Spring Boot 2.x配置模板
@Configuration
public class WebMvcByFastjson implements WebMvcConfigurer {

@Bean
public HttpMessageConverter<Object> fastJsonHttpMessageConverter() {
// 1.需要先定义一个convert 转换消息的对象
FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();

// 2.添加fastJson的配置信息,比如，是否需要格式化返回的json数据
FastJsonConfig fastJsonConfig = new FastJsonConfig();

fastJsonConfig.setSerializeFilters((ValueFilter) (o, s, source) -> {
if (source instanceof LocalDateTime) {
return DateUtil.dateTimeAsString((LocalDateTime)source,"yyyy-MM-dd HH:mm:ss");
}
return source;
});
fastJsonConfig.setSerializerFeatures(
SerializerFeature.BrowserCompatible,
SerializerFeature.WriteNullStringAsEmpty
);

// 处理中文乱码问题
List<MediaType> fastMediaTypes = new ArrayList<>();
fastMediaTypes.add(MediaType.APPLICATION_JSON_UTF8);
fastConverter.setSupportedMediaTypes(fastMediaTypes);

// 3.在convert中添加配置信息
fastConverter.setFastJsonConfig(fastJsonConfig);
return fastConverter;
}

// 配置消息转换器
@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
converters.add(fastJsonHttpMessageConverter());

}
