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，代码以下

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>
