However, I Use manual mapper(#mapper comment) and model, It works
can be autowired
such as:
package com.steven.orm.client;
import java.util.List;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;
import com.steven.orm.model.ArthurDemo2;
#Mapper
public interface CustomArthurDemo2Mapper {
#Select("select * from arthur_demo2")
List<ArthurDemo2> selectAll();
}
I have configed mybatis locationmapper properties and sqlSessionFactoryBean
And this is my application.properties file:
##spring start port
server.port=8011
#database
spring.datasource.url=jdbc:mysql://10.110.0.83:3306/file?prepStmtCacheSize=512&cachePrepStmts=true&autoReconnect=true&characterEncoding=utf-8&allowMultiQueries=true
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
mybatis.mapper-locations=classpath*:mybatis/*.xml
This is sqlSessionFactory config bean
#Bean
public SqlSessionFactory sqlSessionFactory(DataSource dataSource) throws Exception{
SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
sqlSessionFactoryBean.setDataSource(dataSource);
sqlSessionFactoryBean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources(env.getProperty("mybatis.mapper-locations")));
return sqlSessionFactoryBean.getObject();
}
And this is my project structure:
This is my project git address:

please give me some help,thank you

I have fixed it myself. The mapper file is different from Spring MVC. It should be added #Mapper comment like following:
#Mapper
public interface MapperGeneratedByMybatis{
