解决SpringMVC乱码问题的方法

作者:互联网

1:使用过滤器,对所有请求进行过滤。

package com.kuang.filter;

import javax.servlet.*;
import java.io.IOException;

public class EncodingFilter implements Filter {

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {

    }

    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {

        servletRequest.setCharacterEncoding("utf-8");
        servletResponse.setCharacterEncoding("utf-8");
        filterChain.doFilter(servletRequest,servletResponse);
    }

    @Override
    public void destroy() {

    }
}
<!--过滤器-->
    <filter>
        <filter-name>encoding</filter-name>
        <filter-class>com.kuang.filter.EncodingFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>encoding</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

2:改变get,post的提交方式

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<form action="/e/t1" method="post">
    <input type="text" name="name">
    <input type="submit">
</form>
</body>
</html>

3:在SpringMVC中配置乱码解决

<!--配置SpringMVC的乱码过滤-->
    <filter>
        <filter-name>encoding</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>utf-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encoding</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

4:检查Tomcat中是否为UTF-8
