jpa依赖hibernate的,项目缺少hibernate的相关依赖
引入hibernate-jpa-2.1-api依赖
pom文件dependencies标签中添加

org.hibernate.javax.persistence
hibernate-jpa-2.1-api
1.0.0.Final

再clean一下项目

SpringBoot+JPA死锁问题

有一个查询语句 select * from 表1 WHERE name = #{request.name} <![CDATA[ AND age >= #{minAge} AND age <= #{maxAge} ]]> <![CDATA[ AND weight >= #{minWeight} AND latitude <= #{maxWeight} ]]> 这样一个查询语句,如何转换成使用SpringBoot+jpa+Hibernate方式的查询呢?
springboot JPA的DAO报错NullPointerException
初次尝试搭建一个springboot框架,目前进行到JPA操作数据库这一步,但是继承了JpaRepository的UserDAO接口总是报空指针错误。 这是UserDAO: ``` @Repository public interface UserDAO extends JpaRepository<User,Long> { } ``` 这是测试类: ``` @Service public class Tes { @Autowired public UserDAO user; public void t() { User u = new User(); u.setAccount("ff"); u.setName("asufhua"); u.setPassword("123456"); u.setQx(1); user.save(u); } } ``` 这是Controller,在跳转首页之前,会调用Tes类往数据库里插一条记录: ``` @Controller public class HelloController { @RequestMapping("/") public String index() { new Tes().t(); return "index"; } } ``` 现在我每次进入首页,就会提示user.save处的空指针错误,好像这个DAO没有注入成功一样。 到现在折腾一下午了,我只能初步认定**这个DAO没有注入成功**,所以会NULL。 之前我找到的一个解决办法:把DAO和测试类放在同一个目录下就可以成功,可为什么分开放就不行? 我现在的目录结构是启动类在顶层,然后下面有dao/domain/web/service等多个子包。像这样分开放,会提示“expected at least 1 bean which qualifies as autowire candidate.” 于是我尝试在启动类加上路径扫描@MapperScan("xx.xx.dao"),就不报找不到bean的错,可以运行起来。 但是跑起来后,涉及到dao的操作又会报空指针错误。 我感觉spring怎么这么乱呢?启动类为什么不会扫描下面的子包?为什么注入后又是NULL? 哪位大侠帮帮我?
