SpringMVC配置了过滤器依然乱码

Question

idea的maven项目
① 编码过滤器在核心控制器前面
②使用的是本地tomcat 9.0
server.xml也修改了

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

web.xml

<!DOCTYPE web-app PUBLIC
        "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
        "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
    <display-name>Archetype Created Web Application</display-name>

    <!--配置解决post方式提交中文乱码问题-->
    <filter>
        <filter-name>characterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <!--指定字符编码为UTF-8-->
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>


    <!--配置核心控制器 spring mvc的入口-->
    <servlet>
        <servlet-name>dispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!--核心控制器加载配置文件-->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:springmvc.xml</param-value>
        </init-param>
        <!--服务器启动时创建DispatcherServlet核心控制器对象-->
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

Answer 1

1，server.xml 第一行检查下 是否有 UTF-8。
并且将你贴的那个改成这样
2，坚持页面是否有UTF-8 。 <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
