用Spring调试程序的时候出现如下错误：当时的环境是：Struts2.1 Spring3.1 Oracle9i 用到的表Persion的定义： create table PERSON ( PER_ID NUMBER not null, NAME NVARCHAR2(20), GENDER NVARCHAR2(6) ) tablespace USERS pctfree 10 initrans 1 maxtrans 255 storage ( initial 64 minextents 1 maxextents unlimited ); -- Create/Recreate primary, unique and foreign key constraints alter table PERSON add constraint PER_ID primary key (PER_ID) using index tablespace USERS pctfree 10 initrans 2 maxtrans 255 storage ( initial 64K minextents 1 maxextents unlimited ); 其中PER_ID 我定义了一个序列： create sequence PERSON_ID_SEQ minvalue 1 maxvalue 1000000000 start with 11 increment by 1 nocache; 然后用一个触发器将这个序列和PER_ID列关联起来： create or replace trigger bi_person_id before insert on person for each row declare nextid number; begin if :new.per_id is NULL or :new.per_id = 0 then select PERSON_ID_SEQ.nextval into nextid from dual; :new.per_id := nextid; end if; end bi_person_id; 用到的配置文件： hibernate.cfg.xml Person.hbm.xml 执行插入操作时就报上面的错误，然后我把Person.hbm.xml中的<generator class="identity"/>给删掉就好了
