完善注册功能

[Episode8]

相关代码：
public void register(HttpServletRequest request, HttpServletResponse response) throws IOException {
Worker worker = new Worker();
//封装worker对象
worker.setNumber(request.getParameter("number"));
worker.setPassword(request.getParameter("password"));
worker.setName(request.getParameter("name"));
worker.setGender(Integer.parseInt(request.getParameter("gender")));
worker.setHiredate(Date.valueOf(request.getParameter("hiredate")));
worker.setPosition_id(Integer.parseInt(request.getParameter("position")));
worker.setPhone_number(request.getParameter("phone_number"));
//调用注册方法
WorkerService workerService = new WorkerServiceImp();
ResultInfo register = workerService.register(worker);
//设置响应体参数
response.setContentType("application/json;charset=utf-8");
ObjectMapper om = new ObjectMapper();
//返回json数据
om.writeValue(response.getWriter(), register);
}
