springMVC解决中文乱码问题

1.post请求乱码问题

在web.xml中加入:

<filter>

<filter-name>CharacterEncodingFilterfilter-name>

<filter-class>org.springframework.web.filter.CharacterEncodingFilterfilter-class>

<init-param>

<param-name>encodingparam-name>

<param-value>utf-8param-value>

init-param>

filter>

<filter-mapping>

<filter-name>CharacterEncodingFilterfilter-name>

<url-pattern>/*url-pattern>

filter-mapping>

 

2.对于get请求中文参数出现乱码解决方法有两个:

修改tomcat配置文件添加编码与工程编码一致,如下:

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

 

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
