如何将用户对象放入 UsernamePasswordAuthenticationToken(AuthenticationProvider)？

Question

当我尝试将当前用户对象放入由我的 CustomAuthenticationProvider 返回的 UsernamePasswordAuthenticationToken 时，我遇到了一些问题。 所以一开始我需要展示我的spring-security.xml，它看起来像这样：

    <http auto-config="true" use-expressions="true">
    <intercept-url pattern="/sign/in" access="isAnonymous()" /> 
    <intercept-url pattern="/sign/up" access="isAnonymous()" /> 
    <intercept-url pattern="/secret/page" access="isAuthenticated()" />
    <intercept-url pattern="/sign/out" access="isAuthenticated()" />
    <intercept-url pattern="/user/myinfo" access="isAuthenticated()" />

    <form-login
        login-page="/sign/in"
        default-target-url="/secret/page"
        authentication-failure-url="/sign/in?failed=1"
        password-parameter="password"
        username-parameter="email"
    />
    <csrf disabled="true"/>
    <logout
        logout-url="/sign/out"
    />

    </http>
    <authentication-manager erase-credentials="false">
    <authentication-provider ref="customAuth">
    </authentication-provider>
    </authentication-manager>

    <beans:bean id="customAuth" class="milkiv.easyword.controller.sign.CustomAuthenticationProvider"/>

我在页面 /sign/in 中输入我的电子邮件和密码进行登录。因此，使用 AuthenticationProvider 的下一个代码，我总是被重定向到我定义为 login-page="/sign/in 的页面“（不是失败网址，我已经检查过了）。顺便说一句，如果把 User 对象而不是 Username 放在它工作正常。所以我的AuthenticationProvider的代码是下一个：

@Service(value = "customAuth")
public class CustomAuthenticationProvider implements AuthenticationProvider {

    @Autowired
    public Storages storage;

    @Override
    @Transactional
    public Authentication authenticate(Authentication authentication) throws AuthenticationException {
    String login = authentication.getName();
    String password = authentication.getCredentials().toString();
    User user = storage.uSM.findByEmailAndPassword(login, password);
    if (user == null) {
        return null;
    } else {
        // if to pur here login insted of user it works fine
        return new UsernamePasswordAuthenticationToken(user, password);
    }
    }

    @Override
    public boolean supports(Class<?> authentication) {
    return authentication.equals(UsernamePasswordAuthenticationToken.class);
    }

}

有趣的是，在我的测试中，看起来：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:resources/spring-context.xml", "classpath:resources/spring-security.xml"})
@WebAppConfiguration
public class InTest {

    MockMvc mockMvc;

    Storages storages;

    @Autowired
    private Filter springSecurityFilterChain;

    private final String nickname = "LoremIpsum";
    private final String email = "lorem@ipsum.com";
    private final String password = "loreamipsumpassword";

    @Autowired
    WebApplicationContext wac; // cached

    @Before
    public void doBeforeTests() {
    mockMvc = MockMvcBuilders
        .webAppContextSetup(wac)
        .addFilters(springSecurityFilterChain)
        .build();
    ApplicationContext context = new ClassPathXmlApplicationContext("resources/spring-context.xml", "resources/spring-security.xml");
    storages = context.getBean(Storages.class);
    }

    @Test
    public void testSignIn() throws Exception {
    mockMvc.perform(
        formLogin()
            .user("email", email)
            .password(password)
    )
        .andExpect(redirectedUrl("/secret/page"));

} }

.andExpectFunction(redirectedUrl("/secret/page")) 说我已被重定向到 default-target-url="/secret/page"，所以看起来之后出现了问题。 正如我所读到的 AuthenticationProvider 以某种方式与 AuthenticatioManager 一起工作，也许问题出在此处？ 有人可以向我解释我的错误，或者帮助弄清楚发生了什么，或者提供一些帮助我理解的链接，或者其他的东西。我将不胜感激。 提前谢谢大家。

添加 用户模型：

public class User {
    private int userId;

    @NotBlank (message = "Email field can not be empty or missed")
    @Size(min = 5, max = 128, message = "Email field must have from 5 to 128 symbols")
    @Email(message = "Email field must have email format.")
    private String email;

    @NotBlank (message = "Password field can not be empty or missed")
    @Size (min = 5, max = 32, message = "Password field must have from 5 to 32 symbols")
    private String password;

    @NotBlank (message = "Confirm password field can not be empty or missed")
    @Size (min = 5, max = 32, message = "Confirm password field must have from 5 to 32 symbols")
    private String confirmPassword;

    @NotBlank (message = "Nickname field can not be empty or missed")
    @Size (min = 3, max = 32, message = "Nickname field must have from 3 to 32 symbols")
    private String nickname; 


    private Date registrationDate;

    private Set studyLanguages;

    public User(){
    }

    public int getUserId() {
    return userId;
    }

    public void setUserId(int userId) {
    this.userId = userId;
    }

    public String getEmail() {
    return email;
    }

    public void setEmail(String email) {
    this.email = email;
    }

    public String getPassword() {
    return password;
    }

    public void setPassword(String password) {
    this.password = password;
    }

    public String getNickname() {
    return nickname;
    }

    public void setNickname(String nickname) {
    this.nickname = nickname;
    }

    public Date getRegistrationDate() {
    return registrationDate;
    }

    public void setRegistrationDate(Date registration_date) {
    this.registrationDate = registration_date;
    }

    public Set getStudyLanguages() {
    return studyLanguages;
    }

    public void setStudyLanguages(Set studyLanguages) {
    this.studyLanguages = studyLanguages;
    }


    public String getConfirmPassword() {
    return confirmPassword;
    }

    public void setConfirmPassword(String confirmPassword) {
    this.confirmPassword = confirmPassword;
    }
}

我认为问题在于您以错误的方式使用 UsernamePasswordAuthenticationToken(user, password)。这里方法UsernamePasswordAuthenticationToken 等待两个参数：主体（通常是字符串用户名）和密码。

通过从Authentification object 获取它们，您做得很好，但用户对象不被视为主体，登录是。

    @Service(value = "customAuth")
public class CustomAuthenticationProvider implements AuthenticationProvider {

    @Autowired
    public Storages storage;

    @Override
    @Transactional
    public Authentication authenticate(Authentication authentication) throws AuthenticationException {
    String login = authentication.getName();
    String password = authentication.getCredentials().toString();
    User user = storage.uSM.findByEmailAndPassword(login, password);
    if (user == null) {
        return null;
    } else {
        // Here use the user object to only check if the user exists in the database if not null use his login ( principal ) and password
        return new UsernamePasswordAuthenticationToken(login, password);
    }
    }

    @Override
    public boolean supports(Class<?> authentication) {
    return authentication.equals(UsernamePasswordAuthenticationToken.class);
    }
}

这是一个link，这次您可以对您的用户对象执行相同的操作。您将使用UserDetails 和UserDetails
