测试

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:applicationContext.xml")
public class JdbcTemplateTest2 {

    @Autowired
    private JdbcTemplate jdbcTemplate;

    @Test
    public void test1() {

        // 使用JdbcTemplate来完成操作
        jdbcTemplate.execute("update t_user set sex='女'");// execute方法可以执行任意sql

    }
}
