坑！
以下是報錯內容：
Error creating bean with name 'loginUsersService': Unsatisfied dependency expressed through field 'loginUsersRepository'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loginUsersRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Failed to create query for method public abstract com.swun.recommends.web.domain.LoginUsers com.swun.recommends.web.dao.LoginUsersRepository.saveLoginUser(com.swun.recommends.web.domain.Users)! No property saveLoginUser found for type LoginUsers!
只是因爲方法名：saveLoginUser 這麼寫不符合規範，改成 save 就通過了...
命名要規範
