2、1 昨天讲列表缓存，为了让列表更新，我们需要在增、删、改方法之前加@CacheEvict(value="list",allEntries = true)

15 @Service
16 public class StudentService implements IStudentService{
17     @Resource private StudentRepository studentRepository;
18
19     @Override
20     @Cacheable(value="list")
21     public List<Student> list() {
22         // TODO Auto-generated method stub
23         return studentRepository.findAll();
24     }
25
26     @Override
27     @CacheEvict(value="list",allEntries = true)
28     public void save(Student student) {
29         // TODO Auto-generated method stub
30         student.setPwd(MD5Util.md5(student.getPwd()));
31         studentRepository.save(student);
32     }
33
34     @Override
35     public Student login(Student student) {
36         // TODO Auto-generated method stub
37         return studentRepository.findBySnameAndPwd(student.getSname(),student.getPwd());
38     }
39
40     @Override
41     public Student findBySname(String sname) {
42         // TODO Auto-generated method stub
43         return studentRepository.findBySname(sname);
44     }
45
46     @Override
47     public Student findBySid(String  sid) {
48         // TODO Auto-generated method stub
49         return studentRepository.findBySid(sid);
50     }
