SpringBoot 集成 fastJson

两种形式：

1.

(1)启动类继承extends WebMvcConfigurerAdapter

(2)覆盖方法configureMessageConverters

@Override     public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {         super.configureMessageConverters(converters);                FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();           FastJsonConfig fastJsonConfig = new FastJsonConfig();         fastJsonConfig.setSerializerFeatures(                 SerializerFeature.PrettyFormat         );         fastConverter.setFastJsonConfig(fastJsonConfig);                converters.add(fastConverter);     }

2.在Application.java启动类中，注入Bean : HttpMessageConverters

@Bean  public HttpMessageConverters fastJsonHttpMessageConverters() {        FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();        FastJsonConfig fastJsonConfig = new FastJsonConfig();        fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);        fastConverter.setFastJsonConfig(fastJsonConfig);        HttpMessageConverter<?> converter = fastConverter;        return new HttpMessageConverters(converter);     }
