如果你觉得本教程或者项目源码对你有用,请支持下,或者点击网页下方打赏按钮,谢谢

    首先说说 IDEA 12,由于myeclipse越来越卡,我改用idea12 了,发现其功能强悍到eclipse无法比拟,此款ide理解上下文是一等一的,不用什么jquery插件,extjs插件,都可以实现全智能的代码提示。速度什么的都比myeclipse快。而且IDEA提供了android支持struts spring hibernate 支持。下面,我讲教大家完成一个基于全注解的Spirng3.2+hibernate4+struts2.3 登录项目,本人对Java极其热爱,爱好Java编程的朋友可以加QQ群:185441009

第一步 创建工程:

图中的project name 就是eclipse里的workspace,下面有个额module name,这个module 才是真正的项目,如果你不改名字,它会自动创建一个跟project name一样的工程。

点 next

选择相应的框架,包括application server tomcat,这里要说明的是,选择的时候它会提示是否下载所依赖的jar

 

记住要选中上图中Level为为global 意思就是这个lib是Userlibary,同理,spring hibernate 亦是如此。

完了之后 finish,项目就创建完毕了。

第二步,配置lib

ide下载的jar并不是完美的,有些冲突,有些少包多包。项目上右键,选择打开project Structure 选择global library,这里可以配置lib。

经过修整,最终导入的包如下。

 

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> //这是注解加载action类的时候用的
            <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 配置数据源

点击ide右边的database

然后右击 add 按照步骤一步一步添加数据源 完成之后如图所示

 

之后选中IDE侧面的 persistence 选中hibernate.cfg.xml 右击

 

 

 

选择 genernate mapping,按照步骤生成带注解的pojo类。

创建相应的配置文件 和 java 类 工程结构如图所示 struts无需配置。

 

 

 

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">

        <property name="hibernate.c3p0.timeout">1800</property>
        <property name="hibernate.c3p0.max_statements">50</property>
        <mapping class="com.blog.entity.AppInitEntity"/>
        <mapping class="com.blog.entity.ArticleEntity"/>
        <mapping class="com.blog.entity.CommentEntity"/>
        <mapping class="com.blog.entity.UserEntity"/>
        <!-- DB schema will be updated if needed -->
        <!-- <property name="hbm2ddl.auto">update</property> -->
    </session-factory>
</hibernate-configuration>

 

spring 配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

配置完毕后,点击上面的tomcat毛旁边的运行按钮。说是登陆,其实我只查询了对象。数据库是mysql,自己创建吧。user表里面有个id字段。道理是一样的。

还有什么问题加我QQ.
