Struts2+Spring4 +Hibernate4
首先看看建立项目的框架
第一步 建立web项目
第二步 导入相对应需要的jar包（放在项目WEB-INFO/lib下）
需要导入Spring需要的，Struts2需要的，Hibernate需要的，mysQL连接驱动；
第三步 配置ssh各个的xml文件；
第四步 将log4j.dtd与log4j.xml放在WEB-INFO下：
log4j.xml
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE log4j:configuration SYSTEM "log4j.dtd"> 3 <log4j:configuration xmlns:log4j='http://jakarta.apache.org/log4j/'> 4 5 <appender name="STDOUT" class="org.apache.log4j.ConsoleAppender"> 6 <layout class="org.apache.log4j.PatternLayout"> 7 <param name="ConversionPattern" value="%c %d{yyyy-MM-dd HH:mm:ss} -- %p -- %m%n" /> 8 </layout> 9 </appender> 10 11 <appender name="DEBUG" class="org.apache.log4j.RollingFileAppender"> 12 <param name="File" value="${sshWeb.root}/sshWeb-debug.log" /> 13 <param name="Append" value="true" /> 14 <param name="MaxFileSize" value="10240KB" /> 15 <param name="MaxBackupIndex" value="1000" /> 16 <layout class="org.apache.log4j.PatternLayout"> 17 <param name="ConversionPattern" value="%c %d{yyyy-MM-dd HH:mm:ss} -- %p -- %m%n" /> 18 </layout> 19 <filter class="org.apache.log4j.varia.LevelRangeFilter"> 20 <param name="LevelMin" value="DEBUG" /> 21 <param name="LevelMax" value="DEBUG" /> 22 </filter> 23 </appender> 24 25 <appender name="INFO" class="org.apache.log4j.RollingFileAppender"> 26 <param name="File" value="${sshWeb.root}/sshWeb-info.log" /> 27 <param name="Append" value="true" /> 28 <param name="MaxFileSize" value="10240KB" /> 29 <param name="MaxBackupIndex" value="1000" /> 30 <layout class="org.apache.log4j.PatternLayout"> 31 <param name="ConversionPattern" value="%c %d{yyyy-MM-dd HH:mm:ss} -- %p -- %m%n" /> 32 </layout> 33 <filter class="org.apache.log4j.varia.LevelRangeFilter"> 34 <param name="LevelMin" value="INFO" /> 35 <param name="LevelMax" value="INFO" /> 36 </filter> 37 </appender> 38 39 <appender name="WARN" class="org.apache.log4j.RollingFileAppender"> 40 <param name="File" value="${sshWeb.root}/sshWeb-warn.log" /> 41 <param name="Append" value="true" /> 42 <param name="MaxFileSize" value="10240KB" /> 43 <param name="MaxBackupIndex" value="1000" /> 44 <layout class="org.apache.log4j.PatternLayout"> 45 <param name="ConversionPattern" value="%c %d{yyyy-MM-dd HH:mm:ss} -- %p -- %m%n" /> 46 </layout> 47 <filter class="org.apache.log4j.varia.LevelRangeFilter"> 48 <param name="LevelMin" value="WARN" /> 49 <param name="LevelMax" value="WARN" /> 50 </filter> 51 </appender> 52 53 <appender name="ERROR" class="org.apache.log4j.RollingFileAppender"> 54 <param name="File" value="${sshWeb.root}/sshWeb-error.log" /> 55 <param name="Append" value="true" /> 56 <param name="MaxFileSize" value="10240KB" /> 57 <param name="MaxBackupIndex" value="1000" /> 58 <layout class="org.apache.log4j.PatternLayout"> 59 <param name="ConversionPattern" value="%c %d{yyyy-MM-dd HH:mm:ss} -- %p -- %m%n" /> 60 </layout> 61 <filter class="org.apache.log4j.varia.LevelRangeFilter"> 62 <param name="LevelMin" value="ERROR" /> 63 <param name="LevelMax" value="ERROR" /> 64 </filter> 65 </appender> 66 67 <root> 68 <priority value="INFO" /> 69 <appender-ref ref="STDOUT" /> 70 <appender-ref ref="DEBUG" /> 71 <appender-ref ref="INFO" /> 72 <appender-ref ref="WARN" /> 73 <appender-ref ref="ERROR" /> 74 </root> 75 76 </log4j:configuration>

第五步 配置web.xml文件
<?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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>SSH</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> <!-- web应用一启动，便加载spring容器 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/classes/applicationContext.xml</param-value> </context-param> <!-- 动态设置项目的运行路径 --> <context-param> <param-name>webAppRootKey</param-name> <param-value>sshWeb.root</param-value> </context-param> <!-- 加载LOG4J --> <context-param> <param-name>log4jConfigLocation</param-name> <param-value>/WEB-INF/log4j.xml</param-value> </context-param> <context-param> <param-name>log4jRefreshInterval</param-name> <param-value>60000</param-value> </context-param> <!-- 配置Hibernate过滤器 --> <filter> <filter-name>hibernateFilter</filter-name> <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class> <init-param> <param-name>sessionFactoryBeanName</param-name> <param-value>sessionFactory</param-value> </init-param> <init-param> <param-name>singleSession</param-name> <param-value>true</param-value> </init-param> <init-param> <param-name>flushMode</param-name> <param-value>AUTO</param-value> </init-param> </filter> <filter-mapping> <filter-name>hibernateFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 字符集过滤 --> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 登录过滤 --> <filter> <filter-name>loginFilter</filter-name> <filter-class>com.cy.ssh.filter.LoginFilter</filter-class> </filter> <filter-mapping> <filter-name>loginFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 加载spring容器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 加载log4j文件 --> <listener> <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener> </web-app>
第六步 来配置ssh各个的xml文件，
先配置 applicationContext.xml
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:p="http://www.springframework.org/schema/p" 5 xmlns:aop="http://www.springframework.org/schema/aop" 6 xmlns:tx="http://www.springframework.org/schema/tx" 7 xmlns:mvc="http://www.springframework.org/schema/mvc" 8 xmlns:context="http://www.springframework.org/schema/context" 9 xsi:schemaLocation="http://www.springframework.org/schema/beans 10 http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 11 http://www.springframework.org/schema/context 12 http://www.springframework.org/schema/context/spring-context-3.0.xsd 13 http://www.springframework.org/schema/aop 14 http://www.springframework.org/schema/aop/spring-aop-3.0.xsd 15 http://www.springframework.org/schema/tx 16 http://www.springframework.org/schema/tx/spring-tx-3.0.xsd 17 http://www.springframework.org/schema/mvc 18 http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> 19 <!-- 开启spring自动扫描功能，适用注解 --> 20 <context:component-scan base-package="com.cy.ssh" /> 21 22 <!-- 配置C3P0数据源 --> 23 <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close"> 24 <property name="driverClass" value="com.mysql.jdbc.Driver" /> 25 <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/mybatis?characterEncoding=utf-8" /> 26 <property name="user" value="root" /> 27 <property name="password" value="root" /> 28 <property name="minPoolSize" value="1" /> 29 <property name="maxPoolSize" value="20" /> 30 <property name="initialPoolSize" value="1" /> 31 <property name="maxIdleTime" value="60" /> 32 <property name="acquireIncrement" value="5" /> 33 <property name="automaticTestTable" value="c3p0TestTable" /> 34 <property name="idleConnectionTestPeriod" value="60" /> 35 <property name="checkoutTimeout" value="3000" /> 36 </bean> 37 38 <!-- 配置SessionFactory --> 39 <bean id="sessionFactory" 40 class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> 41 <!-- 向SessionFactory中注入数据源 --> 42 <property name="dataSource" ref="dataSource" /> 43 <property name="hibernateProperties"> 44 <props> 45 <!-- 定义Hibernate的方言 --> 46 <prop key="hibernate.dialect"> 47 org.hibernate.dialect.MySQLDialect 48 </prop> 49 <!-- 是否根据需要每次自动更新数据库 50 <prop key="hibernate.hbm2ddl.auto">update</prop> --> 51 <!-- 控制台显示SQL --> 52 <prop key="hibernate.show_sql">true</prop> 53 <prop key="hibernate.format_sql">true</prop> 54 <!-- 使用SQL注释 --> 55 <prop key="hibernate.use_sql_comments">true</prop> 56 </props> 57 </property> 58 59 <!-- 浏览bean包下的所有使用Hibernate注解的JavaBean --> 60 <property name="packagesToScan"> 61 <list> 62 <value>com.cy.ssh.beans</value> 63 </list> 64 </property> 65 </bean> 66 67 <!-- spring通过声明式方式来进行事务管理--> 68 <bean id="transactionManager" 69 class="org.springframework.orm.hibernate4.HibernateTransactionManager"> 70 <property name="sessionFactory" ref="sessionFactory"/> 71 </bean> 72 73 74 <!