SpringMVC出现中文乱码

从浏览器传来的参数如果是中文,就会出现乱码问题,可以使用拦截器来解决乱码问题

web.xml

<filter>
    <filter-name>UTF8Filter</filter-name>
    <filter-class>com.wzx.filter.UTF8Filter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>UTF8Filter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

UTF8Filter

public class UTF8Filter implements Filter {
    public void destroy() {
    }

    public void doFilter(ServletRequest req, ServletResponse resp, FilterChain chain) throws ServletException, IOException {
        req.setCharacterEncoding("utf-8");
        resp.setContentType("text/html;charset=utf-8");
        chain.doFilter(req, resp);
    }

    public void init(FilterConfig config) throws ServletException {

    }

}
