EasyUI框架 使用Ajax提交注册信息的实现代码

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 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";

}
