Question

我遵循Hibernate错误：＆＃34;无法确定类型：java.util.List，在表：user，对于列：[org.hibernate.mapping.Column（authorities）]＆＃34;

什么可能导致问题？

此外，是否可以在没有模型角色的情况下使用它，并设置return getAuthority role＆＃34; USER＆＃34;默认情况下？

用户模型：

@Entity
@Table(name = "user")
public class User implements UserDetails {

    private int id;
    private String username;
    private String password;
    private List<Role> roles;


    @Id
    @GeneratedValue
    @Column(name = "id")
    public int getId() {
        return id;
    }

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

    @Basic
    @Column(name = "username")
    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    @Basic
    @Column(name = "password")
    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }


    @Override
    public String getUsername() {
        return this.username;
    }

    @Override
    public boolean isAccountNonExpired() {
        return true;
    }

    @Override
    public boolean isAccountNonLocked() {
        return true;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }

    @Override
    public boolean isEnabled() {
        return true;
    }


    @Override
    public List<Role> getAuthorities() {
        return this.roles;
    }


    @OneToMany(mappedBy = "user")
    public List<Role> getRoles() {
        return this.roles;
    }

    public void setRoles(List<Role> roles) {
        this.roles = roles;
    }
}

角色模型：

@Entity
@Table(name = "role")
public class Role implements GrantedAuthority {

    private int id;
    private User user;
    private String role;

    public Role() {
    }

    public Role(String role){
        this.role = role;
    }

    @Id
    @GeneratedValue
    public int getId() {
        return id;
    }

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

    @ManyToOne
    @JoinColumn(name="user_id")
    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }

    @Override
    public String getAuthority() {
        return this.role;
    }

    @Basic
    @Column(name="role")
    public String getRole(){
        return this.role;
    }

    public void setRole(String role){
        this.role = role;
    }
}

Answer 1

我自己找到了解决方案。我将@Transient注释设置为所有方法，我不希望它不应该是表格中的列。

Answer 2

您必须将属性的所有注释替换为getter方法。

[org.hibernate.mapping.Column（当局）]
