}

代码实现

1. 表现层

    /*** 分页查询角色信息*/@ApiOperation(value = "分页查询角色信息")@PostMapping("/roles")public R<RoleDataRespVo> getRolesData(@RequestBody HashMap<String,Object> pageMsg){return UserService.getRolesData(pageMsg);

2. 服务层

R<RoleDataRespVo> getRolesData(HashMap<String, Object> pageMsg);

@Overridepublic R<RoleDataRespVo> getRolesData(HashMap<String, Object> pageMsg) {// 设置分页参数Integer pageNum = (Integer) pageMsg.get("pageNum");Integer pageSize = (Integer) pageMsg.get("pageSize");PageHelper.startPage(pageNum, pageSize);// 获取数据ArrayList<SysRole> allRole = sysRoleMapper.getAllRole();PageInfo<SysRole> sysRolePageInfo = new PageInfo<>(allRole);RoleDataRespVo roleDataRespVo = new RoleDataRespVo(sysRolePageInfo);return R.ok(roleDataRespVo);}

3. Dao层

ArrayList<SysRole> getAllRole();

    <select id="getAllRole" resultType="com.jixu.stock.pojo.entity.SysRole">select id,name,description,status,create_time,update_time,deletedfrom sys_role</select>
