春天方面不起作用，intellij

Question

我有一个有效的项目，然后突然停了下来。春天没有注入

@Configuration
@Order(2)
public static class RegularSecurityConfigurerAdapter extends WebSecurityConfigurerAdapter {

    @Inject
    private Environment env;

    @Inject
    private AjaxAuthenticationSuccessHandler ajaxAuthenticationSuccessHandler;
        //Could not autowire. No bean of name 'ajaxAuth..' type found
...

AjaxAuthenticationSuccessHandler类看起来像这样

@Component
public class AjaxAuthenticationSuccessHandler extends SimpleUrlAuthenticationSuccessHandler {

    @Autowired
    private UserRepository userRepository;
...

我发现facet已配置，但main方法和@ComponentScan文件的行是红色的。

这与我的问题有关吗？怎么告诉Spring ajaxAuth..班？即使我切换到以前工作的分支，也会发生这种情况。

以下是Application.java：

@ComponentScan
@EnableAutoConfiguration(exclude = {MetricFilterAutoConfiguration.class, MetricRepositoryAutoConfiguration.class})
public class Application {

    private static final Logger log = LoggerFactory.getLogger(Application.class);

    @Inject
    private Environment env;

    @PostConstruct
    public void initApplication() {
        if (env.getActiveProfiles().length == 0) {
            log.warn("No Spring profile configured, running with default configuration");
        } else {
            log.info("Running with Spring profile(s) : {}", Arrays.toString(env.getActiveProfiles()));
        }
    }

    /**
     * Main method, used to run the application.
     */
    public static void main(String[] args) throws UnknownHostException, NoSuchAlgorithmException {
        if (Cipher.getMaxAllowedKeyLength("AES") <= 128) {
            log.error("You need Java Cryptography Extension (JCE) to run the system");
            return;
        }

        TimeZone.setDefault(TimeZone.getTimeZone("UTC"));
        System.setProperty("user.timezone", "UTC");
        SpringApplication app = new SpringApplication(Application.class);
        app.setShowBanner(false);

        SimpleCommandLinePropertySource source = new SimpleCommandLinePropertySource(args);

        // Check if the selected profile has been set as argument.
        // if not the development profile will be added
        addDefaultProfile(app, source);
        addLiquibaseScanPackages();
        Environment env = app.run(args).getEnvironment();
//      System.setProperty("javax.net.ssl.trustStore", env.getProperty("server.ssl.key-store"));
//      System.setProperty("javax.net.ssl.trustStorePassword", env.getProperty("server.ssl.key-store-password"));

        String httpPort = env.getProperty("httpPort");
        String httpsPort = env.getProperty("server.port");

        String div = "----------------------------------------------------------";
        String local = "\tLocal: \t\thttps://127.0.0.1:" + httpsPort;
        String external = "\tExternal: \thttps://" + InetAddress.getLocalHost().getHostAddress() + ":" + httpsPort;

        if (httpPort != null) {
            div += "-----------------------------";
            local += " & http://127.0.0.1:" + httpPort;
            external += " & http://" + InetAddress.getLocalHost().getHostAddress() + ":" + httpPort;
        }

        log.info("Access URLs:\n" + div + "\n" + local + "\n" + external + "\n" + div);
    }

    /**
     * Set a default profile if it has not been set
     */
    private static void addDefaultProfile(SpringApplication app, SimpleCommandLinePropertySource source) {
        if (!source.containsProperty("spring.profiles.active")) {
            app.setAdditionalProfiles(Constants.SPRING_PROFILE_DEVELOPMENT);
        }
    }

    /**
     * Set the liquibases.scan.packages to avoid an exception from ServiceLocator.
     */
    private static void addLiquibaseScanPackages() {
        System.setProperty("liquibase.scan.packages", Joiner.on(",").join(
            "liquibase.change", "liquibase.database", "liquibase.parser",
            "liquibase.precondition", "liquibase.datatype",
            "liquibase.serializer", "liquibase.sqlgenerator", "liquibase.executor",
            "liquibase.snapshot", "liquibase.logging", "liquibase.diff",
            "liquibase.structure", "liquibase.structurecompare", "liquibase.lockservice",
            "liquibase.ext", "liquibase.changelog"));
    }

}

Answer 1

我在JHipster生成的Spring Boot应用程序类中遇到了同样的问题，直到我在类中添加了@Configuration注释：

@Configuration
@ComponentScan
@EnableAutoConfiguration(exclude = {MetricFilterAutoConfiguration.class, 
MetricRepositoryAutoConfiguration.class})
public class Application {
    /* ... */
}

这三个注释可以替换为单个@SpringBootApplication注释：

@SpringBootApplication(exclude = {MetricFilterAutoConfiguration.class, 
MetricRepositoryAutoConfiguration.class})
public class Application {
    /* ... */
}

两者似乎都适用于IDEA 2017.1。

Answer 2

似乎解决主要课程Application.java时出现问题。只需尝试删除并重新添加Spring facet（您还需要另外重新创建手动上下文）。
