SpringBoot与Layui框架

实习的时候，自己慢慢摸索使用Layui，刚开始看到这个框架就头疼，到现在只是了解了一部分，框架虽然精美，对于初学者来说没那么容易，经过两个星期的折腾，终于弄得像样了

以下部分内容，仅供参考！

                layer.closeAll('loading');
            }
        });

    });
</script>

Controller

@RestController
@RequestMapping("/user")
public class UserController {

    @Autowired
    UserService service;


    @RequestMapping("/getUsers")
    public Object getUsers(@RequestParam(defaultValue = "1") int page, @RequestParam(defaultValue = "10")int limit,HttpSession session){
        Map<String,Object> map = new HashMap<>();
        if (session.getAttribute("user")!=null){
            User user = (User)session.getAttribute("user");
            if (user.getPermission().equals("1")){

                try {
                    PageInfo<User> pageInfo= service.getUsers(page,limit);
                    map.put("data", pageInfo.getList());
                    map.put("code", 0);
                    map.put("msg", "请求成功");
                    map.put("count", pageInfo.getTotal());

                }catch (Exception e){
                    map.put("code","404");
                    map.put("msg","保存失败");
                    map.put("close","false");
                }
                return map;
            }else {
                map.put("msg","forbidden");
                map.put("code","403");
                map.put("error","无权限");
            }
        }else {
            map.put("msg","forbidden");
            map.put("code","404");
            map.put("error","请求错误");
        }

        return map;
    }
}

Service的实现类

@Service
public class UserServiceImpl implements UserService {
    @Autowired
    UserMapper mapper;

    /**
     * 查询所有用户并且分页
     * @param page
     * @param limit
     * @return
     */
    @Transactional(propagation = Propagation.REQUIRED, readOnly = true)
    @Override
    public PageInfo<User> getUsers(int page,int limit) {
        PageHelper.startPage(page, limit);
        List<User> users = mapper.getUsers();
        PageInfo<User> pageInfo = new PageInfo<>(users);
        return pageInfo;
    }

}

service 接口

public interface UserService {
    PageInfo<User> getUsers(int page,int limit);
}

Mapper 接口

主要用Mybatis注解查询

@Repository
@Mapper
public interface UserMapper {

    @Select("select * from user")
    List<User> getUsers();
}
