spring boot使用JPA，不采用 继承，运行报错求大神指导

目录结构如上图所示，请问我应该怎么配置使用，扫描包需要配置子目录吗？
启动异常如下，求大神指点：
Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled.
2017-10-20 09:19:48.906 ERROR 13288 --- [ main] o.s.b.d.LoggingFailureAnalysisReporter :

APPLICATION FAILED TO START

Description:

Parameter 0 of constructor in org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration required a bean of type 'javax.sql.DataSource' that could not be found.
- Bean method 'dataSource' not loaded because @ConditionalOnProperty (spring.datasource.jndi-name) did not find property 'jndi-name'
- Bean method 'dataSource' not loaded because @ConditionalOnBean (types: org.springframework.boot.jta.XADataSourceWrapper; SearchStrategy: all) did not find any beans

Action:

Consider revisiting the conditions above or defining a bean of type 'javax.sql.DataSource' in your configuration.

都说了不采用 继承JpaRepository，网上全是继承 JpaRepository教程，这个我知道，有大神指教下吗？

题主你的sql写错了，，，我试了一下，，可以这样查，，

     @PersistenceContext
    private EntityManager entityManager;

    @Test
    public void finAllUserNum() {
        String hql = "select id,name,num,other_str from user_num";
        Query query = entityManager.createQuery(hql);
        List<UserNum> testEntities = query.getResultList();
    }

【注意】，，select 后面的字段要和Entity，的属性对应，，

有问题还可以追问。。我刚刚测了完美通过

已解决，是maven下载的jar有问题，可能网络不好，重新再springboot官网导入相同版本项目，发现好几个jar存在却报错，删除了重新maven update，另外实体类主键写错了，话你是不细心@Entity
@Table(name = "t_test")
