開發SSH項目的時候搭建開發環境是一項很重要的工作，這篇博客從下載jar包開始一步一步在eclipse中進行配置。配置jdk、安裝eclipse、tomact相信每一個學習ssh框架的同學都輕車熟路，不熟悉的同學請自行百度之。 個人機器及軟件配置： > 操作系統：Windows 7 64位 jdk：1.7 tomact：6.0 eclipse：: Luna Service Release 2 (4.4.2) ### 一.下載好jar包 首先下載好struts 2.3.4、spring 4.2.3、hibernate4.3.11、commons-logging、mysql驅動、c3p0 1. struts 2下載地址 [http://struts.apache.org/index.html](http://struts.apache.org/index.html) 2. spring下載地址[http://repo.springsource.org/libs-release-local/org/springframework/spring/](http://repo.springsource.org/libs-release-local/org/springframework/spring/) 3. hibernate下載地址[http://hibernate.org/orm/downloads/](http://hibernate.org/orm/downloads/) 4. commons-logging下載地址[http://commons.apache.org/proper/commons-logging/download_logging.cgi](http://commons.apache.org/proper/commons-logging/download_logging.cgi)，下載commons-logging-1.2-bin.zip 5. mysql驅動下載地址[http://dev.mysql.com/downloads/connector/j/](http://dev.mysql.com/downloads/connector/j/) 6. c3p0地址地址[[http://mvnrepository.com/artifact/c3p0/c3p0][http://mvnrepository.com/artifact/c3p0/c3p0]](http://mvnrepository.com/artifact/c3p0/c3p0][http://mvnrepository.com/artifact/c3p0/c3p0]) 下載好后分別解壓，lstruts-2.3.24-all、spring-framework-4.2.3.RELEASE-dist、hibernate-release-4.3.10.Final、commons-logging-1.2-bin這幾個文件夾內放的都是需要的jar包，以后我們需要加入配置文件的時候就從這幾個文件夾內取。 ### 二、安裝eclipse插件 打開eclipse，找到help->eclipse marketplace，分別搜索 hibernate、spring，安裝hibernate tools插件和spring tool suite插件。 ### 三、新建動態web工程 打開eclipse，新建dynamic web project，project name可以自定義，target runtime選擇Apache tomact 6.0，dynamic web module version選擇2.5.finish. 在webcontent目錄下新建index.jsp，tomcat中運行，文件目錄及運行效果如下：  ### 四、加入spring 首先加入spring，需要下面這三個步驟：加入jar包、配置web.xml、加入spring配置文件 1. 加入jar包 打開spring-framework-4.2.3.RELEASE-dist\spring-framework-4.2.3.RELEASE\libs文件夾，復制以下jar包到WebContent/WEB-INF/lib： > spring-aspects-4.2.3.RELEASE.jar spring-beans-4.2.3.RELEASE.jar spring-context-4.2.3.RELEASE.jar spring-core-4.2.3.RELEASE.jar spring-expression-4.2.3.RELEASE.jar spring-instrument-4.2.3.RELEASE.jar spring-jdbc-4.2.3.RELEASE.jar spring-jms-4.2.3.RELEASE.jar spring-messaging-4.2.3.RELEASE.jar spring-orm-4.2.3.RELEASE.jar spring-test-4.2.3.RELEASE.jar spring-tx-4.2.3.RELEASE.jar spring-web-4.2.3.RELEASE.jar spring-webmvc-4.2.3.RELEASE.jar spring-websocket-4.2.3.RELEASE.jar 打開commons-logging-1.2，找到commons-logging-1.2.jar，復制到lib目錄下.然后選中所有jar包，add to build path. 2.配置web.xml 打開web.xml,安裝spring tools插件后按alt+/自動補全鍵會提示，向上找到ContextLoaderListener.會自動生成以下代碼： ~~~ <!-- needed for ContextLoaderListener --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>location</param-value> </context-param> <!-- Bootstraps the root web application context before servlet initialization --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> ~~~ 3.加入spring配置文件 點擊工程名，新建source folder(注意：不是folder),命名為conf，用來存放配置文件.在conf目錄下新建Spring Bean Definition file,名稱為applicationContext.xml.將web.xml中spring配置中的location改為：classpath:applicationContext.xml. ~~~ <!-- needed for ContextLoaderListener --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!-- Bootstraps the root web application context before servlet initialization --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> ~~~ ### 五、設置c3p0數據庫連接池 1.加入c3p0和mysql連接驅動.把下面兩個jar包加到lib目錄，每次加入新的jar包都要add to build path. > c3p0-0.9.1.2.jar mysql-connector-java-5.1.38-bin.jar 2.在conf目錄下新建資源文件 添加db.properties文件 ~~~ jdbc.user=root jdbc.password=123456 jdbc.driverClass=com.mysql.jdbc.Driver jdbc.jdbcUrl=jdbc:mysql:///sshdb jdbc.initPoolSize=5 jdbc.maxPoolSize=10 ~~~ 更新applicationContext.xml ~~~ <?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:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd"> <!-- 導入資源文件 --> <context:property-placeholder location="classpath:db.properties" /> <!