我在解析你的约会时遇到了问题 JSON ，当我的程序消耗 POST 包含 Body ，而不是 REST 客户端程序 Postman 效果很好。
使用带有url的 Postman http://localhost：8080/api/v1/customers/createpurchaser

带收割台

我的程序客户端控制台的输出是：
java.time.format.datetimeparseexception:无法在索引0处分析文本“653038060000”
我的程序客户端的代码( ConsumingServices 类）是：

import java.sql.Timestamp;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.concurrent.TimeUnit;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.client.Entity;
import javax.ws.rs.client.Invocation;
import javax.ws.rs.client.WebTarget;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

public class ConsumingServices {

    public static void main(String[] args) {
        Customer customer = new Customer();
        customer.setFirstName("John");
        customer.setLastName("Mason");
        customer.setEmail("john.mason@mail.com");
        customer.setDateOfBirth(new Date());
        customer.setStatus(CustomerStatus.ACTIVE);

        ClientBuilder clientBuilder = ClientBuilder.newBuilder();
        clientBuilder.connectTimeout(1000, TimeUnit.SECONDS);
        clientBuilder.readTimeout(1000, TimeUnit.SECONDS);
        Client client = clientBuilder.build();

        WebTarget target = client.target("http://localhost:8080/api/v1/customers");

        Invocation.Builder invocationBuilder = target.path("createPurchaser")
                .request(MediaType.APPLICATION_JSON)
                .accept(MediaType.APPLICATION_JSON)
                ;

        Response response = invocationBuilder
                .header("Authorization", "1234")
                .post(Entity.entity(customer, MediaType.APPLICATION_JSON));

        System.out.println("response.getStatus():" + response.getStatus());
        if (response.getStatus() == Response.Status.OK.getStatusCode()) {
            Purchaser purchaser = response.readEntity(Purchaser.class);
            System.out.println("purchaser:".concat(purchaser.toString()));
        } else {
            if (MediaType.TEXT_PLAIN_TYPE.equals(response.getMediaType())) {
                String message = response.readEntity(String.class);
                System.out.println("message:" + message);
            } else if (MediaType.APPLICATION_JSON.equals(response.getMediaType())) {
                ApiError apiError = response.readEntity(ApiError.class);
                System.out.println("apiError:".concat(apiError.toString()));
            } else {
                System.out.println("response.getMediaType():" + response.getMediaType());
                String content = response.readEntity(String.class);
                System.out.println("message:" + content);
            }
        }
    }
}

输出：

这个 Customer 类（问题中的所有代码是javax.ws.rs.processingexception，在payara server 5中找不到内容类型application/json类型的writer）

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;
    }
}

如何在我的客户机中解决这个问题（使用 ClientBuilder/WebTarget) 程序，如果使用rest客户端程序工作正常？？

你的问题很可能是在解析你的 Customer 在客户机程序中将示例类化为json。请注意，在postman中，您已经提供了正确的json（您希望 Customer 类示例将被解析为），但在客户端程序中，您希望您的http客户端代码解析 Customer 在这段代码中将示例类化为json：

Response response = invocationBuilder
            .header("Authorization", "1234")
            .post(Entity.entity(customer, MediaType.APPLICATION_JSON));

但是，日期被解析为“653038060000”，正如错误消息告诉您的那样。因此，我建议首先测试我的假设是否正确，尝试发送json文本而不是 Customer 类示例。如果我的假设是正确的，这就行了。如果是这样的话，那么您需要确保无论以何种方式解析 Customer json的类示例是正确的。或者自己使用一些json库（我建议jacksonjson，githubjacksonhome）。以下是maven工件：

<groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-core</artifactId>
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.datatype</groupId>
        <artifactId>jackson-datatype-jsr310</artifactId>
    </dependency>

)或者获取您的http客户端 Invocation.Builder 正确解析。为此，您可能需要在customer类中添加以下注解：

@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd'T'HH:mm:ss.SSSZ")
   private Date dateOfBirth;

您可能需要向代码中添加相同的jacksonmaven工件。关于详细的答案，请参阅这个问题：SpringDataJPA-ZoneDateTime格式用于json序列化，如果您使用的是Java8或更高版本，我强烈建议不要使用过时的 Date 类（没有双关语），但切换到 java.time 打包并使用localdate类或其他可用类，如 LocalDateTime 或者 ZonedDateTime 或者其他人。最后，如果您愿意，您可以尝试另一个来自mgntutils库的3d方http客户端。下面是它的javadoc:httpclient。这个库本身可以在这里作为maven工件和github上找到（包括源代码和javadoc）。这个库不将类解析为json，但是可以将文本作为请求体发送(免责声明：这个库是我写的）。
