SpringBoot 配置FastJson , Google百度一下一大堆 , 我就贴一下我的方式:

• extends org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter

• Override configureMessageConverters

4    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {

5        super.configureMessageConverters(converters);

6       //fastjson MessageConverter

7        FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();

8       //fastjson config

9        FastJsonConfig fastJsonConfig = new FastJsonConfig();

10        fastJsonConfig.setSerializerFeatures(SerializerFeature.WriteMapNullValue);

11        

12        List<MediaType> fastMediaTypes = new ArrayList<>();

13      //MediaType : application/json;charset=UTF-8

14        fastMediaTypes.add(MediaType.APPLICATION_JSON_UTF8);

15      

16        fastConverter.setSupportedMediaTypes(fastMediaTypes);

17        //fastjson config add to converter

18        fastConverter.setFastJsonConfig(fastJsonConfig);

19        

20        HttpMessageConverter<?> converter = fastConverter;

21      //String MessageConverter , charset : UTF-8

22        StringHttpMessageConverter stringConverter  = new StringHttpMessageConverter(Charset.forName("UTF-8"));

23      //remove response accept charset

24        stringConverter.setWriteAcceptCharset(false);

25      //config StringHttpMessageConverter MediaType

26        List<MediaType> stringSupportedMediaTypes = stringConverter.getSupportedMediaTypes();

27        //StringHttpMessageConverter MediaType : application/json;charset=UTF-8

28        stringSupportedMediaTypes.add(MediaType.APPLICATION_JSON_UTF8);

29        stringConverter.setSupportedMediaTypes(stringSupportedMediaTypes);

31        converters.add(stringConverter);

32        converters.add(converter);

33    }

34}

1. FastJsonHttpMessageConverter 在FastJson包里,直接引入就可以了.
2. fastMediaTypes.add(MediaType.APPLICATION_JSON_UTF8); // 配置fastjson支持的mediaType为utf8,支持中文
3. 配置StringHttpMessageConverter

• 不配置StringHttpMessageConverter的话
  • return "abc";
  • 经过fastjson处理后 , 拿到的是 ""abc"";
• 配置StringHttpMessageConverter 的 MediaType 为: application/json;charset=UTF-8, 支持中文
• 将两个Converter添加到list
