手写mybatis xml版本

//1.解析mapperXml配置文件
        MapperBean mapperBean = XmlParseUtils.loadXml(path);
        if (!method.getDeclaringClass().getName().equals(mapperBean.getInterfaceName())) {
            return null;
        }
        //2.查找要执行的方法
        List<InterfaceMethodInfo> interfaceMethodInfoList = mapperBean.getInterfaceMethodInfoList();
        InterfaceMethodInfo currentMethodInfo = getInterfaceMethodInfo(method, interfaceMethodInfoList);
        if (currentMethodInfo == null) {
            return null;
        }
        //3.执行sql
        List<Object> paramsList = new ArrayList<>();
        paramsList.add(args[0]);
        ResultSet resultSet = JDBCUtils.query(currentMethodInfo.getSql(), paramsList);
        //4.结果赋值
        Object returnTypeObj = currentMethodInfo.getResultType();
        setReturnTypeObj(returnTypeObj, resultSet);
