构造函数抛出异常；嵌套异常为java.lang.IllegalArgumentException：找不到域类的查询类

标签： java spring maven spring-boot querydsl

我在sts中创建了一个maven项目，并且试图为该项目创建一个war文件。我也为我的班级配置了querydsl。当我运行maven install时，一类给我一个错误响应。错误：在文件[C：\ Users \ vince \ Documents \ workspace-spring-tool-suite-4-4.0.1.RELEASE \ project \ target \ test-classes \ com \ project中定义的名称为'productBrandController'的bean创建时出错\ project \ StoreBased \ ProductBrandController.class]：通过构造函数参数0表示的不满意依赖项；嵌套的异常是org.springframework.beans.factory.BeanCreationException：创建名称为'productBrandRepository'的bean时出错：调用init方法失败；嵌套异常是org.springframework.beans.BeanInstantiationException：无法实例化[org.springframework.data.mongodb.repository.support.QuerydslMongoPredicateExecutor]：构造函数引发了异常；嵌套的异常是java.lang.IllegalArgumentException：找不到域类project.StoreBased.ProductBrand的查询类project.QProductBrand！我需要有关我的pom文件的帮助（不确定javax.xml.bind是否可能是罪魁祸首），也不确定我的输出目录是否正确（我已经尝试使用java代替输出注释）。非常感谢您的帮助！

此问题的原因： 

Your Query Classes are generated in different package (i.e. inside /annotations) and 
you are trying to find it from different package.

解决方案：

更改outputDirectory路径（即用于生成'Q'前缀类的标签位置）

<outputDirectory>target/generated-sources/annotations</outputDirectory>

到

<outputDirectory>target/generated-sources/apt</outputDirectory>

删除目标文件夹并执行

  

mvn全新安装
