spring mvc 表单提交 乱码

1。在web.xml添加过滤器：

<filter>
        <filter-name>SpringCharacterEncoding</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>SpringCharacterEncoding</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

2.spring-mvc 配置文件，配置自动扫描时：

    <mvc:annotation-driven>
        <mvc:message-converters register-defaults="true">
            <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                <property name="supportedMediaTypes">
                    <list>
                        <value>text/html;charset=UTF-8</value>
                        <value>text/json;charset=UTF-8</value>
                        <value>application/json;charset=UTF-8</value>
                    </list>
                </property>
            </bean>
        </mvc:message-converters>
    </mvc:annotation-driven>

3.post提交就没问题，而get可能还需要在方法上@RequestMapping注解添加produces参数

@RequestMapping(value="/selectPlaceListMap",produces = "text/html;charset=UTF-8")

4.以上不行，就修改eclipse自身配置的servers底下的server.xml

文件

修改：

<Connector URIEncoding="UTF-8" connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>

没有则添加，实际运行环境更改tomcat的server.xml即可。
