接着上节的demo来看如何在Eclipse下搭建Openi的开发及调试环境.
一.下载openi-1.3.0-RELEASE-src
a.官方网站:或/index.html
b.下载源代码版本:/project/showfiles.php?group_id=142873
二.新建web project
在MyEclipse下新建web project:openi
1.openi-1.3.0-RELEASE-src\openi\src下的文件copy到上面新建的openisrc下.
2.openi-1.3.0-RELEASE\openi\openi.war,在tomcat解压后的文件夹下,将除WEB-INF之外的所有文件copy至刚才新建的项目
3.在MyEclipse下发布openi
4.当然，别忘了把openi-1.3.0-RELEASE\openi\openi-projects.war，openi-1.3.0-RELEASE\openi\mondrian.war拷贝到<tomcat_home>\webapps
5.查看，并设置断点进行调试
启动tomcat,http://localhost:8080/openi,应该可以访问了.用户密码如果没有修改的话,应该就是tomcat/tomcat,如果不对,请去<tomcat_home>\conf\tomcat-users.xml自己去找.
三、修改端口
该项目默认的端口是8080.而大多数tomcat可能设置成别的端口如8088等。在这里通过查看源代码，及在MyEclipse下面调试源代码，就可以发现，org.openi.project.ProjectFactory类中方法：getProject
publicstaticProjectgetProject(StringbaseDirName,StringprojectId)
throwsIOException{
//importanttogiveproperfeedbacktocaller
if(baseDirName==null){
thrownewIOException(
"Projectdirectorynameisnull.Thisshouldbethelocationforallprojects");
}
BeanStoragestorage=newBeanStorage();
StringprojectFilePath=newFile(baseDirName,
projectId+"/project.xml").getCanonicalPath();
logger.debug("Tryingtorestoreproject:"+projectFilePath);
ProjectretProject=null;
try{
retProject=(Project)storage.restoreBeanFromFile(projectFilePath);
}catch(Exceptione){
logger.debug("troublerestoringprojectfrom"+projectFilePath,e);
logger.debug("possiblyoldformat,tryingxslt");
}
if(retProject==null){
StringxsltPath=newFile(baseDirName).getParent()
+"/openi/WEB-INF/project/project.xsl";
logger.debug(
"transformingproject.xmlintonewformatusingtemplate"
+xsltPath);
try{
Stringbackup=backupOldFile(projectFilePath);
transformProjectToNewFormat(backup,projectFilePath,xsltPath);
//transformed,trytorestoreagain,thistimeifitdoesn'twork,throwIOException:
retProject=(Project)storage.restoreBeanFromFile(projectFilePath);
}catch(Exceptionex){
//logger.error(ex.getStackTrace());
thrownewIOException(
"Anerroroccuredwhiletransformingproject.xmlintonewformat\nrootcause:"
+ex.getMessage());
}
}
returnretProject;
}
从中可以看出project的datasource的来源.它来自文件：<tomcat_home>\webapps\openi-projects\foodmart\project.xml
在此文件中
<dataSourceMap>
<entry>
<string>mondrian</string>
<org.openi.analysis.Datasource>
<server>http://localhost:8080/mondrian/xmla</server>
<xmlaDatasource>MondrianFoodMart</xmlaDatasource>
<catalog>FoodMart</catalog>
</org.openi.analysis.Datasource>
</entry>
只需要把这里面的8080改成自己的端口就OK了。(当然,别忘了修改tomcat\confserver.xml中的端口了哦,呵呵).
请对openi或BI感兴趣的朋友多多支持,让俺认真研究研究,以便发更多的文件.下节写写对整个openi的设计.
