Hi everyone:
The version of Spring & Spring Boot in ServiceComb java chassis are
4.3.5.RELEASE and 1.4.5.RELEASE, seems a little behind, we may upgrade them.
Spring Boot and Spring Version correlation :
Spring Boot Version Spring Version
1.5.8.RELEASE 4.3.12.RELEASE
1.5.9.RELEASE 4.3.13.RELEASE
1.5.10.RELEASE 4.3.14.RELEASE
1.5.11.RELEASE 4.3.15.RELEASE
1.5.12.RELEASE 4.3.16.RELEASE
I found if consumer use the RestTemplate make a invocation to our producer
and producer throw an unhande exception, http code with 590 [Cse Internal
Server Error] will be return to consumer side, but the Behavior of RestTemplate
getForObject or postForObject in different version of Spring is also not the
same, for example:
```java
String result =
restTemplate.getForObject("http://127.0.0.1:8080/springmvc/controller/sayhi?name=throwexception",String.class);
```
* In 4.3.12.RELEASE still throw UnknownHttpStatusCodeException, same as
current (4.3.5.RELEASE) ;
* In 4.3.13.RELEASE and 4.3.14.RELEASE change to throw
org.springframework.web.client.ResourceAccessException ;
* In 4.3.15.RELEASE and 4.3.16.RELEASE won't throw any Exception and direct
return {"message":"Cse Internal Server Error"} .
So if we update the Spring version to 4.3.12.RELEASE above,user may get into
trouble when upgrade 1.0.0-m2, but 4.3.16.RELEASE had fix some bugs and may
better in security.
Any other ideas or suggestions are welcome !
