Error creating bean with name ‘xxx‘ defined in javaconfig问题。

作为一个Spring的初学者,检查过文件的配置,全部都是正确的,但是不知道为什么我已启动就是Error creating bean with name 'xxx' defined in javaconfig问题。直接上代码,求大神指点。

这是我的项目结构:

这是我引入的依赖:



    4.0.0

    com.hncgzy.wutao
    day02_spring_04
    1.0-SNAPSHOT

    
        UTF-8
        1.8
        1.8
        
        5.0.2.RELEASE
        
        1.6.6
        1.2.12
        
        8.0.13
        
        3.5.3

        
        4.12

        
        1.18.8

        
        1.3.0
    
    
        
        
            org.springframework
            spring-context
            ${spring.version}
        

        
            junit
            junit
            ${junit.version}
            test
        
        
            org.projectlombok
            lombok
            ${lombok.version}
        
        
        
            mysql
            mysql-connector-java
            ${mysql.version}
        

        
        
            org.mybatis
            mybatis
            ${mybatis.version}
        
        
        
            org.mybatis
            mybatis-spring
            ${mybatis.spring.version}
        

        
        
            log4j
            log4j
            ${log4j.version}
        

        
            org.slf4j
            slf4j-api
            ${slf4j.version}
        

        
            org.slf4j
            slf4j-log4j12
            ${slf4j.version}
        
        
        
            org.springframework
            spring-jdbc
            ${spring.version}
        
    

持久层和业务层就是一些简单的增删改查:

@Controller
public class  AccountController {
    @Autowired
    private AccountService accountService;

    public List findAll() throws SQLException {
        return accountService.findAll();
    }

    public Account findById(int id) throws SQLException {
        return accountService.findById(id);
    }

    public void deleteById(int id) throws SQLException {
        accountService.deleteById(id);
    }

    public void add(Account account) throws SQLException {
        accountService.add(account);
    }

    public void update(Account account) throws SQLException {
        accountService.update(account);
    }
}
public interface AccountService {
    //查询所有账号信息
    List findAll() throws SQLException;

    //根据id查询账号信息
    Account findById(int id) throws SQLException;

    //根据id删除账号信息
    void deleteById(int id) throws SQLException;

    //添加账号信息
    void add(Account account) throws SQLException;

    //修改账号信息
    void update(Account account) throws SQLException;
}

 这是config层用来替代applicationContext.xml

@Configuration
@ComponentScan(basePackages = "com.hncgzy")
@import(MybatisConfig.class)

public class SpringConfig {


}
@PropertySource("classpath:mybatis.properties")
public class MybatisConfig {
    @Value("${mybatis.username}")
    private String username;

    @Value("${mybatis.password}")
    private String password;

    @Value("${mybatis.url}")
    private String url;

    @Value("${mybatis.driver}")
    private String driver;

    @Value("${mybatis.typeAliases.package}")
    private String typeAliasesPackage;

    @Value("${mybatis.mapper.package}")
    private String mapperPackage;

    @Bean
    public DataSource getDataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setUsername(username);
        dataSource.setPassword(password);
        dataSource.setUrl(url);
        dataSource.setDriverClassName(driver);
        return dataSource;
    }

    @Bean
    public SqlSessionFactoryBean getSqlSessionFactoryBean(DataSource dataSource){
        SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();

        sqlSessionFactoryBean.setDataSource(dataSource);
        sqlSessionFactoryBean.setTypeAliasesPackage(typeAliasesPackage);
        return sqlSessionFactoryBean;
    }

    @Bean
    public MapperScannerConfigurer getMapperScannerConfigurer(){
        MapperScannerConfigurer mapperScannerConfigurer = new MapperScannerConfigurer();
        mapperScannerConfigurer.setbasePackage(mapperPackage);
        return mapperScannerConfigurer;
    }
}

这是sql语句:




    
        select *
        from account
        where id = #{id}
    

    
        delete
        from account
        where id = #{id}
    

    
        inner into account(name,money) values (
        #{name},
        #{money}
        )
    

    
        update account
        set name = #{name},
            money=#{money}
        where id = #{id}
    

这是错误原因:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'getMapperScannerConfigurer' defined in com.hncgzy.config.MybatisConfig: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Property 'basePackage' is required

求大神指点。owo
