后台管理系统 - 管理员管理模块

该模块提供管理员列表展示、添加、删除等功能，实现对系统管理员的管理。

代码示例

package org.example.web.backstage.adminmanage;

import org.example.model.Admin;
import org.example.service.AdminService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import javax.servlet.http.HttpServletRequest;
import java.util.List;

@Controller
@RequestMapping("/backstage/adminmanage")
public class AdminManageController {

    @Autowired
    private AdminService adminService;

    @RequestMapping(value = "/all", method = RequestMethod.GET)
    //跳转到管理员列表
    public String readAdmins(HttpServletRequest request) {
        List<Admin> admins = adminService.getAdmins();
        request.setAttribute("list", admins);
        //跳转到管理员列表页面
        return "/jsp/backstage/adminmanage/adminmanage.jsp";
    }

    @RequestMapping(value = "/delete", method = RequestMethod.GET)
    public String deleteAdmin(Integer id) {
        //删除指定账户
        adminService.deleteAdmin(id);
        //返回管理员列表页
        return "/backstage/adminmanage/all";
    }

    //跳转到账户添加页面
    @RequestMapping(value = "/toAddAdmin", method = RequestMethod.GET)
    public String toAddAdmin() {
        return "/jsp/backstage/adminmanage/adminadd.jsp";
    }

    //执行账户添加请求，将页面传递过来的账号信息存储到数据库
    @RequestMapping(value = "/doAddAdmin", method = RequestMethod.POST)
    public String  doAddAdmin(HttpServletRequest request,Admin admin) {
        if (admin.getUsername().equals("")) {
            request.setAttribute("message", "账户名不能为空");
            return "/jsp/backstage/adminmanage/adminadd.jsp";
        } else if (admin.getName().equals("")) {
            request.setAttribute("message", "姓名不能为空");
            return "/jsp/backstage/adminmanage/adminadd.jsp";
        } else if (admin.getSex() == null) {
            request.setAttribute("message", "必须选择性别");
            return "/jsp/backstage/adminmanage/adminadd.jsp";
        } else {
            //接收页面传递的参数并保存到数据库
            adminService.saveAdmin(admin);
            //跳转到账户添加页面
            return "redirect:/backstage/adminmanage/toAddAdmin";
        }
    }






}

重定向问题

"return "redirect:/backstage/adminmanage/toAddAdmin"" 不生效的原因可能是跳转路径不正确或者请求方法不匹配。请检查路径是否正确，并确保请求方法为POST。另外，还需要确认是否存在拦截器或过滤器对请求进行了重定向的处理。
