Java Hibernate左联接中的联接错误所需的路径

的Hibernate查询给了我以下错误

FROM RecordItems t1
LEFT JOIN PropertyValues t2 where t2.property = 'age'ORDER BY CASE WHEN t2.value IS NULL THEN 1 ELSE 0 END, t2.value

异常：预期加入的路径

异常：意外标记：位于第1行附近

下面提供了Hibernate映射和实体详细信息：

public class RecordItems implements java.io.Serializable {
     private Integer id;
     private String col1;
     private String col2;
     private String col3;
}
public class PropertyValues implements java.io.Serializable {
     private Integer id;
     private RecordItems REC;
     private String property;
     private String value;

}

公共类RecordItems实现java.io.Serializable{

HQL适用于对象结构，而不是表结构。它必须类似于：FROM RecordItems t1 LEFT JOIN t1。。但是如果不知道您的实体，很难说我的Hibernate对象使用与表列名相同的名称。我将在Descriptione中提供对象详细信息，即使我没有给出where和order子句，我也会从t1上的RecordItems t1 LEFT JOIN Property Value t2中得到此错误。id=t2。请准确地重新读取我的注释

LEFT JOIN t1对象的hibernate映射在哪里？
public class RecordItems implements java.io.Serializable {
     private Integer id;
     private String col1;
     private String col2;
     private String col3;
}
public class PropertyValues implements java.io.Serializable {
     private Integer id;
     private RecordItems REC;
     private String property;
     private String value;
