jackson反序列化报：FAIL_ON_EMPTY_BEANS

Posted 2021-11-08 chenry777

异常：

org.springframework.http.converter.HttpMessageNotWritableException: Could not write content: No serializer found for class com.google.common.cache.CacheStats and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS)

原因：A反序列化成B，A的部分属性B中没有，会报这个错误

解决办法：

@Configuration
public class JacksonConfig {

    @Bean
    public ObjectMapper objectMapper() {
        return new ObjectMapper().disable(SerializationFeature.FAIL_ON_EMPTY_BEANS);
    }
}
