乱码问题

 

方法一：

1 编写一个过滤器，提前设置好编码格式

public class encodingfIlter implements Filter {
    public void init(FilterConfig filterConfig) throws ServletException {

    }

    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.xml中设置过滤器

<filter>
    <filter-name>encode</filter-name>
    <filter-class>filter.encodingfIlter</filter-class>
</filter>
<filter-mapping>
    <filter-name>encode</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>


方法二：
直接再XML里配置

<filter>
    <filter-name>encode</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
        <param-name>encode</param-name>
        <param-value>utf-8</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>encode</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
