Question

有一个注册用户的课程 `@服务公共类UserServiceImpl实现UserService {

@Autowired
UserDAO userDAO;

@Autowired
private RoleDAO roleDAO;

@Autowired
private ShaPasswordEncoder shaPasswordEncoder;

@Override
public void save(User user) {

    user.setPassword(shaPasswordEncoder.encodePassword(user.getPassword(),"mySalt"));
    System.out.println(user.getPassword());
    Set<Role> roles = new HashSet<>();
    roles.add(roleDAO.getOne(1L));
    user.setRoles(roles);
    userDAO.save(user);

}

@Override
public User findByUsername(String username) {
    return userDAO.findByUsername(username);
}

如你所见，我用盐在沙中编码在这里我试图编码

@Bean
public ShaPasswordEncoder getShaPasswordEncoder(){

    return new ShaPasswordEncoder();
}
@Autowired
public void registerGlobalAuthentication(AuthenticationManagerBuilder auth) throws Exception {
    auth
            .userDetailsService(userDetailsService)
            .passwordEncoder(getShaPasswordEncoder());
}

所以我可以在哪里指定一个盐来解码密码

Answer 1

您无法解码哈希密码。哈希函数是单向函数。因此，无法指定要解码的盐。

如何使用AuthenticationManagerBuilder
