的ClassNotFoundException開始春季啓動應用程序

Question

我得到ClassNotFoundException的異常，當我與Maven打包我的代碼，然後用啓動時：

java -jar target\factorify-1.0-SNAPSHOT.jar 

我可以看到，在我的「胖罐子」是文件夾的lib具有所有依賴性我可以手動找到拋出ClassNotFoundException的類。

清單：

Manifest-Version: 1.0 
    Archiver-Version: Plexus Archiver 
    Built-By: Jakub 
    Start-Class: me.factorify.server.Application 
    Spring-Boot-Version: 1.2.0.RELEASE 
    Created-By: Apache Maven 3.1.1 
    Build-Jdk: 1.8.0_25 
    Main-Class: org.springframework.boot.loader.JarLauncher 

的pom.xml：

<packaging>jar</packaging>

    <spring.boot.version>1.2.0.RELEASE</spring.boot.version>

</properties>

    <groupId>org.springframework.boot</groupId> 
    <artifactId>spring-boot-starter-parent</artifactId>

     ... 
     <plugin> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-maven-plugin</artifactId> 
      <version>${spring.boot.version}</version> 
      <executions> 
       <execution> 
        <goals> 
         <goal>repackage</goal> 
        </goals> 
       </execution> 
      </executions> 
     </plugin> 

當我從我的IDE中運行的類，但它拋出ClassNotFoundException的，當我從命令行中運行它，它的工作原理。

任何想法可能導致此？

感謝

EDIT 2

我可以看到在日誌文件中該行與廣口瓶（activejdbc-1.4 .10-SNAPSHOT.jar）與org.javalite.activejdbc.Model在那裏。 JarLauncher必須以某種方式無法加載它。

Answer 1

我發現了這個問題。問題出在番石榴反射。我用它來查找所有實體，但是classInfo.load（）爲「胖罐子」拋出NoClassDefFoundError。

我定這樣的：（見新行，原線）

public static Set<Class<? extends Model>> getAllEntities() throws ClassNotFoundException { 

    Set<Class<? extends Model>> allEntities = new HashSet<>(); 
    Set<ClassPath.ClassInfo> classes; 
    try { 
     classes = ClassPath.from(Application.class.getClassLoader()).getTopLevelClassesRecursive("me.factorify.server"); 
    } catch (IOException e) { 
     throw new RuntimeException(e); 
    } 
    for(ClassPath.ClassInfo classInfo : classes) { 
     // NEW LINE 
     Class<?> clazz = Application.class.getClassLoader().loadClass(classInfo.getName()); 

     //ORIGINAL LINE Class<?> clazz = classInfo.load(); 

     if (Model.class.isAssignableFrom(clazz)){ 
      allEntities.add((Class<? extends Model>) clazz); 
     } 
    } 
    return allEntities; 
}
