Spring连接数据库 之 execute() 执行SQL语句

1. pom文件中导入依赖

 <dependencies>
        <!--        spring-context的jar包-->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>5.2.5.RELEASE</version>
        </dependency>
        <!--        spring-core的jar包-->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>5.2.5.RELEASE</version>
        </dependency>
        <!--        spring-beans的jar包-->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-beans</artifactId>
            <version>5.2.5.RELEASE</version>
        </dependency>
        <!--        spring-expression的jar包-->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-expression</artifactId>
            <version>5.2.5.RELEASE</version>
        </dependency>
        <!--        commons.lggging的jar包-->
        <dependency>
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>
            <version>1.2</version>
        </dependency>
        <!--AOP所需要的两个依赖-->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-aspects</artifactId>
            <version>5.2.5.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjweaver</artifactId>
            <version>1.9.5</version>
        </dependency>
        <!--jdbc的依赖-->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jdbc</artifactId>
            <version>5.2.5.RELEASE</version>
        </dependency>
        <!--MySQL的jar包-->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>8.0.19</version>
        </dependency>
        <!--Spring事务管理的jar包-->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-tx</artifactId>
            <version>5.2.5.RELEASE</version>
        </dependency>
    </dependencies>

2. 配置spring的xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

    <!--配置数据源-->
    <bean id="dataSource"
          class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <!--数据库驱动-->
        <property name="driverClassName" value="com.mysql.cj.jdbc.Driver"/>
        <!--连接数据库的url-->
        <property name="url" value="jdbc:mysql:///db_spring?serverTimezone=CTT"/>
        <!--连接数据库的用户名-->
        <property name="username" value="xxxxxx"/>
        <!--密码-->
        <property name="password" value="xxxxxx"/>
    </bean>

    <!--配置JDBC模板-->
    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
        <property name="dataSource" ref="dataSource"/>
    </bean>

</beans>

3. 进行测试：

public class Test {
    public static void main(String[] args) {
        ApplicationContext applicationContext =
                new ClassPathXmlApplicationContext("spring.xml");
        JdbcTemplate jdbcTemplate = (JdbcTemplate) applicationContext.getBean("jdbcTemplate");
        System.out.println(jdbcTemplate);
        jdbcTemplate.execute("create table user(" +
                "id int primary key auto_increment, " +
                "username varchar(40), " +
                "password varchar(40)" +
                ")");
    }
}

4. 观察是否创建表
