@Configuration
public class WebMvcConfigurer extends WebMvcConfigurerAdapter {
	@Override
	public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
		super.configureMessageConverters(converters);
		// 1.需要定义一个convert转换消息的对象
		FastJsonHttpMessageConverter fastConvert = new FastJsonHttpMessageConverter();
		// 2.添加fastJson的配置信息，比如：是否格式化返回的json数据
		FastJsonConfig fastJsonConfig = new FastJsonConfig();
		fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);
		// 3.在convert中添加配置信息
		fastConvert.setFastJsonConfig(fastJsonConfig);
		// 4.将convert添加到converters当中
		converters.add(fastConvert);
