关闭Spring Boot的Jsckson的FAIL_ON_EMPTY_BEANS

说明：Spring Boot中默认使用了Jackson做JSON的解析。

解决方法：

1、通过注入Bean来实现

错误：

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)

解决：

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