JOOQ-列“ id”的類型為uuid，但表達式的類型為字符變化

Question

我遇到與JOOQ相關的問題。

---------
這是導致問題的我的“設置”。
表：

CREATE TABLE "public".xyz
(
  id UUID NOT NULL,
  CONSTRAINT pk_t_xyz PRIMARY KEY(id)
);

JOOQ生成的字段正確

public final TableField<XYZRecord, UUID> ID = createField("id", org.jooq.impl.SQLDataType.UUID.nullable(false), this, "comment");

UUID來自java.util.*

我的“自定義” POJO具有來自java.util.* UUID：

public class XYZ {

    @NotNull
    private UUID id;

    public XYZ (@NotNull UUID id) {
        this.id = id;
    }

    public UUID getId() {
        return id;
    }
}

DSL配置：

@Configuration
public class DataSourceConfiguration {

    @Qualifier("dataSource")
    @Autowired
    private DataSource dataSource;

    @Bean
    public DefaultDSLContext dsl() {
        return new DefaultDSLContext(configuration());
    }

    @Bean
    public DataSourceConnectionProvider connectionProvider() {
        return new DataSourceConnectionProvider
            (new TransactionAwareDataSourceProxy(dataSource));
    }

    public DefaultConfiguration configuration() {
        DefaultConfiguration jooqConfiguration = new DefaultConfiguration();
        jooqConfiguration.set(connectionProvider());
        jooqConfiguration.set(new DefaultExecuteListenerProvider(exceptionTransformer()));
        return jooqConfiguration;
    }

    @Bean
    public ExceptionTranslator exceptionTransformer() {
        return new ExceptionTranslator();
    }
}

application.yml中的數據源

spring:
  datasource:
    type: com.zaxxer.hikari.HikariDataSource
    driver-class-name: org.postgresql.Driver
    url: jdbc:postgresql://localhost:5432/xyz-data

jooq的版本是3.10.5。 我在spring-boot-starter-jooq版本2.0.0.RELEASE spring-boot-starter-jooq與spring boot 2.0.0.RELEASE 。 PostgresSQL版本為10。
------------------
當我嘗試像這樣插入數據時：

    dslContext.insertInto(XYZ, XYZ.ID)
        .values(xyz.getId()).execute();

由於某種原因，它不起作用。 從下面的異常可以理解，JOOQ正在將UUID強制轉換為字符串，因此SQL無效。 我應該編寫某種轉換器還是以錯誤的方式定義某些內容？

錯誤：

org.springframework.jdbc.BadSqlGrammarException: Access database using jOOQ; bad SQL grammar [insert into "public"."xyz" ("id") values (?)]; nested exception is org.postgresql.util.PSQLException: ERROR: column "id" is of type uuid but expression is of type character varying

Answer 1

我在Spring Boot中遇到了這個確切的問題。 我可以通過在設置DefaultConfiguration對象時顯式指定Postgres方言來解決此問題。

例如，在您的DSL配置中：

public DefaultConfiguration configuration() {
    DefaultConfiguration jooqConfiguration = new DefaultConfiguration();

    // Explicitly set the Dialect
    jooqConfiguration.setSQLDialect(SQLDialect.POSTGRES);

    jooqConfiguration.set(connectionProvider());
    jooqConfiguration.set(new DefaultExecuteListenerProvider(exceptionTransformer()));
    return jooqConfiguration;
}

這是jOOQ中的錯誤： https ： //github.com/jOOQ/jOOQ/issues/7351

似乎僅當將null值綁定為UUID時才會發生。 解決方法是實現您自己的數據類型綁定： https : //www.jooq.org/doc/latest/manual/sql-building/queryparts/custom-bindings
