Parameter 'items' not found. Available parameters are [collection, list]

解决办法：，参数items 没有找到，可用参数 list,将items 修改成list这里才能接受得到controller 传过来的集合
1.在UserMapper里

2.在UserMapper.xml里

3.测试类

@Test
public void show() {
	SqlSession sqlSession = Util.opeSession();
	UserMapper mapper = sqlSession.getMapper(UserMapper.class);
	List list = new ArrayList();
	list.add(1);
	list.add(2);
	List sysUsers = mapper.queryCustomer2(list);
	for (SysUser sysUser : sysUsers) {
		System.out.println(sysUser);
	}
}
