springMVC中接收post方式提交表单时出现中文乱码

解决方法：

1.手动开发一个Myfilter实现filter接口，代码如下

public class MyFilter implements Filter {
    //读取局部初始化参数
    private String encoding;
    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        encoding = filterConfig.getInitParameter("encoding");
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        request.setCharacterEncoding(encoding);
        response.setCharacterEncoding(encoding);
        chain.doFilter(request,response); //放行
    }

    @Override
    public void destroy() {

    }
}

2.配置web.xml

<!--解決post方式的中文乱码-->
<filter>
  <filter-name>charset</filter-name>
  <filter-class>com.rjxy.controller.MyFilter</filter-class>
  <!--设置局部初始化参数-->
  <init-param>
    <param-name>encoding</param-name>
    <param-value>UTF-8</param-value>
  </init-param>
</filter>
<filter-mapping>
  <filter-name>charset</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>
