jsp中引入外部js文件发生中文乱码

jsp中引入外部js文件发生中文乱码

<script type="text/javascript" src="${pageContext.request.contextPath }/js/usermodify.js" charset="utf-8"></script>

引入js时指定编码charset="utf-8"

2.测试了许多办法都无法解决，最后在web.xml中添加如下配置就正常了

<web-app>
   ....
   <jsp-config>
       <jsp-property-group>
           <display-name>HtmlConfiguration</display-name>
           <url-pattern>*.html</url-pattern>
           <page-encoding>UTF-8</page-encoding>
       </jsp-property-group>
       <jsp-property-group>
           <display-name>JspConfiguration</display-name>
           <url-pattern>*.jsp</url-pattern>
           <page-encoding>UTF-8</page-encoding>
       </jsp-property-group>
       <jsp-property-group>
           <display-name>JsConfiguration</display-name>
           <url-pattern>*.js</url-pattern>
           <page-encoding>UTF-8</page-encoding>
       </jsp-property-group>
   </jsp-config>
   ....
</web-app>
