SpringMVC与fastjson整合并同时解决中文乱码问题

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：
[code]<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>
