500错误，找不到spring.xml

已在问答区查找了相似问题的解决方案，但并没有效果，已经不知道怎么解决了。

已在myWeb模块配置myService模块的依赖

同学你好，关于sm_web和sm_service模块关联的问题，是在sm_web模块的pom文件中引入sm_service的依赖即可。

同学的项目时没有关联上，建议同学查看一下sm_service模块的target模块下是否有spring.xml文件，如：

如果没有，建议同学复制一份spring.xml文件到target目录下。

祝：学习愉快~

已经在web中配置service的依赖了；但似乎并没有什么作用；

我现在自己折腾了一个可行的备用方案：

分为3个步骤，步骤2和3解决的是xml找不到问题，步骤1解决的是bean名称不存在的问题；

现在的问题是myService和myWeb的spring.xml相互独立，业务层如何和表示层关联起来？因为我配置了service依赖并没有起到任何作用。

步骤1

将spring.xml拷贝到myWeb模块中的resources文件夹，仅配置myWeb模块的全局扫描；

<!--全局自动扫描-->
<context:component-scan base-package="com.mike.myWeb"/>
<aop:aspectj-autoproxy/>

步骤2

新建class文件夹，路径为：myWeb-->src-->webapp-->WEB-INF-->classes；

步骤3

配置编译输出路径至classes文件夹

在sm_web里面引入依赖会报错啊

问一下同学报什么错，建议同学将报错截图贴一下。另外建议同学新开一个问题提问。祝：学习愉快~

找不到spring配置文件的情况，一般是路径和文件名的问题。我看了你的文件是存在并且是放在myService模型中的，那么问题应该出在myWeb和myService关联的问题了。建议仔细检查pom.xml中的关联。可以另提问截图方便查看
