假设以下 REST 资源:
@Path("/ActiveLeadTask")
//Also possible MediaType.APPLICATION_XML
@Produces(MediaType.APPLICATION_JSON)
public class ActiveLeadTask {
private @Inject ActiveLeadTaskBo activeLeadBo;
@GET
@Path("/getBo")
public ActiveLeadTaskBo getBo() {
return activeLeadBo;
}
}
////////////////////////////////////////////////////
@XmlRootElement
@XmlAccessorType(XmlAccessType.PUBLIC_MEMBER)
public class ActiveLeadTaskBo implements Serializable {
private static final long serialVersionUID = 1L;
private String firstName;
private String lastName;
private String phoneNumber;
private String phoneCountryCode;
private AtomicInteger accessCounterField = new AtomicInteger(0);
public ActiveLeadTaskBo() {
firstName = "test";
lastName = "test";
}
public int getAccessCounter() {
return accessCounterField.incrementAndGet();
}
public void setAccessCounter(int seed) {
accessCounterField.set(seed);
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
}
getBo() JSON(但不是 XML)的 REST 响应返回以下内容:
{
"accessCounter": 1,
"firstName": "test",
"lastName": "test",
"metadata": {
"contextualInstance": {
"accessCounter": 2,
"firstName": "test",
"lastName": "test"
},
"instance": {
"accessCounter": 3,
"firstName": "test",
"lastName": "test"
}
}
}
JSON 响应包含一个额外的“元数据”字段——如何将项目配置为不生成它,或者避免生成它?CDI 容器是 Weld,而 JSON 序列化程序由 Yasson 提供。
