问题：我该如何解决这个异常？
我的课程代码......
The CustomerResource class
@Path("/customers")
@ApplicationScoped
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public class CustomerResource {
@POST
@Path("/createPurchaser")
public Response createPurchaser(Customer customer) {
return Response
.status(Response.Status.OK)
.entity(customerService.createPurchaser(customer))
.type(MediaType.APPLICATION_JSON)
.build();
}
}
The CustomerService界面
public interface CustomerService {
Purchaser createPurchaser(Customer customer);
}
The createPurchaser的方法CustomerServiceImpl class
@ApplicationScoped
public class CustomerServiceImpl implements CustomerService {
@Override
public Purchaser createPurchaser(Customer customer) {
if (customer == null) {
throw new EmptyPayloadException(Customer.class.getSimpleName());
}
Purchaser client = new Purchaser();
client.setFirstName(customer.getFirstName());
client.setLastName(customer.getLastName());
client.setAffiliationDate(new Date());
client.setCustomerStatus(CustomerStatus.ACTIVE);
client.setPurchaserDocument(new PurchaserDocument());
client.getPurchaserDocument().setDateOfBirth(customer.getDateOfBirth());
client.getPurchaserDocument().setNumberDocument(new Random().nextLong());
client.getPurchaserDocument().setTypeDocument("CC");
return client;
}
}
The Customer class
import java.io.Serializable;
import java.util.Date;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement
public class Customer extends BaseType implements Serializable {
private String firstName;
private String lastName;
private CustomerStatus status;
private String email;
private Date dateOfBirth;
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;
}
public CustomerStatus getStatus() {
return status;
}
public void setStatus(CustomerStatus status) {
this.status = status;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public Date getDateOfBirth() {
return dateOfBirth;
}
public void setDateOfBirth(Date dateOfBirth) {
this.dateOfBirth = dateOfBirth;
}
}
Now the BaseType class
import java.util.Date;
public class BaseType {
private String id;
private Date createdAt;
private Date updatedAt;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public Date getCreatedAt() {
return createdAt;
}
public void setCreatedAt(Date createdAt) {
this.createdAt = createdAt;
}
public Date getUpdatedAt() {
return updatedAt;
}
public void setUpdatedAt(Date updatedAt) {
this.updatedAt = updatedAt;
}
}
the CustomerStatus enum
public enum CustomerStatus {
ACTIVE, INACTIVE
}
The Purchaser class
import java.io.Serializable;
import java.util.Date;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement
public class Purchaser implements Serializable {
private String firstName;
private String lastName;
private Date affiliationDate;
private CustomerStatus customerStatus;
private PurchaserDocument purchaserDocument;
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;
}
public Date getAffiliationDate() {
return affiliationDate;
}
public void setAffiliationDate(Date affiliationDate) {
this.affiliationDate = affiliationDate;
}
public CustomerStatus getCustomerStatus() {
return customerStatus;
}
public void setCustomerStatus(CustomerStatus customerStatus) {
this.customerStatus = customerStatus;
}
public PurchaserDocument getPurchaserDocument() {
return purchaserDocument;
}
public void setPurchaserDocument(PurchaserDocument purchaserDocument) {
this.purchaserDocument = purchaserDocument;
}
@Override
public String toString() {
StringBuilder sb = new StringBuilder();
sb.append("Purchaser{firstName=").append(firstName);
sb.append(", lastName=").append(lastName);
sb.append(", affiliationDate=").append(affiliationDate);
sb.append(", customerStatus=").append(customerStatus);
sb.append(", purchaserDocument=").append(purchaserDocument);
sb.append('}');
return sb.toString();
}
}
The PurchaserDocument class
import java.io.Serializable;
import java.util.Date;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement
public class PurchaserDocument implements Serializable {
private String typeDocument;
private Long numberDocument;
private Date dateOfBirth;
public String getTypeDocument() {
return typeDocument;
}
public void setTypeDocument(String typeDocument) {
this.typeDocument = typeDocument;
}
public Long getNumberDocument() {
return numberDocument;
}
public void setNumberDocument(Long numberDocument) {
this.numberDocument = numberDocument;
}
public Date getDateOfBirth() {
return dateOfBirth;
}
public void setDateOfBirth(Date dateOfBirth) {
this.dateOfBirth = dateOfBirth;
}
}
问题是jersey-client依赖性。您需要将其删除。原因：通用ClientBuilder is 建于always成为一个JerseyClientBuilder https://github.com/jax-rs/api/blob/master/jaxrs-api/src/main/java/javax/ws/rs/client/ClientBuilder.java#L94当 Jersey 客户端位于类路径上时。您拥有的 JSON 依赖项（自动向 RESTEast 客户端注册）resteasy-jackson2-provider用于RESTEasy。所以 Jersey 客户端不认识它。您可以手动向客户端注册提供程序，它应该可以工作。
client.register(JacksonJaxbJsonProvider.class);
但就像我说的，只需删除jersey-client and ClientBuilder会变成ResteasyClientBuilder并且它会识别resteasy-jackson2-provider并自动注册。除非你的目标is使用Jersey客户端，此时需要手动注册provider，或者添加Jersey自动注册依赖，即jersey-media-json-jackson.
请注意，如果您计划在服务器环境中使用客户端，我刚刚注意到您正在使用 Payara，它在幕后使用 Jersey。所以服务器已经配备了所有 Jersey jars。如果您想使用 Jackson 作为您的提供者，您应该添加jersey-media-json-jackson并注册JacksonFeature与客户。如果您不这样做，它将默认使用 JSONB 作为 JSON 提供程序。如果你想使用RESTEasy，那么你可以忘记这一点。
