API Spring Boot自动重定向到登录页面

Question

我正在尝试将Spring Security性与spring boot restful API集成。我的项目代码如下：

web安全配置包括

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private BCryptPasswordEncoder bCryptPasswordEncoder;

    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http.csrf().ignoringAntMatchers("/API/**");
        http.authorizeRequests()
        .antMatchers("/API/user/**").permitAll()
        .and().exceptionHandling().accessDeniedPage("/access-denied");

    }
}

@RestController
@RequestMapping("/API/user")
public class UserRestApiController {

    @Autowired
    UserService userService;

    @RequestMapping(value="/all", method=RequestMethod.GET)
    public ResponseEntity<Collection<Users>> getAll(){
        return new ResponseEntity<Collection<Users>>(userService.getAlluser(), HttpStatus.OK);
    }

    @RequestMapping(value="/{id}", method=RequestMethod.GET)
    public ResponseEntity<Users> getUser(@PathVariable(value="id") int id){
        return new ResponseEntity<Users>(userService.getUser(id), HttpStatus.OK);
    }

    @RequestMapping(value="/delete/{id}", method=RequestMethod.PUT)
    public String deleteUser(@PathVariable(value="id")int id){
        userService.deleteUser(id);
        return "DELETED";
    }

    @RequestMapping(value="/create", method=RequestMethod.POST)
    public ResponseEntity<String> addUser(@Valid @RequestBody Users user){
        return new ResponseEntity<String>(userService.addUser(user), HttpStatus.OK);
    }

    @RequestMapping(value="/update", method=RequestMethod.PUT)
    public ResponseEntity<Object> updateUser(@Valid @RequestBody Users user){
        return new ResponseEntity<Object>(userService.updateUser(user), HttpStatus.OK);
    }
}

public class UserService {

    @Autowired
    private UserRepository userRepository;

    @Autowired
    private PasswordEncoder passwordEncoder;

    public Collection<Users> getAlluser() {
        return userRepository.findAll();
    }

    public Users getUser(int id) {
        return userRepository.getOne(id);
    }

    public void deleteUser(int id) {
        userRepository.deleteById(id);
    }

    public Users updateUser(Users user) {
        //Users u = userRepository.getOne(user.getId());
        Users userUpdate = null;
        if(userRepository.findById(user.getId()) != null) {
             userUpdate = userRepository.save(user);
        }
        return userUpdate;
    }

    public String addUser(Users user) {
        Users tmpUser = userRepository.findByUsername(user.getUsername());
        if(tmpUser == null) {
            userRepository.save(user);
            return "CREATED";
        } else {
            return "EXISTED";
        }
    }
}

你能帮我清理这个案子吗？

与Spring MVC不同，REST服务不应该将用户重定向到登录页面，因为它是一种资源，而不是视图解析器。相反，调用方（例如web浏览器）在收到HTTP代码401时将用户重定向到登录页面。
