java里SpringMVC接收中文数据乱码问题

java里SpringMVC接收中文数据后会有乱码问题，只用在web.xml里添加以下代码即可

<!-- 中文乱码问题 -->
    <filter>
		<filter-name>characterEncodingFilter</filter-name>

		<init-param>

			<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>

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