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 BaseActionextends 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; } }
