ClientBuilder / WebTarget程序中带有DateTimeParseException / JsonbException的JSON解析日期

问题描述

当我的程序使用包含JSON的{{1}}服务而不是POST客户端程序Body时，我无法解析REST的日期效果很好。

使用邮递员的URL http：// localhost：8080 / api / v1 / customers / createPurchaser

带有页眉

我的程序客户端控制台的输出是：

java.time.format.DateTimeParseException：无法在索引0处解析文本'653038060000'

我的程序客户端（Postman类）的代码是：

ConsumingServices

输出：

                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);
            }
        }
    }
}

样式输出。

Customer

我的程序客户端的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; } }依赖项是：

pom.xml

如果使用REST客户端程序可以正常工作，如何在客户端中解决此问题（使用<dependencies> <dependency> <groupId>com.acme</groupId> <artifactId>acme-customers-lib</artifactId> <version>1.0.0-SNAPSHOT</version> </dependency>  <dependency> <groupId>org.glassfish.jersey.core</groupId> <artifactId>jersey-client</artifactId> <version>2.31</version> </dependency>  <dependency> <groupId>org.glassfish.jersey.inject</groupId> <artifactId>jersey-hk2</artifactId> <version>2.31</version> </dependency>  <dependency> <groupId>org.glassfish.jersey.media</groupId> <artifactId>jersey-media-json-jackson</artifactId> <version>2.31</version> </dependency> </dependencies>程序？

解决方法

您的问题很可能是在客户端程序中将Customer类实例解析为JSON。请注意，在Postman中，您已经提供了正确的JSON（您希望将Customer类实例解析为JSON），但是在客户端程序中，您希望Http客户端代码来解析Customer类在这段代码中将实例转换为JSON：

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

但是，正如错误消息告诉您的那样，日期已解析为“ 653038060000”。因此，我建议首先测试我的假设是否正确，尝试从客户端程序发送JSON文本而不是Customer类实例。如果我的假设是正确的，那将会奏效。如果是这样，则您需要确保将Customer类实例解析为JSON的任何方法都是正确的。可以自己使用一些JSON库（我建议Jackson Json，GitHub Jackson home。这是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>

）或让您的Http客户端Invocation.Builder正确解析它。为此，您可能需要在Customer类中添加以下注释：

   @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Jackson Maven工件。有关详细的答案，请参见以下问题：Spring Data JPA - ZonedDateTime format for json serialization 另外，如果您使用的是Java 8或更高版本，我非常强烈，建议不要使用过时的Date类（无双关语），而是改用java.time软件包并改用{ {3}}类或其他可用类，例如LocalDateTime或ZonedDateTime或其他。最后，如果您愿意，可以尝试使用MgntUtils库中的另一个3d派对Http客户端。这是它的JavaDoc：LocalDate。您可以在HttpClient和Maven Artifacts上找到该库本身（包括源代码和Javadoc）。该库虽然不会将类解析为JSON，但可以将文本作为请求正文发送。（免责声明：这个库是我写的。）
