SSM框架搭建

新建一个maven工程

NEXT，选择webapp

NEXT，然后finsh

建立完后的框架目录结构为(可以忽略掉jsp页面带来的影响，删掉重新创建一个就好)

未出现src/main/java目录，可能是因为用了maven工程默认的jre，就要在build path 里面先移除掉默认的JRE，再添加工作空间默认的jdk

这时你会看到工程出现ERROR，这是因为web.xml和pom.xml文件还没有完善好，以下的web.xml中加入了Shiro过滤器用于登录还有授权功能方面的

进行完上面的步骤之后将工程Maven->Update project，maven会自动将pom.xml里面的jar包自动下载下来，

下载的完成后假如出现以下图片上的问题，也不要慌，小姐姐也是这样一步步走过来的

打开工程所在目录，找到settings文件夹，打开org.eclipse.wst.common.project.facet.core.xml，替换以下内容，然后再Update project就OK了

<?xml version="1.0" encoding="UTF-8"?><faceted-project>  <fixed facet="wst.jsdt.web"/>  <installed facet="java" version="1.7"/>  <installed facet="jst.web" version="3.0"/>  <installed facet="wst.jsdt.web" version="1.0"/></faceted-project>

接下来就直接上其他的配置

applicationContext.xml

applicationContext-shiro.xml（没有在web.xml里面加shiroFilter的就不用加此配置文件，有关shiro的都可以忽略，并且去掉web有关shiro的）

启动项目，在浏览器里输入http://localhost:8080/ssm/login，
WEB-INF/views/index.jsp ，WEB-INF目录下的index.jsp

好了、到这里一个简单的SSM就搭建好了~
