這幾天在學習java web中的SSh架構,開始搭建時候遇到不少問題,通過幾天的探索,記錄一下SSH 的搭建

一.使用Idea建立新項目java

1.選擇Spring相關

2.struts2相關

3.hibernate相關

4.選擇完成後next->finish

二.在項目web/WEB-INF目錄下建立lib 和classe文件夾將相關的jar包導入項目
三.依賴jar包web

四調整項目依賴路徑
spring

選擇放jar包的lib文件夾apache

點擊OKtomcat

而後apply->ok
四.配置tomcat架構

五.測試修改app

報錯1.運行項目報錯,錯誤以下

21-Aug-2018 14:26:38.160 警告 [RMI TCP Connection(3)-127.0.0.1] org.apache.tomcat.util.descriptor.web.WebXml.setVersion Unknown version string [4.0]. Default version will be used.

這個錯誤是由於web.xml中的structs2 配置錯誤

修改配置爲:

<filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

這裏是須要添加一個xwork-coreXXX.jar的包而後在web.xml中配置 <listener>,配置以下ssh

<listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring-config.xml</param-value>
    </context-param>

啓動項目,啓動成功,完成ssh的基本配置tcp
