用servlet提交 WangEditor3编辑的内容，找了很多资料没发现，大多用的框架，今天终于解决了，记录一下。
WangEditor3不支持放在textarea中，servlet是无法直接获取到编辑器中的内容的，有一下两种方法：
方法一：如果想用form表单提交需要加个textarea，此时的textarea应该隐藏起来，用js获取WangEditor3编辑的内容，再赋值给textarea，再form提交，隐藏textarea如下：
<textarea name="newscontent" id="content" style="width:100%; height:200px;display:none" ></textarea>
方法二：可以用ajax通过用js取出表单和富文本中的内容，通过json格式传输，在后台获取就可以了。
注明：以下演示以方法二为例，方法一在代码中注释掉了。

新建Servlet ContentPublish
package com.liu.Controller; import java.io.IOException; import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; /** * Servlet implementation class ContentPublish */ @WebServlet("/contentpublish") public class ContentPublish extends HttpServlet { private static final long serialVersionUID = 1L; /** * @see HttpServlet#HttpServlet() */ public ContentPublish() { super(); // TODO Auto-generated constructor stub } /** * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response) */ protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub response.getWriter().append("Served at: ").append(request.getContextPath()); } /** * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response) */ protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub System.out.println("post"); String newsMan=request.getParameter("newsMan"); String newsTitle=request.getParameter("newsTitle"); String introduce=request.getParameter("introduce"); System.out.println(newsMan); System.out.println(newsTitle); System.out.println(introduce); } }
效果如下：
