最重要的一句, ERROR org.hibernate.engine.jdbc.spi.SqlExceptionHelper No value specified for parameter 1
Caused by: java.sql.SQLException: No value specified for parameter 1
说的啥,无法给第一个参数赋值
网上查一大堆,都是说自己问号和实际参数数量不对,我检查了之后发现并不是这样,参数个数和问号占位符数量是一致的,也是很简单用BaseRepository的saveAndFlush来保存实体,
那为什么会报错呢,数据库里主键自增其实是不需要传id的,我检查了数据库也没发现什么问题
翻来覆去寻找
最终找到了一句 line 1:106 no viable alternative at input '(code,face_code,factory,ip,name,password,port,pos,remark,serial_id,source'
说的什么输入时没有可行的替代方案,但是我看到,从source开始往后的参数没了?那是不是这个source的问题呢,可能是数据库关键字冲突,于是我在实体的source属性上添加了指定列名
@Column(name = "[source]") private int source;
就是这个,指定了列名为source
再执行添加/插入数据就不报错了
关键字冲突就关键字冲突嘛,报参数问题,谁一眼能看出来
记录一下
