场景简介

1、程序将mybatis框架升级为3.5.9版本 后执行updateByExample方法时报错

代码片断

java 复制代码 
Condition condition = new Condition(MbCcsSessionConfig.class);
condition.createCriteria().andEqualTo("vdnId", SecurityAuthenUtil.getVdnId());
int row = mbCcsSessionConfigService.updateByExample(param, condition);

实体类

java 复制代码 
@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
@Table(name = "t_mb_ccs_session_config")
public class MbCcsSessionConfig  {
	
	private static final long serialVersionUID = 1L;
	
	@Id
	@Column(name = "vdnId")
	private Integer vdnId;
	
	@Column(name = "sessionExceptionOverTime")
	private Integer sessionExceptionOverTime = 10;
	
	@Column(name = "sessionExceptionAgentOverTime")
	private Integer sessionExceptionAgentOverTime = 30;
	
	@Column(name = "sessionExceptionOpenOverTime")
	private Integer sessionExceptionOpenOverTime = 20;
	
	@Column(name = "sessionNoStaffOverTime")
	private Integer sessionNoStaffOverTime = 5;
	
	@Column(name = "leaveSessionOverTime")
	private Integer leaveSessionOverTime = 50;
	
	@Column(name = "leaveAgentOverTime")
	private Integer leaveAgentOverTime = 3;
	
	@Column(name = "sessionQueueOverTime")
	private Integer sessionQueueOverTime = 60;
	
	@Column(name = "lastUpdateOper")
	private String lastUpdateOper;
	
	@Column(name = "lastUpdateDate")
	private Date lastUpdateDate;
	
	@Column(name = "leaveSessionAgentOverTime")
	private Integer leaveSessionAgentOverTime;

}

排查

查看报错信息，发现打印出来的SQL有问题，update的部分属性值没有使用占位符?进行占位，而是变成了属性的名称

问题就出现在vdnId = vdnId，update时，属性值应该像后边的sessionExceptionOverTime 等属性一样，使用?进行占位的，这里却没有

sql 复制代码 
UPDATE t_mb_ccs_session_config SET vdnId = vdnId,sessionExceptionOverTime = ?,sessionExceptionAgentOverTime = ?,sessionExceptionOpenOverTime = ?,sessionNoStaffOverTime = ?,leaveSessionOverTime = ?,leaveAgentOverTime = ?,sessionQueueOverTime = ?,lastUpdateOper = ?,lastUpdateDate = ?,leaveSessionAgentOverTime = ? WHERE ( ( vdnId = ? ) )

原因

应该是mybatis框架3.5.9版本有与之前的版本有差异导致

解决

测试过程

为什么只有vdnId这个属性有异常，而其他属性却是正常的？

猜测：vdnId是主键，并且存在@Id注解

如果存在@Id注解的字段都不能参与update？那这个版本的mybatis框架还有使用的价值吗？

-- 测试一：执行其他业务的updateByExample方法

结果：updateByExample执行正常

经过前面的测试，update存在多个条件时，就算更新的字段包含了@Id注解的主键，SQL依旧是正常的

-- 测试二：为原本执行报错的update逻辑多加一个条件

结果：updateByExample执行正常

经过测试，发现在update条件只有主键ID的时候SQL才会出现错误

解决方案

-- 解决方法一：vdnId字段不参与update

结果：updateByExample执行正常

-- 解决方法二：既然想仅仅根据主键ID进行update，那么可以保留@Id主键，并且使用updateByPrimaryKey方法

结果：updateByExample执行正常

-- 解决方法三：主键ID字段去除@Id注解（不推荐！！！去掉@Id注解会影响到xxxByPrimaryKey等方法的使用）

结果：updateByExample执行正常
