Field baseMapper in xxxxx required a bean of type 'xxxxxx' that could not be found 问题

最近在整合spring boot 和通用mapper时遇到错误，纠结了好长时间，先看错误

Description:Field baseMapper in com.sinosoft.common.mybatis.service.impl.BaseServiceImpl required a bean of type 'com.sinosoft.common.mybatis.mapper.MyBaseMapper' that could not be found.Action:Consider defining a bean of type 'com.sinosoft.common.mybatis.mapper.MyBaseMapper' in your configuration.Process finished with exit code 1

问题解决思路
1.先看下pom，下边是整合通用mapper所须的依赖

 <!--mysql--><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId></dependency><!--mybatis--><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>1.3.0</version></dependency><!-- pagehelper分页插件 --><dependency><groupId>com.github.pagehelper</groupId><artifactId>pagehelper-spring-boot-starter</artifactId><version>1.2.3</version></dependency><!-- 通用mapper --><dependency><groupId>tk.mybatis</groupId><artifactId>mapper-spring-boot-starter</artifactId><version>2.0.2</version></dependency><!-- 阿里巴巴druid数据库连接池 非必须 --><dependency><groupId>com.alibaba</groupId><artifactId>druid</artifactId><version>1.0.18</version></dependency>

2.代码目录结构

3.需要检查的点
3.1basemapper 不能和业务类的mapper放在同一目录下

3.2service实现类应该抽象的避免被通用mapper扫描

public abstract class BaseServiceImpl<T,ID extends Serializable> implements BaseService<T,ID> {@Autowiredpublic MyBaseMapper<T> baseMapper;

3.3业务类mapper应该加上@Mapper注解，或者在spring boot启动类上添加@MapperScan注解

@Mapper
public interface MusicMapper extends MyBaseMapper<MusicModel> {}

@SpringBootApplication
@MapperScan(basePackages ={"com.sinosoft.musicproxy.mapper"})
public class MusicProxyApplication  {public static void main(String[] args) {SpringApplication.run(MusicProxyApplication.class, args);}
}

3.4业务类应该继承你自己的通用mapper接口。我自己的错误就是吧MyBaseMapper写成了BaseMapper（这个错误是真的低级）

//错误
@Mapper
public interface MusicMapper extends BaseMapper<MusicModel> {}//正确
@Mapper
public interface MusicMapper extends MyBaseMapper<MusicModel> {}

3.5namespace对应接口名

<mapper namespace="com.sinosoft.musicproxy.mapper.MusicMapper" >

package com.sinosoft.musicproxy.mapper;/*** @author fxl* @Title: ${file_name}* @Package ${package_name}* @Description: ${todo}* @date 2018-06-149:55*/
@Mapper
public interface MusicMapper extends BaseMapper<MusicModel> {}

3.6.还有可能是你的某些mapper没有加@mapper注解，也会出现这种情况
这算我在遇到这个问题在网上找到解决方法吧，希望别有人跟我一样犯同样的错误，特别是低级错误。写的不好，见谅。
