我正在我的应用程序中构建一个Ebean服务器。这是代码：
public Result refreshDataFromProduction() {
if (hasCorrectAccess(RoleType.BAMANAGER) != true && hasCorrectAccess(RoleType.SEMANAGER) != true
&& hasCorrectAccess(RoleType.ADMIN) != true) {
return ACCESS_DENIED;
} else {
// Get the eEbean server...
// Get the application.conf...
String serverEnvironment = "test";
String getValue = "";
Configuration appConfig = Configuration.root();
DataSourceConfig dataconfig = new DataSourceConfig();
getValue = Messages.get("db." + serverEnvironment + ".url");
dataconfig.setUrl(getValue);
getValue = Messages.get("db." + serverEnvironment + ".driver");
dataconfig.setDriver(getValue);
getValue = Messages.get("db." + serverEnvironment + ".username");
dataconfig.setUsername(getValue);
getValue = Messages.get("db." + serverEnvironment + ".password");
dataconfig.setPassword(getValue);
// Create the server config...
ServerConfig c = new ServerConfig();
c.setName(serverEnvironment);
c.setDdlGenerate(false);
c.setDdlRun(false);
c.setDefaultServer(true);
c.setRegister(true);
c.setDataSourceConfig(dataconfig);
// Add all Models here...
c.addClass(User.class);
EbeanServer server = EbeanServerFactory.create(c);
server.save(server);
return ok(genericsuccess.render());
}
}
此行发生错误：
EbeanServer server = EbeanServerFactory.create(c);
以下是完整错误：

我发现了一些帖子，但那些似乎没有帮助我：
Error reading annotations play framework 2.2
How solve error reading annotations in play framework 2
以下是我正在使用的课程：
@Entity
public class User extends Model {
@Id
public Long id;
@Constraints.Required
@Formats.NonEmpty
@Column(unique = true)
private String email;
@Constraints.Required
@Formats.NonEmpty
@Column(unique = true)
public String fullname;
@OneToMany(cascade = CascadeType.ALL)
public List<LinkedAccount> linkedAccounts;
...
}
@Entity
public class LinkedAccount extends AppModel {
private static final long serialVersionUID = 1L;
@Id
public Long id;
@ManyToOne
@JoinColumn(name = "user", insertable = false, updatable = false)
public User user;
public String providerUserId;
public String providerKey;
public Long userId;
public String email;
...
}
我猜它与@OneToMany和@ManyToOne引用有关，但不确定如何纠正。
