基於IDEA 最新Spirng3.2+hibernate4+struts2.3 全註解配置 登...

若是你以爲本教程或者項目源碼對你有用，請支持下，或者點擊網頁下方打賞按鈕，謝謝

    首先說說 IDEA 12，因爲myeclipse愈來愈卡，我改用idea12 了，發現其功能強悍到eclipse沒法比擬，此款ide理解上下文是一等一的，不用什麼jquery插件，extjs插件，均可以實現全智能的代碼提示。速度什麼的都比myeclipse快。並且IDEA提供了android支持struts spring hibernate 支持。下面，我講教你們完成一個基於全註解的Spirng3.2+hibernate4+struts2.3 登陸項目，本人對Java極其熱愛，愛好Java編程的朋友能夠加QQ羣:185441009

第一步 建立工程：

圖中的project name 就是eclipse裏的workspace，下面有個額module name，這個module 纔是真正的項目，若是你不更名字，它會自動建立一個跟project name同樣的工程。

點 next

選擇相應的框架，包括application server tomcat，這裏要說明的是，選擇的時候它會提示是否下載所依賴的jar

 

記住要選中上圖中Level爲爲global 意思就是這個lib是Userlibary,同理，spring hibernate 亦是如此。

完了以後 finish，項目就建立完畢了。

第二步，配置lib

ide下載的jar並非完美的，有些衝突，有些少包多包。項目上右鍵，選擇打開project Structure 選擇global library，這裏能夠配置lib。

通過修整，最終導入的包以下。

 

第三步 搭建ssh框架

web.xml 

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
         version="2.5">

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
        <init-param>
            <param-name>struts.ui.theme</param-name>
            <param-value>simple</param-value>
        </init-param>
        <init-param>
            <param-name>struts.objectFactory</param-name>
            <param-value>spring</param-value>
        </init-param>
        <init-param>
            <param-name>struts.convention.action.packages</param-name> //這是註解加載action類的時候用的
            <param-value>com.blog.actions</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

</web-app>

 

第二步 配置數據源

點擊ide右邊的database

而後右擊 add 按照步驟一步一步添加數據源 完成以後如圖所示

 

以後選中IDE側面的 persistence 選中hibernate.cfg.xml 右擊

 

 

 

選擇 genernate mapping,按照步驟生成帶註解的pojo類。

建立相應的配置文件 和 java 類 工程結構如圖所示 struts無需配置。

 

 

 

hibernate 配置文件：

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD//EN"
        " http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

        <!-- DB schema will be updated if needed -->
        <!-- <property name="hbm2ddl.auto">update</property> -->
    </session-factory>
</hibernate-configuration>

配置完畢後，點擊上面的tomcat毛旁邊的運行按鈕。說是登錄，其實我只查詢了對象。數據庫是mysql，本身建立吧。user表裏面有個id字段。道理是同樣的。

還有什麼問題加我QQ.
