示例1: getConstantValue
import scouter.javassist.bytecode.ConstPool; //导入方法依赖的package包/类
/**
* Returns the value of this field if it is a constant field.
* This method works only if the field type is a primitive type
* or <code>String</code> type. Otherwise, it returns <code>null</code>.
* A constant field is <code>static</code> and <code>final</code>.
*
* @return a <code>Integer</code>, <code>Long</code>, <code>Float</code>,
* <code>Double</code>, <code>Boolean</code>,
* or <code>String</code> object
* representing the constant value.
* <code>null</code> if it is not a constant field
* or if the field type is not a primitive type
* or <code>String</code>.
