问题描述
我想开发一个小功能，在前台jsp中列出几个应用服务器，然后选中某个应用服务器后，将服务器IP发送到后台Servlet，由servlet用sshxcute远程登录并执行aix中的脚本文件，并将执行结果返回到前台jsp。遇到的问题：前台使用jQuery（mathod用post）提交数据，后台用servlet接受数据，前台发送不同的数据后台servlet都能接受到不同的数据，但执行后的结果却是每次都一样。开发环境：oracleweblogicworkshop10.3使用技术：ajax（jQuery），jqueryeasyui，sshxcute代码servletpackagezbgl.servlet;importjava.io.IOException;importjavax.servlet.ServletException;importjavax.servlet.http.HttpServlet;importjavax.servlet.http.HttpServletRequest;importjavax.servlet.http.HttpServletResponse;importzbgl.bean.AppServerBean;importzbgl.bean.CommonBean;publicclassAppServerServletextendsHttpServlet{privatestaticfinallongserialVersionUID=1L;AppServerBeanbean=newAppServerBean();CommonBeancb=newCommonBean();protectedvoiddoPost(HttpServletRequestrequest,HttpServletResponseresponse)throwsServletException,IOException{doGet(request,response);}protectedvoiddoGet(HttpServletRequestrequest,HttpServletResponseresponse)throwsServletException,IOException{request.setCharacterEncoding("UTF-8");response.setCharacterEncoding("UTF-8");Stringoper=request.getParameter("oper");//cb.sysout(oper);if(oper==null){cb.out(response,"{"SUCCESS":false,"MSG":"requestmethodisnull!"}");}elseif(oper.equalsIgnoreCase("getAppServerGrid"))bean.getAppServerGrid(request,response);//elseif(oper.equalsIgnoreCase("excuteScript")){newAppServerBean().executeScript(request,response);//}elseif(oper.equalsIgnoreCase("netMonitor"))newAppServerBean().netMonitor(request,response);//else{cb.out(response,"{"SUCCESS":false,"MSG":"+this.getServletName()+":nomethodforrequestmethod:"+oper+"!"}");}}}
