ubuntu Sping Boot 循环引用已在application.properties中处理，但似乎被Java Sping Boot 可执行jar文件忽略

所以这个案例是我使用Java Sping Boot 创建的一个简单的登录员工管理系统（非常基本，所以它足以进行登录-注销和CRUD操作）。我还尝试使用Spring Security来保护身份验证。
这是我的Java Sping Boot 应用程序的规范：

  • Spring工具套件4.18.0.RELEASE
  • Spring安全6
  • 使用Java 17
  • 构建在Linux ubuntu 22.04之上
  • application.properties已经默认位于SBTLEmpManSys/src/main/resources中的资源文件夹中

我将附上我的java文件相关的错误，application.properties，和pom.xml后，但这是我已经处理。我已经把这个代码spring.main.allow-circular-references=true在我的application.properties来处理这个错误，它实际上工作

  1. The dependencies of some of the beans in the application context form a cycle:
  3. ┌─────┐
  4. |  securityConfiguration (field private org.springframework.security.config.annotation.web.builders.HttpSecurity org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration.httpSecurity)
  5. ↑     ↓
  6. |  org.springframework.security.config.annotation.web.configuration.HttpSecurityConfiguration.httpSecurity defined in class path resource [org/springframework/security/config/annotation/web/configuration/HttpSecurityConfiguration.class]
  7. └─────┘

当我在Spring Tool Suite IDE中运行它时，一切都运行得很好。
但是问题发生在我把我的Java Sping Boot 应用程序打包到可执行的jar文件中之后。文件application.properties似乎被忽略了。
循环引用似乎发生在EmpServiceImpl.java中这行代码周围：

  1. @Service
  2. public class EmpServiceImpl implements EmpService {
  4.     @Autowired
  5.     private EmployeeRepository empRepDAO;
  6.     
  7.     //public EmpServiceImpl(@Lazy EmployeeRepository empRepDAO) { //ANNOTATION '@Lazy' is ADDITION to AVOID CIRCULAR REFERENCE --> ANNOTATION NOT WORKING
  8.     public EmpServiceImpl(EmployeeRepository empRepDAO) {
  9.         super();
  10.         this.empRepDAO = empRepDAO;
  11.     }
  13. ...[AND_SO_ON]

我运行jar文件的方式是通过终端进入target目录，然后用java -jar SBTLEmpManSys-0.0.1-SNAPSHOT.jar运行它。这是我运行应用程序时得到的错误片段。

  1. Application run failed
  3. org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'empServiceImpl': Unsatisfied dependency expressed through field 'passwordEncoder': Error creating bean with name 'securityConfiguration': Unsatisfied dependency expressed through field 'httpSecurity': Error creating bean with name 'org.springframework.security.config.annotation.web.configuration.HttpSecurityConfiguration.httpSecurity' defined in class path resource [org/springframework/security/config/annotation/web/configuration/HttpSecurityConfiguration.class]: Failed to instantiate [org.springframework.security.config.annotation.web.builders.HttpSecurity]: Factory method 'httpSecurity' threw exception with message: Error creating bean with name 'passwordEncoder': Requested bean is currently in creation: Is there an unresolvable circular reference?

我想知道为什么错误消息说这个Requested bean is currently in creation: Is there an unresolvable circular reference?，因为它应该已经在application.properties中处理了。
有人能帮忙吗？任何帮助将非常感谢。谢谢各位;）
我的SecurityConfiguration.java

  1. package com.kastamer.sbtl.config;

  24.     @Bean
  25.     public BCryptPasswordEncoder passwordEncoder() {
  26.         // TODO Auto-generated method stub
  27.         return new BCryptPasswordEncoder();
  28.     }
  29.     
  30.     @Bean
  31.     public SecurityFilterChain configure(HttpSecurity http) throws Exception {
  32.         // TODO Auto-generated method stub
  33.         http.authorizeHttpRequests((requests) -> requests.requestMatchers(
  34.                 "/registrasi",

  36.                 "/css**",

  41.         
  42.         return http.build();
  43.     }
  44. }

  108.     @Override
  109.     public Page<Employee> findPaginated(int pageNo, int pageSize, String sortField, String sortAscOrDesc) {
  110.         // TODO Auto-generated method stub
  111.         Sort runut = sortAscOrDesc.equalsIgnoreCase(Sort.Direction.ASC.name()) ? Sort.by(sortField).ascending() : Sort.by(sortField).descending();
  112.         
  113.         Pageable pageable = PageRequest.of(pageNo - 1, pageSize, runut);
  114.         
  115.         return this.empRepDAO.findAll(pageable); //return null;
  116.     }
  117. }

这是我的application.properties：

  1. spring.datasource.url=jdbc:postgresql://localhost:5432/myDB
  2. spring.datasource.username=[POSTGRES_USERNAME]
  3. spring.datasource.password=[POSTGRES_PASSWORD]
  4. spring.datasource.driver-class-name=org.postgresql.Driver
  6. spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect
  8. spring.jpa.hibernate.ddl-auto=update
  10. logging.level.org.hibernate.sql=debug
  11. logging.level.org.hibernate.type=trace
  12. #spring.jpa.show-sql=true
  14. # Default user login and password for spring security web login page (if spring security is enabled)
  15. #spring.security.user.name=spring
  16. #spring.security.user.password=spring123 
  17. #spring.security.user.roles=USER
  19. spring.main.allow-bean-definition-overriding=true
  20. spring.main.allow-circular-references=true

明白了！我终于解决了循环引用后，消除extends WebSecurityConfiguration从我的代码在文件SecurityConfiguration.java
