目前我正在从事 Springboot 安全方面的工作,这对我来说是全新的。我关注了 youtube 视频教程 Video
当我使用以下代码片段时,我成功获得了 oauth2 access_token:-
@SpringBootApplication
public class MathifyApplication {
@Autowired
private PasswordEncoder passwordEncoder;
public static void main(String[] args) {
SpringApplication.run(MathifyApplication.class, args);
}
@Autowired
public void authenticationManager(AuthenticationManagerBuilder builder, UserRepository repository, UserService service) throws Exception {
//Setup a default user if db is empty
User students = new User("stu1", "user", "user", "abc@gmail.com", "1234567890", "12th", "dwarka sec-12",
0, 0 , "may/29/2017", "", Arrays.asList(new Role("USER"), new Role("ACTUATOR")));
if (repository.count()==0){
service.save(students);
}
builder.userDetailsService(userDetailsService(repository)).passwordEncoder(passwordEncoder);
}
private UserDetailsService userDetailsService(final UserRepository repository) {
return userName -> new CustomUserDetails(repository.findByUsername(userName));
}
}
Controller 类是:-
@RestController
public class LoginController {
@Autowired
private UserService userService;
@RequestMapping(value = "/mathify/getuser/{userId}", method = RequestMethod.GET)
public User getUser(@PathVariable String userId){
System.out.println("Userid "+userId);
return userService.getUser(userId);
}
@RequestMapping(method = RequestMethod.POST, value="/mathify/signup")
public User register(@RequestBody User user){
return userService.doSignup(user);
}
@GetMapping(value="/hi")
public String test(){
return "Oh ! I am fine without secuirity";
}
}
通过上面的代码片段我可以获得access_token(/oauth/token),我也可以毫无问题地调用其他 Controller 类私有(private)API。
但是上面的代码有问题。什么?在上面的代码片段中,用户是硬编码的,但是当我想在用户注册时获取 access_token 时,它给出了一个异常。

为了实现上述功能,我对应用程序和 Controller 做了一些更改
应用程序类为:-
@SpringBootApplication
public class MathifyApplication {
@Autowired
private PasswordEncoder passwordEncoder;
public static void main(String[] args) {
SpringApplication.run(MathifyApplication.class, args);
}
}
Controller 类如下:-
@RestController
public class LoginController {
@Autowired
private UserService userService;
@Autowired
AuthenticationManagerBuilder builder;
@Autowired
private PasswordEncoder passwordEncoder;
@Autowired
private UserRepository repository;
@RequestMapping(value = "/mathify/getuser/{userId}", method = RequestMethod.GET)
public User getUser(@PathVariable String userId){
System.out.println("Userid "+userId);
return userService.getUser(userId);
}
@RequestMapping(method = RequestMethod.POST, value="/user/signup")
public User register(@RequestBody User user) throws Exception {
User u = userService.doSignup(user);
builder.userDetailsService(userDetailsService(repository)).passwordEncoder(passwordEncoder);
return u;
}
private UserDetailsService userDetailsService(final UserRepository repository) {
return userName -> new CustomUserDetails(repository.findByUsername(userName));
}
@GetMapping(value="/hi")
public String test(){
return "Oh ! I am fine without secuirity";
}
}
任何帮助都将不胜感激。谢谢
最佳答案
您可以调用另一个 POST 请求来获取访问 token 。 我不确定这是最好的方法,但对我来说效果很好。
注册请求映射中的示例代码片段:
RestTemplate restTemplate = new RestTemplate();
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
headers.set("Authorization", auth_header);
/*auth_header should be Autorization header value that captured from signup request, which is generated by Basic Auth with clientID and secret, for example, "Basic bXktdHJ1c3RlZC1jbGllbnQ6c2VjcmV0" */
HttpEntity<String> entity = new HttpEntity<String>("",headers);
String authURL = "http://localhost:8080/oauth/token?grant_type=password&username=yourusername&password=yourpassword";
ResponseEntity<String> response = restTemplate.postForEntity(authURL, entity, String.class);
System.out.println(response.getBody());
