大佬教程收集整理的这篇文章主要介绍了java – Spring中的UnsatisfiedDependencyException：构造函数的非法参数：参数类型不匹配，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

我正在尝试在Departmentservice中注入DepartmentDAO.这是在我添加@transactional注释后出现的.所以这是我的Departmentservice：

@service
@transactional
public class Departmentservice extends AbstractCRUDservicesuper();
        this.departmentDAO = null;
    }

    @Inject
    public Departmentservice(DepartmentDAO departmentDAO) {
        super();
        this.departmentDAO = departmentDAO;
    }

    @Override   
    public Long create(DepartmentDTO dDTO) {        
        Department department = new Department();
        department.setDepName(dDTO.getDepName());
        return departmentDAO.create(department);
    }
...............read,update,delete,findAll methods...........................
}

这是我的部门DAO：

@Repository
@transactional(propagation = Propagation.MANDATORY)
public class DepartmentDAO extends AbstractCRUDDao

这是一个applicationContext.xml：
