@Transactional(rollbackFor = Exception.class)public boolean deletexxxIds(List<String> ids) {return ids != null && ! ids.isEmpty() ? this.remove(this.lambdaQuery().in(xxx::getId, ids)) : false;}问题在于：
-
lambdaQuery()创建的是一个LambdaQueryWrapper，而remove()方法内部会尝试获取sqlSegment -
在某些 MyBatis-Plus 版本中，这种链式调用会导致
getSqlSegment方法被错误调用
解决方案
方案1：改用传统 QueryWrapper（推荐）
@Override
@Transactional(rollbackFor = Exception.class)
public boolean deletexxxIds(List<String> ids) {if (ids == null || ids.isEmpty()) {return false;}QueryWrapper<xxx> wrapper = new QueryWrapper<>();wrapper.in("id", ids);return this.remove(wrapper);
}方案2：分离 Lambda 表达式构造
@Override
@Transactional(rollbackFor = Exception.class)
public boolean deletexxxIds(List<String> ids) {if (ids == null || ids.isEmpty()) {return false;}LambdaQueryWrapper<xxx> wrapper = Wrappers.lambdaQuery();wrapper.in(xxx::getId, ids);return this.remove(wrapper);
}方案4：升级 MyBatis-Plus 版本
如果是版本问题（特别是 3.4.x 之前的版本），建议升级到最新稳定版：
<dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-boot-starter</artifactId><version>3.5.3.1</version>
</dependency>为什么这样修改有效？
原始代码中的链式调用 this.remove(this.lambdaQuery().in(...)) 在某些版本中会导致：
-
条件构造器被过早评估
-
内部尝试获取
sqlSegment时上下文不完整
而分离构造步骤（方案2）或使用传统 QueryWrapper（方案1）可以避免这种内部处理冲突。这是 MyBatis-Plus 实现细节导致的问题，官方文档中也推荐避免过于复杂的链式调用。
