Spring Social /connect 返回 HTTP 404

Question

当我尝试打开 /connect/linkedin 时，Spring 找不到 html 视图并且我得到 404。在对that post 的引用中，我仔细检查了 webapp 文件夹中的路径。这是我的 SpringSocialConfig

@Configuration
@EnableSocial
public class SocialConfig implements SocialConfigurer {

    @Inject
    private DataSource dataSource;

    @Override
    public void addConnectionFactories(ConnectionFactoryConfigurer connectionFactoryConfigurer, Environment environment) {
        connectionFactoryConfigurer.addConnectionFactory(new LinkedInConnectionFactory("xxxxxx", "xxxxxx"));
    }

    @Override
    public UserIdSource getUserIdSource() {
        return new UserIdSource() {
            @Override
            public String getUserId() {
                Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
                if (authentication == null) {
                    throw new IllegalStateException("Unable to get a ConnectionRepository: no user signed in");
                }
                return authentication.getName();
            }
        };
    }

    @Bean
    public ConnectController connectController(ConnectionFactoryLocator connectionFactoryLocator, ConnectionRepository connectionRepository) {
        return new ConnectController(connectionFactoryLocator, connectionRepository);
    }


    @Bean
    @Scope(value = "request", proxyMode = ScopedProxyMode.INTERFACES)
    public LinkedIn linkedin(ConnectionRepository repository) {
        Connection<LinkedIn> connection = repository.findPrimaryConnection(LinkedIn.class);
        return connection != null ? connection.getApi() : null;
    }

    @Override
    public UsersConnectionRepository getUsersConnectionRepository(ConnectionFactoryLocator connectionFactoryLocator) {
        return new JdbcUsersConnectionRepository(dataSource, connectionFactoryLocator, Encryptors.noOpText());
    }
}

我的 HomeController 带有 /linkedin 映射处理程序

@Inject
private ConnectionRepository connectionRepository;

@Inject
private LinkedIn linkedIn;

@Inject
public HomeController(LinkedIn linkedIn) {
    this.linkedIn = linkedIn;
}

@RequestMapping(value = "/linkedin", method = RequestMethod.GET)
public String home(Principal currentUser, Model model) {
    Connection<LinkedIn> connection = connectionRepository.findPrimaryConnection(LinkedIn.class);
    if (connection == null) {
        return "redirect:/connect/linkedin";
    }
    model.addAttribute("profile", connection.getApi().profileOperations().getUserProfileFull());
    return "linkedin/profile";
}

还有我的带有视图的 WEBAPP 文件夹

正如我在日志中看到的那样，发生了一些事情并且发现了 /connect/* 映射。

[local

我正在使用 Thymeleaf 3.0

@Bean
public ViewResolver viewResolver() {
    ThymeleafViewResolver resolver = new ThymeleafViewResolver();
    resolver.setTemplateEngine(templateEngine());
    resolver.setCharacterEncoding("UTF-8");
    resolver.setContentType("text/html; charset=UTF-8");
    return resolver;
}

@Bean
public TemplateEngine templateEngine() {
    SpringTemplateEngine engine = new SpringTemplateEngine();
    engine.setEnableSpringELCompiler(true);
    engine.setTemplateResolver(templateResolver());
    engine.addDialect(new SpringSecurityDialect());
    return engine;
}

 private ITemplateResolver templateResolver() {
        SpringResourceTemplateResolver resolver = new SpringResourceTemplateResolver();
        resolver.setApplicationContext(applicationContext);
        resolver.setPrefix("/views/");
        resolver.setSuffix(".html");
        resolver.setTemplateMode(TemplateMode.HTML);
        resolver.setCharacterEncoding("UTF-8");
        resolver.setCacheable(Boolean.parseBoolean(THYMELEAF_CACHE));
        return resolver;
    }

调度程序配置

public class WebAppInitializer implements WebApplicationInitializer {

    private final String APP_SERVLET_NAME = "x";
    private final String DISPLAY_NAME = "App";

    @Override
    public void onStartup(ServletContext container) {
        container.addListener(new ContextLoaderListener(getContext()));
        CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
        characterEncodingFilter.setEncoding("utf-8");
        characterEncodingFilter.setForceEncoding(true);

        container.addFilter("charEncodingFilter", characterEncodingFilter).addMappingForUrlPatterns(null, false, "/*");
        container.addFilter("securityFilter", new DelegatingFilterProxy("springSecurityFilterChain")).addMappingForUrlPatterns(null, false, "/*");
        container.addFilter("apiFilter", new DelegatingFilterProxy("apiExceptionHandler"));
        container.addFilter("hidden", new HiddenHttpMethodFilter());

        AnnotationConfigWebApplicationContext dispatcherServlet = new AnnotationConfigWebApplicationContext();
        dispatcherServlet.register(ServletConfig.class);

        ServletRegistration.Dynamic dispatcher = container.addServlet(APP_SERVLET_NAME, new DispatcherServlet(dispatcherServlet));
        dispatcher.setLoadOnStartup(1);
        dispatcher.addMapping("/");
    }

    private AnnotationConfigWebApplicationContext getContext() {
        AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
        rootContext.register(JPARepositoryConfig.class,
                ThymeleafConfig.class,
                WebSecurityConfig.class,
                SocialConfig.class,
                MailConfig.class,
                MongoRepositoryConfig.class,
                ServiceConfig.class,
                CacheConfig.class);

        rootContext.setDisplayName(DISPLAY_NAME);
        return rootContext;
    }

我在 Spring Social 的 Connection Controller 中设置了断点，并且调用了非映射方法。所以我认为应用配置很混乱。

编辑 我有错误的spring servlet配置。我将 spring 社交控制器注册为 root servlet。

Answer 1

我认为问题在于您的视图的位置。

您在src/main/webapp 下拥有它，而spring 正在src/main/resources 下搜索视图。

要么将所有 html 文件移动到 src/main/resources/views，要么更改配置以便 spring 在 src/main/webapp/views 下搜索。

检查此Example 配置与您的配置相似，但视图位于src/main/resources 文件夹下。

Answer 2

我猜你的 application.properties 文件中可能需要spring.social.auto-connection-views=true

Answer 3

我知道已经很久了，但我想我找到了解决这个问题的方法。

问题是，您的 spring 配置发现 'ConnectController' 作为 bean，但它没有映射为 Controller。另外，我检查了 ConnectController 类的来源。原来它是根据前缀和providerId构建视图名称的。

按照这个答案：https://stackoverflow.com/a/19699607/4544269

我继承了 ConnectController，并覆盖了“connectView”和“connectedView”，现在指向 WEB-INF 文件夹中的 Freemarkers 模板。

@Controller
public class CustomConnectController extends ConnectController{

    @Autowired
    public CustomConnectController(
            ConnectionFactoryLocator connectionFactoryLocator,
            ConnectionRepository connectionRepository) {
        super(connectionFactoryLocator, connectionRepository);
    }

    @Override
    protected String connectedView(String providerId){
        return "connect/facebookConnected";
    }

    @Override
    protected String connectView(String providerId) {
        return "connect/facebookConnect";
    }

   }
