有关SpringMVC乱码问题

上述解决方法包括produce，uriEncoding等等
主要是在dispatcher-servlet.xml中加上编码配置：

 <!-- 设定消息转换的编码为utf-8防止controller返回中文乱码 -->
    <!-- <bean
            class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">

       <property name="messageConverters">
            <list>
                <bean
                        class="org.springframework.http.converter.StringHttpMessageConverter">
                    <constructor-arg value="#{T(java.nio.charset.Charset).forName('UTF-8')}"/>
                    <property name="supportedMediaTypes">
                        <list>
                            <value>text/html;charset=UTF-8</value>
                            <value>text/plain;charset=UTF-8</value>
                         &lt;!&ndash;   <value>application/json; charset=UTF-8</value>
                            <value>application/x-www-form-urlencoded; charset=UTF-8</value>&ndash;&gt;
                        </list>
                    </property>
                </bean>
            </list>
        </property>
    </bean>
    <bean
            class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
        <property name="supportedMediaTypes">
            <list>
                <value>application/json; charset=UTF-8</value>
                <value>application/x-www-form-urlencoded; charset=UTF-8</value>
            </list>
        </property>
    </bean>-->

上述链接中的解决方法都没解决我的问题，最后直接使用在web.xml中加入了编码的过滤器（dispatcher-servlet.xml中的编码设置都可以删除了）解决了。

 <!-- 解决工程编码过滤器 -->
    <filter>
        <filter-name>characterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
        <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
