• spring mvc 中文参数乱码


    最近做项目,springmvc的url中文参数乱码:

    请求url:

    http://localhost:8080/supply/supply_list.htm?productName=测试&isHomePage=

    在后端:

    @RequestMapping(value = SupplyURL.SUPPLY_LIST, method = RequestMethod.GET)
        public String toSupplyList (Model model, String productName) {
    
            PageBean<Supply> pagination = supplyFacade.querySupplyByPage(searchSupplyVO);
            
            model.addAttribute("searchSupplyVO", searchSupplyVO);return "/supply/supply_list";
        }

    这里productName的值就变成了乱码,

    检查我的web的web.xml中已经增加了过滤中文编码的:

    <!-- Character Encoding filter -->
        <filter>
            <filter-name>encodingFilter</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>encodingFilter</filter-name>
            <url-pattern>/*</url-pattern>
        </filter-mapping>

    但是还是乱码。

    仔细检查了,还是中间容器tomcat导致的。修改tomcat的conf/server.xml中的

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

    加上useBodyEncodingForURI="true"  URIEncoding="UTF-8" 。即可。

    比如我要下载

    http://localhost:8080/template/档案模板.xls

    会转义成如下的,此时如果加上 URIEncoding="UTF-8" ,则可以在webapp/template/目录下找到文件。不会再报404了。

    http://localhost:8080/template/%E5%AD%A6%E7%94%9F%E6%A1%A3%E6%A1%88%E5%AF%BC%E5%85%A5%E6%A8%A1%E6%9D%BF.xls
