db-exchange

数据库分批读写交互模板

功能

• 封装数据分批流式读写模板
• 封装mysql, es和mongo数据库的读写模板

模块

• db-exchange-core：核心读写交互模板
• db-exchange-mysql：封装mysql数据库读写
• db-exchange-es：封装es数据库读写
• db-exchange-mongo：封装mongo数据库读写
• db-exchange-spring-jdbc：封装Spring JDBC读写

快速开始

1. 添加db-exchange-mysql Maven引用

           <dependency>
               <groupId>com.github.mengzuozhu</groupId>
               <artifactId>db-exchange-mysql</artifactId>
               <version>1.0.1</version>
           </dependency>

2. mysql读取示例

   public class ExchangeDemo {
   
       public static void main(String[] args) {
           String url = "jdbc:mysql://localhost:3306/test?characterEncoding=utf8&serverTimezone=Asia/Shanghai";
           DataSource dataSource = MysqlUtil.getDataSource(url, "root", "your mysql password");
           MysqlQuery query = MysqlQuery.builder()
                   .dataSource(dataSource)
                   .sql("SELECT * FROM user")
                   .batchSize(100)
                   .build();
           DataReader<Map<String, Object>> mysqlDataReader = new MysqlDataReader<>(query, new ResultSetToMap());
           ListDataCollector<Map<String, Object>> listDataCollector = new ListDataCollector<>();
           ExchangeTemplate.from(mysqlDataReader)
                   .execute(listDataCollector)
                   .await();
           // do something
           List<Map<String, Object>> result = listDataCollector.getResult();
       }
   }
