mysql template_Spring Boot项目中使用jdbctemplate 操作MYSQL数据库

不废话,先来代码

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"));

}

}
