这意味着UPDATE的话,你总是得UPDATE所有的字段.你得把所有的字段值全SET到实体中才行.

直接用框架生成的update方法,它会自动生成SQL,不用自己写,排他就好用.

@S2Dao(bean = UsodMCustomMailEntity.class)
public interface UsodMCustomMailDao extends BaseDao {
    @Arguments("entity")
    public int update(UsodMCustomMailEntity entity);
}

@Bean(table = "usod_m_custom_mail", timeStampProperty = "timestamp")
public class UsodMCustomMailEntity extends BaseEntity {
    @Column("template_id")
    public String templateId;

    @Column("template_name")
    public String templateName;

    @Column("description")
    public String description;

    @Column("mail_from")
    public String mailFrom;

    @Column("mail_to")
    public String mailTo;

    ．．．省略．．．

    @Column("last_update_date")
    public Timestamp timestamp;
}
