Neo4j无法设置java。lang.长场模型。权威id到模型。权威

Question

我试图让Neo4j工作，但我最终得到这个错误时，无论是试图得到一个实体，或坚持一个，不能弄清楚。

我的实体：

@NodeEntity
@public class Authority  {

public Authority() {
}

@Id
@GeneratedValue
private Long id;

@NotNull
@Size(min = 0, max = 50)
private String name;

public Long getId() {
    return id;
}

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

public String getName() {
    return name;
}

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

@Override
public String toString() {
    return "Authority{" +
        "name='" + name + '\'' +
        "}";
}

}

我所做的一切都是为了拯救权威

Authority authAdmin = new Authority();
authAdmin.setName(AuthoritiesConstants.ADMIN);
authAdmin = authorityRepository.save(authAdmin);

Answer 1

我在Spring Boot 2.0.0 M6上也遇到了同样的问题。通过恢复到2.0.0 M5使其正常工作。

请注意，M4有一个不同的问题，但M3也可以工作（虽然我看不出有什么理由回到任何比M5更远的地方）
