SpringMVC与fastjson整合

今天试着把SpringMVC与fastjson整合了下，经测试也能解决json含中文乱码的问题，特此分享之。我也是初用，详细文档请见官网。
转换类：
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();
    }
}
SpringMVC关键配置：
<mvc:annotation-driven>
    <mvc:message-converters register-defaults="true">       
        <!-- fastjosn spring support -->
        <bean id="jsonConverter" class="com.alibaba.fastjson.spring.support.MappingFastJsonHttpMessageConverter">
            <property name="supportedMediaTypes" value="application/json" />
            <property name="serializerFeature">
                <list>
                    <value>WriteMapNullValue</value>
                    <value>QuoteFieldNames</value>
                </list>
            </property>
        </bean>
    </mvc:message-converters>
</mvc:annotation-driven>
