我面临着一个严重的问题，关于复合键与休眠4.3.9 Final和c3p0 4.3.8。休眠 - 嵌入式类的复合键
首先，我想给你我的实体答我的数据库Relationsships有点概述。
的重要表：
CREATE TABLE `TrainingplanHistory` (
`TrainingplanID` int(11) NOT NULL,
`time` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
PRIMARY KEY (`TrainingplanID`,`time`),
CONSTRAINT `fk_trainingplanHistory_trainingplan` FOREIGN KEY (`TrainingplanID`) REFERENCES `Trainingplan` (`TrainingplanID`) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB DEFAULT CHARSET=latin1
CREATE TABLE `TrainingplanHistoryExercises` (
`TrainingplanID` int(11) NOT NULL,
`ExerciseID` int(11) NOT NULL,
`Time` datetime NOT NULL,
`ParameterID` int(11) NOT NULL,
`value` varchar(45) NOT NULL,
`position` int(11) NOT NULL,
PRIMARY KEY (`TrainingplanID`,`Time`,`ParameterID`,`position`),
KEY `fk_trainingplanhistory_exercises_trainingplanhistory_idx` (`TrainingplanID`,`Time`),
KEY `fk_trainingplanhsitoryexercises_exercises_idx` (`ExerciseID`),
KEY `fk_trainingplanhsitoryexercises_exercises_parameter_idx` (`ExerciseID`,`ParameterID`),
CONSTRAINT `fk_trainingplanhistory_exercises_trainingplanhistory` FOREIGN KEY (`TrainingplanID`, `Time`) REFERENCES `TrainingplanHistory` (`TrainingplanID`, `time`) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB DEFAULT CHARSET=latin1
我的数据Java中的类：
TrainingplanHistory.java
package beans;
import javax.persistence.*;
import java.util.Date;
/**

@Entity
@Table(name="TrainingplanHistory")

}
}
TrainingplanHistoryId.java

public TrainingplanHistoryId()

}
本准则与conmposite键“TrainingplanID”和“时间”的作品非常好，但我的主要问题是， “时间”是一个外键，也是我的表格训练计划历史练习中的主键。
因此我写此代码：

我的问题是，我的应用程序无法启动，由于一些贴图错误我猜。
