基于maven的ssh框架一步一步搭建

引用 http://www.open-open.com/lib/view/open1405494785437.html

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

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

• 3、基本ssh框架pom.xml配置

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">  <modelVersion>4.0.0</modelVersion>  <groupId>com.winssage.fengshu</groupId>  <artifactId>winssage</artifactId>  <version>0.0.1-SNAPSHOT</version>  <packaging>war</packaging>  <name>winssage</name>  <url>http://maven.apache.org</url>  <properties>    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>  </properties>  <dependencies>    <dependency>      <groupId>junit</groupId>      <artifactId>junit</artifactId>      <version>4.10</version>      <scope>test</scope>    </dependency>     <!-- 添加SSH依赖 -->     <!-- Struts2 -->     <dependency>         <groupId>org.apache.struts</groupId>         <artifactId>struts2-core</artifactId>         <version>2.3.1</version>     </dependency>     <dependency>         <groupId>org.apache.struts</groupId>         <artifactId>struts2-spring-plugin</artifactId>         <version>2.3.1</version>     </dependency>      <!-- 添加Hibernate依赖 -->     <dependency>         <groupId>org.hibernate</groupId>         <artifactId>hibernate-core</artifactId>         <version>3.6.5.Final</version>     </dependency>     <dependency>         <groupId>commons-dbcp</groupId>         <artifactId>commons-dbcp</artifactId>         <version>1.4</version>     </dependency>     <!-- 添加Log4J依赖 -->     <dependency>         <groupId>log4j</groupId>         <artifactId>log4j</artifactId>         <version>1.2.16</version>     </dependency>     <dependency>       <groupId>org.slf4j</groupId>       <artifactId>slf4j-api</artifactId>       <version>1.6.1</version>     </dependency>     <dependency>         <groupId>org.slf4j</groupId>         <artifactId>slf4j-nop</artifactId>         <version>1.6.4</version>     </dependency>     <!-- 添加javassist -->     <dependency>         <groupId>javassist</groupId>         <artifactId>javassist</artifactId>         <version>3.11.0.GA</version>     </dependency>     <!-- 添加Spring依赖 -->     <dependency>         <groupId>org.springframework</groupId>         <artifactId>spring-core</artifactId>         <version>3.1.1.RELEASE</version>     </dependency>     <dependency>         <groupId>org.springframework</groupId>         <artifactId>spring-beans</artifactId>         <version>3.1.1.RELEASE</version>     </dependency>     <dependency>         <groupId>org.springframework</groupId>         <artifactId>spring-context</artifactId>         <version>3.1.1.RELEASE</version>     </dependency>     <dependency>         <groupId>org.springframework</groupId>         <artifactId>spring-jdbc</artifactId>         <version>3.1.1.RELEASE</version>     </dependency>     <dependency>         <groupId>org.springframework</groupId>         <artifactId>spring-orm</artifactId>         <version>3.1.1.RELEASE</version>     </dependency>     <dependency>         <groupId>org.springframework</groupId>         <artifactId>spring-web</artifactId>         <version>3.1.1.RELEASE</version>     </dependency>   </dependencies></project>

二、maven webproject 整合struts2

• 1、web.xml 加入中心拦截器配置

<filter>        <filter-name>struts2</filter-name>        <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>    </filter>    <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"><log4j:configuration>    <appender class="org.apache.log4j.ConsoleAppender" name="RootConsoleAppender">        <param name="Threshold" value="debug" />        <layout class="org.apache.log4j.PatternLayout">            <param name="ConversionPattern" value="%d{ABSOLUTE} %-5p [%c{1}] %m%n" />        </layout>    </appender>    <category name="com.fengshu.limanman.winssage">        <priority value="debug" />    </category>    <category name="org.springframework">        <priority value="warn" />    </category>    <category name="org.hibernate">        <priority value="warn" />    </category>    <category name="org.dbunit">        <priority value="warn" />    </category>    <category name="com.mchange.v2">        <priority value="warn" />    </category>    <category name="org.apache">        <priority value="warn" />    </category>    <category name="org.logicalcobwebs">        <priority value="warn" />    </category>    <category name="com.opensymphony">        <priority value="warn" />    </category>    <root>        <level value="info" />        <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

