SpringMVC3 AnnotationMethodHandlerAdapter与mvc:annotation-driven冲突的解决方案

1、问题

在使用SpringMVC3时，需要对response到页面的数据进行编码设置则需要自定义注解数据格式化类来对页面传过来的字符串进行格式化。

编码设置：

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" >  
        <property name="messageConverters">  
             <list>  
                 <bean class = "org.springframework.http.converter.StringHttpMessageConverter">  
                    <property name = "supportedMediaTypes">  
                         <list>  
                             <value>text/plain;charset=UTF-8</value>  
                         </list>  
                    </property>  
                 </bean>  
             </list>  
        </property>  
    </bean> 

Formatter设置:

<bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">  
	  <property name="formatters">  
	      <list>  
	          <bean class="com.grgbanking.it.common.formatter.TimestampFormatAnnotationFormatterFactory"/>  
	      </list>  
	  </property>  
	</bean> 
	<mvc:annotation-driven conversion-service="conversionService"/>

当两者按上面的设置好后，StringHttpMessageConverter不起作用了。

2、原因

<mvc:annotation-driven />的配置如下:

<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
		<property name="order" value="1" />
	</bean>
	<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
		<property name="webBindingInitializer">
		  <bean class="org.springframework.web.bind.support.ConfigurableWebBindingInitializer">
		   <property name="conversionService" ref="conversionService" />
		   <property name="validator" ref="validator" />
		  </bean>
		</property>
	</bean>
	<bean id="conversionService" class="org.springframework.samples.petclinic.util.PetclinicConversionServiceFactory" />
	<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean" /> 

所以我们在上面配置的AnnotationMethodHandlerAdapter在<mvc:annotation-driven />后是不起作用的。<mvc:annotation-driven />包括了一个默认的AnnotationMethodHandlerAdapter功能。

3、解决

<bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">  
	  <property name="formatters">  
	      <list>  
	          <bean class="com.grgbanking.it.common.formatter.TimestampFormatAnnotationFormatterFactory"/>  
	      </list>  
	  </property>  
	</bean> 
	
	<!-- 设置转换器 -->
	<mvc:annotation-driven conversion-service="conversionService">
		<mvc:message-converters>  
        	 <bean class = "org.springframework.http.converter.StringHttpMessageConverter">  
                    <property name = "supportedMediaTypes">  
                         <list>  
                             <value>text/plain;charset=UTF-8</value>  
                         </list>  
                    </property>  
                 </bean>  
        </mvc:message-converters>
	</mvc:annotation-driven>
