InputSub.java

public class InputSub implements Serializable {
	
	private Integer id;
	private String telephone;
	private String epno;	//关联GisEpstat Entity的字段
	private String simno;
	private Integer inputEpId;
	private InputEp inputEp;
	private String onlineType;
	private String onlineTime;
	
	private InputEp inputep;
	private GisEpstat gisepstat; //定义GisEpstat 
        getter/setter
}

InputSub.hbm.xml

<hibernate-mapping>
    <class name="com.agric.common.entity.InputSub" table="input_sub" catalog="antongdb">

            <generator class="identity" />
        </id>
          .

      		<column name="epno"></column>
      	</many-to-one>
      	
    </class>
</hibernate-mapping>

GisEpstat.java

public class GisEpstat implements java.io.Serializable {

	private static final long serialVersionUID = 1L;
	private Integer id;
	private String epid;
        getter/setter
}

GisEpstat.hbm.xml

<hibernate-mapping>
    <class name="com.agric.common.entity.GisEpstat" table="gis_epstat">
        <id name="id" type="java.lang.Integer">
            <column name="id" />
            <generator class="identity" />
        </id>
        <property name="epid" type="java.lang.String">
            <column name="epid" length="20" not-null="true" unique="true" />
        </property>
 </class>
</hibernate-mapping>

InputDao.java 查询

	public List<InputSub> getSelect(){
...
	try {
			listsub = super.getByPage(hql, page, pageSize);
			
		} catch (Exception ex) {
			ex.printStackTrace();
			System.out.println("根据条件获取农机信息出现错误！");
		}
		
		if(gps==null){
			
			for(int i=listsub.size()-1;i>=0;i--){
				System.out.println(listsub.get(i).getGisepstat()==null);
				System.out.println(listsub.get(i).getGisepstat());
				
				if(listsub.get(i).getGisepstat()==null){
					listsub.remove(i);
				}else{
					System.out.println("---"+listsub.get(i).getGisepstat());
				}
				
			}
		}
...
}

listsub 都有值，但是listsub.get(i).getGisepstat()是空的，解解，帮看看配置文件是否有问题

什么叫非主键的关联？epno不是GisEpstat的主键？