-- 定义个通知，指定事务管理器 --> 75 <tx:advice id="txAdvice" transaction-manager="transactionManager"> 76 <tx:attributes> 77 <tx:method name="delete*" propagation="REQUIRED" read-only="false" 78 rollback-for="java.lang.Exception" /> 79 <tx:method name="save*" propagation="REQUIRED" read-only="false" 80 rollback-for="java.lang.Exception" /> 81 <tx:method name="update*" propagation="REQUIRED" read-only="false" 82 rollback-for="java.lang.Exception" /> 83 <tx:method name="load*" propagation="SUPPORTS" read-only="true"/> 84 <tx:method name="find*" propagation="SUPPORTS" read-only="true"/> 85 <tx:method name="select*" propagation="SUPPORTS" read-only="true"/> 86 <tx:method name="get*" propagation="SUPPORTS" read-only="true"/> 87 </tx:attributes> 88 </tx:advice> 89 90 <aop:config> 91 <!-- 配置一个切入点 --> 92 <aop:pointcut id="serviceMethods" 93 expression="execution(* com.cy.ssh.service.impl.*ServiceImpl.*(..))" /> 94 <aop:advisor advice-ref="txAdvice" 95 pointcut-ref="serviceMethods" /> 96 </aop:config> 97 98 </beans>
配置都差不多了。
来写个登录案例
User.java 使用Hibernate注解
1 package com.cy.ssh.beans; 2 3 import java.io.Serializable; 4 import javax.persistence.Column; 5 import javax.persistence.Entity; 6 import javax.persistence.GeneratedValue; 7 import javax.persistence.Id; 8 import javax.persistence.Table; 9 10 import org.hibernate.annotations.GenericGenerator; 11 /** 12 * 用户 13 * @author acer 14 * 15 */ 16 @Entity 17 @Table(name="t_user") 18 public class User implements Serializable { 19 20 private static final long serialVersionUID = 1L; 21 @Id 22 @Column(name="id") 23 @GenericGenerator(name="hbincrement", strategy="increment") 24 @GeneratedValue(generator="hbincrement") 25 private int id; 26 @Column(name="username",length=20) 27 private String username; 28 @Column(name="password",length=32) 29 private String password; 30 @Column(name="age") 31 private int age; 32 @Column(name="flag") 33 private int flag; 34 35 public User(){ 36 37 } 38 39 public int getId() { 40 return id; 41 } 42 43 public void setId(int id) { 44 this.id = id; 45 } 46 47 public String getUsername() { 48 return username; 49 } 50 51 public void setUsername(String username) { 52 this.username = username; 53 } 54 55 public String getPassword() { 56 return password; 57 } 58 59 public void setPassword(String password) { 60 this.password = password; 61 } 62 63 public int getAge() { 64 return age; 65 } 66 67 public void setAge(int age) { 68 this.age = age; 69 } 70 71 public int getFlag() { 72 return flag; 73 } 74 75 public void setFlag(int flag) { 76 this.flag = flag; 77 } 78 79 @Override 80 public String toString() { 81 return "User [id=" + id + ", username=" + username + ", password=" 82 + password + ", age=" + age + ", flag=" + flag + "]"; 83 } 84 85 86 87 }
工具类：
HibernateTools.java
1 package com.cy.ssh.tools; 2 3 import org.hibernate.Session; 4 import org.hibernate.SessionFactory; 5 import org.springframework.beans.factory.annotation.Autowired; 6 import org.springframework.beans.factory.annotation.Qualifier; 7 import org.springframework.stereotype.Component; 8 /** 9 * 10 * @author acer 11 * 12 */ 13 @Component 14 public class HibernateTools { 15 16 @Autowired 17 @Qualifier("sessionFactory") 18 private SessionFactory sessionFactory; 19 public void setSessionFactory(SessionFactory sessionFactory) { 20 this.sessionFactory = sessionFactory; 21 } 22 23 public Session getSession(){ 24 return sessionFactory.getCurrentSession(); 25 } 26 27 public Session getNewSession(){ 28 return sessionFactory.openSession(); 29 } 30 31 }
StringTools.java
1 package com.cy.ssh.tools; 2 /** 3 * 判断是否为空 4 * @author acer 5 * 6 */ 7 public class StringTools { 8 9 public static boolean isNull(String str){ 10 if(str == null || "".equals(str)){ 11 return true; 12 } 13 return false; 14 } 15 }
