[GitHub] [dubbo-go-hessian2] Euraxluo opened a new issue #262: 形如Page{List data;},T=UserVo, UserVo{User user;}的多层嵌套结构,在序列化时,UserVo被序列化为HashMap
Euraxluo opened a new issue #262:

<!-- Please use this template while reporting a bug and provide as much info as possible. Not doing so may result in your bug not being addressed in a timely manner. Thanks!
-->
**What happened**:
go-mod:
```
require (
github.com/apache/dubbo-go v1.5.5
github.com/apache/dubbo-go-hessian2 v1.8.2
github.com/dubbogo/gost v1.9.5
)
```
当我使用以上版本进行和java dubbo进行通信时,发现复杂嵌套对象的序列化会出错,会把List<UserVo>序列化为List<HashMap>,导致服务端代码运行失败
**What you expected to happen**:
错误的序列化,导致实体类中的某些方法无法被调用
**How to reproduce it (as minimally and precisely as possible)**:
server
```java
//interface
public interface UserProvider {
void collectionUser(Page<UserVo> pageUserVo);
}
//impl
public class UserProviderImpl implements UserProvider {
public void collectionUser(Page<UserVo> pageUserVo ){
List<UserVo> userVoList = pageUserVo.getData();
UserVo userVo = (UserVo) userVoList.toArray()[0];
return;
}
}
//pojo Page
public class Page<T> implements Serializable {
private static final long serialVersionUID = 1L;
private List<T> data;
public Page() {
}
public Page( List<T> data) {
this.data = data;
}
public List<T> getData() {
return this.data;
}
public void setData(List<T> data) {
this.data = data;
}
}
//pojo UserVo
public class UserVo implements Serializable {
private User user;
public UserVo(User user) { this.user = user; }
public UserVo() { }
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
}
```
client_main.go
```go
var (
appName = "UserProviderGer"
referenceConfig = config.ReferenceConfig{
Registry: "demoZk",
InterfaceName: "com.dml_express.dubbo_test.UserProvider",
Cluster: "failover",
Protocol: dubbo.DUBBO,
Generic: true,
}
)
func init() {
hessian.RegisterPOJO(&pkg.User{})
hessian.RegisterPOJO(&pkg.UserVo{})
hessian.RegisterPOJO(&pkg.UserVos{})
referenceConfig.GenericLoad(appName)
}
func main() {
collectionUser()
}
func collectionUser() {
genericService := referenceConfig.GetRPCService().(*config.GenericService)
page :=pkg.Page{
Data: []pkg.UserVo{
pkg.UserVo{
User: pkg.User{
Id: "1000",
Name: "user_name",
Age: 2,
Time: time.Now(),
},
},
pkg.UserVo{
User: pkg.User{
Id: "1000",
Name: "user_name",
Age: 2,
Time: time.Now(),
},
},
},
}
resp, err := genericService.Invoke(context.TODO(),
[]interface{}{"collectionUser",
[]string{"com.dml_express.dubbo_test.Page"},
[]interface{}{page}})
if err != nil {
gxlog.CError("error: %v\n", err)
os.Exit(1)
return
}
gxlog.CInfo("response result: %v\n", resp)
}
```
pkg.user.go
```go
type User struct {
Id string
Name string
Age int32
Time time.Time
}
func (User) JavaClassName() string {
return "com.dml_express.dubbo_test.User"
}
type UserVo struct{
User User
}
func (UserVo) JavaClassName() string {
return "com.dml_express.dubbo_test.UserVo"
}
type Page struct {
Data []UserVo `hessian:"data"`
}
func (Page) JavaClassName() string {
return "com.dml_express.dubbo_test.Page"
}
```
**Anything else we need to know?**:
当我调用时,会报以下错误在java端impl中
` error: java.lang.ClassCastException: java.util.HashMap cannot be cast to com.dml_express.dubbo_test.UserVo
`

@Euraxluo pls create a unit test for this issue， u can ref the following example:
eg:
- https://github.com/apache/dubbo-go-hessian2/blob/cbcfbc21675e5f81e31d1257f333e8b0c384d463/test_hessian/src/main/java/test/TestCustomReply.java#L524

You are advised to upgrade hessian. No problem is found when the latest version is used
