SpringBoot集成mybatis服务启动异常日志

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

 检查代码和引入jar包没问题，问题原因是数据库datasource和sqlSessionFactory没有整合到一块

maven配置

<!--spring boot 整合 mybatis 依赖-->
<dependency>
   <groupId>org.mybatis.spring.boot</groupId>
   <artifactId>mybatis-spring-boot-starter</artifactId>
   <version>2.0.0</version>
</dependency>
<dependency>
   <groupId>org.mybatis</groupId>
   <artifactId>mybatis-spring</artifactId>
   <version>1.3.2</version>
</dependency>
<!-- 不需要引用下面这个jar包 https://mvnrepository/artifact/org.apache.ibatis/ibatis-core -->
<!--<dependency>
   <groupId>org.apache.ibatis</groupId>
   <artifactId>ibatis-core</artifactId>
   <version>3.0</version>
</dependency>-->

 Mybatis配置类

@Configuration
@MapperScan(basePackages = {
        "com.xes.www.core.mapper"
}, sqlSessionFactoryRef = "sqlSessionFactoryBean")
public class MybatisConfiguration {
    // 代替了传统的datasource绑定sqlSessionFactoryBean
    @Bean
    public SqlSessionFactoryBean sqlSessionFactoryBean(DataSource dataSource) {
        SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
        sqlSessionFactoryBean.setDataSource(dataSource);
        return sqlSessionFactoryBean;
    }
}

 下面是传统的配置也就是通过xml来配置的

<!-- 让spring管理sqlsessionfactory 使用mybatis和spring整合包中的 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 数据库连接池 -->
        <property name="dataSource" ref="dataSource" />
        <!-- 加载mybatis的全局配置文件 -->
        <property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml" />
    </bean>
