Red5應用程序調試

Question

我試圖將我的red5應用程序部署到webapps文件夾。但！我的輸出中有一些錯誤。

Exception in thread "Launcher:/myApp" org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'web.context' defined in ServletContext resource [/WEB-INF/red5-web.xml]: Unsatisfied dependency expressed through bean property 'clientRegistry': : Cannot find class [org.red5.core.Application] for bean with name 'web.handler' defined in ServletContext resource [/WEB-INF/red5-web.xml]; nested exception is java.lang.ClassNotFoundException: org.red5.core.Application; nested exception is org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [org.red5.core.Application] for bean with name 'web.handler' defined in ServletContext resource [/WEB-INF/red5-web.xml]; nested exception is java.lang.ClassNotFoundException: org.red5.core.Application

畢竟，我有我的應用程序文件夾在webapps，但沒有在我的項目類文件夾中的.class文件。所以，我不能在我的客戶端應用程序中使用服務器端應用程序。 有什麼問題？

應用程序是默認生成的。這裏是我的RED5-web.xml中

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"> 
<beans> 

    <!-- 
    Defines a properties file for dereferencing variables 
    --> 
    <bean id="placeholderConfig" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> 
     <property name="location" value="/WEB-INF/red5-web.properties" /> 
    </bean> 

    <!-- 
    Defines the web context 
    --> 
    <bean id="web.context" class="org.red5.server.Context" 
     autowire="byType" /> 

    <!-- 
    Defines the web scopes 
    --> 
    <bean id="web.scope" class="org.red5.server.WebScope" 
     init-method="register"> 
     <property name="server" ref="red5.server" /> 
     <property name="parent" ref="global.scope" /> 
     <property name="context" ref="web.context" /> 
     <property name="handler" ref="web.handler" /> 
     <property name="contextPath" value="${webapp.contextPath}" /> 
     <property name="virtualHosts" value="${webapp.virtualHosts}" /> 
    </bean> 

    <!-- 
    Defines the web handler which acts as an applications endpoint 
    --> 
    <bean id="web.handler" 
     class="org.red5.core.Application" 
     singleton="true" /> 

</beans> 

而我的應用程序類

import org.red5.server.api.IConnection; 
import org.red5.server.api.IScope; 
import org.red5.server.api.service.ServiceUtils;

public class Application extends ApplicationAdapter { 

    /** {@inheritDoc} */ 
    @Override 
    public boolean connect(IConnection conn, IScope scope, Object[] params) { 
     return true;

    /** {@inheritDoc} */ 
    @Override 
    public void disconnect(IConnection conn, IScope scope) { 
     super.disconnect(conn, scope); 
    } 

} 

我做這一切在Eclipse中的Red5插件。所以...我不知道什麼可能是錯的。

Answer 1

我有完全相同的問題。聽起來就像你試圖僅使用新的Red5_1.0來跟隨教程視頻，就像我一樣。經過多日，啤酒和瘀傷將我的頭撞向我的辦公桌，我發現如果您在red5-web.xml文件中將您的班級更改爲「org.red5.server.scope.WebScope」，它應該可以正常工作（bean ID = 「web.scope」）。另外，您可能需要從「import org.red5.server.api.IScope;」更改您的org.red5.core源導入。到「import org.red5.server.api.scope.IScope;」。顯然，在Red5的新版本中出現了一些類重構

Answer 2

雖然當我檢查我的類已經設置爲第九版中提到的「org.red5.server.scope.WebScope」時，我收到了類似的錯誤馬特的回答。後來我發現我缺少webaps/chat/WEB-INF /下的lib目錄。

如果其他人有類似的問題，這可能會有用。
