            <artifactId>spring-jdbc</artifactId>
            <version>5.0.5.RELEASE</version>
        </dependency>

<dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-tx</artifactId>
            <version>5.0.5.RELEASE</version>
        </dependency>

public void test5() throws Exception {
        //读取配置文件
        ApplicationContext app = new ClassPathXmlApplicationContext("applicationContext.xml");

        JdbcTemplate jdbcTemplate = (JdbcTemplate) app.getBean("jdbcTemplate");

        jdbcTemplate.update("insert into spring_user(user_name) value(?) ","李四");
