Spring Boot项目中使用jdbctemplate 操作MYSQL数据库

pom文件：

　　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> 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")); 
}
}
