# 配置方法一 #

\*\*1、导入第三方的jackson包，jackson-mapper-asl-1.9.7.jar和jackson-core-asl-1.9.7.jar。

2、[spring][]配置文件添加\*\*

<mvc:annotation-driven/>
    
      
        <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">  
            <property name="supportedMediaTypes">  
                <list>  
                    <value>text/html;charset=UTF-8</value>  
                </list>  
            </property>  
        </bean>  
    
          
        <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">  
            <property name="messageConverters">  
                <list>  
                    <ref bean="mappingJacksonHttpMessageConverter" />  
                </list>  
            </property>  
        </bean>

# 配置方案二(常用) #

\*\*1、导入第三方的fastjson包，fastjson-1.1.34.jar   
2、Spring配置文件添加：\*\*

<mvc:annotation-driven>
            <mvc:message-converters register-defaults="true">
                
                <bean id="fastJsonHttpMessageConverter" class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
                    <property name="supportedMediaTypes">
                        <list>
                            <value>application/json;charset=UTF-8</value>
                        </list>
                    </property>
                </bean>
            </mvc:message-converters>
        </mvc:annotation-driven>

# 配置方案三 #

\* 1、需要导入 jackson-annotations-\*.jar,jackson-core-.jar,jackson-databind-.jar   
2、在spring中添加配置\*\*

<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping" />
        <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
            <property name="messageConverters">
                <list>
                    <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                        <property name="supportedMediaTypes">
                            <list>
                                <value>text/html; charset=UTF-8</value>
                                <value>application/json;charset=UTF-8</value>
                            </list>
                        </property>
                    </bean>
                    <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
                        <property name="supportedMediaTypes">
                            <list>
                                <value>text/html; charset=UTF-8</value>
                                <value>application/json;charset=UTF-8</value>
                            </list>
                        </property>
                    </bean>
                </list>
