1.用户查询
2.case when的处理
UserDao.java
public List<User> list(User user, PageBean pageBean) throws Exception { String sql = "select * from t_oa_user where 1=1 "; String name = user.getName(); if (StringUtils.isNotBlank(name)) sql += " and name like '%" + name + "%'"; return super.executeQuery(sql, User.class, pageBean); } public List<Map<String, Object>> listUserRole(User user, PageBean pageBean) throws Exception { String sql = "select *,\r\n" + "(case rid\r\n" + "when 1 then '管理人员'\r\n" + "when 4 then '参与者'\r\n" + "else '其他角色' end) as rname\r\n" + "from t_oa_user "; String name = user.getName(); if (StringUtils.isNotBlank(name)) sql += " and name like '%" + name + "%'"; return super.executeQuery(sql, pageBean); } public int add(User user) throws Exception { String sql = "insert into t_oa_user(name,loginName,pwd) values(?,?,?)"; return super.executeUpdate(sql, user, new String[] {"name","loginName","pwd"}); } public int edit(User user) throws Exception { String sql = "update t_oa_user set name = ?,loginName = ?,pwd = ? where id = ?"; return super.executeUpdate(sql, user, new String[] {"name","loginName","pwd","id"}); } public int del(User user) throws Exception { String sql = "delete from t_oa_user where id = ?"; return super.executeUpdate(sql, user, new String[] {"id"}); }
UserAction.java
public String listUserRole(HttpServletRequest req, HttpServletResponse resp) { try { PageBean pageBean = new PageBean(); pageBean.setRequest(req); List<Map<String, Object>> users = userDao.listUserRole(user, pageBean); // layui 的code 返回一定要是 0，不能是200，否者返回不了数据 ResponseUtil.writeJson(resp, R.ok(0, "查询成功", pageBean.getTotal(), users)); } catch (Exception e) { e.printStackTrace(); try { ResponseUtil.writeJson(resp, R.error(0, "查询失败")); } catch (Exception e1) { e1.printStackTrace(); } } return null; }

3.用户新增
UserAction.java
public String add(HttpServletRequest req, HttpServletResponse resp) { try { int rs = userDao.add(user); if (rs > 0) { ResponseUtil.writeJson(resp, R.ok(200, "用户新增成功")); }else { ResponseUtil.writeJson(resp, R.error(0, "用户新增失败")); } } catch (Exception e) { e.printStackTrace(); try { ResponseUtil.writeJson(resp, R.error(0, "用户新增失败")); } catch (Exception e1) { e1.printStackTrace(); } } return null; } public String edit(HttpServletRequest req, HttpServletResponse resp) { try { int rs = userDao.edit(user); if (rs > 0) { ResponseUtil.writeJson(resp, R.ok(200, "用户修改成功")); }else { ResponseUtil.writeJson(resp, R.error(0, "用户修改失败")); } } catch (Exception e) { e.printStackTrace(); try { ResponseUtil.writeJson(resp, R.error(0, "用户修改失败")); } catch (Exception e1) { e1.printStackTrace(); } } return null; } public String del(HttpServletRequest req, HttpServletResponse resp) { try { int rs = userDao.del(user); if (rs > 0) { ResponseUtil.writeJson(resp, R.ok(200, "用户删除成功")); }else { ResponseUtil.writeJson(resp, R.error(0, "用户删除失败")); } } catch (Exception e) { e.printStackTrace(); try { ResponseUtil.writeJson(resp, R.error(0, "用户删除失败")); } catch (Exception e1) { e1.printStackTrace(); } } return null; }

4.用户修改
5.用户删除
userManage.js
//1.初始化数据表格 function initTable(){ table.render({ //执行渲染 elem: '#tb', //指定原始表格元素选择器（推荐id选择器） // url: 'user.action?methodName=list', //请求地址 height: 340, //自定义高度 loading: false, //是否显示加载条（默认 true） cols: [[ //设置表头 {field: 'id', title: '用户编号', width: 120}, {field: 'name', title: '用户名', width: 120}, {field: 'loginName', title: '登录账号', width: 140}, {field: '', title: '操作', width: 220,toolbar:'#toolbar'}, ]] }); //在页面中的<table>中必须配置lay-filter="tb_goods"属性才能触发属性!!! table.on('tool(tb)', function (obj) { row = obj.data; if (obj.event == "edit") { open("编辑"); }else if(obj.event == "del"){ layer.confirm('确认删除吗?', {icon: 3, title:'提示'}, function(index){ $.post($("#ctx").val()+'/user.action',{ 'methodName':'del', 'id':row.id },function(rs){ if(rs.success){ //调用查询方法刷新数据 query(); }else{ layer.msg(rs.msg,function(){}); } },'json'); layer.close(index); }); }else{ } }); }
