在My SpringBoot/JPA（Postgres）项目中，
我有一个项目表，定义为：

create table projects(
 project_id int primary key,
 name varchar(255),
 description text
);

字符串
在我的控制器中，我有一个获取项目列表的方法：

@GetMapping("/list")
@ResponseBody
public Page<Project> list(@AuthenticationPrincipal UserDetails currentUserDetails) {
    int page = 0;
    int size = 100;
    Sort sort = Sort.by("name").ascending();
    PageRequest p = PageRequest.of(page, size, sort);

    return projectService.list(p);
}

这一切都很好。当我将这段代码改为按project_id列排序时，问题出现了：

Sort sort = Sort.by("project_id").ascending();

现在，我得到了以下异常：
2024-01-01T14：34：04，424 ERROR [http-nio-8081-exec-6] o.a.j.l.DirectJDKLog：Servlet.service（）for servlet [dispatcherServlet] in context with path [] throughed exception [Request processing failed：org.springframework.data.mapping.PropertyReferenceException：No property 'project' found for type 'Project'] with root cause org.springframework.data.mapping.PropertyReferenceException：在org. springframework. data. mapping. PropertyPath中找不到类型“Project”的属性“project”。（PropertyPath.java：90）
我的Project实体类非常简单：

@Entity
@Table(name = "Projects")
public class Project {
@Id
@GeneratedValue(generator = "ProjectSeq")
@SequenceGenerator(name = "ProjectSeq", sequenceName = "PROJECTS_PROJECT_ID_SEQ", allocationSize = 1)
Integer project_id;
String name;

public Integer getProject_id() {
    return project_id;
}

public void setProject_id(Integer project_id) {
    this.project_id = project_id;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public String getDescription() {
    return description;
}

public void setDescription(String description) {
    this.description = description;
}

String description;
}

我是不是陷入了一个保留字的境地？