-- 配置C3P0數據源 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="user" value="${jdbc.user}"></property> <property name="password" value="${jdbc.password}"></property> <property name="driverClass" value="${jdbc.driverClass}"></property> <property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property> <property name="initialPoolSize" value="${jdbc.initPoolSize}"></property> <property name="maxPoolSize" value="${jdbc.maxPoolSize}"></property> </bean> <bean id="sessionFactorys" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource"></property> <property name="configLocation" value="classpath:hibernate.cfg.xml"></property> <property name="mappingLocations" value="classpath:cn/ac/ucas/form/*.hbm.xml"></property> </bean> </beans> ~~~ ### 六、spring整合hibernate 1. 加入jar包 將hibernate-release-4.3.10.Final\lib\required目錄下的jar包全部copy到工程lib目錄下. 1. 添加hibernate配置文件 在conf目錄下新建hibernate.cfg.xml，并配置hibernate基本屬性. ~~~ <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <!-- 配置hibernate基本屬性 --> <!-- 方言 ctrl+shift+t 輸入mysql5，找到org.hibernate.dialect.MySQL5InnoDBDialect--> <property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property> <!-- 是否顯示格式化sql --> <property name="hibernate.show_sql">true</property> <property name="hibernate.format_sql">true</property> <!-- 生成數據表的策略 --> <property name="hibernate.hbm2ddl.auto">update</property> <!--二級緩存配置相關 --> </session-factory> </hibernate-configuration> ~~~ ###七.創建持久化類 1. 新建cn.ac.ucas.form包，里面新建兩個類. 員工所屬部門類： ~~~ package cn.ac.ucas.form; public class Department { private Integer id; private String departmentName;//部門名稱 public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getDepartmentName() { return departmentName; } public void setDepartmentName(String departmentName) { this.departmentName = departmentName; } } ~~~ 員工信息類： ~~~ package cn.ac.ucas.form; import java.util.Date; public class Employee { // id不能修改 private Integer id; private String lastName; private String email; // 從前端傳來的是string類型,需要注意轉換 private Date birth; // 創建時間不能被修改 private Date createTime; // 單向多對一的關聯關系. private Department department; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getLastName() { return lastName; } public void setLastName(String lastName) { this.lastName = lastName; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } public Date getBirth() { return birth; } public void setBirth(Date birth) { this.birth = birth; } public Date getCreateTime() { return createTime; } public void setCreateTime(Date createTime) { this.createTime = createTime; } public Department getDepartment() { return department; } public void setDepartment(Department department) { this.department = department; } } ~~~ 點擊包名,new->other->hibernate->hibernate xml mapping file，會自動生成持久化類對應的.hbm.xml文件. Department.hbm.xml ~~~ <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <!-- Generated 2015-12-15 12:07:42 by Hibernate Tools 3.4.0.CR1 --> <hibernate-mapping> <class name="cn.ac.ucas.form.Department" table="SSH_DEPARTMENT"> <id name="id" type="java.lang.Integer"> <column name="ID" /> <generator class="native" /> </id> <property name="departmentName" type="java.lang.String"> <column name="DEPARTMENT_NAME" /> </property> </class> </hibernate-mapping> ~~~ Employee.hbm.xml ~~~ <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <!-- Generated 2015-12-15 12:07:42 by Hibernate Tools 3.4.0.CR1 --> <hibernate-mapping> <class name="cn.ac.ucas.form.Employee" table="SSH_EMPLOYEE"> <id name="id" type="java.lang.Integer"> <column name="ID" /> <generator class="native" /> </id> <property name="lastName" type="java.lang.String"> <column name="LASTNAME" /> </property> <property name="email" type="java.lang.String"> <column name="EMAIL" /> </property> <property name="birth" type="java.util.Date"> <column name="BIRTH" /> </property> <property name="createTime" type="java.util.Date"> <column name="CREATETIME" /> </property> <many-to-one name="department" class="cn.ac.ucas.form.Department" fetch="join"> <column name="DEPARTMENT" /> </many-to-one> </class> </hibernate-mapping> ~~~ 運行項目，成功的話會在數據庫中生成數據庫表.  ###八.spring整合struts 1.加入jar包 把struts-2.3.24\apps\struts2-blank\WEB-INF\lib目錄下的jar拷貝到工程lib目錄下. web.xml中加入下面代碼： ~~~ <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> ~~~ 至此ssh項目環境配置已經完成. 代碼下載地址：[http://download.csdn.net/detail/napoay/9358803](http://download.csdn.net/detail/napoay/9358803)
