Spring3升级Spring4（maven） springmavenmvc

1、升级Spring jar版本3.X-4.X

2、升级spring xmlns 版本由3.X.xsd升级到4.X.xsd

3、多视图
org.springframework.http.converter.json.MappingJacksonHttpMessageConverter升级org.springframework.http.converter.json.MappingJackson2HttpMessageConverter

	<bean class="com.fasterxml.jackson.databind.ObjectMapper" id="objectMapper">
		<!-- 处理responseBody 里面日期类型 -->
		<property name="dateFormat">
			<bean class="java.text.SimpleDateFormat">
				<constructor-arg index="0" type="java.lang.String"
					value="yyyy-MM-dd HH:mm:ss" />
			</bean>
		</property>
		<property name="serializationInclusion">
			<value type="com.fasterxml.jackson.annotation.JsonInclude.Include">NON_EMPTY</value>
		</property>
	</bean>
	<mvc:annotation-driven>
		<mvc:message-converters>
			<bean
				class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
				<property name="supportedMediaTypes">
					<list>
						<value>application/json;charset=UTF-8</value>
					</list>
				</property>
				<property name="objectMapper">
					<ref bean="objectMapper" />
				</property>
			</bean>
			<bean class="org.springframework.http.converter.StringHttpMessageConverter">
				<!--避免出现乱码 -->
				<constructor-arg value="UTF-8" index="0"></constructor-arg>
				<property name="supportedMediaTypes">
					<list>
						<value>text/plain;charset=UTF-8</value>
					</list>
				</property>
			</bean>
		</mvc:message-converters>
	</mvc:annotation-driven>

4、org.springframework.web.servlet.view.ContentNegotiatingViewResolver属性defaultViews 由org.springframework.web.servlet.view.json.MappingJacksonJsonView变更org.springframework.web.servlet.view.json.MappingJackson2JsonView；
以前属性：

		<property name="ignoreAcceptHeader" value="true" />
		<property name="defaultContentType" value="text/html" />
		<property name="mediaTypes">
			<map>
				<entry key="json" value="application/json;charset=UTF-8" />
				<entry key="xml" value="application/xml;charset=UTF-8" />
			</map>
		</property>
		<property name="favorParameter" value="false" />

变更

   <bean id="contentNegotiationManager"  class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
        <property name="favorPathExtension" value="true" />
        <property name="ignoreAcceptHeader" value="true"/>
        <property name="useJaf" value="false"/>
        <property name="defaultContentType" value="text/html" />
        <property name="mediaTypes">
            <map>
                <entry key="html" value="text/html"/>
                <entry key="json" value="application/json;charset=UTF-8" />
				<entry key="xml" value="application/xml;charset=UTF-8" />
           </map>
        </property>
    </bean>


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