关于spring中测试

1.首先导入相应的jar包

    org.springframework
    spring-test
    5.3.13

    junit
    junit
    4.12
    test

2.需要相应的注解

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext.xml")
public class Test02 {
    @Autowired   //注入相应的对象
    private JdbcTemplate jdbcTemplate;
    @Test
    public void m1(){
        int i = jdbcTemplate.update("update user set name = ? where id = ?", "小明", 15);
        System.out.println(i);
    }

}

关于@ConbtextConfiguration()中路径配置问题
(1) @ContextConfiguration(value="/applicationContext.xml")
(2)@ContextConfiguration(location="/applicationContext.xml")
(3)@ContextConfiguration("classpath:applicationContext.xml")
(4)@ContextConfiguration("/applicationContext.xml")
