java - JOOQ 在获取表元数据时抛出 DataTypeException

Question

尝试获取表元数据时出错。
使用:
JOOQ 3.14.0,
PostgeSQL 12,
PostgreSQL 驱动程序 42.2.10
例子:

@RestController
@ApiVersion("v2")
public class TypeResource {
    private final DSLContext ctx;

    @GetMapping(value = "/test")
    public void test(@RequestParam String table) {
        ctx.meta().getTables(table);
    }
}

错误(这不是整个错误，但其余类似):

示例表创建脚本:

CREATE TABLE public.user_role
(
    id bigint NOT NULL DEFAULT nextval('user_role_id_seq'::regclass),
    user_id bigint NOT NULL,
    role_id bigint NOT NULL,
    ts_created timestamp without time zone NOT NULL DEFAULT CURRENT_TIMESTAMP,
    ts_updated timestamp without time zone NOT NULL DEFAULT CURRENT_TIMESTAMP,
    updated_by_user character varying(256) COLLATE pg_catalog."default" NOT NULL DEFAULT 'n/a'::character varying,
    updated_by_process character varying(64) COLLATE pg_catalog."default" NOT NULL DEFAULT 'n/a'::character varying,
    CONSTRAINT user_role_pkey PRIMARY KEY (id),
    CONSTRAINT x_role_id_fk FOREIGN KEY (role_id)
        REFERENCES public.role (id) MATCH FULL
        ON UPDATE NO ACTION
        ON DELETE NO ACTION,
    CONSTRAINT x_user_id_fk FOREIGN KEY (user_id)
        REFERENCES public."user" (id) MATCH FULL
        ON UPDATE NO ACTION
        ON DELETE NO ACTION
)

TABLESPACE pg_default;

ALTER TABLE public.user_role
    OWNER to postgres;

CREATE UNIQUE INDEX x_role_user_id_role_id_uq
    ON public.user_role USING btree
    (user_id ASC NULLS LAST, role_id ASC NULLS LAST)
    TABLESPACE pg_default;

最初我的目标是获取表索引，这工作正常。
我尝试将 JOOQ 从 3.13.1 更新到 3.14.0 并使用数据库中的不同表进行测试，但没有任何运气。

这是一个错误，将在 jOOQ 3.15 中通过 https://github.com/jOOQ/jOOQ/issues/8469 修复. jOOQ 当前假设 DatabaseMetaData列描述为 DEFAULT 生成值表达式，而不是表达式。
该错误是“装饰性的”，因为它只会影响您的日志。该字段仍然正确生成(没有任何 DEFAULT 表达式)。您可以在记录器配置中静音消息，直到上述错误得到修复。
