任何人都可以帮我找出tomcat中的错误原因.我正在使用solr.开始工作正常.稍后我会提出这个错误.重新启动后它工作正常.请帮我找出错误.

任何人都可以通过Thread和ThreadPool的例子来指导我们它们之间的区别是什么？哪个最好用...？它的缺点是什么？
$near和之间有什么区别$within？
db.geodata.find({ "loc" : { "$within" : { "$center" : [ [ 12.91365 , 77.59395] , 4]}}}).limit(10);
db.geodata.find({ "loc" : { "$near" : [ 12.91365 , 77.59395] , "$maxDistance" : 4}}).limit(10);
谁能详细解释一下？
我是solrnet的新手.我需要将此URL传递给我的"pharmaSearch"requestHandler,我需要获取结果xml.指导如何在solrNet中执行此操作(现在为url工作在brower中)我还需要在.net应用程序中调用它
提前谢谢.
我需要知道java中的线程数组.这是C#中线程数组的代码
Thread[] TCreate = new Thread[iThreadSize];
for (int i = 0; i < TCreate.Length; i++)
{
TCreate[i] = new Thread(delegate()
{
lst.Add(this.getResult(url));
});
TCreate[i].Name = "URL"+i;
TCreate[i].Start();
}
for(int j=0;j<TCreate.Length;j++)
while (TCreate[j].IsAlive)
Thread.Sleep(10);
我需要知道在java中这样做.
MyTestClass qryCompoents=new MyTestClass();
for(int i=0;i<ThreadSize;i++)
{
switch(obj.getQueryLevelValue(i)) //Decide according to level
{
case 1:
qryCompoents.prepareAndProcess_I(obj.getQueryString(i),obj,i);
break;
case 2:
qryCompoents.prepareAndProcess_II(obj.getQueryString(i),obj,i);
break;
}
}
如果您需要任何细节,请告诉我.
如果我转换这个
Thread[] TCreate = new Thread[numExpression];
for(int i=0;i<numExpression;i++)
{
TCreate[i] = new Thread(new Runnable() {
public void run() {
switch(obj.getQueryLevelValue(i)) //Decide according to …有没有办法获取 AWS s3 存储桶的已删除历史记录？
问题陈述： 一些 s3 文件夹被删除。有没有办法知道什么时候被删除
我需要知道EmbeddedSolrServer和CommonsHttpSolrServer之间的性能.
EmbeddedSolrServer:
File home = new File("C:\\workspace\\SolrWithMultipleCore\\solr");
File f = new File( home, "solr.xml" );
CoreContainer container = new CoreContainer();
container.load( "C:\\workspace\\SolrMultipleCore\\solr", f );
EmbeddedSolrServer server = new EmbeddedSolrServer( container,"core1");
EmbeddedSolrServer server1 = new EmbeddedSolrServer( container,"core2");
String query=params.getParams("q");
String query1=params.getParams("q1");
SolrQuery solrquery=new SolrQuery(query);
QueryResponse rsp1 = server.query(solrquery);
QueryResponse rsp2 = server1.query(solrquery);
CommonsHttpSolrServer:
SolrServer httpServer = new CommonsHttpSolrServer(url);
QueryResponse rsp1=httpServer.query(q);
SolrServer httpServer1 = new CommonsHttpSolrServer(url1);
QueryResponse rsp2=httpServer1.query(q1);
哪个是最好的EmbeddedSolrServer或CommonsHttpSolrServer？我所说的两个核心有不同的架构.我需要知道什么是MultiThreadedHttpConnectionManager.
