Java 无法自动关联字段@Autowired批注

java spring hibernate jpa

Java 无法自动关联字段@Autowired批注,java,spring,hibernate,jpa,autowired,Java,Spring,Hibernate,Jpa,Autowired,我在JDK1.7中使用SpringVersion3和HibernateVersion4。我无法解决无法自动连接字段的错误 Login.java LoginAPIController.java LoginDaoImpl.java LoginServiceImpl applicationContext.xml 命名查询中存在错误 @NamedQuery( name = "validateUserQuery", query = "from Login l w

我在JDK1.7中使用SpringVersion3和HibernateVersion4。我无法解决无法自动连接字段的错误

LoginAPIController.java

LoginDaoImpl.java

LoginServiceImpl

applicationContext.xml

命名查询中存在错误

 @NamedQuery(  
        name = "validateUserQuery",  
        query = "from Login l where l.userName =:userName AND l.userPassword =:userPassword" 
        )

您指的是

l.userPassword

，但该字段称为

password

。将

l.userPassword

更改为

password

你能评论一下@Service（“loginService”）吗？也可以展示一下你的loginServiceinterface@georgesvan我注释掉了它，仍然出现问题。@georgesvan公共接口登录服务{public Login validateUser（字符串用户名，字符串用户密码）引发异常；}可能重复的
