本文介绍如何在SpringMVC中配置ContentNegotiatingViewResolver实现多视图解析，支持不同格式如HTML, JSON, PDF的响应。同时，讲解了自定义数据转换器StringToDateConverter的创建方法，用于处理日期类型的输入。

配置多视图解析器：ContentNegotiatingViewResolver

Springmvc配置文件中

<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
 <property name="contentNegotiationManager">
<bean class="org.springframework.web.accept.ContentNegotiationManager">
<constructor-arg>
    <list>
    <!-- These are evaluated in order -->
    <!-- Is there a media type based on suffix? -->
<bean                  class="org.springframework.web.accept.PathExtensionContentNegotiationStrategy">
<constructor-arg>
    <map>
<entry key="html" value="text/html" />
<entry key="json" value="application/json" />
<entry key="pdf" value="application/pdf" />
</map>
</constructor-arg>
</bean>
<!-- Else use request header -->
<bean

上面配置在SpringMVC3.2不可以用换成下面的

<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
 <property name="contentNegotiationManager">
<bean class="org.springframework.web.accept.ContentNegotiationManager">
<constructor-arg>
    <list>
    <!-- These are evaluated in order -->
    <!-- Is there a media type based on suffix? -->
<bean                  class="org.springframework.web.accept.PathExtensionContentNegotiationStrategy">
<constructor-arg>
    <map>
<entry key="html" value="text/html" />
<entry key="json" value="application/json" />
<entry key="pdf" value="application/pdf" />
</map>
</constructor-arg>
</bean>
<!-- Else use request header -->
<bean

Controller

<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
 <property name="contentNegotiationManager">
<bean class="org.springframework.web.accept.ContentNegotiationManager">
<constructor-arg>
    <list>
    <!-- These are evaluated in order -->
    <!-- Is there a media type based on suffix? -->
<bean                  class="org.springframework.web.accept.PathExtensionContentNegotiationStrategy">
<constructor-arg>
    <map>
<entry key="html" value="text/html" />
<entry key="json" value="application/json" />
<entry key="pdf" value="application/pdf" />
</map>
</constructor-arg>
</bean>
<!-- Else use request header -->
<bean

数据转换和格式化

编写自定义转换器
1创建StringToDateConverter.java

<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
 <property name="contentNegotiationManager">
<bean class="org.springframework.web.accept.ContentNegotiationManager">
<constructor-arg>
    <list>
    <!-- These are evaluated in order -->
    <!-- Is there a media type based on suffix? -->
<bean                  class="org.springframework.web.accept.PathExtensionContentNegotiationStrategy">
<constructor-arg>
    <map>
<entry key="html" value="text/html" />
<entry key="json" value="application/json" />
<entry key="pdf" value="application/pdf" />
</map>
</constructor-arg>
</bean>
<!-- Else use request header -->
<bean

以后Controller继承BaseController就可以了
