SpringBoot 整合MybatisPlus mapper 注入失败的问题
描述
这个问题出现之后反复的校验配置文件是否配置了 xml 文件的加载，，mapper 映射文件的位置，
都是对的，也百度了，没有找到正确的解决方式多是说 xml文件的位置，@MapperScan 等问题，
其实，是因为搜索的方式错了。。。

测试代码调用才产生的问题
@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = WlqkApplication.class)
public class Demo {
@Autowired
private SysUserMapper sysUserMapper;
@Test
public void test1(){
System.out.println(sysUserMapper.selectList(null));
}
}
mapper 文件
/**

* Mapper 接口

*/
public interface SysUserMapper extends BaseMapper {
}
解决方式
mapper 映射文件加上 @Mapper 注解
/**
*
* Mapper 接口
*
*
* @author zc
* @since 2019-07-06
*/
@Mapper
public interface SysUserMapper extends BaseMapper {
}
