ssm配置信息总结,第1张

ssm配置信息 创建ssm web项目
  1. 新建一个普通的maven项目
  2. 在pom文件中添加war，引入依赖
  3. 添加web模块
    • 在main目录中新建一个目录webapp，注意是否是web目录
    • 在Project Structur中的Moudles里面对应项目的web中Deployment Descriptors中点击+号新建一个web.xml文件，选择的路径是\src\main\webapp\WEB-INF\web.xml
创建java web servlet项目
  1. 新建一个project，新建一个空工程，然后在空工程下新建module，
  2. 新建模块
    • 这里新建的是一个普通的java se模块，
  3. 让module变成javaEE模块，让Moudle变成webapp的模块，符合webapp规范，
    • 在Module上右击：选择Add Framework Support （添加框架支持）
    • 选择web application （添加web框架的支持）
    • IDEA会自动生成一个符合servlet规范的webapp目录结构
  4. 添加jar包支持
    • 将tomcat里面CATALINA_HOME\lib\servlet-api.jar和jsp-api.jar添加到classpath中
    • 这里的IDEA指的是IDEA的classpath
    • project Structure中选择modules在Dependencies中点击+号选择添加jar
一个配置文件整合 spring mvc
