一、 可统一页面字符编码
- jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
- 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");
