Spring-MVC配置Gson做为Message Converter解析Json--通过注解配置

WebMvcConfigurerAdaptor 已经过时. 现在需要 implement WebMvcConfigurer

@Configuration
@EnableWebMvc
public class WebApp implements WebMvcConfigurer {@Overridepublic void configureMessageConverters(List<HttpMessageConverter<?>> converters) {converters.add(createGsonHttpMessageConverter());WebMvcConfigurer.super.configureMessageConverters(converters);}private GsonHttpMessageConverter createGsonHttpMessageConverter() {Gson gson = new GsonBuilder().setDateFormat("yyyy-MM-dd HH:mm:ss").create();GsonHttpMessageConverter gsonConverter = new GsonHttpMessageConverter();gsonConverter.setGson(gson);return gsonConverter;}
}
