无法反序列化包含从AMQP消息传递接收的LocalDate的对象

时间:2016-07-13 06:52:47

标签: java json serialization jackson amqp

我尝试通过AMQP消息传递(RabbitMQ)发送一个对象但是当我收到消息时,转换器引发了一个JsonMappingException,因为它无法反序列化该消息。

import com.fasterxml.jackson.datatype.joda.ser.LocalDateSerializer;
import org.joda.time.LocalDate;

1 个答案:

答案 0 :(得分:3)

首先,您应该添加以下maven依赖项:

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

其次,您应该使用以下命令更新MessasgeConverter bean:

@Bean
public MessageConverter messageConverter()
{
    ObjectMapper mapper = new ObjectMapper().findAndRegisterModules();

    return new Jackson2JsonMessageConverter(mapper);
}

在此次更新后,您不需要使用&#34; JsonSerialize&#34;注释
