現(xiàn)在有一個要求,每秒有1W條UDP的數(shù)據(jù)要更新（數(shù)據(jù)量不大） 是應(yīng)該用redis 還是其他軟件？
目前我自己測試 , redis單例或集群 + jedisPool 都只能處理6K的數(shù)據(jù)量 ,請問有沒有更合適數(shù)據(jù)頻繁寫入的軟件或架構(gòu)？

問題是這樣的
我想把下面的book對像（含F(xiàn)actory屬性）使用緩存ehcache緩存起來,但是總是報錯,相信是我的使用方式不對,或是此路不通吧,有沒有什么好的辦法可以實現(xiàn)這樣的想法呢,多謝了
public class Factory { private String Address; public Factory(String address) { super(); Address = address; } public String getAddress() { return Address; } public void setAddress(String address) { Address = address; } }

public class Book implements Serializable { private String bookName; private Factory factory; public Factory getFactory() { return factory; } public void setFactory(Factory factory) { this.factory = factory; } public Book(String bookName) { this.bookName = bookName; } public String getBookName() { return bookName; } }
Ehcache使用方法
CacheManager manager1 = new CacheManager(); String[] cacheNamesForManager1 = manager1.getCacheNames(); Cache cache = manager1.getCache("sampleCache1"); Book b = new Book("Music Book"); b.setFactory(new Factory("china")); Element element1 = new Element("book", b); cache.put(element1);

在使用spring aop+ehcache作為系統(tǒng)緩存,無法正常啟動,,
如果去掉methodCachePointCut攔截器那么能夠正常啟動,
配置文件如下:

4、注解使用ehcache @Mapper public interface ProductMapper { int deleteByPrimaryKey(String id); int insert(Product record); int insertSelective(Product record); Product selectByPrimaryKey(String id); int updateByPrimaryKeySelective(Product record); int updateByPrimaryKey(Product record); @Select("SELECT * FROM PRODUCT") @Cacheable(value = Fields.SYS_CACHE,key = "test") List findAll(); }

HDC調(diào)試需求開發(fā)（15萬預(yù)算）,能者速來！>>>
我使用jboot+shiro部署了一個程序,ehcache.xml中設(shè)置了cacheName為myCache的緩存：
jboot啟動項里面也添加了ehcache插件,指定地址為class目錄下ehcache.xml
然后使用CacheKit.put加入緩存
加入緩存的時候日志打印warn:
Could not find cache config [myCache], using default.
然后這個緩存只能持續(xù)一分鐘的樣子,一分鐘以后就沒有緩存了。
我覺得應(yīng)該是沒有關(guān)聯(lián)到ehcache.xml文件或者jar有沖突,因為shiro里面加了shiro-ehcache包
pom.xml如下

io.jboot
jboot
1.4.0


com.xiaoleilu
hutool-all
3.2.0





org.apache.shiro
shiro-ehcache

HDC調(diào)試需求開發(fā)（15萬預(yù)算）,能者速來！>>>
在進行SOA項目開發(fā)時,我們使用了maven + dubbo + jetty的架構(gòu),在這里我遇到了這樣一個問題：
因為是SOA架構(gòu),所以我們創(chuàng)建了多個dubbo 每個dubbo是一個獨立的項目工程,且開發(fā)后期我們會在多個環(huán)境部署和調(diào)試；這樣問題就來了,我們配置了多個profile 這樣在mvn clean package -P profileId時沒有問題,但是在jetty:run -P profileId 時總是不使用指定的prifileId ;很是不解,坐等大神回復(fù)?。。。。。。。。。。。。。。?！

@CrawlScript 你好,想跟你請教個問題：
我將自動探測URL的代碼復(fù)制下來不能運行,報No default constructor found的錯誤

