SSM框架搭建之在classes中找不到spring等配置文件

今天算是什么也没干，熟悉了搭建SSM框架，之前一直没有自己搭建过，所以导致博主踩了很多坑，纪念一下。不说废话了，进入正题吧。

当你搜到这篇博客时，就代表你已经知道了SSM是什么，它们整合的思路是什么，这些我就不说了，直接开始。以下是博主亲测，不会有问题，除非你那里搭错了

最终项目结构

咱们来说说今天遇到的坑好吧

1. 使用maven搭建ssm框架遇到的spring找不到配置文件问题

在打包部署时，为了防止mybatis的mapper文件被过滤掉，在pom文件的build节点下加入了如下代码：

<resources>
    <resource>
        <directory>src/main/java</directory>
        <includes>
            <include>**/*.properties</include>
            <include>**/*.xml</include>
        </includes>
        <filtering>false</filtering>
    </resource>
</resources>

然后发布后就悲剧了，提示applicationContext-*文件找不到，报了FileNotFindExeception

Could not resolve bean definition resource pattern [classpath:spring/applicationContext-*…

原因：

maven默认扫描src/main/resources中的xml文件而不理会src/main/java中的xml文件，所以我们添加了resource节点，这样就会改变maven默认的扫描策略，造成src/main/resources下的配置文件打包丢失

解决方法：

再添加一个resource节点

<!-- 如果不添加此节点mybatis的mapper.xml文件都会被漏掉。 -->
      <resources>
          <resource>
              <directory>src/main/java</directory>
              <includes>
                  <include>**/*.properties</include>
                  <include>**/*.xml</include>
              </includes>
              <filtering>false</filtering>
          </resource>
          <!-- 如果不添加此节点spring的.xml文件都会被漏掉。 -->
          <resource>
              <directory>src/main/resources</directory>
              <includes>
                  <include>**/*.properties</include>
                  <include>**/*.xml</include>
              </includes>
              <filtering>false</filtering>
          </resource>
      </resources>

2. 使用maven的tomcat插件

使用了maven的tomcat插件启动项目后，就不能访问tomcat的主页了，我还傻呵呵的去访问，以为自己哪里写错了！！！
