我正在使用Spring Boot开发一个Web应用程序。我已经使用了Spring Boot安全性。
如果我使用spring boot默认登录页面,则身份验证会按预期工作
但是它不适用于自定义登录页面。
如果在websecurity.java中配置http端点时使用自定义登录页面,我将重定向到登录页面
在下面共享示例代码和我的诊断。
@EnableGlobalMethodSecurity(prePostEnabled = true)
@EnableWebSecurity
@EnableJpaRepositories(basePackageClasses = UserRepository.class)
@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private CustomUserDetailsService userDetailsService;
@Override
public void configure(HttpSecurity http) throws Exception {
http.csrf().disable();
http.authorizeRequests().antMatchers("/resources/**").permitAll()
.anyRequest().authenticated()
.and().formLogin().loginPage("/loginPage")
.permitAll();
}
@Override
public void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService)
.passwordEncoder(getPasswordEncoder());
}
private PasswordEncoder getPasswordEncoder() {
return new PasswordEncoder() {
@Override
public String encode(CharSequence charSequence) {
return charSequence.toString();
}
@Override
public boolean matches(CharSequence charSequence, String s) {
return true;
}
};
}
}
控制器:
@Controller
@EnableAutoConfiguration
@ComponentScan("com.shopping.service")
public class ShoppingController {
@Autowired
private ShoppingService service;
@RequestMapping("/")
public String index() {
return "";
}
@RequestMapping("/loginPage")
public String welcome(Map<String, Object> model) {
return "login";
}
@RequestMapping(value = "/register")
public String register(Model model) {
model.addAttribute("user", new User());
return "register";
}
@RequestMapping(value = "/submitRegistration", method = RequestMethod.POST)
public String submitRegistration(@ModelAttribute User user) {
User saved = service.save(user);
System.out.println(saved);
return "login";
}
@RequestMapping("/home")
public String home() {
return "home";
}
}
login.html:
<form th:action="@{/loginPage}" method="post" th:object="${object}">
<div class="form-group">
<label for="username">Email address:</label>
<input type="email" name="username" class="form-control" id="username">
</div>
<div class="form-group">
<label for="password">Password:</label>
<input type="password" name="password" class="form-control" id="password">
</div>
<div class="checkbox">
<label><input type="checkbox"> Remember me</label>
</div>
<button type="submit" class="btn btn-primary">Submit</button>
<a href="/register" class="btn btn-default">Register</a>
</form>
UserDetailsService,用于使用Crud Repo从数据库进行用户身份验证
public class CustomUserDetailsService implements UserDetailsService {
@Autowired
private UserRepository userRepo;
@Override
public UserDetails loadUserByUsername(String userName) throws UsernameNotFoundException {
Optional<User> optionalUser = userRepo.findByEmail(userName);
optionalUser.orElseThrow(() -> new UsernameNotFoundException("User Name not found"));
UserDetailsImpl userDetails = optionalUser.map(user -> new UserDetailsImpl(user)).get();
return userDetails;
}
}
public class UserDetailsImpl extends User implements UserDetails {
@Override
public Collection<? extends GrantedAuthority> getAuthorities() {
return null;
}
public UserDetailsImpl(User user) {
this.setEmail(user.getEmail());
this.setAge(user.getAge());
this.setName(user.getName());
this.setId(user.getId());
this.setPassword(user.getPassword());
}
@Override
public String getPassword() {
return super.getPassword();
}
@Override
public String getUsername() {
return super.getEmail();
}
@Override
public boolean isAccountNonExpired() {
return true;
}
@Override
public boolean isAccountNonLocked() {
return true;
}
@Override
public boolean isCredentialsNonExpired() {
return true;
}
@Override
public boolean isEnabled() {
return true;
}
}
答案 0 :(得分:1)
您需要指定用户名的ID /名称和密码参数。
默认值为username
和password
,但是您使用email
和password
。
您可以在安全配置中更改默认设置:
//...
and().formLogin()
.loginPage("/loginPage")
.usernameParameter("email").passwordParameter("password")
//...
请注意,您只需要更改与默认设置不同的一种,我只想显示两种方法。

第二个错误是表单操作,它必须是loginPage("/loginPage")
方法指定的错误,因此在这种情况下:th:action="@{/loginPage}"
另外,密码标签的for属性错误(在这种情况下,必须为password
)。
我对此进行了测试,现在对我有用。

Spring安全性无法像您想象的那样起作用。它会拦截表单的操作URL,并将您重定向到您尝试登录之前访问的页面。如果要更改此页面,可以使用successForwardUrl()
在您的示例中:
//...
and().formLogin()
.loginPage("/loginPage")
.successForwardUrl("/home")
//...
