spring boot默認使用的json解析框架是jackson，替換為fastjson有兩種方式

1.繼承WebMvcConfigurerAdapter

@SpringBootApplication public class App extends WebMvcConfigurerAdapter{@Overridepublic 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);}public static void main(String[] args) {SpringApplication.run(App.class,args);} }

2.使用@Bean注入方式

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