springmvc fastjson与Jackson的MessageConverter配置 http://ibear.me/2016/02/15/170 这里说明版本问题
原文： http://blog.51cto.com/boytnt/1771390
在servlet.xml配置：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
<mvc:annotation-driven> <mvc:message-converters register-defaults="true"> <bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter"> <property name="supportedMediaTypes" value="application/json"/> <!--设置fastjson特性--> <property name="features"> <array> <!--设置null值也要输出，fastjson默认是关闭的--> <value>WriteMapNullValue</value> <!--设置使用文本方式输出日期，fastjson默认是long--> <value>WriteDateUseDateFormat</value> </array> </property> </bean> </mvc:message-converters> </mvc:annotation-driven> |
这篇文章配置： https://github.com/alibaba/fastjson/issues/946
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 |
<bean id="fastJsonConfig" class="com.alibaba.fastjson.support.config.FastJsonConfig"> <!-- Default charset --> <property name="charset" value="UTF-8" /> <!-- SerializerFeature --> <property name="serializerFeatures"> <list> <value>QuoteFieldNames</value> <value>WriteMapNullValue</value> </list> </property> </bean> <mvc:annotation-driven> <mvc:message-converters register-defaults="true"> <!--将StringHttpMessageConverter的默认编码设为UTF-8--> <bean class="org.springframework.http.converter.StringHttpMessageConverter"> <constructor-arg value="UTF-8"/> </bean> <!-- 配置Fastjson支持 --> <bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>application/json</value> </list> </property> <property name="fastJsonConfig" ref="fastJsonConfig"/> </bean> </mvc:message-converters> </mvc:annotation-driven> |
最后测试经过的配置：
|
1 2 3 |
<bean name="utf8Charset" class="java.nio.charset.Charset" factory-method="forName"> <constructor-arg value="UTF-8"></constructor-arg> </bean> |
A1: 默认1
|
1 2 3 4 5 6 7 8 9 10 11 |
<mvc:annotation-driven> <mvc:message-converters> <bean class="org.springframework.http.converter.StringHttpMessageConverter"> <constructor-arg ref="utf8Charset"/> </bean> </mvc:message-converters> </mvc:annotation-driven> <bean class="org.springframework.http.converter.ByteArrayHttpMessageConverter"/> <bean class="org.springframework.http.converter.StringHttpMessageConverter"> <constructor-arg ref="utf8Charset"/> </bean> |
A2: 默认2
|
1 2 3 4 5 6 7 8 |
<mvc:annotation-driven> <mvc:message-converters> <bean class="org.springframework.http.converter.ByteArrayHttpMessageConverter"/> <bean class="org.springframework.http.converter.StringHttpMessageConverter"> <constructor-arg ref="utf8Charset"/> </bean> </mvc:message-converters> </mvc:annotation-driven> |
