字符集过滤器

一. 可以用Spring的字符集过滤器, 具体配置如下:

  1. 在web.xml 中配置如下代码

  web.xml

<!-- spring的字符集过滤器 -->  
    <filter>  
        <filter-name>springCharacterEncodingFilter</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>springCharacterEncodingFilter</filter-name>  
        <url-pattern>/*</url-pattern>  
    </filter-mapping>

 

二. 可以自己写一个过滤器, 步骤如下:

 1. CharacterEncodingFilter.java

 

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

public class CharacterEncodingFilter implements Filter {

	public void init(FilterConfig arg0) throws ServletException {
		// TODO Auto-generated method stub
	}

	public void doFilter(ServletRequest request, ServletResponse response,
			FilterChain filterchain) throws IOException, ServletException {
		request.setCharacterEncoding("utf-8");
		response.setCharacterEncoding("utf-8");
		filterchain.doFilter(request, response);
	}

	public void destroy() {
	}

}

 

2. 在web.xls配置如下

<!-- 字符集过滤器 -->
	<filter>
		<filter-name>CharacterEncodingFilter</filter-name>
		<filter-class>
			com.huapu.sms.util.CharacterEncodingFilter
		</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>CharacterEncodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
