我启动了 spring mvc 项目并尝试在那里使用 JPA。我有类 User 和 BasePersistable 以及由@RooJavaBean 生成的访问器。

import javax.persistence.GeneratedValue;
import javax.persistence.MappedSuperclass;
import javax.persistence.Version;

import org.springframework.data.annotation.Id;
import org.springframework.data.domain.Persistable;
import org.springframework.roo.addon.javabean.RooJavaBean;

@RooJavaBean
@MappedSuperclass
public abstract class BasePersistable implements Persistable<Long> {

    private static final long serialVersionUID = -3281161320810540373L;

    @Id
    @GeneratedValue
    private Long id;

    @Version
    private Integer version;

    @Override
    public boolean isNew() {
        return getId() == null;
    }

}

和

@Entity
@RooJavaBean
public class User extends BasePersistable {

    private static final long serialVersionUID = -1999311284585286126L;

    private String username;
    private String passwrd;
    private String firstname;
    private String lastname;
    private String email;

    @Temporal(TemporalType.TIMESTAMP)
    private Calendar signupDate;

    private Sex sex;
    private String comment;

}

Roo 肯定会生成 getter 和 setter。我可以在代码中访问 getId() 方法:

User user = new User();
user.getId();

但是我得到了这个错误:

看来我觉得AspectJ有些问题。谁能帮忙？

UPD

这里是 BasePersistable_Roo_JavaBean.aj

// WARNING: DO NOT EDIT THIS FILE. THIS FILE IS MANAGED BY SPRING ROO.
// You may push code into the target .java compilation unit if you wish to edit any member(s).

package com.test.mvc1.domain;

import com.test.mvc1.domain.BasePersistable;

privileged aspect BasePersistable_Roo_JavaBean {

    public Long BasePersistable.getId() {
        return this.id;
    }

    public void BasePersistable.setId(Long id) {
        this.id = id;
    }

    public Integer BasePersistable.getVersion() {
        return this.version;
    }

    public void BasePersistable.setVersion(Integer version) {
        this.version = version;
    }

}

顺便说一下，如果将 stub 方法 getId() 添加到 User 类:

public Long getId() {
        return 1L; 
}

UPD 2我什至无法想象这个项目出了什么问题。我在 pom 文件中添加了新的依赖项，但 maven 没有下载它。这是我的 pom:
