springboot+jdbcTemplate+sqlite编程示例——以沪深300成分股数据处理为例
2023-12-13 11:37:31
引言
我们在自己做一些小的项目或者小的数据处理分析的时候，很多时候是不需要用到mysql这样的大型数据库，并且也不需要用到maven这样很重的框架的，取而代之可以使用jdbcTemplate+sqlite这样的组合。
本文就介绍一下使用springboot+jdbcTemplate+sqlite编程的方法，本文会以处理沪深300成分股数据为例。
数据源
首先介绍一下本文进行数据处理的结果，我们最后会获得沪深300成分股列表，包括每一只股票的代码，名称，所述行业以及权重，最后处理的结果如下图所示
我们的数据源主要来自中证指数官网，有两个数据源，分别是沪深300权重列表和行业分类表
沪深300指数-中证指数有限公司 (csindex.com.cn)
行业分类查询-中证指数有限公司 (csindex.com.cn)?
综合这两张表就可得到沪深300成分股的权重占比以及所属行业信息了
数据库初始化
本文使用的sqlite数据库可以说是一个嵌入式数据库，几乎没有依赖，我们只需要在项目中引入sqlite-jdbc就行了
<dependency>
<groupId>org.xerial</groupId>
<artifactId>sqlite-jdbc</artifactId>
<version>3.36.0</version>
</dependency>当我们引入sqlite-jdbc之后，可以在依赖包中看到数据库实例，我们不需要自己再去安装数据库
这个数据库的所有信息都会保存在一个db文件里，我们可以在项目的资源目录中创建这个db文件
?
然后在application.properties配置文件中指定该db文件，由于数据库是本地的，所以连用户名和密码都不用，不过在性能上好像会比mysql慢一点，不过这么方便，而且几乎没有依赖的数据库还要什么自行车呢，对于自己做一些小玩具完全是够用了。
spring.datasource.url=jdbc:sqlite:file:src/main/resources/database.db数据处理
我们进行数据处理的时候主要是处理excel信息，这里会用到hutool工具包以及poi，需要引入如下依赖
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>5.0.0</version>
</dependency>
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>5.0.0</version>
</dependency>
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml-full</artifactId>
<version>5.0.0</version>
</dependency>
<dependency>
<groupId>cn.hutool</groupId>
<artifactId>hutool-all</artifactId>
<version>5.7.15</version>
</dependency>我们主要获取以下几个维度的数据
@Data
@AllArgsConstructor
@NoArgsConstructor
public class CSI300Entity {
private Integer id;
private String code;
private String name;
private String industry;
private Double weight;
}?我们把所有的数据处理都写到一个类里，包括创建表，插入数据和查询所有数据
@Slf4j
@Repository
public class SQLIteCSI300Dao implements CSI300Dao{
private final String tableName = "csi_300";
@Autowired
private JdbcTemplate jdbcTemplate;
@Override
public void createTableIfNotExist() {
Integer count = jdbcTemplate.queryForObject("SELECT COUNT(*) FROM sqlite_master WHERE type='table' AND name=?", Integer.class, tableName);
if (count == 0) {
String sql = "create table " + tableName + "(" +
"id INTEGER PRIMARY KEY AUTOINCREMENT," +
"code VARCHAR(20)," +
"name VARCHAR(20)," +
"industry VARCHAR(20)," +
"weight float)";
jdbcTemplate.execute(sql);
log.info(tableName + "建表成功");
} else {
log.info(tableName + "表已经存在，无需创建");
}
}
@Override
public int insertOneItem(CSI300Entity entity) {
String sql = "INSERT INTO " + tableName +
"(code, name, industry, weight) VALUES " +
"(?, ?, ?, ?)";
Object[] params = new Object[] {
entity.getCode(),
entity.getName(),
entity.getIndustry(),
entity.getWeight()
};
int num = jdbcTemplate.update(sql, params);
StringBuilder sb = new StringBuilder();
sb.append("执行" + sql);
sb.append("=>[");
for (int i=0; i<params.length; i++) {
sb.append(params[i].toString());
if (i != params.length-1) {
sb.append(", ");
}
}
sb.append("]");
if(num == 0) {
log.error(sb.toString() + "失败");
} else {
log.info(sb.toString() + "成功");
}
return num;
}
@Override
public List<CSI300Entity> queryAllItems() {
String sql = "SELECT * FROM " + tableName;
List<CSI300Entity> csi300Entities = jdbcTemplate.query(sql, new Object[]{}, new BeanPropertyRowMapper<CSI300Entity>(CSI300Entity.class));
return csi300Entities;
