Spring Boot项目中使用jdbctemplate 操作MYSQL数据库

不废话，先来代码

pom文件：

<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">

	    <version>5.1.21</version>
	 </dependency>

  </dependencies>
</project>

　　配置文件：application.properties（springboot框架默认使用这个名字，放在resources下面）

spring.datasource.url=jdbc:mysql://localhost:3306/service_lucky_draw?autoReconnect=true&useUnicode=true&characterEncoding=utf-8
spring.datasource.username=root
spring.datasource.password=1234
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

spring.application.name = @pom.artifactId@
server.port=33333

　　启动类：

package versionUpdate;

import java.util.List;
import java.util.Map;

import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.jdbc.core.JdbcTemplate;

@SpringBootApplication
public class ApplicationMain implements CommandLineRunner {
	private Logger log = Logger.getLogger(ApplicationMain.class);

	@Autowired
	private JdbcTemplate jdbcTemplate;

	public static void main(String[] args) {
		SpringApplication springApplication = new SpringApplication(ApplicationMain.class);
		springApplication.run(args);
	}

	@Override
	public void run(String... args) throws Exception {
		String queryMerchandiseInfoSql = "SELECT id,worth,channel_id,template_id FROM merchandise_info";
		List<Map<String, Object>> list = jdbcTemplate.queryForList(queryMerchandiseInfoSql);
		log.debug(list);
	}
}

　　至此一个简单的SpringBoot+Jdbctemplate+MYSQL的DEMO搭建完成；

如果不想在启动类里面直接进行数据库操作，可以按照下面的方式：

package versionUpdate;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Component;

/** 获取jdbctemplate实例 */
@Component
public class EnterJdbcTemplate {

	private static JdbcTemplate jdbcTemplate;

	@Autowired
	public EnterJdbcTemplate(JdbcTemplate jdbcTemplate) {
		this.jdbcTemplate = jdbcTemplate;
	}

	public static JdbcTemplate getJdbcTemplate(){
		return jdbcTemplate;
	}

}

　　

package versionUpdate;

import org.springframework.jdbc.core.JdbcTemplate;

/** 操作数据库 */
public class Movedata extends EnterJdbcTemplate{

	public Movedata(JdbcTemplate jdbcTemplate) {
		super(jdbcTemplate);
	}

	public static void ccc(){
		System.out.println("++++++++++++++++++"+getJdbcTemplate().queryForMap("SELECT * FROM channel_info WHERE channel_id = ? ","cccc"));
	}
}
