  • 基于maven的ssh框架一步一步搭建（一）

    一、新建maven项目，配置ssh框架pom的最低支持

    1、新建一个maven项目 

    2、添加一个web.xml

    3、基本ssh框架pom.xml配置

    二、maven webproject 整合struts2

    1、web.xml 加入中心拦截器配置

        <filter-mapping>
            <filter-name>struts2</filter-name>
            <url-pattern>/*</url-pattern>
        </filter-mapping>

    2、加入log4j.xml

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE log4j:configuration PUBLIC "-//Apache//DTD Log4j 1.2//EN"
                                        "http://logging.apache.org/log4j/docs/api/org/apache/log4j/xml/log4j.dtd">

            <appender-ref ref="RootConsoleAppender" />
        </root>
     
    </log4j:configuration>

    3、引入struts2.xml 根据约定由于配置原则，将此配置文件放在更目录即可

    6
    7
    8
    9
    10
    11
    12
    13
    <?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>
        <package name="fengshu" namespace="/user" extends="struts-default">
     
            <!--<action name="user"
                class="com.fengshu.limanman.winssage.controller.LoginController">
                <result name="success">/pages/index.jsp</result>
            </action>-->
        </package>
    </struts>

    4、建一个测试jsp在webapp/pages/index.jsp

    ?

    3
    4
    5
    6
    7
    8
    9
    10
    11
    <%@ page language="java" contentType="text/html; charset=utf-8"
        pageEncoding="utf-8"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <title>Insert title here</title>
    </head>
    <body>hello limanman
    </body>
    </html>

    5、写一个controller

    ?
    1
    2
    3
    4
    5
    6
    7
    8
    9
    10
    11
    12
    13
    14
    15
    16
    17
    package com.fengshu.limanman.controller;
     
    import org.apache.log4j.Logger;
     
    import com.opensymphony.xwork2.ActionSupport;
     
    public class LoginController extends ActionSupport {
        private static final long serialVersionUID = 1L;
        private Logger log=Logger.getLogger(this.getClass());
         
        public String  login() {
            log.info("hello  i am limanman");
            return "succerss";
             
        }
     
    }

    6、配置struts2.xml

    ?
    1
    2
    3
    4
    5
    6
    7
    8
    9
    10
    11
    12
    <?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>
        <package name="fengshu" namespace="/" extends="struts-default">
     
            <action name="user" class="com.fengshu.limanman.controller.LoginController">
                <result name="success">/pages/index.jsp</result>
            </action>
        </package>
    </struts>

    7、暂时注释掉pom.xml中的struts2-spring-plugin

    因为还没有整合spring，如果加入struts2-spring-plugin将会报空指针异常，整合spring后需要加入此jar包，下面将不再提及。


     

    8、配置jetty运行环境，开发的时候我们一般使用jetty服务器，而不用tomcat

    在pom.xml中加入jetty插件，并且配置根目录目录

    9、第一个里程碑,第一次运行项目

    （1）jetty:run -Djetty.port=9080 -Dmaven.test.skip=true 跑起项目

    (2)效果截图

    三、将spring 整合进来

    1、web.xml加入spring监听

        </context-param>
        <!-- Spring Listener -->
        <listener>
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>

    2、将strut2交给spring管理

    （1）修改strut2.xml

        "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
        "http://struts.apache.org/dtds/struts-2.0.dtd">
    <struts>
        <package name="fengshu" namespace="/" extends="struts-default">
     
            <action name="user" class="loginController">
                <result name="success">/pages/index.jsp</result>
            </action>
        </package>
    </struts>

    （2）添加spring配置文件

    ?
    1
    2
     <bean id="loginController" class="com.fengshu.limanman.controller.LoginController">
        </bean>

    (3)运行 it is aok!

    四、spring再整合hibernate 

    1、加入datasource

    ?
    1
    2
    3
    4
    5
    6
    7
    8
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
            <property name="driverClassName" value="com.mysql.jdbc.Driver">
            </property>
            <property name="url" value="jdbc:mysql://localhost:3306/ddd">
            </property>
            <property name="username" value="root"></property>
            <property name="password" value="root"></property>
        </bean>

    2、加入sessionFactory

    ?
    1
    2
    3
    4
    5
    6
    7
    8
    9
    10
    11
    12
    13
    14
    15
    16
    17
    18
    19
    20
    <bean id="sessionFactory"
            class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
            <property name="dataSource">
                <ref bean="dataSource" />
            </property>
            <property name="annotatedClasses">
                <list>
                    <value>com.winssage.bslogic.core.User</value>
                </list>
            </property>
            <property name="hibernateProperties">
                <props>
                    <prop key="hibernate.dialect">
                        org.hibernate.dialect.Mysql5Dialect
                    </prop>
                    <prop key="hibernate.show_sql">true</prop>
                    <prop key="hibernate.hbm2ddl.auto">update</prop>
                </props>
            </property>
        </bean>

    3、运行项目后报错 

    经检查发现是因为没有mysql驱动，也没有hibernate-anation 包

    给改hibernate pom.xml 配置

    ?

    5
    6
    7
    8
    9
    10
    11
    12
    13
    14
    15
    16
    17
    18
    19
    20
    21
    22
    23
    24
    25
    26
    27
    28
    29
    30
    31
    32
    <!-- 添加Hibernate依赖 -->

    4、再次启动 

    已自动更新了表，注意应该讲hibernate.hbm2ddl.auto设置为create才能自动创建表

    到此hibernate已经成功添加进来
