EasyUI框架 使用Ajax提交注册信息的实现代码

EasyUI框架 使用Ajax提交注册信息的实现代码

一、服务器代码：

@Controller
@Scope("prototype")
public class StudentAction extends BaseAction<Student> {
  private static final long serialVersionUID = -2612140283476148779L;

  private Logger logger = Logger.getLogger(StudentAction.class);
  private String rows;// 每页显示的记录数
  private String page;// 当前第几页
  private Map<String, Object> josnMap = new HashMap<>();

  // 查询出所有学生信息
  public String list() throws Exception {
    return "list";
  }

  public String regUI() throws Exception {
    return "regUI";
  }

  // 查询出所有学生信息
  public String listContent() throws Exception {
    List<Student> list = studentService.getStudentList(page, rows);
    System.out.println("list==" + list);
    toBeJson(list, studentService.getStudentTotal());
    return "toJson";
  }

  // 转化为Json格式
  public void toBeJson(List<Student> list, int total) throws Exception {
    josnMap.put("total", total);
    josnMap.put("rows", list);
    JSONParser.writeJson(josnMap);// 自定义的工具类
  }

  public String reg(){
    logger.error("kkk");
    try {
      studentService.save(model);
      josnMap.put("success", true);
      josnMap.put("msg", "注册成功!");
    } catch (Exception e) {
      e.printStackTrace();
      josnMap.put("success", false);
      josnMap.put("msg", "注册失败!");
    }
    try {
      ServletActionContext.getResponse().setContentType("text/html;charset=utf-8");
      ServletActionContext.getResponse().setCharacterEncoding("utf-8");
      ServletActionContext.getResponse().getWriter().print(JSON.toJSONString(josnMap));
    } catch (IOException e) {
      e.printStackTrace();
    }

    return "toJson";
  }

  public void setRows(String rows) {
    this.rows = rows;
  }

  public void setPage(String page) {
    this.page = page;
  }

  public Map<String, Object> getJosnMap() {
    return josnMap;
  }

  public void setJosnMap(Map<String, Object> josnMap) {
    this.josnMap = josnMap;
  }

}

二、BaseAction代码：

import java.lang.reflect.ParameterizedType;

import javax.annotation.Resource;

import org.apache.struts2.ServletActionContext;

import cn.oppo.oa.service.DepartmentService;
import cn.oppo.oa.service.ForumService;
import cn.oppo.oa.service.PrivilegeService;
import cn.oppo.oa.service.RoleService;
import cn.oppo.oa.service.StudentService;
import cn.oppo.oa.service.UserService;

import com.alibaba.fastjson.JSON;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;

public abstract class BaseAction<T> extends ActionSupport implements ModelDriven<T> {

  /**
   *
   */
  private static final long serialVersionUID = 1L;
  @Resource
  protected RoleService roleService;
  @Resource
  protected DepartmentService departmentService;
  @Resource
  protected UserService userService;
  @Resource
  protected PrivilegeService privilegeService;

  @Resource
  protected ForumService forumService;

  @Resource
  protected StudentService studentService;

  protected T model;

  @SuppressWarnings("unchecked")
  public BaseAction() {
    try {
      // 得到model的类型信息
      ParameterizedType pt = (ParameterizedType) this.getClass().getGenericSuperclass();
      Class<T> clazz = (Class<T>) pt.getActualTypeArguments()[0];

      // 通过反射生成model的实例
      model = (T) clazz.newInstance();
    } catch (Exception e) {
      throw new RuntimeException(e);
    }
  }

  public void writeJson(Object object){
    try {
      String json = JSON.toJSONStringWithDateFormat(object, "yyyy-MM-dd HH:mm:ss");
      ServletActionContext.getResponse().setContentType("text/html;charset=utf-8");
      ServletActionContext.getResponse().setCharacterEncoding("utf-8");
      ServletActionContext.getResponse().getWriter().write(json);
      ServletActionContext.getResponse().getWriter().flush();
      ServletActionContext.getResponse().getWriter().close();
    } catch (Exception e) {
      e.printStackTrace();
    }
  }

  public T getModel() {
    return model;
  }
}

三、页面代码：

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<html>
<head>
  <title>EasyUI框架</title>
  <%@ include file="/WEB-INF/jsp/public/common.jspf" %>
  <script type="text/javascript">
     $(function(){
       if(${"#easyui_regForm"}.form('validate')){
         $.ajax({
           url:'${pageContext.request.contextPath}/student_reg.action',
           data:${"#easyui_regForm"}.serialize(),
           dataType:'json',
           success:function(obj,status,jqXHR){
             if(obj.success){
               $("#easyui_regDialog").dialog('close');
             }
             $.message.show({
              title:'提示',
              msg:obj.msg
             });
           }
         });
       }else{
         alert('验证失败');
       }
    });
  </script>

            var obj = jQuery.parseJSON(data);
            if (obj.success) {

        }
      },{

        handler:function(){alert('注册')}
      }]" >
    <form id="easyui_regForm" method="post">
    <table>
