spring3 升级Spring4 需要注意的地方

1.修改msgconvert

<!-- 注入fastjson配置类 -->
<bean name="fastJsonConfig" class="com.alibaba.fastjson.support.config.FastJsonConfig">
   <property name="serializerFeatures">
      <list>
         <value>WriteMapNullValue</value>
         <value>WriteMapNullValue</value>

         <value>WriteNullNumberAsZero</value>
         <value>WriteNullListAsEmpty</value>
         <value>WriteNullStringAsEmpty</value>
         <value>WriteNullBooleanAsFalse</value>
         <value>WriteDateUseDateFormat</value>
      </list>
   </property>
</bean>

 

<!-- 配置多请求数据类型，如json xml -->
<mvc:annotation-driven  conversion-service="conversionService" content-negotiation-manager="contentNegotiationManager">
   <mvc:message-converters register-defaults="true">
      <bean class="org.springframework.http.converter.FormHttpMessageConverter"/>
      <bean class="org.springframework.http.converter.BufferedImageHttpMessageConverter"/>
      <bean class="org.springframework.http.converter.ByteArrayHttpMessageConverter"/>
      <bean class="org.springframework.http.converter.StringHttpMessageConverter">
         <property name="supportedMediaTypes">
            <list>
               <value>application/xml</value>
               <value>text/html;charset=UTF-8</value>
            </list>
         </property>
      </bean>
      <bean class="org.springframework.http.converter.ResourceHttpMessageConverter"/>
      <bean class="org.springframework.http.converter.StringHttpMessageConverter">
         <constructor-arg value="UTF-8"/>
         <property name="supportedMediaTypes">
            <list>
               <value>application/json;charset=UTF-8</value>
            </list>
         </property>
      </bean>

 <bean id = "mappingJackson2HttpMessageConverter"

class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
   <property name="supportedMediaTypes">
      <list>
         <value>application/json;charset=UTF-8</value>
      </list>
   </property>
   <!-- 配置 -->
<property name="fastJsonConfig" ref="fastJsonConfig"/>
</bean>       
 </mvc:message-converters>

    </mvc:annotation-driven>

 

2.移除asm jar包

3.若在jboss中使用

jboss-deployment-structure 添加

<module name="org.jboss.as.jsf-injection" />

<module name="com.fasterxml.jackson.core.jackson-core"/>

<module name="com.fasterxml.jackson.core.jackson-databind"/>

<module name="com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider"/>

<module name="org.jboss.resteasy.resteasy-jackson2-provider"/>

否则可能出现(即使你引用的jar类包含):

Caused by: java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.ObjectWriter.forType(Lcom/fasterxml/jackson/databind/JavaType;)Lcom/fasterxml/jackson/databind/ObjectWriter;

 

4.freeMarker升级到2.3.23

 

5. Not Acceptable

修改 contentNegotiationManager 配置

<bean id="contentNegotiationManager"
class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean" >
   <property name="favorPathExtension" value="false"/>
</bean>


<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
   <property name="order" value="0"/>
   <property name="contentNegotiationManager" ref="contentNegotiationManager"/>

   <property name="defaultViews">
      <list>
         <bean class="com.alibaba.fastjson.support.spring.FastJsonJsonView">
            <property name="charset" value="UTF-8"/>
         </bean>
      </list>
   </property>
</bean>
