将我的项目升级到 Spring Boot 后2.6.0，我在启动过程中遇到以下异常：
org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'webSecurityConfig': Requested bean is currently in creation: Is there an unresolvable circular reference?

但是，我的配置似乎符合 Spring 文档（HttpSecurity setup、AuthenticationManagerBuilder setup和PasswordEncoder setup）：
@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void …我有以下 Spring Data JPA 存储库：
public interface FooRepository extends PagingAndSortingRepository<Foo, Long> {}
迁移到 Spring Boot 3 后，我开始收到大多数标准存储库方法的错误消息（例如fooRepository.findById(id)，，，）fooRepository.save(foo)fooRepository.findAll()
我在Spring Boot 3.0迁移指南中找不到与此相关的任何内容
我的项目中有以下控制器端点：
@GetMapping(value = "/{id}")
public FooDto findOne(@PathVariable Long id) {
Foo model = fooService.findById(id)
.orElseThrow(() -> new ResponseStatusException(HttpStatus.NOT_FOUND));
return toDto(model);
}
当我的应用程序找不到Foo具有提供的 id 的响应时，它检索到以下响应：
{
"timestamp": "2023-01-06T08:43:12.161+00:00",
"status": 404,
"error": "Not Found",
"path": "/foo/99"
}
但是，升级到 Boot 3 后，响应正文更改为：
{
"type": "about:blank",
"title": "Not Found",
"status": 404,
"instance": "/foo/99"
}
我在《Spring Boot 3.0 迁移指南》和《升级到 Spring Framework 6.x 》中都找不到任何相关信息。
我有一个配置了 Spring Boot 和 Spring Data JPA 的项目。
我的项目包含以下data.sql初始化脚本（我刚刚开始开发我的应用程序，这就是我使用嵌入式 H2 数据库的原因）：
INSERT INTO Project(id, name) VALUES (1, 'Project 1');
我正在定义以下实体：
@Entity
public class Project {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String name;
protected Project() {
}
public Project(String name) {
this.name = name;
}
// ...
}
我没有任何其他配置/设置。

我在日志中看到此警告消息，但不清楚原因或解决方案：
