引言

这个项目是我在4个月之前写的，今天突然兴起去测试了下项目是否能够运行，结果就报错了

遇到的问题

本来想在test包中去测试下数据库是否可以连接，结果运行的时候报错，导致我找错找了好久

  1. @Autowired
  2.     private DataSource dataSource;
  4.     @Test
  5.     public void test01() throws SQLException {
  7.         System.out.println("进入了sql判断方法");
  8.         System.out.println(dataSource.getConnection());
  9.     }

报错信息：

原因

因为我的项目中使用了@EnableWebMvc这个注解，才导致出的问题，具体原因我不太清楚

如何解决

删除掉@EnableWebMvc注解即可正常启动
