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 {  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 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 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 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 getJosnMap() {    return josnMap;  }  public void setJosnMap(Map 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 extends ActionSupport implements ModelDriven {  /**   *    */  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 clazz = (Class) 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"%>  EasyUI框架  <%@ 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');       }    });     aa
    cc
   dd
  kk
      
              登陆名称：               
              登陆密码：               
    
  
      
                  登陆名称：               
              登陆密码：               
              确定密码：

四、struts2.xml配置

                                                                                  /WEB-INF/jsp/user/loginUI.jsp      /noPrivilegeError.jsp                  /test.jsp              /WEB-INF/jsp/{1}/{2}.jsp            /WEB-INF/jsp/{1}/saveUI.jsp            {1}_list?parentId=${parentId}            /index.jsp            topic_show?id=${id}      topic_show?id=${topicId}                    josnMap            /easyui.jsp
