Struts2+Spring+Hibernate三大框架的配置

本文主要是为了方便自己的在工作中的查看需求，如果有什么疑惑可以在留言中交流。

hibernate的实体映射文件：
首先建立一个类User.java类，并有以下属性。此处省略getter和setter方法。

public class User implements Serializable {

    private int id;             //id
    private String name;        //用户名
    private String account;     //账户
    private String psw;         //密码
    private String college;     //所属学院
    private int isManager;      //是否是排课老师
    private int isRoot;         //是否是管理员
    private String email;       //Email邮箱

    public User()
    {

    }

    public User(String name, String account, String psw, int isManager, int isRoot, String email) {
        super();
        this.name = name;
        this.account = account;
        this.psw = psw;
        this.isManager = isManager;
        this.isRoot = isRoot;
        this.email = email;
    }
    ......
}

User.hbm.xml 映射文件如下所示：

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

<hibernate-mapping package="com.etcss.domain">

    <class name="User" table="users">
        <id name="id" >
            <generator class="native"/>
        </id>
        <property name="name" not-null="false" type="string"/>
        <property name="account" not-null="false" type="string"/>
        <property name="psw" not-null="false" type="string"/>
        <property name="college" not-null="false" type="string"/>
        <property name="email" not-null="false" type="string"/>
        <property name="isManager" not-null="false" type="integer"/>
        <property name="isRoot" not-null="false" type="integer"/>
    </class>

</hibernate-mapping>

配置structs2 相关的配置文件struts.xml：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
    <!-- 指定Web应用的默认编码集,相当于调用HttpServletRequest的setCharacterEncoding方法 -->
    <constant name="struts.i18n.encoding" value="UTF-8"/>
    <!-- 该属性指定需要Struts 2处理的请求后缀，该属性的默认值是action，即所有匹配*.action的请求都由Struts2处理。 如果用户需要指定多个请求后缀，则多个后缀之间以英文逗号（,）隔开。 -->
    <constant name="struts.action.extension" value="do,action"/>
    <!-- 设置浏览器是否缓存静态内容,默认值为true(生产环境下使用),开发阶段最好关闭 -->
    <constant name="struts.serve.static.browserCache" value="true"/>
    <!-- 当struts的配置文件修改后,系统是否自动重新加载该文件,默认值为false(生产环境下使用),开发阶段最好打开 -->
    <constant name="struts.configuration.xml.reload" value="true"/>
    <!-- 开发模式下使用,这样可以打印出更详细的错误信息 -->
    <constant name="struts.devMode" value="false" />
     <!-- 默认的视图主题 -->
    <constant name="struts.ui.theme" value="simple" />
    <constant name="struts.objectFactory" value="spring" />
   <!-- <package name="index" namespace="/index" extends="struts-default"> <global-results> <result name="message">/index.jsp</result> </global-results> <action name="*" class="loginManageController" method="{1}"> <result name="jsjlab">/WEB-INF/page/jsjlab.jsp</result> <result name="jsjplab">/WEB-INF/page/jsjplab.jsp</result> <result name="xxgclab">/WEB-INF/page/xxgclab.jsp</result> </action> </package> -->

    <include file="./struts-login.xml"></include>
    <include file="./struts-user.xml"></include>
    <include file="./struts-labRoomCourse.xml"></include>
    <include file="./struts-root.xml"></include>   
    <include file="./struts-labBuilding.xml"></include>
    <include file="./struts-subject.xml"></include>
    <include file="./struts-room.xml"></include>
    <include file="./struts-course.xml"></include>
    <include file="./struts-tools.xml"></include>

    <!-- this is a test -->
    <package name="test" namespace="/" extends="struts-default">
        <global-results>
            <result name="message">/index.jsp</result>
        </global-results>
        <action name="*" class="myTestController" method="{1}">
            <result name="pagelist">/WEB-INF/page/test/pagelist.jsp</result>
        </action>
    </package>
</struts>

如上所示struts的配置文件可以分开文件来写，用include标签引入即可。
