Spring mvc 在thymeleaf中显示内部对象

我正在尝试在应用程序中显示我的用户角色

这是我的豆子

private Set<ClientRole> clientRoles = new HashSet<>();

}

这里是角色实体。Bean正在尝试访问这些角色 百里香。因为我正在使用thymeleaf extras spring security 4。我会的 像管理员一样，用户可以修改角色。我希望能够 显示和修改。其他字段正确显示，但 clientRolse给了我一根长长的绳子。 com.zenopoint.domain.Client.clientRoles

@Entity
public class Role {
@Id
private int roleId;
private String name;

@OneToMany(mappedBy = "role", cascade = CascadeType.ALL, fetch = 
 FetchType.LAZY)
private Set<ClientRole> clientRoles = new HashSet<>();

public Role() {

}

public int getRoleId() {
    return roleId;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public Set<ClientRole> getClientRoles() {
    return clientRoles;
}

public void setClientRoles(Set<ClientRole> clientRoles) {
    this.clientRoles = clientRoles;
}

public void setRoleId(int roleId) {
    this.roleId = roleId;
}

@实体
公共阶级角色{

私人内部控制；
私有字符串名称；
@OneToMany（mappedBy=“role”，cascade=CascadeType.ALL，fetch=
FetchType.LAZY）
private Set clientRoles=new HashSet（）；
公共角色（）{

public int getRoleId（）{
返回roleId；

公共字符串getName（）{

}
public void setClientRoles（Set clientRoles）{

}
公共void setRoleId（int-roleId）{

}

}

这是我的控制器

@RequestMapping("/accounts")
 public String accounts(Model model) {
    List<Client> clientsList = userservice.findUserList();
    model.addAttribute("clientsList", clientsList);
    return "app/accounts";
}

@RequestMapping（“/accounts”）
公共字符串帐户（模型）{
List clientsList=userservice.findUserList（）；
addAttribute（“clientsList”，clientsList）；
返回“应用程序/帐户”；
