Neo4j 无法将 java.lang.Long 字段 model.Authority.id 设置为 model.Authority

Question

我正在尝试让 Neo4j 工作，但在尝试获取实体或保留实体时我最终遇到了这个错误，但无法弄清楚。

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() {

}

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

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

}

我想做的就是保存授权

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

Answer 1

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

注意 M4 有一个不同的问题，但 M3 也可以（尽管我认为没有理由比 M5 更进一步）

Neo4j 无法将 java.lang.Long 字段 model.Authority.id 设置为 model.Authority

Neo4j Can not set java.lang.Long field model.Authority.id to model.Authority

neo4j

maven-3

spring-boot
