Spring Boot中使用jdbctemplate 操作MYSQL数据库实例
最近在学习使用SpringBoot连接数据库,今天学习了使用jdbctemplate操作MYSQL数据库,下面就留个笔记
不废话,先来代码
pom文件:
4.0.0 test test 0.0.1-SNAPSHOT jar test http://maven.apache.org UTF-8 org.springframework.boot spring-boot-starter 1.4.2.RELEASE org.springframework.boot spring-boot-starter-jdbc 1.4.2.RELEASE mysql mysql-connector-java 5.1.21
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:
packageversionUpdate;
importjava.util.List;
importjava.util.Map;
importorg.apache.log4j.Logger;
importorg.springframework.beans.factory.annotation.Autowired;
importorg.springframework.boot.CommandLineRunner;
importorg.springframework.boot.SpringApplication;
importorg.springframework.boot.autoconfigure.SpringBootApplication;
importorg.springframework.jdbc.core.JdbcTemplate;
@SpringBootApplication
publicclassApplicationMainimplementsCommandLineRunner{
privateLoggerlog=Logger.getLogger(ApplicationMain.class);
@Autowired
privateJdbcTemplatejdbcTemplate;
publicstaticvoidmain(String[]args){
SpringApplicationspringApplication=newSpringApplication(ApplicationMain.class);
springApplication.run(args);
}
@Override
publicvoidrun(String...args)throwsException{
StringqueryMerchandiseInfoSql="SELECTid,worth,channel_id,template_idFROMmerchandise_info";
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:
packageversionUpdate;
importorg.springframework.beans.factory.annotation.Autowired;
importorg.springframework.jdbc.core.JdbcTemplate;
importorg.springframework.stereotype.Component;
/**获取jdbctemplate实例*/
@Component
publicclassEnterJdbcTemplate{
privatestaticJdbcTemplatejdbcTemplate;
@Autowired
publicEnterJdbcTemplate(JdbcTemplatejdbcTemplate){
this.jdbcTemplate=jdbcTemplate;
}
publicstaticJdbcTemplategetJdbcTemplate(){
returnjdbcTemplate;
}
}
packageversionUpdate;
importorg.springframework.jdbc.core.JdbcTemplate;
/**操作数据库*/
publicclassMovedataextendsEnterJdbcTemplate{
publicMovedata(JdbcTemplatejdbcTemplate){
super(jdbcTemplate);
}
publicstaticvoidccc(){
System.out.println("++++++++++++++++++"+getJdbcTemplate().queryForMap("SELECT*FROMchannel_infoWHEREchannel_id=?","cccc"));
}
}
