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<SysUser> sysUsers = mapper.queryCustomer2(list);
for (SysUser sysUser : sysUsers) {
System.out.println(sysUser);
}
}
