SpringMVC與fastjson整合並同時解決中文亂碼問題

 今天試着把SpringMVC與fastjson整合了下，經測試也能解決json含中文亂碼的問題，特此分享之。我也是初用，詳細文檔請見官網。

轉換類：

public class MappingFastJsonHttpMessageConverter extends
        AbstractHttpMessageConverter<Object> {
    public static final Charset DEFAULT_CHARSET = Charset.forName("UTF-8");

    private SerializerFeature[] serializerFeature;

    public SerializerFeature[] getSerializerFeature() {
        return serializerFeature;
    }

    public void setSerializerFeature(SerializerFeature[] serializerFeature) {
        this.serializerFeature = serializerFeature;
    }

    public MappingFastJsonHttpMessageConverter() {
        super(new MediaType("application", "json", DEFAULT_CHARSET));
    }

    @Override
    public boolean canRead(Class<?> clazz, MediaType mediaType) {
        return true;
    }

    @Override
    public boolean canWrite(Class<?> clazz, MediaType mediaType) {
        return true;
    }

    @Override
    protected boolean supports(Class<?> clazz) {
        throw new UnsupportedOperationException();
    }

    @Override
    protected Object readInternal(Class<?> clazz, HttpInputMessage inputMessage)
    throws IOException, HttpMessageNotReadableException {
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        int i;
        while ((i = inputMessage.getBody().read()) != -1) {
            baos.write(i);
        }
        return JSON.parseArray(baos.toString(), clazz);
    }

    @Override
    protected void writeInternal(Object o, HttpOutputMessage outputMessage)
    throws IOException, HttpMessageNotWritableException {
        String jsonString = JSON.toJSONString(o, serializerFeature);
        OutputStream out = outputMessage.getBody();
        out.write(jsonString.getBytes(DEFAULT_CHARSET));
        out.flush();
    }
}
