Это старый пост, но он по-прежнему считается одним из лучших результатов для «входа в Spring Ajax», поэтому я решил поделиться своим решением. Он соответствует стандартам Spring Security и довольно прост в настройке. Уловка состоит в том, чтобы в вашей конфигурации безопасности было 2 <http> элемента, один для REST / Ajax и один для остальной части приложения (обычные страницы HTML). Порядок, в котором появляются <http>, важен, он должен перейти от более специфических к более общим URL, точно так же, как <url-intercept> элементы внутри <http>.
Шаг 1. Настройка двух отдельных <http>

<!-- http config for REST services (AJAX interface)
=================================================== -->
<http auto-config="true" use-expressions="true" pattern="/rest/**">
<!-- login configuration
login-processing-url="/rest/security/login-processing" front-end AJAX requests for authentication POST to this URL
login-page="/rest/security/login-page" means "authentication is required"
authentication-failure-url="/rest/security/authentication-failure" means "authentication failed, bad credentials or other security exception"
default-target-url="/rest/security/default-target" front-end AJAX requests are redirected here after success authentication
-->
<form-login
login-processing-url="/rest/security/login-processing"
login-page="/rest/security/login-page"
authentication-failure-url="/rest/security/authentication-failure"
default-target-url="/rest/security/default-target"

<logout logout-url="/rest/security/logout-url" />
<!-- REST services can be secured here, will respond with JSON instead of HTML -->
<intercept-url pattern="/rest/calendar/**" access="hasRole('ROLE_USER')" />
<!-- other REST intercept-urls go here -->
<!-- end it with a catch all -->
<intercept-url pattern="/rest/**" access="isAuthenticated()" />
<!-- reference to the shared request cache -->
<request-cache ref="requestCache"/>
</http>
<!-- http config for regular HTML pages
=================================================== -->
<http auto-config="true" use-expressions="true">
<form-login
login-processing-url="/security/j_spring_security_check"
login-page="/login"
authentication-failure-url="/login?login_error=t" />
<logout logout-url="/security/j_spring_security_logout" />
<intercept-url pattern="/calendar/**" access="hasRole('ROLE_USER')" />
<!-- other intercept-urls go here -->
<!-- in my app's case, the HTML config ends with permitting all users and requiring HTTPS
it is always a good idea to send sensitive information like passwords over HTTPS -->
<intercept-url pattern="/**" access="permitAll" requires-channel="https" />
<!-- reference to the shared request cache -->
<request-cache ref="requestCache"/>
</http>
<!-- authentication manager and other configuration go below -->
</beans:beans>
Шаг 2: Контроллер аутентификации REST
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import flexjson.JSONSerializer;
@Controller
@RequestMapping(value = "/rest/security")
public class RestAuthenticationController {
public HttpHeaders getJsonHeaders() {
HttpHeaders headers = new HttpHeaders();
headers.add("Content-Type", "application/json");
return headers;
}
@RequestMapping(value="/login-page", method = RequestMethod.GET)
public ResponseEntity<String> apiLoginPage() {
return new ResponseEntity<String>(getJsonHeaders(), HttpStatus.UNAUTHORIZED);
}
@RequestMapping(value="/authentication-failure", method = RequestMethod.GET)
public ResponseEntity<String> apiAuthenticationFailure() {
// return HttpStatus.OK to let your front-end know the request completed (no 401, it will cause you to go back to login again, loops, not good)
// include some message code to indicate unsuccessful login
return new ResponseEntity<String>("{\"success\" : false, \"message\" : \"authentication-failure\"}", getJsonHeaders(), HttpStatus.OK);
}
@RequestMapping(value="/default-target", method = RequestMethod.GET)
public ResponseEntity<String> apiDefaultTarget() {
Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
// exclude/include whatever fields you need
String userJson = new JSONSerializer().exclude("*.class", "*.password").serialize(authentication);
return new ResponseEntity<String>(userJson, getJsonHeaders(), HttpStatus.OK);
}
}
Шаг 3. Отправка формы AJAX и обработка ответа, необходимая библиотека jQuery ajaxForm
<form action="/rest/security/login-processing" method="POST">
...
</form>
$('form').ajaxForm({
success: function(response, statusText, xhr, $form) {
console.log(response);
if(response == null || response.username == null) {
alert("authentication failure");
} else {
// response is JSON version of the Spring's Authentication
alert("authentication success");
}
},
error: function(response, statusText, error, $form) {
if(response != null && response.message == "authentication-failure") {
alert("authentication failure");
}
}
});
