SpringBoot整合JdbcTemplate连接Mysql

import java.io.IOException;

import javax.sql.DataSource;

import org.apache.ignite.IgniteSystemProperties;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.ImportAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.datasource.DriverManagerDataSource;


@SpringBootApplication
public class Application {

    public static void main(String[] args) throws IOException {
        

        SpringApplication.run(Application.class, args);
    }

    @Bean
    public JdbcTemplate jdbcTemplate() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName("com.mysql.jdbc.Driver");
        dataSource.setUrl("jdbc:mysql://127.0.0.1:3306/test");
        dataSource.setUsername("root");
        dataSource.setPassword("123456");

        JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);
        return jdbcTemplate;
    }

}

添加依赖：

apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

springBoot {
executable = true
mainClass = 'com.test.Application'
}

dependencies {
compile "org.springframework.boot:spring-boot-starter-web:${verSpringBoot}"

compile "mysql:mysql-connector-java:5.1.21"

}
