整合ssm框架的时候出现错误org.apache.catalina.LifecycleException: 无法启动组件[StandardEngine[Catalina].StandardHost[l

启动tomcat后报出错误如下：总的就是（

打开Project Structure后看到的是，发现和之前的不太一样，servlet-api的jar包在外面，可能是导入错误，

本地仓库打开后发现有两个servlet-api，一个是javax.servlet-api版本是3.1，还有一个是servlet-api版本是2.5和2.4，重新导入依赖，然后加入lib下后

然后刚才的错误好了，相继出现了以下错误，第一眼就想起来是xml文件中没有修改正确，idea会自动导入cache，但是导入的是错误的，我只改了后面，没有改前面

修改之后重新reload就启动了浏览器

点击进入书籍页面后出现错误

开始排查错误
问题:bean不存在
步骤:
1．查看这个bean注入是否成功!ok
2. Junit单元测试，看我们的代码是否能够查询出来结果!ok
3．问题，一定不在我们的底层，spring出问题了
4.SpringMVC，整合的时候没调用到我们的service层的bean;

• applicationcontext.xml没有注入bean
• web.xml中，我们也绑定过配置文件!，发现问题，我们配置的是spring-mvc.xml
  这里面确实没有service bean，所以报空指针
  
  
  
  只改applicationContext.xml就可以了

步骤2测试的时候显示找不到哪些测试的方法，没有绑定，这里重要的事情说三遍！！！加资源过滤，加资源过滤，加资源过滤
