[實踐]Spring MVC——消息轉換器的編碼（防止中文亂碼）

今天配置了一下消息轉換器，測試的時候發現中文是亂碼的，tomcat和mysql的編碼設置沒有問題，logger出來也是正常的，因此發現應該是消息轉換器沒有設置好MediaType，修正了一下：

@Override
    public void configureMessageConverters(
            List<HttpMessageConverter<?>> converters
    ) {
        converters.add(new ByteArrayHttpMessageConverter());
        StringHttpMessageConverter stringHttpMessageConverter = new StringHttpMessageConverter();
        stringHttpMessageConverter.setSupportedMediaTypes(Arrays.asList(
                new MediaType("text", "plain", Charset.forName("utf-8")),
                new MediaType("text", "html", Charset.forName("utf-8"))
        ));
        converters.add(stringHttpMessageConverter);
        converters.add(new FormHttpMessageConverter());
        converters.add(new SourceHttpMessageConverter<>());

        //add json converter
        MappingJackson2HttpMessageConverter jsonConverter =
                new MappingJackson2HttpMessageConverter();
        jsonConverter.setSupportedMediaTypes(Arrays.asList(
                new MediaType("application", "json", Charset.forName("utf-8")),
                new MediaType("text", "json", Charset.forName("utf-8")),
                new MediaType("application", "x-www-form-urlencoded", Charset.forName("utf-8"))
        ));
        jsonConverter.setObjectMapper(this.objectMapper);
        converters.add(jsonConverter);

        //add xml converter
        MarshallingHttpMessageConverter xmlConverter =
                new MarshallingHttpMessageConverter();
        xmlConverter.setSupportedMediaTypes(Arrays.asList(
                new MediaType("application", "xml", Charset.forName("utf-8")),
                new MediaType("text", "xml", Charset.forName("utf-8"))
        ));
        xmlConverter.setMarshaller(this.marshaller);
        xmlConverter.setUnmarshaller(this.unmarshaller);
        converters.add(xmlConverter);
    }
