GitHub user mysterin created a discussion: dubbo3.2.18 Anti-sequencing turns
Timestamp into a LocalDateTime type
### Pre-check
- [X] I am sure that all the content I provide is in English.
### Apache Dubbo Component
Java SDK (apache/dubbo)
### Details
Both the client and server dubbo versions are 3.2.18, and neither shows the
configuration serialization protocol
Service interface definition： `public RpcResult<Date>
businessMaxAuthTime(Caller caller, UserBusinessAuthRequest request)`
The client call will error： `java.lang.ClassCastException:
java.time.LocalDateTime cannot be cast to java.util.Date`
By arthas monitoring call status
Service server returns：
```
@RpcResult[
code=@RpcCode[
Success=@RpcCode[RpcCode{code=0, msg='成功'}],
Error=@RpcCode[RpcCode{code=-1, msg='失败'}],
code=@Integer[0],
msg=@String[成功],
$VALUES=@RpcCode[][isEmpty=false;size=16],
name=@String[Success],
ordinal=@Integer[0],
],
msg=@String[成功],
data=@Timestamp[2021-11-04 13:48:57,000],
]
```
The result received by the client：
```
@RpcResult[
code=@RpcCode[
Success=@RpcCode[RpcCode{code=0, msg='成功'}],
Error=@RpcCode[RpcCode{code=-1, msg='失败'}],
code=@Integer[0],
msg=@String[成功],
$VALUES=@RpcCode[][isEmpty=false;size=16],
name=@String[Success],
ordinal=@Integer[0],
],
msg=@String[成功],
data=@LocalDateTime[
MIN=@LocalDateTime[-999999999-01-01T00:00],
MAX=@LocalDateTime[+999999999-12-31T23:59:59.999999999],
serialVersionUID=@Long[6207766400415563566],
date=@LocalDate[2021-11-04],
time=@LocalTime[13:48:57],
],
]
```
As you can see, the data type has changed from Timestamp to LocalDateTime, but
if you downgrade the client's dubbo version to 3.0.12, then the return type
received by the client is Timestamp, which is normal.
My question is whether dubbo3.2.18 has made any changes to anti-sequencing that
caused the type conversion issue? How can I fix it in version 3.2.18?
