没有为org.hibernate.proxy.pojo.javassist.Javassist

Question

我正在处理SpringMVC，Hibernate＆，JSON但出现此错误。

HTTP Status 500 - Could not write JSON: No serializer found for class org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationConfig.SerializationFeature.FAIL_ON_EMPTY_BEANS) ) 

请在下面检查我的实体

    @Entity

@Table(name="USERS")

public class User {

    @Id

    @GeneratedValue

    @Column(name="USER_ID")

    private Integer userId;

    @Column(name="USER_FIRST_NAME")

    private String firstName;

    @Column(name="USER_LAST_NAME")

    private String lastName;

    @Column(name="USER_MIDDLE_NAME")

    private String middleName;

    @Column(name="USER_EMAIL_ID")

    private String emailId;

    @Column(name="USER_PHONE_NO")

    private Integer phoneNo;

    @Column(name="USER_PASSWORD")

    private String password;

    @Column(name="USER_CONF_PASSWORD")

    private String  confPassword;

    @Transient

    private String token;

    @Column(name="USER_CREATED_ON")

    private Date createdOn;

    @OneToMany(fetch=FetchType.EAGER,cascade=CascadeType.ALL)

    @Fetch(value = FetchMode.SUBSELECT)

    @JoinTable(name = "USER_ROLES", joinColumns = { @JoinColumn(name = "USER_ID") }, inverseJoinColumns = { @JoinColumn(name = "ROLE_ID") })

    private List<ActifioRoles> userRole = new ArrayList<ActifioRoles>();

    @OneToMany(fetch=FetchType.EAGER,cascade=CascadeType.ALL,mappedBy="userDetails")

    @Fetch(value = FetchMode.SUBSELECT)

    private List<com.actifio.domain.Address> userAddress = new ArrayList<com.actifio.domain.Address>();

    @OneToOne(cascade=CascadeType.ALL)

    private Tenant tenantDetails;

    public Integer getUserId() {

        return userId;

    }

    public void setUserId(Integer userId) {

        this.userId = userId;

    }

    public String getFirstName() {

        return firstName;

    }

    public void setFirstName(String firstName) {

        this.firstName = firstName;

    }

    public String getLastName() {

        return lastName;

    }

我该如何解决？
