springMVC解决GET与POST乱码

springMVC解决POST乱码在web.xml中配置一个编码过滤器即可解决,而解决GET乱码需要在服务器端配置或者对参数重新编码。

1,解决POST乱码

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>

2,解决GET乱码

对于get请求中文参数出现乱码解决方法有两个:

(1)、就tomcat举例,修改tomcat配置文件添加编码与工程编码一致,如下:

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

(2)、另外一种方法对参数进行重新编码:
String userName new String(request.getParamter("userName").getBytes("ISO8859-1"),"utf-8")
ISO8859-1是tomcat默认编码,需要将tomcat编码后的内容按utf-8编码
