使用'fetch.into（MyClass.class）'时jOOQ配置为null

标签： java spring-boot jooq

我需要升级我的应用程序中的Gradle和一些软件包，但是在那之后，Spring Boot或jOOQ似乎并没有加载它的配置或类似的东西。

Build.gradle重要部分：

...
plugins {
    id 'java'
    id 'idea'
    id 'nu.studer.jooq' version '3.0.3'
    id 'org.springframework.boot' version '2.2.1.RELEASE'
}


dependencies {
    compile group: 'org.springframework.boot', name: 'spring-boot-starter', version: '2.2.1.RELEASE'
    compile group: 'org.springframework.boot', name: 'spring-boot-starter-jooq', version: '2.2.1.RELEASE'

    compile group: 'com.zaxxer', name: 'HikariCP', version: '3.4.1'
    compile group: 'org.firebirdsql.jdbc', name: 'jaybird-jdk18', version: '2.2.12'
    compile group: 'org.jooq', name: 'jooq', version: '3.12.3'
    compile group: 'org.jooq', name: 'jooq-codegen', version: '3.12.3'

    jooqRuntime 'org.firebirdsql.jdbc:jaybird-jdk18:2.2.12'
}


ext['jooq.version'] = '3.12.3'
...

这是我要执行的代码：

List<LinhaRelatoFichaProduto> notas =
        dsl.selectFrom(notasEntrada.unionAll(notasSaida).asTable())
                .orderBy(field(name("data")),
                        field(name("tipo")),
                        field(name("numero")),
                        field(name("datahora"))
                ).fetch().into(LinhaRelatoFichaProduto.class);

但是我在这行得到一个NullPointerException：

@Override
        public final <R extends Record, E> RecordMapper<R, E> provide(final RecordType<R> rowType, final Class<? extends E> type) {
            if (TRUE.equals(configuration.settings().isCacheRecordMappers()))    << HERE! configuration is null for some reason
                return Cache.run(configuration, new CachedOperation<RecordMapper<R, E>>() {
                    @Override
                    public RecordMapper<R, E> call() {
                        return new DefaultRecordMapper<R, E>(rowType, type, configuration);
                    }
                }, DATA_CACHE_RECORD_MAPPERS, Cache.key(rowType, type));
            else
                return new DefaultRecordMapper<R, E>(rowType, type, configuration);
        }

这是完整的错误堆栈：

            else
                return new DefaultRecordMapper<R, E>(rowType, type, configuration);
        }

我的自定义DSL上下文：

@Configuration
public class FirebirdJooqConfiguration {

    @Bean(name = "firebirdDSLContext")
    public DSLContext firebirdDSLContext(@Qualifier("firebirdDataSource") DataSource dataSource) {
        return DSL.using(new DefaultConfiguration()
                .set(dataSource)
                .set(SQLDialect.FIREBIRD)
                .set(new DefaultExecuteListenerProvider(new JooqExceptionTransformer()))
                .set(new DefaultRecordMapperProvider()));
    }

}

那么...如何避免jOOQ配置为空？

那是jOOQ中的一个错误：https://github.com/jOOQ/jOOQ/issues/9621

从DefaultRecordMapperProvider中删除Configuration，它应该可以工作：

@Bean(name = "firebirdDSLContext")
public DSLContext firebirdDSLContext(@Qualifier("firebirdDataSource") DataSource dataSource) {
    return DSL.using(new DefaultConfiguration()
            .set(dataSource)
            .set(SQLDialect.FIREBIRD)
            .set(new DefaultExecuteListenerProvider(new JooqExceptionTransformer()))
         /* .set(new DefaultRecordMapperProvider()) */ );
}
