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”)));
}
