Spring Boot - Spring安全依賴的問題：UserDetailsS​​ervice.class無法打開，因爲它不存在

Question

直到今天我的應用程序運行良好，但突然間我得到了這個異常，我不知道該如何修復它。

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to parse configuration class [com.company.app.Application]; nested exception is java.io.FileNotFoundException: class path resource [org/springframework/security/core/userdetails/UserDetailsService.class] cannot be opened because it does not exist 
at org.springframework.context.annotation.ConfigurationClassParser.parse(ConfigurationClassParser.java:180) ~[spring-context-5.0.0.RC3.jar:5.0.0.RC3]

我評論貫徹UserDetailsService類，但現在我有這樣的例外：

Caused by: java.lang.ClassNotFoundException: org.springframework.security.core.GrantedAuthority 
at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1269) ~[catalina.jar:9.0.0.M22] 
at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1104) ~[catalina.jar:9.0.0.M22] 
... 80 common frames omitted 

好像Spring Security的依賴會帶來一些麻煩。

我的pom.xml（摘要）：

     <artifactId>spring-boot-starter-test</artifactId> 
     <scope>test</scope> 
    </dependency> 

</dependencies> 

我實現（即使這不是問題）：

@Service 
public class CustomUserDetailsService implements UserDetailsService { 

    @Autowired 
    private SecurityService securityService; 

    @Override 
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException { 
    return new CustomUserDetails(securityService.findUserCredentialsByUsername(username)); 
    } 
} 

編輯

這似乎有些奇怪，因爲我可以運行我的測試，並且所有這些測試都會加載主類Application的上下文。測試不會失敗，但是當我在Tomcat中運行應用程序時，它會失敗！

有什麼想法？由於

Answer 1

好像你的類路徑是過時的，因爲UserService.class和GrantedAuthority.class文件不被發現。你可以通過更新你的Maven依賴關係來解決這個問題，並確保依賴關係在類路徑中。

Answer 2

也許你在本地的maven倉庫中有一個損壞的jar文件。這可能會導致錯誤，因爲maven無法訪問這些jar文件中的類文件。
