The second way to use the @bean label
/** * Here we use the @Bean to inject Fastjsonhttpmessageconvert * @return * */@Beanpublic Httpmessageconverters Fastjsonhttpmessageconverters () {///1, the object that needs to first define a convert conversion message; Fastjsonhttpmessageconverter fastconverter = new Fastjsonhttpmessageconverter ();//2, add Fastjson configuration information, For example: whether to format the returned JSON data; Fastjsonconfig fastjsonconfig = new Fastjsonconfig (); Fastjsonconfig.setserializerfeatures ( Serializerfeature.prettyformat);//3, add configuration information in convert. Fastconverter.setfastjsonconfig (fastjsonconfig); httpmessageconverter<?> converter = Fastconverter;return new Httpmessageconverters (converter);}
