Exemple détaillé du framework EasyUI utilisant Ajax pour soumettre les informations d'enregistrement

Cet article présente principalement les informations pertinentes sur le code d'implémentation du framework EasyUI utilisant Ajax pour soumettre les informations d'enregistrement. J'espère que cet article pourra aider tout le monde. Les amis dans le besoin pourront s'y référer.

Le framework EasyUI utilise Ajax pour soumettre le code de mise en œuvre des informations d'enregistrement

1. Code du serveur :

@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. Code BaseAction :

import com.opensymphony.xwork2.ModelDriven;

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

  /**

  private static final long serialVersionUID = 1L;
  @Resource

  @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;
  }
}
