@Autowired()  //按类型来注解
@Qualifier("studentsDAO")//按名称来注解  这个注解一定的加上@Autowired
private StudentsDAO studentsDAO;

//@Resource(name = "student")//java标准的注解
private Students student;//

public boolean saveStudents(Students student)
{
if (studentsDAO.saveStudents(student))
{
System.out.println(student);
System.out.println(student.getAge());
return true;
