<!-- If you need to report a security issue please visit https://github.com/apache/dubbo/security/policy --> - [ ] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate. ### Environment * Dubbo version: 2.7.13 * Operating System version: MacOS 12.1 * Java version: 11 ### Steps to reproduce this issue consumer code : ```java ReferenceConfig<GenericService> reference = new ReferenceConfig<>(); ApplicationConfig applicationConfig = new ApplicationConfig(); applicationConfig.setName("dubbo-provider"); RegistryConfig registryConfig = new RegistryConfig(); registryConfig.setAddress("zookeeper://127.0.1:2181"); reference.setApplication(applicationConfig); reference.setRegistry(registryConfig); reference.setProtocol("dubbo"); reference.setInterface("com.msnu.demo.provider.OrderService"); reference.setVersion("1.0.0"); reference.setTimeout(1000); reference.setGeneric("true"); GenericService genericService = reference.get(); Order order = new Order("20220110172900001", new BigDecimal(10000000.00)); String orderJson = objectMapper.writeValueAsString(order); // The price attribute type is Long in linkedHashMap LinkedHashMap linkedHashMap = objectMapper.readValue(orderJson, LinkedHashMap.class); Object result = genericService.$invoke( "queryOrder", new String[]{"com.msnu.demo.provider.OrderDto"}, new Object[]{linkedHashMap}); System.out.println(result); ``` provide code : ```java public class OrderServiceImpl implements OrderService{ @Override public OrderDto queryOrder(OrderDto orderDto) { System.out.println(orderDto); return orderDto; } } ``` Pls. provide [GitHub address] to reproduce this issue. ### Expected Behavior <!-- What do you expect from the above steps？--> result is {orderId=20220110172900001, price=10000000, class=com.msnu.demo.provider.OrderDto} ### Actual Behavior <!-- What actually happens? --> If there is an exception, please attach the exception trace: result is {orderId=20220110172900001, price=1.0E+7, class=com.msnu.demo.provider.OrderDto} The analysis is as follows： code: ```java org.apache.dubbo.common.utils.CompatibleTypeUtils#compatibleTypeConvert ``` line : 173 ```java if (type == BigDecimal.class) { return BigDecimal.valueOf(number.doubleValue()); } ``` If I use <b>new BigDecimal(number.doubleValue())</b>, can fix this problem -- This is an automated message from the Apache Git Service.
