问题描述

我最近更新到 spring sts 4 所以我不确定是否有什么东西导致了这个问题,因为我之前没有这个错误。

我已经确保从数据库中获取的用户对象是一个用户对象,并且应该被传递到下一行代码中

错误信息

org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type 
[com.paphos.pos.users.Users] to type [@javax.persistence.ManyToOne @javax.persistence.JoinColumn com.paphos.pos.users.Users]

网络流

<evaluate result="user" expression="usersService.getCustomerById(1)"></evaluate>
<evaluate expression="order.users = flowScope.user"></evaluate>

用户服务

@Entity
@Table(name = "users")
@StaticMetamodel(Users.class)
public class Users implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private int idusers;

private String username;

private String password;

private int enabled = 0;
private String authority;

@Size(max = 25)
private String name;

@Size(min = 10, max = 10)
private String phoneNo;

@Size(min = 10, max = 10)
private String loyalty;

@OneToMany(cascade = CascadeType.ALL, mappedBy = "users")
private List<Timecard> timecard = new ArrayList<>();

订单

@Entity(name="orders")
public class Orders implements Serializable {
private static final long serialVersionUID = -8538332203504273656L;

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private int idorders;

@ManyToOne
@JoinColumn(name = "idusers")
private Users users;

@ManyToOne
@JoinColumn(name = "createdBy")
private Users createdBy;

@ManyToOne
@JoinColumn(name = "driver")
private Users driver;

@ManyToOne(cascade = { CascadeType.ALL })
@JoinColumn(name = "idaddresses")
private Addresses addresses;

private double pretax;

private double tax;

private double total;

@ManyToOne
@JoinColumn(name = "idstatus")
private Status status;

private String timeOrdered;

private int discounted;
private int tipped;
private Double due;

@OrderColumn
@OneToMany(fetch = FetchType.EAGER, cascade = { CascadeType.REMOVE }, mappedBy = "orders")
private Set<Orderitem> orderitem;

private double disAmount;
private double tipAmount;
private int paid;

我尝试将结果指定为 flowscope 或任何其他类型的变量,但没有任何效果。该错误也非常令人困惑,因为它是相同的类型,只是上面有注释。也许它与 webflow 配置有关,因为我在其他任何地方都没有收到此错误。如上所述,我刚刚更新到 sts 4,所以我要回到版本 3,看看是否是问题所在。任何帮助,将不胜感激。

解决方案


这个错误是由 pom.xml 中的 spring 开发工具引起的。从我的代码中删除它后,它开始工作。不知道为什么会这样。
