SpringBatch学习例子

1.建表sql

CREATE TABLE BATCH_JOB_INSTANCE  (
    JOB_INSTANCE_ID BIGINT  NOT NULL PRIMARY KEY ,
    VERSION BIGINT ,
    JOB_NAME VARCHAR(100) NOT NULL,
    JOB_KEY VARCHAR(32) NOT NULL,
    constraint JOB_INST_UN unique (JOB_NAME, JOB_KEY)
) ENGINE=InnoDB;
-- 该BATCH_JOB_EXECUTION表包含与该JobExecution对象相关的所有信息

    constraint JOB_INST_EXEC_FK foreign key (JOB_INSTANCE_ID)
    references BATCH_JOB_INSTANCE(JOB_INSTANCE_ID)

    constraint JOB_EXEC_PARAMS_FK foreign key (JOB_EXECUTION_ID)
    references BATCH_JOB_EXECUTION(JOB_EXECUTION_ID)
) ENGINE=InnoDB;
-- 该表包含与该StepExecution 对象相关的所有信息
CREATE TABLE BATCH_STEP_EXECUTION  (

    VERSION BIGINT NOT NULL,
    STEP_NAME VARCHAR(100) NOT NULL,
    JOB_EXECUTION_ID BIGINT NOT NULL,

    LAST_UPDATED DATETIME,
    constraint JOB_EXEC_STEP_FK foreign key (JOB_EXECUTION_ID)
    references BATCH_JOB_EXECUTION(JOB_EXECUTION_ID)
) ENGINE=InnoDB;
-- 该BATCH_STEP_EXECUTION_CONTEXT表包含ExecutionContext与Step相关的所有信息
CREATE TABLE BATCH_STEP_EXECUTION_CONTEXT  (
    STEP_EXECUTION_ID BIGINT NOT NULL PRIMARY KEY,
    SHORT_CONTEXT VARCHAR(2500) NOT NULL,
    SERIALIZED_CONTEXT TEXT ,
    constraint STEP_EXEC_CTX_FK foreign key (STEP_EXECUTION_ID)
    references BATCH_STEP_EXECUTION(STEP_EXECUTION_ID)
) ENGINE=InnoDB;
-- 该表包含ExecutionContext与Job相关的所有信息
CREATE TABLE BATCH_JOB_EXECUTION_CONTEXT  (

CREATE TABLE BATCH_STEP_EXECUTION_SEQ (
    ID BIGINT NOT NULL,
    UNIQUE_KEY CHAR(1) NOT NULL,
    constraint UNIQUE_KEY_UN unique (UNIQUE_KEY)
) ENGINE=InnoDB;
INSERT INTO BATCH_STEP_EXECUTION_SEQ (ID, UNIQUE_KEY) select * from (select 0 as ID, '0' as UNIQUE_KEY) as tmp where not exists(select * from BATCH_STEP_EXECUTION_SEQ);
CREATE TABLE BATCH_JOB_EXECUTION_SEQ (
    ID BIGINT NOT NULL,
    UNIQUE_KEY CHAR(1) NOT NULL,

) ENGINE=InnoDB;
INSERT INTO BATCH_JOB_SEQ (ID, UNIQUE_KEY) select * from (select 0 as ID, '0' as UNIQUE_KEY) as tmp where not exists(select * from BATCH_JOB_SEQ);


-- hsqldb
