添加打不开 有乱码

你好同学，你看一下你过滤器的<url-pattern>路径中是不是少写了个*好，导致所有请求路径没有被编码过滤器过滤呢，建议你修改一下试试呢，祝学习愉快~

import java.io.IOException;

public class EncodingFilter implements Filter {
    private String encoding="utf-8";
    @Override
    public void init(FilterConfig filterConfig) throws ServletException{
        if (filterConfig.getInitParameter("encoding")!=null){
            encoding=filterConfig.getInitParameter("encoding");
        }

    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        HttpServletResponse httpServletResponse=(HttpServletResponse)response;
        HttpServletRequest httpServletRequest=(HttpServletRequest)request;
        httpServletRequest.setCharacterEncoding(encoding);
        httpServletResponse.setCharacterEncoding(encoding);
        chain.doFilter(httpServletRequest,httpServletResponse);
    }

    @Override
    public void destroy() {

    }
}

<filter>
    <filter-name>enconding</filter-name>
    <filter-class>com.imooc.oa.global.EncodingFilter</filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>utf-8</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>enconding</filter-name>
    <url-pattern>/</url-pattern>
</filter-mapping>