}
}
然后是解析excel表格汇总数据
@Slf4j
@Service
public class CSI300Service {
private final String FILE_PATH_WEIGHT = "E:/数据可视化工具/data_cat/数据/000300closeweight.xls";
private final String FILE_PATH_INDUSTRY = "E:/数据可视化工具/data_cat/数据/行业分类.xlsx";
private List<CSI300Entity> csi300EntityList;
@Autowired
private SQLIteCSI300Dao sqlIteCSI300Dao;
// 通过解析excel获取信息
public void parseExcel() {
ExcelReader excelReader = ExcelUtil.getReader(FILE_PATH_WEIGHT);
excelReader.addHeaderAlias("成份券代码Constituent Code", "code");
excelReader.addHeaderAlias("成份券名称Constituent Name", "name");
excelReader.addHeaderAlias("权重(%)weight", "weight");
csi300EntityList = excelReader.readAll(CSI300Entity.class);
log.info("成功解析出" + csi300EntityList.size() + "条数据");
log.info("开始解析所属行业");
excelReader = ExcelUtil.getReader(FILE_PATH_INDUSTRY);
excelReader.addHeaderAlias("证券代码", "code");
excelReader.addHeaderAlias("证监会行业门类简称", "industry");
List<CSI300Entity> csi300Entities = excelReader.readAll(CSI300Entity.class);
for(int i=0; i<csi300Entities.size(); i++) {
for(int j=0; j<csi300EntityList.size(); j++) {
if (csi300EntityList.get(j).getCode().equals(csi300Entities.get(i).getCode())) {
csi300EntityList.get(j).setIndustry(csi300Entities.get(i).getIndustry());
}
}
}
for(int i=0; i<csi300EntityList.size(); i++) {
log.info(csi300EntityList.get(i).toString());
sqlIteCSI300Dao.insertOneItem(csi300EntityList.get(i));
}
}
}最后看一下控制层，在编写控制层的时候加上@CrossOrigin表示这个类的所有接口都是允许跨域请求的
@Controller
@CrossOrigin
public class CSI300Controller {
@Autowired
private SQLIteCSI300Dao sqlIteCSI300Dao;
@Autowired
private CSI300Service csi300Service;
@RequestMapping("/createTable")
@ResponseBody
public String createTable() {
sqlIteCSI300Dao.createTableIfNotExist();
return "success";
}
@RequestMapping("/parse")
@ResponseBody
public String parse() {
csi300Service.parseExcel();
return "success";
}
@RequestMapping("/queryAll")
@ResponseBody
public String queryAll() {
List<CSI300Entity> csi300Entities = sqlIteCSI300Dao.queryAllItems();
return JSON.toJSONString(csi300Entities);
}
}由于数据量不大，这里就将所有的数据展示出来，大家有需要可以自取

最后是用vue+element-plus编写一个简单的前端页面展示数据，页面非常简单，就是使用axios接收数据，然后渲染到表格中
<template>
<el-row>
<el-col :span="12">
<el-card>
<el-table
:data="table_data"
:show-header="true"
:max-height="635"
stripe
>
<el-table-column prop="id" label="序号"></el-table-column>
<el-table-column prop="code" label="股票代码"></el-table-column>
<el-table-column prop="name" label="公司简称"></el-table-column>
<el-table-column prop="industry" label="所属行业"></el-table-column>
<el-table-column prop="weight" label="权重占比"></el-table-column>
</el-table>
</el-card>
</el-col>
<el-col :span="12"> </el-col>
</el-row>
</template>
<script>
import axios from "axios";
export default {
data() {
return {
table_data: [],
};
},
mounted() {
this.init();
},
methods: {
init() {
var url = "http://localhost:9001/queryAll";
axios
.get(url)
.then((response) => {
this.table_data = response.data;
console.log(response);
})
.catch(function (error) {
console.log(error);
});
},
},
};
</script>
<style scoped></style>
最后展示的效果就如文章开头那样。
结语
本文介绍了使用springboot+jdbcTemplate+sqlite进行编程的用例，并且以处理沪深300成分股数据为例子，我觉得如果我们自己写一些小玩具的话，这样的组合会比较好一点。
那么本文内容就到此结束啦，有什么想和我讨论的欢迎评论区留言。
