Dear All,
I have a JAX-RS & JPA application that worked fine under AS6 but now produces HTTP 500 errors when requesting JSON responses. I am trying to serialize the following class:
{code}
@Entity
@Table(name="countries")
@XmlRootElement(name="Country")
@XmlType(name="Country",propOrder={"name"})
@JsonAutoDetect({JsonMethod.NONE})
public class Country implements Serializable {
private static final long serialVersionUID = 4519728176152383566L;
private Integer id;
private Country parent;
private String name;
@Id
@GeneratedValue
@Column(name="country_id")
@XmlAttribute(name="id",required=true)
@JsonProperty
public Integer getId() {return id;}
public void setId(Integer id) {this.id = id;}
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumn(name="parent_id",referencedColumnName="country_id")
@XmlTransient
@JsonIgnore
public Country getParent() {return parent;}
public void setParent(Country parent) {this.parent = parent;}
@Column(name="name")
@XmlElement(name="Name",required=true)
@JsonProperty
public String getName() {return name;}
public void setName(String name) {this.name = name;}
}
{code}
The @Json annotations forced jackson to only include the correct properties. Under AS7, these annotations no longer seem to be having any effect, resulting in:
org.codehaus.jackson.map.JsonMappingException caused by ... org.hibernate.LazyInitializationException
This happens because jackson tries to serialize the 'parent' property of the Country class, which has not been eagerly fetched by the JPA query. I have tried several variations of the annotations but cannot find anything that works. Does anyone know the correct mix?
