SpringBoot integration with mybatis service startup exception log
2019-09-18 19:52:17.270 WARN 8320 — [ restartedMain] ConfigServletWebServerApplicationContext : Exception encountered during context initialization – cancelling refresh attempt: org.springframework.beans.factory. BeanCreationException: Error creating bean with name ‘testDtoMapper’ defined in file [D:\workspace\xesWorkspace\xes\target\classes\com\xes\www\core\mapper\TestDtoMapper. class]: Cannot resolve reference to bean ‘sqlSessionFactoryBean’ while setting bean property ‘sqlSessionFactory’; nested exception is org.springframework.beans.factory. NoSuchBeanDefinitionException: No bean named ‘sqlSessionFactoryBean’ available
Check the code and the introduction of jar packages no problem, the problem is the database data source and sqlSessionFactory is not integrated into a piece
maven configuration
<!--spring boot Integrating mybatis dependencies-->

Mybatis configuration class
@Configuration
@MapperScan(basePackages = {
"com.xes.www.core.mapper"
}, sqlSessionFactoryRef = "sqlSessionFactoryBean")
public class MybatisConfiguration {
// Replaces the traditional datasource binding sqlSessionFactoryBean
@Bean
public SqlSessionFactoryBean sqlSessionFactoryBean(DataSource dataSource) {
SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
sqlSessionFactoryBean.setDataSource(dataSource);
return sqlSessionFactoryBean;
}
}
So here’s the traditional configuration which is configured through XML
< ! – let Spring manage SQLSessionFactory using MyBatis and Spring integration ->;
< bean id=”sqlSessionFactory” class=”org.mybatis.spring.SqlSessionFactoryBean”>
< ! — database connection pooling –>;
< property name=”dataSource” ref=”dataSource” />
< ! — Loading MyBatis global configuration file –>
< property name=”configLocation” value=”classpath:mybatis/SqlMapConfig.xml” />
< /bean>
out successfully
