Injection of autowired dependencies failed

error：org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mainController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.euphe.repository.UserRepository com.euphe.controller.MainController.userRepository; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userRepository': Invocation of init method failed; nested exception is java.lang.IllegalStateException: Using named parameters for method public abstract void com.euphe.repository.UserRepository.updateUser(java.lang.String,java.lang.String,java.lang.String,java.lang.String,java.lang.Integer) but parameter 'qPassword' not found in annotated query ' update UserEntity us set us.nickname = :qNickname, us.firstName=:qFirstName, us.lastName =:qLastName, us.password =: qPassword where us.id =:qId'!

 

问题：这个函数没办法识别qPassword

解决：原函数是这样的：

@Query(" update UserEntity us set us.nickname = :qNickname, us.firstName=:qFirstName, " +
        "us.lastName =:qLastName, us.password =: qPassword where us.id =:qId")

看出问题来了吗？qPassword和别的的不同就是和：之间多了一个空格，所以没有被识别出来，自然不能Autowired了

 

修改之后：

@Query(" update UserEntity us set us.nickname = :qNickname, us.firstName=:qFirstName, " +
        "us.lastName =:qLastName, us.password =:qPassword where us.id =:qId")
