java - 用户缺少权限或找不到对象

Question

所以我已经在 Google 和堆栈中进行了搜索，我发现了一堆有相同错误的人，但似乎没有一个解决方案可以解决我的问题。

我在用什么:

• Java 8
• JavaEE7
• TomEE 7.0 M3
• JPA 2.0
• ORM 1.0
• Postgres

我认为问题出在命名查询和 ManyToMany 关系上。

下面是代码

实体

用户.java

@Entity
@Table(name ="system_user")
public class User {
    @Id
    @Column
    private int id;
    @Column
    private String login;
    @Column
    private String password;

    @ManyToMany
    @JoinTable(
            name="user_role_relation",
            joinColumns=@JoinColumn(name="user_id", referencedColumnName="id"),
            inverseJoinColumns=@JoinColumn(name="role_id", referencedColumnName="id"))
    private List<SystemRole> rolesRelation;

    @Transient
    private List<Role> roles;

    public User(){}

    public List<Role> getRoles(){
        if(this.roles == null){
            List<Role> roles = new ArrayList<>(); 
            for(SystemRole relation : rolesRelation){
                roles.add(relation.getCode());
            }
            this.roles = roles;
        }
        return new ArrayList<>(this.roles);
    }

    public String getLogin(){
        return this.login;
    }

    public String getPassword(){
        return this.password;
    }
}

系统角色.java

@Entity
@Table(name="system_role")
public class SystemRole{
    @Id
    private int id;
    @Column
    private String name;

    @Column
    @Enumerated(EnumType.STRING)
    private Role code;

    @ManyToMany(mappedBy="rolesRelation")
    private List<User> users;

    public SystemRole(){}

    Role getCode(){
        return this.code;
    }

    public static  enum Role {
        MANAGER, EXECUTIVE, HRBP, ADMIN, USER;
    }
}

XML 配置

我用来返回用户的示例代码

资源

测试资源.java

@Path("/user-test")
@Produces("plain/text")
@RequestScoped
public class TestResource {

    @EJB(beanName="userdao")
    private UserRepository userRepository;

    @GET
    public void getTest(){
        userRepository.getByLogin("admin");
        System.out.println("teste");
    }

}

接口(interface)和DAO

用户库.java

@Local
public interface UserRepository {
    public User getByLogin(String login);
}

UserDAO.java

@Stateless(name="userdao")
public class UserDAO implements UserRepository{

    @PersistenceContext(unitName = "Pulse-PU")
    private EntityManager  entityManager;


    public User getByLogin(String login) {
        return entityManager.createNamedQuery("User.getByLogin", User.class)
                            .setParameter("login", login)
                            .getSingleResult();
    }

}

最后是异常(exception)

抱歉这篇文章太长了，但我想把所有重要的代码都放在一起。因此，如果遗漏任何信息，请告诉我。我真的不知道是什么问题，虽然问题是缺少公共(public) setter ，但据我所知 JPA 不需要使用 setter 。

Answer 1

所以，我已经解决了问题，这是一个配置问题。我注意到在 persistence.xml 中它指向 java:global/jdbc/postgresds 并且我在应用程序目录的 META-INF 中的 context.xml 中定义资源。资源的名称是jdbc/postgresds，所以我只是删除了jta-data-source 中的global 并且不得不在资源中添加JtaManaged="true"。

现在一切正常。
