本文详细介绍了如何在Tomcat服务器中配置UTF-8编码，包括server.xml的设置、数据库引擎编码调整、web.xml中CharacterEncodingFilter的使用及自定义过滤器实现，确保系统全面支持UTF-8字符集。

1、tomcat的server.xml中配置：

<Connector port="8900" protocol="HTTP/1.1"

connectionTimeout="20000"

redirectPort="8443" useBodyEncodingForURI="true"

maxParameterCount="100000"

maxHttpHeaderSize="100000"

URIEncoding="UTF-8" />

2、数据库引擎设置编码为utf-8

3、web.xml设置：

<filter>
   <filter-name>encodingFilter</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>
   <init-param>
      <param-name>forceEncoding</param-name>
      <param-value>true</param-value>
   </init-param>
</filter>
<filter-mapping>
   <filter-name>encodingFilter</filter-name>
   <url-pattern>/*</url-pattern>
</filter-mapping>

4、编写过滤器，设置utf-8

public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
   servletRequest.setCharacterEncoding("UTF8");
   servletResponse.setCharacterEncoding("UTF8");
   HttpServletRequest request = (HttpServletRequest) servletRequest;
   HttpServletResponse response = (HttpServletResponse) servletResponse;

}
