Spring 在Liquibase映射数据库中找不到列

尝试在spring boot应用程序上运行测试时，出现以下异常：

org.hibernate.tool.schema.spi.SchemaManagementException： 架构验证：表[T_ANSWER]中缺少列[value]

我的配置如下所示：

@Bean(destroyMethod = "shutdown")
    @Profile("!" + Constants.SPRING_PROFILE_CLOUD)
    public DataSource dataSource() {
        log.debug("Configuring Datasource");
        if (propertyResolver.getProperty("url") == null && propertyResolver.getProperty("databaseName") == null) {
            log.error("Your database connection pool configuration is incorrect! The application" +
                    "cannot start. Please check your Spring profile, current profiles are: {}",
                    Arrays.toString(env.getActiveProfiles()));

            throw new ApplicationContextException("Database connection pool is not configured correctly");
        }
        HikariConfig config = new HikariConfig();
        config.setDataSourceClassName(propertyResolver.getProperty("dataSourceClassName"));
        if (propertyResolver.getProperty("url") == null || "".equals(propertyResolver.getProperty("url"))) {
            config.addDataSourceProperty("databaseName", propertyResolver.getProperty("databaseName"));
            config.addDataSourceProperty("serverName", propertyResolver.getProperty("serverName"));
        } else {
            config.addDataSourceProperty("url", propertyResolver.getProperty("url"));
        }
        config.addDataSourceProperty("user", propertyResolver.getProperty("username"));
        config.addDataSourceProperty("password", propertyResolver.getProperty("password"));

        //MySQL optimizations, see https://github.com/brettwooldridge/HikariCP/wiki/MySQL-Configuration
        if ("com.mysql.jdbc.jdbc2.optional.MysqlDataSource".equals(propertyResolver.getProperty("dataSourceClassName"))) {
            config.addDataSourceProperty("cachePrepStmts", propertyResolver.getProperty("cachePrepStmts", "true"));
            config.addDataSourceProperty("prepStmtCacheSize", propertyResolver.getProperty("prepStmtCacheSize", "250"));
            config.addDataSourceProperty("prepStmtCacheSqlLimit", propertyResolver.getProperty("prepStmtCacheSqlLimit", "2048"));
            config.addDataSourceProperty("useServerPrepStmts", propertyResolver.getProperty("useServerPrepStmts", "true"));
        }
        return new HikariDataSource(config);
    }


  @Bean
  public SpringLiquibase liquibase(DataSource dataSource) {
    SpringLiquibase liquibase = new SpringLiquibase();
    liquibase.setDataSource(dataSource);
    liquibase.setChangeLog("classpath:config/liquibase/master.xml");
    liquibase.setContexts("development, production");
    if (env.acceptsProfiles(Constants.SPRING_PROFILE_FAST)) {
      if ("org.h2.jdbcx.JdbcDataSource".equals(propertyResolver.getProperty("dataSourceClassName"))) {
        liquibase.setShouldRun(true);
        log.warn("Using '{}' profile with H2 database in memory is not optimal, you should consider switching to" +
          " MySQL or Postgresql to avoid rebuilding your database upon each start.", Constants.SPRING_PROFILE_FAST);
      } else {
        liquibase.setShouldRun(false);
      }
    } else {
      log.debug("Configuring Liquibase");
    }
    return liquibase;
  }



    @Bean
    public Hibernate4Module hibernate4Module() {
        return new Hibernate4Module();
    }

我的配置文件如下所示：

spring:
    profiles:
        active: dev

    datasource:
        dataSourceClassName: org.h2.jdbcx.JdbcDataSource
        url: jdbc:h2:mem:questionnaires;DB_CLOSE_DELAY=-1
        databaseName:
        serverName:
        username:
        password:

    jpa:
        database-platform: org.hibernate.dialect.H2Dialect
        database: H2
        openInView: false
        show_sql: true
        properties:
            hibernate.cache.use_second_level_cache: true
            hibernate.cache.use_query_cache: false
            hibernate.generate_statistics: true
            hibernate.hbm2ddl.auto: update
            hibernate.cache.region.factory_class: org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory

导致问题的实体称为Answer，它没有值属性，但它的一些子实体有值属性，下面是实体和相关子实体的实现

答复:

 @Entity
@Table(name = "T_ANSWER")
public abstract class Answer {
    @Id
    @GeneratedValue(strategy= GenerationType.AUTO)
    private long id;

    private String innerID;

    public Answer(){
        innerID = UUID.randomUUID().toString();
    }



    @ManyToOne
    private AnswerTab parentTab;

    public String getInnerID() {
        return innerID;
    }

    public void setInnerID(String innerID) {
        this.innerID = innerID;
    }

    public long getId() {
        return id;
    }

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

    public AnswerTab getParentTab() {
        return parentTab;
    }

    public void setParentTab(AnswerTab parentTab) {
        this.parentTab = parentTab;
    }
}

以及具有value属性的子级：

@Entity
@Table(name = "T_SINGLEANSWER")
public class SingleAnswer extends Answer{


    private String value = "";

    @ManyToOne
    private AnswerRow parentRow;



    public SingleAnswer(){

    }


    public String getValue() {
        return value;
    }

    public void setValue(String value) {
        this.value = value;
    }

    public AnswerRow getParentRow() {
        return parentRow;
    }

    public void setParentRow(AnswerRow parentRow) {
        this.parentRow = parentRow;
    }

    @Override
    public Answer copy() {
        SingleAnswer copy = new SingleAnswer();
        copy.setInnerID(getInnerID());
        copy.setValue(value);
        return copy;
    }


    @Override
    public boolean equals(Object obj) {
        if(obj instanceof SingleAnswer){
            return value.compareTo(((SingleAnswer)obj).getValue()) == 0;
        }
        return super.equals(obj);
    }
}

我检查了生成的数据库，可以清楚地看到表T_ANSWER有一个value属性

以下是创建表的liquibase变更集：

<createTable tableName="t_answer">
    <column name="DTYPE" type="VARCHAR(31)">
        <constraints nullable="false"/>
    </column>
    <column autoIncrement="true" name="id" type="BIGINT(19)">
        <constraints primaryKey="true"/>
    </column>
    <column name="innerID" type="VARCHAR(255)"/>
    <column name="value" type="VARCHAR(255)"/>
    <column name="dynamic" type="BIT(1)"/>
    <column name="size" type="INT(10)"/>
    <column name="parentTab_id" type="BIGINT(19)"/>
    <column name="parentRow_id" type="BIGINT(19)"/>
    <column name="parentGroup_id" type="BIGINT(19)"/>
</createTable>

我也面临同样的问题。这是由于表属性名称的大小写不同造成的。对我来说，通过替换下面的代码，它就消失了。我在db-config.properties文件中更改了它

spring.jpa.hibernate.ddl-auto:validate

到

spring.jpa.hibernate.ddl-auto:update

---

注意：无论您使用的是spring boot还是spring元数据配置文件（xml），它都会工作。

我认为导致此异常的原因是

value

是Mysql中的保留关键字（考虑到您使用的是Mysql），在这种情况下，您必须在

value

的getter上添加

@Column

注释，比如：

@Column（name=“[VALUE]”，nullable=false）

谢谢你，这就是问题所在，我在删除它时发现了它，我开始在名为dynamic的列中看到同样的问题
