【问题描述】：
我有一个表 commandeClient，其中包含一个带有注释 json 的列表 ligneCommandesClients 忽略列表 ligneCommandeCLients
@Entity
public class CommandeClient implements Serializable {
@Id
@GeneratedValue
private Long idCdeClient;
private String codeCommande;
@Temporal(TemporalType.TIME)
private Date date;
@OneToMany(mappedBy="commandeClient")
private List<LigneCommandeClient>ligneCommandeClients;
@JsonIgnore
public List<LigneCommandeClient> getLigneCommandeClients() {
return ligneCommandeClients;
}
}
这里是实体 LigneCommandeClient
@Entity
public class LigneCommandeClient implements Serializable {
@Id
@GeneratedValue
private Long idLigneCommandeClient;
private BigDecimal qty;
private BigDecimal prixUnitaire;
@ManyToOne
@JoinColumn(name="idArticle")
private Article article;
@ManyToOne
@JoinColumn(name="idCdeClient")
private CommandeClient commandeClient;
在我的 jsp 中，我添加了一个 jquery 函数来加载 JSon 格式的 listCommandeClient，并使用调用以下方法的 onclick 事件
@Transient
public String getLigneCommandeJSON() {
if(!ligneCommandeClients.isEmpty()){
ObjectMapper mapper = new ObjectMapper();
try {
return mapper.writeValueAsString(ligneCommandeClients);
} catch (JsonGenerationException e) {
e.printStackTrace();
} catch (JsonMappingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
return "";
}
但是在执行以下指令将列表转换为 json 对象时
return mapper.writeValueAsString(ligneCommandeClients);
我一直重复这个错误，没有根本原因（删除了这个错误的重复次数）
