[待解决问题]
我用Hibernate annotation从one方获取many方总是报 IllegalArgumentException异常？
我的sys_Module是一个自身关联的实体
表结构如下：
其中父模块的M_ParentID字段值为0，子模块通过M_ParentID字段关联父模块的ModuleID值,ModuleID自增型
字段M_ApplicationID和字段M_PageCode为联合主键
sys_Module类code如下：
1 @Entity 2 @Table(name="sys_Module") 3 public class SysModule implements java.io.Serializable { 4 5 private static final long serialVersionUID = 1L; 6 7 8 9 /** 10 * @hibernate.id 11 * generator-class="assigned" 12 * 13 */ 14 private SysModulePK comp_id;

其中是复合主键SysModulePK：
public class SysModulePK implements java.io.Serializable { private static final long serialVersionUID = 1L; /** * @hibernate.property * column="M_ApplicationID" * length="10" * */ private Long mapplicationId; /** * @hibernate.property * column="M_PageCode" * length="6" * */ private String mpageCode; /** * * @hibernate.property * column="M_ApplicationID" * length="10" * */ //@Column(name="M_ApplicationID",nullable=false,insertable = false, updatable = false) @Column(name="M_ApplicationID",nullable=false) public Long getMapplicationId() { return this.mapplicationId; } public void setMapplicationId(Long mapplicationId) { this.mapplicationId = mapplicationId; } /** * * @hibernate.property * column="M_PageCode" * length="6" * */ //@Column(name="M_PageCode",nullable=false,insertable = false, updatable = false) @Column(name="M_PageCode",nullable=false) public String getMpageCode() { return this.mpageCode; } public void setMpageCode(String mpageCode) { this.mpageCode = mpageCode; } // plumbing @Override public boolean equals(Object obj) { return reflectionEquals(this, obj); } @Override public int hashCode() { return reflectionHashCode(this); } @Override public String toString() { return reflectionToString(this); } }
当我load一个sysModule实体后（可以获取sysModule，不报下面的异常），再获取sysModule.getSubsysModules()时，总是报异常：
IllegalArgumentException occurred calling getter of com.hedgehog.domain.SysModulePK.mapplicationId
请问我的代码是哪里有问题？
我调试这个问题 三天了
