Spring boot入门(三):SpringBoot集成结合AdminLTE(Freemarker),利用generate自动生成代码,利用DataTable和PageHelper进行分页显示

  关于SpringBoot和PageHelper,前篇博客已经介绍过Spring boot入门(二):Spring boot集成MySql,Mybatis和PageHelper插件,前篇博客大致讲述了SpringBoot如何集成Mybatis和Pagehelper,但是没有做出实际的范例,本篇博客是连接上一篇写的。通过AdminLTE前端框架,利用DataTable和PageHelper进行分页显示,通过对用户列表的增删改查操作,演示DataTable和PageHelper的使用。

(1)AdminLTE介绍

  AdminLTE是一个完全响应管理模板。基于Bootstrap3框架,易定制模板。适合多种屏幕分辨率,从小型移动设备到大型台式机。内置了多个页面,包括仪表盘、邮箱、日历、锁屏、登录及注册、404错误、500错误等页面。具体介绍见官方网站:https://adminlte.io/,我们可以直接从此网站下载该模板,其外观如下:

(2)SpringBoot后台集成AdminLTE

  首先在官网下载AdminLTE模板,然后将此模板的全部文件拷贝到项目下:

Spring boot入门(三):SpringBoot集成结合AdminLTE(Freemarker),利用generate自动生成代码,利用DataTable和PageHelper进行分页显示

  拷贝后,将AdminLTE文件进行了拆分,其中base里面是AdminLTE自带的所有js包和css文件,main中是AdminLTE主页面渲染页面,index是入口。这么做的目的:直接将base通过FreeMarker中宏的形式引入到index入口页面中,那么所有的js文件将一直曾在最底层的页面下,在后期的其它页面的开发中,不需要再次引入js包,避免js包混乱。

  (3)配置generate

  generate的介绍比较多,此处直接介绍配置的步骤及代码

  增加依赖jar包,在build下增加

</configuration>
</plugin>

  编写generatorConfig.xml文件,并放在templates根目录下,若放在其它目录中,则需要在pom.xml中配置路径,否则,编译的时候无法通过。具体错误:

generatorConfig.xml的脚本如下,其中targetProject的路径需要曾在,否则会报错,参考https://blog.csdn.net/hh680821/article/details/79051870

12,enableUpdateByExample(默认true):MyBatis3Simple为false,指定是否生成动态修改语句(只修改对象中不为空的属性);
13,modelType:参考context元素的defaultModelType,相当于覆盖;
14,delimitIdentifiers:参考tableName的解释,注意,默认的delimitIdentifiers是双引号,如果类似MYSQL这样的数据库,使用的是`(反引号,那么还需要设置context的beginningDelimiter和endingDelimiter属性)
15,delimitAllColumns:设置是否所有生成的SQL中的列名都使用标识符引起来。默认为false,delimitIdentifiers参考context的属性
注意,table里面很多参数都是对javaModelGenerator,context等元素的默认属性的一个复写;-->
<table tableName="t_user">
<generatedKey column="id" sqlStatement="Mysql" identity="true"/>
</table> </context>
</generatorConfiguration>

假设产生此错误:

 [ERROR] Failed to execute goal org.mybatis.generator:mybatis-generator-maven-plugin:1.3.5:generate (default-cli) on project edu: XML Parser Error on line 60: 元素类型为 "context" 的内容必须匹配 "(property*,plugin*,commentGenerator?,(connectionFactory|jdbcConnection),javaTypeResolver?,javaModelGenerator,sqlMapGenerator?,javaClientGenerator?,table+)"。 -> [Help 1]

原因就是:generate中,标签都是有顺序的,此类错误就是标签的顺序存在问题

此时,xml文件以及配置结束,需要在idea中配置启动操作:mybatis-generator:generate,如图

Spring boot入门(三):SpringBoot集成结合AdminLTE(Freemarker),利用generate自动生成代码,利用DataTable和PageHelper进行分页显示

(4)DataTable的使用

DataTable是一款简单易用的分页插件,基于JQuery写的,里面提供了丰富的分页参数,主要通过Ajax实现数据的前后端传输

首先引入js和css包:

<link rel="stylesheet" href="https://cdn.datatables.net/1.10.16/css/jquery.dataTables.min.css" />

<script src="https://cdn.datatables.net/1.10.16/js/jquery.dataTables.min.js"></script>

