springMVC中文传值乱码

一、 可统一页面字符编码

1. jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

2. html

<meta charset="UTF-8">

二、可修改 Tomcat 中 server.xml

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

三、可配置过滤器，修改web.xml

<filter>

    <filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name>

    <url-pattern>/*</url-pattern>

</filter-mapping>

四、统一数据库编码方式

jdbc.url=jdbc:mysql://localhost:3306/homeeducation?useUnicode=true&characterEncoding=UTF-8

五、java 单次接收并选择字符方式

new String(str.getBytes("ISO-8859-1"), "utf-8");
