页面代码:
var setting = {
async:{
enable:true,
contentType:"application/json",
dataType:"text",
url:"/root/treeServlet",
autoParam:["id","pId","name","isParent"]
}
};
$(document).ready(function(){
$.fn.zTree.init($("#tree"), setting);
});
Servlet代码
@WebServlet(name = "TreeServlet", urlPatterns = {"/treeServlet"})
public class TreeServlet extends HttpServlet {
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("application/json");
response.setCharacterEncoding("UTF-8");
PrintWriter out = response.getWriter();
try {
System.out.println(functionAction.getJson());
out.write(functionAction.getJson());
} finally {
out.flush();
out.close();
}
}
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
try {
functionAction.get();
} catch (SQLException ex) {
Logger.getLogger(TreeServlet.class.getName()).log(Level.SEVERE, null, ex);
}
processRequest(request, response);
}
控制台格式:[{id:'1',pId:'0',name:'系统设置',isParent:'true'}];
