關閉Spring Boot的Jsckson的FAIL_ON_EMPTY_BEANS

說明：Spring Boot中默認使用了Jackson做JSON的解析。

解決方法：

1、通過注入Bean來實現

錯誤：

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)

解決：

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