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.

                        switch (m.get("操作").toString()) {
                            case "启动应用":
                                builder.append("        BOperate.open();
");
                                break;
                            case "点击":
                                builder.append("        BOperate.click("" + replaceQuotation(m.get("Xpath").toString().trim()) + "",true);

【解决】

引用处：

                        //sonar问题:Reduce the number of switch cases from 38 to at most 30.
                        // 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
                        String operationStr = m.get("操作").toString();
                        String builderAppendStr = Operation.NULL.getInstance(operationStr).builderAppendStr();
                        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

public enum Operation {
        NULL("") {
            @Override
            public String builderAppendStr() {
                return null;
            }
        },
        OPEN("启动应用") {
            @Override
            public String builderAppendStr() {
                return "        BOperate.open();
";
            }
        },
        CLICK("点击") {
            @Override
            public String builderAppendStr() {
                return "        BOperate.click("" + replaceQuotation(sTCConvertMap.get("Xpath").toString().trim()) + "",true);
";
            }
        },
        TYPE("输入") {
            @Override
            public String builderAppendStr() {
                return "        BOperate.type("" + replaceQuotation(sTCConvertMap.get("Xpath").toString().trim()) + ""," + paramStr(sTCConvertMap.get("参数1")) + ");
";
            }
        },
        GET_TEXT("获取文本") {
            @Override
            public String builderAppendStr() {
                return "        " + valStr(paramStr(sTCConvertMap.get("参数1"))) + " = BOperate.getText("" + replaceQuotation(sTCConvertMap.get("Xpath").toString().trim()) + "",true);
";
            }
        }

        ;


        Operation(String operationName) {
            this.operationName = operationName;
        }

        private String operationName;

        public String getOperationName() {
            return operationName;
        }

        public Operation getInstance(String operationName) {
            for (Operation operation : Operation.values()) {
                if (operationName.equals(operation.getOperationName())) {
                    return operation;
                }
            }
            return Operation.NULL;
        }

        public abstract String builderAppendStr();
    }
