java.security.SecureRandom StandardManager[/MultiReport]: Seeding of random number generator has been completed ContextConfig[/MultiReport]: Added certificates -> request attribute Valve StandardWrapper[/MultiReport:default]: Loading container servlet default StandardWrapper[/MultiReport:invoker]: Loading container servlet invoker HttpConnector[8083] Starting background thread eid:3.
