用枚举类解决Switch-Case过长的sonar问题Reduce the number of switch cases from 38 to at most 30.

【问题】Switch-Case过长的sonar问题Reduce the number of switch cases from 38 to at most 30.

 1                         switch (m.get("操作").toString()) {
 2                             case "启动应用":
 3                                 builder.append("        BOperate.open();
");

【解决】

引用处：

1                         //sonar问题:Reduce the number of switch cases from 38 to at most 30.
2                         // 解决方法：操作的关键字存到枚举类。遍历枚举类，对应的枚举类方法做操作处理
3                         String operationStr = m.get("操作").toString();
4                         String builderAppendStr = Operation.NULL.getInstance(operationStr).builderAppendStr();
5                         builder.append(builderAppendStr);

添加的枚举类（做后续扩展）：其中的变量在原代码引用处保存到静态变量，在枚举类调用

 1 public enum Operation {
 2         NULL("") {
 3             @Override
