3.1.0以及3.1.1版本 LambdaQueryWrapper 运行出错提示：ew.sqlSegment != null and ew.sqlSegment != '' and ew.nonEmptyOfWhere' This is impossible to happen #1187

Closed MichaelXcy closed 5 years ago

MichaelXcy commented 5 years ago

当前使用版本(必须填写清楚，否则不予处理)

3.1.0

该问题是怎么引起的？*([最新版](https://search.maven.org/search?q=g:com.baomidou%20a:mybatis-)上已修复的会直接close掉)**

LambdaQueryWrapper wrapper = new QueryWrapper().lambda(); wrapper.eq(MpSmsBlackList::getPhoneNo, phoneNo);

这么写查询的话，这个条件构造器还没有传到select里面，就报错了，提示： nested exception is 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 [com.baomidou.mybatisplus.core.exceptions.MybatisPlusException: This is impossible to happen

重现步骤

1、定义条件构造器： LambdaQueryWrapper wrapper = new QueryWrapper().lambda(); wrapper.eq(MpSmsBlackList::getPhoneNo, phoneNo);

2、打包环境是jdk1.8.0_191、运行环境是Linux 的jdk1.8.0_12

3、启动程序，访问接口，执行到这个条件构造器的时候就报错

@Param("ew")

MichaelXcy commented 5 years ago

@param("ew")

大神，这个是啥意思？加在哪里呢？

miemieYaho commented 5 years ago

放你自己写的 method 的入参 wrapper 前面

MichaelXcy commented 5 years ago

method 的入参 wrapper 前面

我调用的是继承自B阿瑟

放你自己写的 method 的入参 wrapper 前面

我调用的是继承自IService的方法，不是自己写的方法。IService里面为啥没有这个注解的呀 我更换了3.1.1, 3.1.0，3.0.7.1 三个版本都是同样的错误。

那就是没用对,去看 samples

MichaelXcy commented 5 years ago

那就是没用对,去看 samples

哦，为啥 mybatis-plus-extension.jar 这个包里面的顶级IService接口里面的方法，wrapper前面都没有加这个@param("ew") 注解的呢？我看了IService所有的方法都没加，难道是我引用的包有问题？

miemieYaho commented 5 years ago

这是 mapper 里的

MichaelXcy commented 5 years ago

这是 mapper 里的

哦哦，但是奇怪的是，这个代码，直接在IDEA启动本地跑的时候是正常的，打包部署到linux环境就不行。

MichaelXcy commented 5 years ago

那就是没用对,去看 samples

官网的sample没看到有使用 LambdaQueryWrapper 的呀，您可以指点一下或者哪里有这个使用的例子么？现在项目急用，碰到这个问题搞不定了，多谢大侠

本地可以就检查 jar 包的依赖有没有冲突,检查依赖的 jar 是否一致

MichaelXcy commented 5 years ago

本地可以就检查 jar 包的依赖有没有冲突,检查依赖的 jar 是否一致

检查了没有冲突的。我的使用方法是：


1、MpSmsValidateInfoServiceImpl 这个业务服务类继承ServiceImpl如下：

public class MpSmsValidateInfoServiceImpl extends ServiceImpl<IMpSmsValidateInfoMapper, MpSmsValidateInfo> implements IMpSmsValidateInfoService {
.....
}

2、public interface IMpSmsValidateInfoMapper extends BaseMapper<MpSmsValidateInfo>

3、public interface IMpSmsValidateInfoService extends IService<MpSmsValidateInfo> 

4、在业务服务实现类中使用：
 LambdaQueryWrapper<MpSmsBlackList> wrapper = new QueryWrapper<MpSmsBlackList>().lambda();
        wrapper.eq(MpSmsBlackList::getPhoneNo,  phoneNo);

就在代码执行到Service里面带 :: 这个Lambda表达式时就出错了。

只要是maven打包之后启动访问就出错，IDEA里面启动访问就没错。

把你调用的代码贴全一点啊，还有错误日志也贴全一点啊

把你调用的代码贴全一点啊，还有错误日志也贴全一点啊

代码调用处：

`@Service @Slf4j @Transactional public class MpSmsValidateInfoServiceImpl extends ServiceImpl<IMpSmsValidateInfoMapper, MpSmsValidateInfo> implements IMpSmsValidateInfoService {

@Override
public String getVerificationCode(String phoneNo, String openId) throws ServiceException {

    log.error("进入SMSValidate-0");

    // 1.号码是否在黑名单
    LambdaQueryWrapper<MpSmsBlackList> wrapper = new QueryWrapper<MpSmsBlackList>().lambda();
    wrapper.eq(MpSmsBlackList::getPhoneNo,  phoneNo);  // 执行到这一行就出错了，出错日志如下

自行检查服务器 jdk 版本,只支持 openJDK 和 oracleJDK 8+

我的是springboot的微服务项目，现在本地打包后，直接本地启动这个微服务的jar包，访问也是一样的出错，但是这个微服务直接在IDEA里面启动访问就完全正常，我本机只有一个jdk，版本是 1.8.0_191，IDEA里面配置的也是引用了我本地安装的这个jdk版本的。

MichaelXcy commented 5 years ago

@miemieYaho @yuxiaobin

打扰了，多谢两位，现在可以了，打包的问题。springboot打包时不指定jdk版本用的就是他默认的，不是1.8.

MybatisPlus 很好很强大，棒棒哒~ 用了好几年了，加油
