SpringMVC Controller层中 request接收参数乱码

直接使用

String email = request.getParameter("email");

 接收到email是乱码，需要转换

email = new String(request.getParameter("email").getBytes("ISO-8859-1"),"UTF-8");

 这样麻烦还需要处理异常。

还可以这么解决：

web.xml

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