靜態(tài)資源位于src/main/resources/static目錄下面,主要存放JS、CSS、模板文件。未添加攔截器之前,訪問頁面時可以正常通過http://localhost/js/XXX.js這樣的方式加載js文件。但是按照如下代碼的方式添加攔截器后（攔截路徑“/personnal/**”）,不能通過http://localhost/js/XXX.js這樣的方式加載js文件。而控制臺顯示No mapping for GET /js/XXX.js。web容器用的是jetty @Configuration public class InterceptorConfig extends WebMvcConfigurationSupport { @Autowired private PowerInterceptor powerInterceptor; @Override public void addViewControllers(ViewControllerRegistry registry) { super.addViewControllers(registry); } @Override public void addInterceptors(InterceptorRegistry registry) { super.addInterceptors(registry); registry.addInterceptor(powerInterceptor).addPathPatterns("/personnal/**"); } }

最近公司的spring項目要是用websocket進行推送,我根據(jù)找來的文檔寫完demo后使用Tomcat啟動,當(dāng)時是啟動成功并測試通過。結(jié)果,公司的項目要使用jetty啟動,而我使用jetty9.4的版本啟動后總是出現(xiàn)各種異常。
上面是我使用的jar包和啟動時的異常,spring的版本也為4.2.5.RELEASE。
后來我根據(jù)錯誤添加了以下jar包
項目可以正常啟動,但建立連接就會拋出異常
請問jetty該如何啟動websocket,昨天已經(jīng)試過各種方法,導(dǎo)入各種有提到的jar包,但他們大多都是Tomcat啟動,效果都不理想,希望有大神能給些指點,謝謝。

我在IntelliJ 搭建jfinal + maven環(huán)境,依賴如下：
junit junit 4.8.2 test javax.servlet javax.servlet-api 3.0.1 javax.servlet.jsp jsp-api 2.1 javax.servlet.jsp.jstl javax.servlet.jsp.jstl-api 1.2.1 org.eclipse.jetty.orbit org.apache.taglibs.standard.glassfish 1.2.0.v201112081803 com.jfinal jfinal 2.2 com.jfinal jetty-server 8.1.8 org.eclipse.jetty jetty-maven-plugin 9.3.10.v20160621 8080 9966 stop 5 / org.apache.maven.plugins maven-compiler-plugin 2.3.2 1.7 1.7 UTF-8 org.apache.maven.plugins maven-resources-plugin 2.4 UTF-8

啟動類：

package com.ef.demo.common; import com.jfinal.core.JFinal; public class Stratup { public static void main(String[] args) { JFinal.start("src/main/webapp", 8080, "/", 5); } }

Controller：

public class IndexController extends Controller { public void index(){ // renderText("hello JFinal world!");//正常 renderJsp("index.jsp");//報錯： JSP support not configured } }

以上配置啟動正常但是訪問jsp頁面會報錯： JSP support not configured
我有2個問題：

1. 如何配置在開發(fā)環(huán)境（IntelliJ IDEA）maven+jetty＋jsp(我已經(jīng)嘗試把官demo的jar的依賴都加進去了但還是不能renderJSP )的依賴?
2. pom.xml 里面 jetty server的依賴的groupid用com.jfinal和用org.eclipse.jetty區(qū)別是什么？(如果把jfinal的jettey改成相同版本的eclipse的jetty則啟動報錯： Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/jetty/webapp/WebAppContext )

最近遇到一個奇怪的問題。
在SQLite的一個數(shù)據(jù)表中,START和FINISH兩個字段都是INTEGER類型,而且這兩個字段都創(chuàng)建了索引,ASC排序。之前一直都是正常的,今天出現(xiàn)下面的情況。
問題1：圖中查詢結(jié)果的START第一個值1586693177很明顯比查詢條件1587052800小,竟然也能查詢出來；
問題2：如果把圖中的查詢語句FINISH條件放出來,則無法查詢出任何記錄,事實上庫表中有符合條件的數(shù)據(jù)；
問題3：如果把START和FINISH兩個字段的索引刪除,再執(zhí)行上述查詢,則一切正常。
實在搞不懂什么情況了,希望有熟悉SQLite的大佬指點,提前謝過。
