이 글은 등록 정보 제출을 위해 Ajax를 사용한 EasyUI 프레임워크 구현 코드에 대한 관련 정보를 주로 소개합니다. 도움이 필요한 모든 분들에게 도움이 되기를 바랍니다.

EasyUI 프레임워크는 Ajax를 사용하여 등록 정보 구현 코드를 제출합니다

1. 서버 코드: 


@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;
  }



}

2. BaseAction 코드:

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;
  }
}
