3 spring mvc
3.1 fastjson的使用
配置:
<!-- 设置配置方案 --> <mvc:annotation-driven> <!-- 设置不使用默认的消息转换器 --> <mvc:message-converters register-defaults="false"> <!-- 配置Spring的转换器 --> <bean class="org.springframework.http.converter.StringHttpMessageConverter"/> <bean class="org.springframework.http.converter.xml.XmlAwareFormHttpMessageConverter"/> <bean class="org.springframework.http.converter.ByteArrayHttpMessageConverter"/> <bean class="org.springframework.http.converter.BufferedImageHttpMessageConverter"/> <!-- 配置fastjson中实现HttpMessageConverter接口的转换器 --> <bean id="fastJsonHttpMessageConverter" class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter"> <!-- 加入支持的媒体类型:返回contentType --> <property name="supportedMediaTypes"> <list> <!-- 这里顺序不能反,一定先写text/html,不然ie下会出现下载提示 --> <value>text/html;charset=UTF-8</value> <value>application/json;charset=UTF-8</value> </list> </property> </bean> </mvc:message-converters> </mvc:annotation-driven>
对于返回String类型的数据乱码:
<!-- 配置Spring的转换器, 字符编码 --> <bean class="org.springframework.http.converter.StringHttpMessageConverter"> <constructor-arg value="UTF-8" index="0"/> <property name="supportedMediaTypes"> <list> <value>text/plain;charset=UTF-8</value> </list> </property> </bean>
