Question

Tomcat'i ubuntu paket yöneticisine yükledim. Günlüğü açarım ve gördüğüm ilk şey ilginç bir istisna.

java.lang.NoClassDefFoundError: org/Spring Framework/asm/ClassVisitor

ben kurulumda şey eksik ?

En başta yeniden başladığımın sebebinin Tomcat'i kullanarak webservices'te ilk defa verdiğim ve bunun işe yaramadığı söylendi. Ama şimdilik: Neden bu özel durumu alıyorum? Ben iyilik dışarı günlüğün tamamını yapıştırılan:

Answer 1

. Web uygulamanızın hangi sürümünü kullandığınızdan emin değilim, ancak bu JAR dosyası için en son sürüm (bugün itibariyle) 3.1.0.RELEASE. Maven kullanıyorsanız

, projenizin pom.xml bu ekleyerek projenize eksik JAR dosyasını ekleyebilirsiniz:

<dependency> 
    <groupId>org.springframework</groupId> 
    <artifactId>org.springframework.asm</artifactId> 
    <version>3.1.0.RELEASE</version> 
</dependency> 

Eğer bağımlılıkları yönetmek için Maven kullanmıyorsanız, daha sonra tüm Bahar Çerçevesi'ni http://www.springsource.org/spring-community-download'dan yükleyerek org.springframework.asm-3.1.0.RELEASE.jar (veya ihtiyacınız olan herhangi bir sürümü) edinebilirsiniz. ASM jar dosyası daha sonra projenizin WEB-INF/lib klasörüne yerleştirilmelidir.

Answer 2

yaygın yaklaşım bu durumu

1) eksik belgeli içerdiği kavanoz kütüphane kurmak işlemek için.

2) Bu kavanozun sizin sınıf yolunda sunduğu, kontrol

Tomcat Bahar ASM dayanan bir web uygulamasını dağıtmak için çalışıyor ama üzerinde sınıf Bahar ASM JAR dosyasını bulamıyor gibi görünüyor

Answer 3

Bu hata, muhtemelen web.xml dosyasındaki girdilerden gelir. Örneğin, buna sahipseniz - org.springframework.web.servlet.DispatcherServlet. !! erkek kedi başladığında Yani, yük-on-başlatma yayı asm bağlamı öğrenmek etmeye çalışır, ancak (kavanoz kullanılabilir olsa da) muhtemelen maven bağımlılık kavanozu eksik dağıtım assemblyis bu kadar aşağıda

**Basiaclly In project options you should include Maven Dependencies to your Deployment Assembly** 

1. Project properties-> Deployment Assembly -> Add.. 

2. Java Build Path Entries -> Maven Dependencies 

3. Finish 

Run mavem clean install and run on server. The error should go away. 

Answer 4

ayarlamayı deneyin gidermek için Benim durumumda, sorun bilgisayarda yüklü olan Java'nın 2 sürümündeydi: Java 7 ve Java 8. Unisntalling Java 7 sorunu çözüldü.
