MyBatis-plus使用lambda条件构造器报错问题及解决
使用lambda条件构造器报错
最近在学习mybatis-plus的使用,提高工作效率;在学习到使用lambda条件构造器查询时报错
我写的测试类如下:
@Test void selectLambda() { LambdaQueryWrapper<User> queryWrapper = new LambdaQueryWrapper<>(); queryWrapper.like(User :: getName, "W") .and(o -> o.lt(User :: getAge, 35)); List<User> users = userMapper.selectList(queryWrapper); System.out.println(users); }
测试方法运行,
提示如下错误
org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.builder.BuilderException: Error evaluating expression 'ew.sqlSegment != null and ew.sqlSegment != '' and ew.nonEmptyOfWhere'. Cause: org.apache.ibatis.ognl.OgnlException: sqlSegment [java.lang.ExceptionInInitializerError]

看到这种错误我一脸懵逼
代码都是照着官网和推荐的学习视频敲得,lambda的语法用的也是最简单的,应该没有语法错误,但就是无法执行成功;
我使用的mybatis-plus的版本号为:3.4.3.2,是现在最新的版本
项目依赖如下:
在网上找了好久的解决方案,基本上都是让我把mybatis-plus的版本回退到3.1.0,我也试了一下,确实可以,但是我觉得3.1.0的版本还是太旧了,于是继续baidu,希望能继续找到解决方案。
最后我在mybatis-plus的更新日志里发现一条:
更新日志里说3.4.4.2的版本解决了lambda在JDK16中无法运行的问题,而我因为是自学项目,正好JDK用的就是JDK16,于是我试着把项目的JDK改为1.8,然后试着运行一下,居然可以了 o(╥﹏╥)o,WC浪费了我好多时间。。。。。
执行成功截图:
实在是太坑了
因此记录一下;看来官方的更新文档与事实不符啊o(╥﹏╥)o
不过现在企业项目中应该还没有用到JDK16的,基本上都是1.8或者11
所以大家还是可以放心在项目中加上新版的mybatis-plus使用
用起来还是蛮香的,O(∩_∩)O哈哈~
总结
以上为个人经验,希望能给大家一个参考,也希望大家多多支持脚本之家。
- 使用mybatis-plus报错Invalid bound statement (not found)错误