<?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

<%@ 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

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

<?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

<build>        <plugins>            <!-- 配置加入jetty服务器，开发时我们一般使用jetty服务器 -->            <plugin>                <groupId>org.mortbay.jetty</groupId>                <artifactId>jetty-maven-plugin</artifactId>                <configuration>                    <!-- 设置扫描target/classes内部文件变化时间间隔 -->                    <scanIntervalSeconds>2</scanIntervalSeconds>                    <webApp>                        <contextPath>/limanman</contextPath>                    </webApp>                </configuration>            </plugin>            <!-- compiler插件, 设定JDK版本 -->            <plugin>                <groupId>org.apache.maven.plugins</groupId>                <artifactId>maven-compiler-plugin</artifactId>                <version>3.0</version>                <configuration>                    <source>1.6</source>                    <target>1.6</target>                    <showWarnings>true</showWarnings>                </configuration>            </plugin>            <!-- war打包插件, 设定war包名称不带版本号 -->            <plugin>                <groupId>org.apache.maven.plugins</groupId>                <artifactId>maven-war-plugin</artifactId>                <version>2.3</version>                <configuration>                    <warName>winssage</warName>                </configuration>            </plugin>            <!-- eclipse插件, 设定wtp版本 -->            <plugin>                <groupId>org.apache.maven.plugins</groupId>                <artifactId>maven-eclipse-plugin</artifactId>                <version>2.9</version>                <configuration>                    <downloadSources>true</downloadSources>                    <downloadJavadocs>false</downloadJavadocs>                    <wtpversion>2.0</wtpversion>                </configuration>            </plugin>            <plugin>                <groupId>org.apache.maven.plugins</groupId>                <artifactId>maven-dependency-plugin</artifactId>                <executions>                    <execution>                        <id>install</id>                        <phase>install</phase>                        <goals>                            <goal>sources</goal>                        </goals>                    </execution>                </executions>            </plugin>            <!-- 用于支持跨模块加载配置文件 -->            <plugin>                <groupId>org.apache.maven.plugins</groupId>                <artifactId>maven-resources-plugin</artifactId>                <version>2.5</version>                <configuration>                    <encoding>UTF-8</encoding>                    <nonFilteredFileExtensions>                        <nonFilteredFileExtension>dll</nonFilteredFileExtension>                        <nonFilteredFileExtension>so</nonFilteredFileExtension>                    </nonFilteredFileExtensions>                </configuration>            </plugin>        </plugins>    </build>

• 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
  
  基于maven的ssh框架一步一步搭建

三、将spring 整合进来

• 1、web.xml加入spring监听

<context-param>        <param-name>contextConfigLocation</param-name>        <param-value>classpath*:META-INF/spring/ApplicationContext.xml</param-value>    </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

<?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="loginController">            <result name="success">/pages/index.jsp</result>        </action>    </package></struts>

（2）添加spring配置文件

<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

<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

<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

<!-- 添加Hibernate依赖 -->        <dependency>            <groupId>org.hibernate</groupId>            <artifactId>hibernate</artifactId>            <version>3.2.6.ga</version>            <type>jar</type>            <scope>compile</scope>            <exclusions>                <exclusion>                    <artifactId>jta</artifactId>                    <groupId>javax.transaction</groupId>                </exclusion>            </exclusions>        </dependency>        <dependency>            <groupId>org.hibernate</groupId>            <artifactId>hibernate-annotations</artifactId>            <version>3.2.0.ga</version>            <type>jar</type>            <scope>compile</scope>        </dependency>        <dependency>            <groupId>org.hibernate</groupId>            <artifactId>ejb3-persistence</artifactId>            <version>1.0.0</version>        </dependency><dependency>        <groupId>mysql</groupId>        <artifactId>mysql-connector-java</artifactId>        <version>5.0.5</version></dependency>

• 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
