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：
EasyUI框架$(function(){
if(${"#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');
}
});
