SpringAop之request取不到formdata的數據的處理

在web.xml中配置：

<filter>
        <filter-name>InitContent</filter-name>
        <filter-class>com.common.filter.InitContent</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>InitContent</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

InitContent.java

public class InitContent implements Filter {

    @Override
    public void destroy() {
        // TODO Auto-generated method stub

    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {
        // TODO Auto-generated method stub
         HttpServletRequest httpRequest = (HttpServletRequest) request;
            String contentType = httpRequest.getContentType();
            if (contentType != null && contentType.contains("multipart/form-data")) {
                MultipartResolver resolver = new CommonsMultipartResolver(httpRequest.getSession().getServletContext());
                MultipartHttpServletRequest multipartRequest = resolver.resolveMultipart(httpRequest);
                // 將轉化後的 request 放入過濾鏈中
                request = multipartRequest;
            }
            chain.doFilter(request, response);
    }

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

    }

}
