java 单元测试 对h2数据库数据清理方式

try{
      JdbcTemplate jdbcTemplate = 获取DataSource结构，反射或加载Bean等都可以，不要对业务代码侵入;
      Connection connection = jdbcTemplate.getDataSource().getConnection();//获取连接
      ResultSet tables = connection.getMetaData().getTables(null, null, null, new String[]{"TABLE"});//获取表名
      connection.close();//记得关闭连接，或者使用连接池
      while(tables.next()){
        //若是测试类的测试方法超过7,java.sql.Connection无法获取连接导致死循环
        jdbcTemplate.update("DELETE FROM " + tables.getObject("TABLE_NAME"));
        //spring-test-5.2.1.RELEASE-sources.jar!\org\springframework\test\jdbc\JdbcTestUtils.deleteFromTables如果使用了springtest可以代替使用该方法
      }
    } catch (SQLException e) {
      e.printStackTrace();
    }
