CREATE TABLE public."PROPERTIES"
(
    "APPLICATION" character varying(500) COLLATE pg_catalog."default",
    "PROFILE" character varying(500) COLLATE pg_catalog."default",
    "LABEL" character varying(500) COLLATE pg_catalog."default",
    "KEY" character varying(500) COLLATE pg_catalog."default",
    "VALUE" character varying(500) COLLATE pg_catalog."default"
)

INSERT INTO public."PROPERTIES"
("APPLICATION", "PROFILE", "LABEL", "KEY", "VALUE")
VALUES('discovery-service', '', '', 'spring.application.name', 'discovery-service');
INSERT INTO public."PROPERTIES"
("APPLICATION", "PROFILE", "LABEL", "KEY", "VALUE")
VALUES('discovery-service', '', '', 'server.port', '8761');

Answer 1

PSQLException说“properties”不存在是因为PostgreSQL区分大小写。当使用PGAdmin创建表/列时，如果名称都是大小写，该工具会自动添加引号，从而使其区分大小写。

您可以尝试以下方法：

CREATE TABLE public.properties
(
    application character varying(50) COLLATE pg_catalog."default",
    profile character varying(50) COLLATE pg_catalog."default",
    label character varying(50) COLLATE pg_catalog."default",
    key character varying(50) COLLATE pg_catalog."default",
    value character varying(500) COLLATE pg_catalog."default"
)

INSERT INTO properties
("application", "profile", "label", "key", "value")
VALUES('myconfig', 'default', 'master', 'my.message', 'hello');

Application.Properties包含：

server.port=8888
spring.profiles.active=jdbc
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.url= jdbc:postgresql://localhost:5432/configdb
spring.datasource.username=xxxxxx
spring.datasource.password=xxxxxx
