解决方案 »

  1.   

    错误很清晰
    Caused by: java.lang.ClassNotFoundException: org.hyperic.sigar.SigarException
      

  2.   

    <dependency>
      <groupId>org.hyperic</groupId>
      <artifactId>sigar</artifactId>
      <version>1.6.4</version>
      </dependency>
      </dependencies>
      
      

  3.   

    <dependency>
      <groupId>org.hyperic</groupId>
      <artifactId>sigar</artifactId>
      <version>1.6.4</version>
      </dependency>
      </dependencies>
    有jar包的
      
      

  4.   

    <dependency>
      <groupId>org.hyperic</groupId>
      <artifactId>sigar</artifactId>
      <version>1.6.4</version>
      </dependency>
      </dependencies>
    有jar包的
      
    有依赖不代表不会抛这个异常
    你要确认的是为啥  org.hyperic.sigar.SigarException 这个类不存在
    实际上提示异常类找不到,一般都是出现了异常,然后new这个异常报错了所以解决这个问题有两个方向,一是找出org.hyperic.sigar.SigarException 这个类不存在的原因,这个可能原因就复杂了,你得自己慢慢判断
    二是看源码,解决掉抛出SigarException异常的原因,如果流程正确,就算SigarException 不存在,也不会触发类加载操作,自然也不会Class not found了
      

  5.   

    你的工程是不是maven分多个module引用的。编译没问题。运行有问题。有可能是你引用的其他模块的jar没有更新。从新mvn clean 然后打包一下看看。从最底一级开始打包。比如 controller引用service，service引用dao，那就先从dao开始。
      

  6.   

    ClassNotFoundException异常一般都是类没有找到，可以检查是否存在jar包冲突问题导致的
      

  7.   

    没找到类，pom写上依赖不代表能下到，下载后不代表有这个类
