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

<?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

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
