mybatis报错invalid types () or values ()解决方法
报错信息：
org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.reflection.ReflectionException: Error instantiating class com.huawei.mon.tools.DB.bean.table.T_contactList with invalid types () or values (). Cause: java.lang.NoSuchMethodException: com.huawei.mon.tools.DB.bean.table.T_contactList.&init&()
1） model中的get/set方法与成员变量不一。
2） 构造函数被重载过，但是没有空的构造函数。
3） 最好不要使用简单类型，如int, long等，改用对象模式Integer, Long等。在写条件查询时会用到判断&if xxx != null & … &/if&的

me.gacl.domain.User
请问你说的是哪里？是映射文件吗？
TypeException: Could not resolve type alias 'me.gacl.domain.User'. Cause: java.lang.ClassNotFoundException: Cannot find class: me.gacl.domain.User
类型错误，首先，确定me.gacl.domain.User
这个类是否存在，路径是否正确。如果前面还没解决 看下面：
不知道你的是输入参数的类型错误还是输出的参数错误，
建议：如果是输入参数，就一个一个设置输入参数类型：例如：values (#{code,jdbcType=VARCHAR}, #{franchiserId,jdbcType=INTEGER}, #{useFlag,jdbcType=INTEGER},
如果是输出参数：那么你查询出来的每列名字和你的类属性名字要一样，区分大小写。
A as 类的属性名
类的属性名
配置文件写的有问题吧，，，
