1.书写jsp页面包括要显示的内容【people.jsp】
<!--
此处包括三个方面内容：
1.包含 文本输入框 查询按钮 查询结果显示位置 （paging）
2.包括对按钮（button）的操作
-->
<div>
<div class="m-b-md2">
<form class="form-inline" id="searchForm2"
name="searchForm2">
<div class="form-group">
<div class="padding">
<span class="h4">人员最近事件查询:</span> <input class="input-medium" id="author" name="author">
</div>
</div>
<a href="javascript:void(0)" class="btn btn-info" id="search2">查询</a>
</form>
</div>
<div class="doc-buttons" style="padding: 10px 0">
<c:forEach items="${res}" var="key">
<button type="button" id="${fn:split(key.btn,',')[0]}" name="${fn:split(key.btn,',')[1]}" class="${fn:split(key.btn,',')[2]}">${fn:split(key.btn,',')[3]}</button>
</c:forEach>
</div>
<div id="paging2" class="pagclass2"></div>
</div>
2.新建查询操作的实体类 entity 放在entity包中【PeopleForMap.java】
/**
*此处包括要访问数据库的表名 和表的主键 对数据库做映射
*/
@TableSeg(tableName = "test", id="id")
public class PeopleFormMap extends FormMap<String,Object>{
/**
*
*/
private static final long serialVersionUID = 1L;
}
3.新建Service层 service层主要包括对增删改查的实现【PeopleService.java】
public interface PeopleService extends BaseService{
}
4.新建Service的具体实现【PeopleServiceImpl.java】
@Service("peopleService")
public class PeopleServiceImpl extends BaseServiceImpl implements PeopleService{
}
5.新建Controller层 将service注入controller【PeopleController.java】
此处书写要调用PeopleService执行的具体操作
@Controller
@RequestMapping("/people")
public class PeopleController extends BaseController {
@Inject
private PeopleService peopleService;
@ResponseBody
@RequestMapping("peoplelist")
public String peoplelist(String txtSelect) throws Exception {
return Common.BACKGROUND_PATH+"/system/riskforcast/people";
}
@ResponseBody
@RequestMapping("/findPeopleEvents")
public PageView findPeopleEvents(){
Map<String,Object> result = new HashMap<>();
PeopleFormMap peopleFormMap = getFormMap(PeopleFormMap.class);
PageView pageView = getPageView(peopleFormMap);
peopleFormMap.put("paging2",pageView);
peopleFormMap.put("mapper_id", "PeopleService.findPeopleEvents"); //根据mapper_id执行mapper中id=findPeopleEvents的sql操作
List<PeopleFormMap> re = peopleService.findByPage(peopleFormMap); //通过peopleService中的findByPage实现数据库查询
pageView.setRecords(re);
//result.put("pageView",pageView);
return pageView;
}
6.新建mapper表 主要包括对数据库执行的Sql语句【people-mapper】
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="PeopleService">
<select id="findPeopleEvents" resultType="com.lanyuan.entity.PeopleFormMap">
select * from test
where author is not null and author != '' //查询test表中author字段不为空的所有数据
<if test="author != null and author != ''">
and author like '%${author}%'
</if>
</select>
</mapper>
7.书写js页面 【people.js】
<!-- js页面内容1.书写查询方法 并初始化 2.你要调用的sql语句路径 3.你想查询的字段
-->
$(document).ready(function() {
initEventList(); //初始化方法
function initEventList() {
grid = lyGrid({
pagId : 'paging2',
l_column : [
{
colkey : "author",
name :"事件传播者",
}, {
colkey : "page_title",
name : "文章标题"
}, {
colkey :"refer_url",
name :"转载路径"
}, {
colkey : "release_date",
name : "更新时间"
}
],
jsonUrl : rootPath + '/people/findPeopleEvents.shtml',
checkbox : true,
serNumber : true
});
$("#search2").click("click", function() {// 绑定查询按扭
var searchParams = $("#searchForm2").serializeJSON();// 初始化传参数
grid.setOptions({
data : searchParams
});
});
}
