springboot利用fastjson序列化输出(默认是jackson)

在@SpringBootApplication类中添加

    @Bean
    public HttpMessageConverters fastJsonHttpMessageConverters() {
        //创建FastJson信息转换对象
        FastJsonHttpMessageConverter fastJsonHttpMessageConverter = new FastJsonHttpMessageConverter();
        //创建FastJson对象并设定序列化规则
        FastJsonConfig fastJsonConfig = new FastJsonConfig();
        fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);
        fastJsonHttpMessageConverter.setSupportedMediaTypes(Arrays.asList(MediaType.APPLICATION_JSON_UTF8));
        //规则赋予转换对象
        fastJsonHttpMessageConverter.setFastJsonConfig(fastJsonConfig);
        return new HttpMessageConverters(fastJsonHttpMessageConverter, new StringHttpMessageConverter(Charset.forName("UTF-8")));
    }