其外,还需要格式化相关提示文字,一般命名为:language.json

 {
"sEmptyTable": "没有相关数据",
"sInfo": "从 _START_ 到 _END_ 条记录 总记录数为 _TOTAL_ 条",
"sInfoEmpty": "记录数为0",
"sInfoFiltered": "(全部记录数 _MAX_ 条)",
"sInfoPostFix": "",
"sInfoThousands": ",",
"sLengthMenu": "显示 _MENU_ 条",
"sLoadingRecords": "正在加载...",
"sProcessing": "正在获取数据,请稍候...",
"sSearch": "搜索",
"sZeroRecords": "没有您要搜索的内容",
"oPaginate": {
"sFirst": "首页",
"sPrevious": "上一页",
"sNext": "下一页",
"sLast": "尾页",
"sJump": "跳转"
},
"oAria": {
"sSortAscending": ": 以升序排序",
"sSortDescending": ": 以降序排序"
}
}

具体的实现方式如下代码:

 var user_tab;
var user_list_param;
$(function () {
var url="/admin/user/listPage";
user_list_setParm();
user_tab = $('#user_tab').DataTable({
"fnDrawCallback": function () {
},
"dom": '<"top"i>rt<"bottom"flp><"clear">',
//"ordering":false,//是否排序
"processing": true,
"searching": false,
"serverSide": true, //启用服务器端分页
"order": [[ 5, "asc" ]],//默认排序字段
"bInfo": true,
"bAutoWidth": false,
"scrollX": true,
"scrollCollapse": false,
/*fixedColumns: {
leftColumns: 0,
rightColumns: 1
},*/
"language":{"url":"/plugins/datatables/language.json"},
"ajax":{"url":url,"data":user_list_param,"type":"post"},
"columns":[
{"data":"id"},
{"data":null},
{"data":"userName"},
{"data":"password"},
{"data":"trueName"},
{"data":"createTime"},
{"data":"id"}
],
"columnDefs" : [
{
targets: 0,
data: null,
orderable:false,
render: function (data) {
return '<input type="checkbox" class="userCheckbox" value="'+data+'"/>';
}
},
{
targets: 1,
data: null,
orderable:false,
render: function (data) {
No=No+1;
return No;
}
},
{
"targets" : -1,
"data" : null,
orderable:false,
"render" : function(data) {
var data = "'"+data+"'";
var btn1='<a class="btn btn-xs btn-warning" target="modal" modal="hg" href=""><i class="fa fa-edit"></i>修改</a> &nbsp;';
var btn2 = '<a class="btn btn-xs btn-danger" target="modal" modal="hg" onclick="user_list_delete('+data+')"><i class="fa fa-remove"></i>删除</a> &nbsp;';
return btn1+btn2;
}
}
]
}).on('preXhr.dt', function ( e, settings, data ) {
No=0;
}).on('xhr.dt', function(e, settings, json, xhr) {
});
});

这里面需要说明的:

a.如果开启排序,那么后端接受参数的方式:

@RequestParam(value = "order[0][column]", required = false) Integer orderIndex
@RequestParam(value = "order[0][dir]", required = false) String orderDir
其中orderIndex为排序的字段,而orderDir为排序的方式(升序或者降序)。orderIndex中是前端table中字段的列号,所以通畅,还需要在后台初始化一个数组,然后再数组中取实际需要排序的字段,例如:
   String[] cols = {"", "", "user_name", "password", "true_name", "create_time"};
Result<Page<TUser>> result = userService.listPage((start / pageSize) + 1, pageSize, cols[orderIndex], orderDir);

b.一般在对列表进行了增删改查后,需要重新刷新列表,而此时,大多数情况下,想列表保持当前页面刷新,那么需要使用函数

user_tab.draw(false);
其中user_tab为table的JQuery对象,如果不需要保持此页面,去掉false即可。

c.需要冻结某列的时候,需要使用到fixedColumns函数,可以使用on进行函数回调,使用dom,进行页面统计文字的显示位置"dom": '<"top"i>rt<"bottom"flp><"clear">',

(5)PageHelper后台分页的编写

  public Result<Page<TUser>> listPage(int pageCurrent, int pageSize, String userName, String trueName, String cols, String orderDir) {
Example example = new Example(TUser.class);
Criteria criteria = example.createCriteria();
ExampleUtils.getLikeExample(criteria, "userName", userName);
ExampleUtils.getLikeExample(criteria, "trueName", trueName);
example.setOrderByClause(cols + " " + orderDir);
//example.orderBy(cols+" "+orderDir);
Result<Page<TUser>> result = new Result<Page<TUser>>();
PageHelper.startPage(pageCurrent, pageSize);
List<TUser> tUsers = userMapper.selectByExample(example);
PageInfo<TUser> pageInfo = new PageInfo<TUser>(tUsers, pageSize);
Page<TUser> resultData = new Page<TUser>((int) pageInfo.getTotal(), pageInfo.getPages(), pageCurrent, pageSize, tUsers);
result.setResultData(resultData);
result.setErrCode(0);
result.setStatus(true);
return result;
}

由于,需要配个DataTable,所以需要重新编写page类,保证字段的一致性,这里就放弃了PageHelper自带的PageInfo,实际上,这2个类中,字段类型基本一致,区别不大。
