jsp外部引入js文件出现中文乱码

1.设置项目编码为utf-8

2.删除相关文件并重新创建编码为utf-8的同名文件

3.设置jsp头、html的meta、引用的js链接为utf-8

<%@ page language="java" import="java.util.*" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

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

4.过滤器设置请求内容编码和响应内容编码

public void doFilter(ServletRequest request, ServletResponse response,
      FilterChain chain) throws IOException, ServletException {
   // TODO Auto-generated method stub
   request.setCharacterEncoding("UTF-8");
   response.setCharacterEncoding("UTF-8");
   chain.doFilter(request, response);
}

5.设置tomcat配置文件server.xml

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

6.设置web.xml

<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>
