Spring batch 没有枚举常量类org.springframework.batch.core.JobParameter$ParameterType.DATE-Informix

因此，我正在Informix数据库中设置一个持久的spring批处理v2.2.2作业repo。我已经调整了oracle sql脚本，并使用此sql创建了“批处理作业执行参数”表-注意，“日期”列映射到“日期”

CREATE TABLE 'dba'.BATCH_JOB_EXECUTION_PARAMS  (
JOB_EXECUTION_ID INTEGER NOT NULL ,
TYPE_CD CHAR(6) NOT NULL ,
KEY_NAME CHAR(100) NOT NULL ,
STRING_VAL CHAR(250) ,
DATE_VAL DATE DEFAULT NULL ,
LONG_VAL INTEGER ,
DOUBLE_VAL DOUBLE PRECISION ,
IDENTIFYING CHAR(1) NOT NULL ,
foreign key (JOB_EXECUTION_ID)
references BATCH_JOB_EXECUTION(JOB_EXECUTION_ID)
constraint JOB_EXEC_PARAMS_FK 
);

我运行了第一个作业，可以在表中看到这一行

job_execution_id    type_cd key_name    string_val  date_val    long_val    double_val  identifying
2   DATE    RUN_DATE        05/12/2013  0   0.0 Y

但是我的代码失败了，出现了这个异常。有人知道为什么日期的“type_cd”值不能映射到枚举类型吗

由于CHAR6类型的填充空格。改用VARCHAR，一切都会好起来的。 在日志中选择从.DATE到行尾的文本，您将注意到额外的空格：
