在Scala2.11中运行时动态编译scala类文件

import scala.reflect.runtime.{currentMirror, universe}
import scala.tools.reflect.ToolBox

val toolbox = currentMirror.mkToolBox()

val code = """
  class DynamicClass {
    def hello(): Unit = {
      println("Hello, dynamic class!")
    }
  }
"""

4. 使用`ToolBox`对象编译Scala代码字符串并获取编译结果：
```scala
val tree = toolbox.parse(code)
val compiledCode = toolbox.compile(tree)

val dynamicClass = compiledCode().asInstanceOf[{ def hello(): Unit }]
dynamicClass.hello()
