【问题描述】：
我在使用 Axon 框架的 Spring Boot 微服务项目中有两个模块。在定义为保留模型的核心项目的第一个模块中，我有两个类（用户和角色），其中用户类包含角色列表：
////// The User and Role classes are in the first module
@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {
private Integer id;
private String username;
private String password;
private String email;
private boolean enabled = false;
private boolean accountNonExpired = true;
private boolean credentialsNonExpired = true;
private boolean accountNonLocked = true;
private List<Role> roles;
}
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Role {
private Integer id;
private String name;
}
在第二个模块中，我在 POM 文件中添加了第一个模块的依赖项，以便访问 User 和 Role 类：
<dependency>
<groupId>com.main</groupId>
<artifactId>core</artifactId>
<version>0.0.1</version>
</dependency>
在第二个模块中，当我尝试创建用户对象时，它会出错并且不会将用户保存到事件存储并抱怨角色类，特别是角色列表。以下是第二个模块中的控制器类，它正在创建要发送到 Axon 的用户对象：
@RestController
@RequestMapping(path = \"/api/v1/registerUser\")
public class RegisterUserController {
private final CommandGateway commandGateway;
......
@PostMapping
public ResponseEntity<?> registerUser(@RequestBody User user)
{
Role role = new Role();
role.setId(1);
role.setName(\"Admin\");
List<Role> roles = new ArrayList<Role>();
roles.add(role);
....
user.setRole(roles);
RegisterUserCommand command = new RegisterUserCommand();
command.setId(id);
command.setUser(user);
commandGateway.sendAndWait(command); /// Send the user to Axon
....
}
重要的：当我尝试只使用一个模块并将用户和角色类、控制器和所有东西放在该模块中时，它没有问题。

-
我需要提一下，我在用户类中将
private List<Role> roles更改为private Role role，并且工作正常。但是在对象列表的情况下，它有问题。 -
你好@Pezhman！您能与我分享确切的错误和堆栈跟踪吗？这将帮助我查明问题。此外，您是否也在使用 Axon Server？
-
谢谢@Mitchell Herrijgers 的评论。是的，我通过使用 Docker 来使用 Axon 服务器。
-
不幸的是，我看不到有关错误的详细信息。但是，我注意到您使用的是 Java17 和 XStream，对吗？ Java 17 上的 XStream 有很多问题。您可以尝试使用早期的 Java 版本，还是使用
JacksonSerializer？ -
这是一个例外：
org.axonframework.commandhandling.CommandExecutionException: com.hawramgard.user.core.models.Role。我没有使用 XStream。 Java 版本是 17。好吧，我会尝试 Java 和 JacksonSerializer 的早期版本。
