jhipster在现有实体中添加新属性

Question

我使用的是jhipster 4.0.0，我首先创建了两个实体

@Entity
@Table(name = "organization")
@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
public class Organization implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(name = "orgname")
    private String orgname;

    @Column(name = "orgaddress")
    private String orgaddress;

    @OneToMany(mappedBy = "organization")
    @JsonIgnore
    @Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
    private Set<Branch> branches = new HashSet<>();

//geter()
//setter()

}

和

@Entity
@Table(name = "branch")
@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
public class Branch implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(name = "branchname")
    private String branchname;

    @Column(name = "branchaddress")
    private String branchaddress;

    @ManyToOne
    private Organization organization;

    //geter()
    //setter()

    }

这两个都很好用，现在我向组织实体添加了一个名为Active的新属性，如下所示

>yo jhipster:entity organization

当我运行我的项目时。/mvnw

它显示的错误如下

liquibase.exception.ValidationFailedException: Validation Failed:
     1 change sets check sum
          classpath:config/liquibase/changelog/20170209093838_added_entity_Organization.xml::20170209093838-1::jhipster was: 7:2b47689e3924d85d502e6150230cd184 but is now: 7:74e4a48710ed8eaf27e2a0231f7d23a9

我也尝试了这个给出的所有解决方案

How to modify existing entity generated with jhipster?

当我运行mvn liquibase:diff after change时，我得到的结果如下所示

有人能帮帮我吗？

Answer 1

您需要在pom.xml中为liquibase maven-plugin设置数据库用户名和密码

Answer 2

当我们在pom.xml中更改数据库用户名和密码时，请使用liquibase maven-plugin。

 <plugin>
                    <groupId>org.liquibase</groupId>
                    <artifactId>liquibase-maven-plugin</artifactId>

                        <diffChangeLogFile>src/main/resources/config/liquibase/changelog/${maven.build.timestamp}_changelog.xml</diffChangeLogFile>
                        <driver>com.mysql.jdbc.Driver</driver>

                        </dependency>
                        <dependency>
                            <groupId>org.liquibase.ext</groupId>
                            <artifactId>liquibase-hibernate5</artifactId>
                            <version>${liquibase-hibernate5.version}</version>
                        </dependency>
                        <dependency>

                            <version>1.1.0.Final</version>
                        </dependency>
                    </dependencies>
                </plugin>

在那之后我们得跑

./mvnw liquibase:clearCheckSums



./mvn liquibase:diff

之后，在src/main/resources/config/liquibase/changelog目录中创建新的“更改日志”。该目录中的文件以其创建日期( yyyyMMddHHmmss格式)为前缀，然后有一个标题来描述它们的功能。例如，20141006152300_added_price_to_product.xml是一个好名字。将这个“更改日志”文件添加到您的src/main/resources/config/liquibase/master.xml文件中，以便在您下次运行应用程序时，如果您需要有关使用Liquibase的更多信息，就可以应用它
