Springboot接口简单实现调用接口生成MySQL插入语句
在实际测试中,有这样一个需求场景,比如:在性能压力测试中,可能需要我们事先插入数据库中一些相关联的数据。
我们在实际测试中,遇到问题,需要事先在数据库中创建10000家门店,存在shop表中。关键字段(门店的编号6位数)。
分析:两种具体实现方案。
一、利用MySQL函数功能随机生成<SELECT FLOOR(+ RAND() * 1000000)>,最后编写insert语句。但是效率低下。
二、使用springboot编写接口实现,并自动生成insert脚本保存本地。
本次实现以springboot接口实现此次目的:
- 开发环境
- 开发工具IDEA
- JDK 1.8
- 新建springboot项目
1、新建project
2、填写springbootDemo
直到填写finish完成。
? ?3、pom.xml文件配置
<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.1.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.springbootDemo</groupId> <artifactId>demo</artifactId> <version>0.0.1-SNAPSHOT</version> <name>demo</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.16.14</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
?
4、打开工程,看到main里面有默认启动类。
@RestController@SpringBootApplicationpublic class DemoApplication { public static void main(String[] args) { SpringApplication.run(DemoApplication.class, args); } }
- 编写接口实现类
* 分析:* inpuid: uuid* sotreId=commonCode 以8开头后面五位随机* createDatetime:当前时间* create_by: admin* is_recharge_consumption:1* updateDatetime:当前时间* update_by:admin* sync_date:null* channel_key:123456* chainName: XX* state:0* shopCode 以8开头后面五位随机
@RequestMapping("/generateSql") public static String insert(@RequestParam(required = false) int size) throws IOException { // 开时时间 Long begin = new Date().getTime(); log.info("begin:{}",begin); for (int i = 0; i <size ; i++) { StringBuffer addSql = new StringBuffer(); SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); addSql.append("INSERT INTO" + " t_shop" + "(`inputId`, `storeId`, `storeType`, `initialsName`, `storeName`, `ipAddress`, `portEP`, `ipAddressEP`, `fixedTelephone`, `mobile`, `contactPerson`, `email`, `address`, `registrationNo`, `createDatetime`, `create_by`, `is_recharge_consumption`, `updateDatetime`, `update_by`, `sync_date`, `channel_key`, `chainName`, `state`, `commonCode`, `areaCode`, `registNumberEP`, `softName`, `busiNature`, `brand`, `floor`, `usageArea`, `computerNum`, `profit_rate`)"); addSql.append("values" + "("); addSql.append("‘"+UUID.randomUUID().toString().replace("-", "") + "‘,"); //生成commoncode storeid String newStoreId; double a = (Math.random()+1)*1000; int sotreId = Integer.parseInt(String.valueOf(a).substring(0,4)); newStoreId = "‘8" + String.valueOf(sotreId) + "‘"; addSql.append(newStoreId + ",");// String empty = "".join("‘", Collections.nCopies(12,"‘,")); String empty = "‘‘,"; addSql.append(empty); addSql.append(empty); addSql.append(newStoreId + ","); addSql.append(empty); addSql.append(empty); addSql.append(empty); addSql.append(empty); addSql.append(empty); addSql.append(empty); addSql.append(empty); addSql.append(empty); addSql.append(empty); Date date = new Date(); SimpleDateFormat sdf1 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); String createTime = sdf1.format(date); addSql.append("‘"+createTime + "‘,"); addSql.append("‘admin‘,"); addSql.append("‘1‘,"); addSql.append("‘"+createTime + "‘,"); addSql.append("‘admin‘,"); addSql.append(NULL + ","); addSql.append("‘123456‘,"); addSql.append("‘XX‘,"); addSql.append("‘0‘,"); addSql.append(newStoreId + ","); addSql.append(empty); addSql.append("‘201805093512‘,"); addSql.append(empty); addSql.append(empty); addSql.append(empty); addSql.append(empty); addSql.append(NULL + ","); addSql.append(NULL + ","); addSql.append(NULL); addSql.append(");"); String path = "D:\\sqlYpay.txt"; BufferedWriter out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(path,true))); out.write(addSql+"\r\n"); System.out.println(addSql); out.close(); }// System.out.println(addSql); // 结束时间 Long end = new Date().getTime(); log.info("end:{}",end); log.info("耗时:{}",end-begin); // 耗时 System.out.println("cast : " + (end - begin) / 1000 + " s"); return "生成SQL执行语句成功,一共生成了:>>>>>>" + size; }
- 启动主程序,调用接口
?SQL语句生成执行成功,查看文件夹生成文件。执行即可。
