我正在尝试使用 Glassfish 提供的计时器服务。因此，我必须EJB__TIMER__TBL在 Glassfish 中创建一个名为并配置 jdbc 资源的表。

我想将此表存储在 postgreSQL 上名为glassfish. 所以我的 ddl 就是这个（我将BLOB类型替换为BYTEA）：

CREATE SCHEMA glassfish;

CREATE TABLE glassfish.EJB__TIMER__TBL (
    CREATIONTIMERAW      BIGINT        NOT NULL,
    BLOB                 BYTEA,
    TIMERID              VARCHAR(255)  NOT NULL,
    CONTAINERID          BIGINT        NOT NULL,
    OWNERID              VARCHAR(255)  NULL,
    STATE                INTEGER       NOT NULL,
    PKHASHCODE           INTEGER       NOT NULL,
    INTERVALDURATION     BIGINT        NOT NULL,
    INITIALEXPIRATIONRAW BIGINT        NOT NULL,
    LASTEXPIRATIONRAW    BIGINT        NOT NULL,
    SCHEDULE             VARCHAR(255)  NULL,
    APPLICATIONID        BIGINT        NOT NULL,
    CONSTRAINT PK_EJB__TIMER__TBL PRIMARY KEY (TIMERID) 
);

DROP ROLE IF EXISTS glassfish;                      
CREATE ROLE glassfish WITH NOINHERIT LOGIN PASSWORD '...';
REVOKE ALL PRIVILEGES ON ALL TABLES IN SCHEMA glassfish FROM glassfish;
REVOKE ALL PRIVILEGES ON ALL FUNCTIONS IN SCHEMA glassfish FROM glassfish;
GRANT USAGE ON SCHEMA glassfish TO glassfish;
GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA glassfish TO glassfish;
GRANT EXECUTE ON ALL FUNCTIONS IN SCHEMA glassfish TO glassfish;
GRANT USAGE ON ALL SEQUENCES IN SCHEMA glassfish TO glassfish;
ALTER USER glassfish SET search_path to 'glassfish';

我为 Glassfish 配置了一个 jdbc 池和资源：

asadmin create-jdbc-connection-pool 
--datasourceclassname org.postgresql.ds.PGConnectionPoolDataSource 
--restype javax.sql.ConnectionPoolDataSource 
--property User=glassfish:Password=...:PortNumber=5432:DatabaseName=...:ServerName=localhost jdbc/simPool/glassfish


asadmin create-jdbc-resource --connectionpoolid jdbc/simPool/glassfish jdbc/sim/glassfish

我正确输入jdbc/sim/glassfish了 jdbc 资源以用于 Glassish GUI 中的计时器服务。

每次我部署我的应用程序时，我都会收到 Exception ：

EJB__TIMER__TBL所以Glassfish 似乎无法访问我的桌子。

当我创建另一个项目时，使用persistence.xml与我上面的池连接相同的凭据配置一个文件并创建一个简单的查询SELECT COUNT(*) FROM EJB__TIMER__TBL，我收到0所以我的连接已经建立，并且访问的默认模式与预期的glassfish一样。

里面有一些ddls，但postgresql都没有……那我在${glassfish_root}\glassfish\lib\install\databases哪里做错了？

注意：当我测试使用 MySQL jdbc 资源配置服务计时器时，它的工作...

感谢帮助

好的，我找到了我的问题的解决方案。

我不知道 SQL 可以是case sensitive. GlassfishSELECT ... FROM "EJB__TIMER__TBL"使用双引号调用，因此我必须创建一个名为“EJB__TIMER__TBL”的表，而不是“ejb__timer__tbl”或其他任何名称。

解决方法就是用双引号重新创建我的表：

CREATE TABLE glassfish."EJB__TIMER__TBL" (
"CREATIONTIMERAW"      BIGINT        NOT NULL,
"BLOB"                 BYTEA,
"TIMERID"              VARCHAR(255)  NOT NULL,
"CONTAINERID"          BIGINT        NOT NULL,
"OWNERID"              VARCHAR(255)  NULL,
"STATE"                INTEGER       NOT NULL,
"PKHASHCODE"           INTEGER       NOT NULL,
"INTERVALDURATION"     BIGINT        NOT NULL,
"INITIALEXPIRATIONRAW" BIGINT        NOT NULL,
"LASTEXPIRATIONRAW"    BIGINT        NOT NULL,
"SCHEDULE"             VARCHAR(255)  NULL,
"APPLICATIONID"        BIGINT        NOT NULL,
CONSTRAINT "PK_EJB__TIMER__TBL" PRIMARY KEY ("TIMERID") 
);
