JavaWeb_(SSH)三大框架整合struts+hibernate+spring_Demo
三大框架整合
一、SSH导包
二、书写Spring
三、书写Struts
四、整合Spring与Struts
五、书写（与整合）Hibernate、引入c3p0连接池并使用hibernate模板
六、整合事务
--完成用户登录
项目已上传到github 传送门
在MySQL数据库中创建spring表，添加一条假数据
一、SSH导包
导入struts的jar包
导入spring的jar包
导入hibernate的jar包
导入c3p0连接池jar包和springapo的jar包，mysql链接数据库驱动包，第四个spring整合包暂时不需要导入，下文导入的时候会说！！！
二、书写Spring
准备applicationContext.xml作为spring的配置文件
<?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:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
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/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd"> </beans>
applicationContext.xml
编写web.xml
<!-- 让spring随着web项目的启动而启动 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener> <!-- 读取配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">

</listener> <!-- 读取配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param> </web-app>
web.xml
三、配置struts
准备struts.xml配置文件
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
"http://struts.apache.org/dtds/struts-2.5.dtd"> <struts>
</struts>
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
"http://struts.apache.org/dtds/struts-2.5.dtd"> <struts>
</struts>
struts.xml
在web.xml中开启struts
<!-- 让struts启动 -->
<filter>
<filter-name>struts</filter-name>
<filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
<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> <!-- 让spring随着web项目的启动而启动 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener> <!-- 读取配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param> <!-- 让struts启动 -->
<filter>
<filter-name>struts</filter-name>
<filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping> </web-app>
web.xml
四.1、书写Action，并在struts.xml中开启动态方法调用
package com.Gary.domain;
public class User {
private String id;
private String username;
private String password;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
User.java
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> <!-- 配置包名字 -->
<hibernate-mapping package="com.Gary.domain">
<!-- 配置包类和数据库中的哪个表对应 -->
<class name="User" table="user">
<!-- 主键 -->
<id name="id">

</id> <!-- 普通字段 -->
<property name="username" column="username"></property>
<property name="password" column="password"></property> </class> </hibernate-mapping>
User.hbm.xml
package com.Gary.web; import com.Gary.domain.User;
import com.Gary.service.UserService;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven; public class UserAction extends ActionSupport implements ModelDriven<User>{ public User user = new User(); private UserService userService; public String execute() throws Exception { boolean success = userService.findUser(user); if(success)
{
return "toIndex";
}else {
ActionContext.getContext().put("error", "用户名或密码错误！！！");
return "login";
} } public UserService getUserService() {
return userService;
} public void setUserService(UserService userService) {
this.userService = userService;
} @Override
public User getModel() {
return user;
} }
UserAction.java
package com.Gary.service; import com.Gary.dao.UserDao;
import com.Gary.domain.User; public class UserService { private UserDao userDao; public boolean findUser(User user) { User temp = userDao.findUser(user); return temp == null?false:true;
} public UserDao getUserDao() {
return userDao;
} public void setUserDao(UserDao userDao) {
this.userDao = userDao;
} }
UserService.java
package com.Gary.dao; import org.hibernate.Session;
import org.hibernate.query.NativeQuery;
import org.springframework.orm.hibernate5.support.HibernateDaoSupport; import com.Gary.domain.User; public class UserDao extends HibernateDaoSupport { public User findUser(User user) {
Session session = getHibernateTemplate().getSessionFactory().getCurrentSession(); String sql = "select * from user where username = ? and password = ?";
NativeQuery query = session.createSQLQuery(sql);
query.setParameter(1,user.getUsername());
query.setParameter(2, user.getPassword());
query.addEntity(User.class); User result = (User) query.uniqueResult(); return result;
} }
UserDao.java

</body>
login.jsp
四.2、整合Spring与Struts
导入struts2-spring-plugin-2.5.16.jar整合包
在stuts.xml中让spring管理Action的创建
<!-- 让spring管理Action的创建 -->
<constant name="struts.objectFactory" value="spring"></constant>
在applicationContext.xml中配置web层、service层、dao层的<bean>元素
<!-- 配置userAciton -->
<bean name="userAction" class="com.Gary.web.UserAction" scope="prototype">
<!-- 注入userService -->
<property name="userService" ref="userService"></property>
</bean> <!-- 配置userService -->
<bean name="userService" class="com.Gary.service.UserService">
<!-- 注入userDao -->
<property name="userDao" ref="userDao"></property>
</bean> <!-- 配置userDao -->
<bean name="userDao" class="com.Gary.dao.UserDao">
<!-- 注入sessionFactory (用到了HibernateDaoSupport) -->
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<!-- 注入sessionFactory (用到了HibernateDaoSupport) -->
<property name="sessionFactory" ref="sessionFactory"></property>
</bean> </beans>
applicationContext.xml
五、整合Hibernate、引入连接池并使用hibernate模板
在applicationContext.xml中整合Hibernate
<bean name="dataSource"
class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="jdbcUrl" value="jdbc:mysql:///spring"></property>
<property name="driverClass" value="com.mysql.jdbc.Driver"></property>
<property name="user" value="root"></property>
<property name="password" value="123456"></property>
</bean> <!-- 配置sesisonFactory -->
<bean name="sessionFactory"
class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
<!-- 配置dataSource -->
<property name="dataSource" ref="dataSource"></property>
<!-- 配置基本属性 -->
<property name="hibernateProperties">
<props>
<!-- 方言 -->
<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>
<!-- 生成表策略 -->
<prop key="hibernate.hbm2ddl.auto">update</prop>
<!-- 是否生成sql语句 -->
<prop key="hibernate.show_sql">true</prop>
<!-- 是否格式化sql -->
<prop key="hibernate.format_sql">true</prop>
</props>
</property>
<!-- 读取orm元数据 -->
<property name="mappingDirectoryLocations"
value="classpath:com/Gary/domain"></property> </bean>
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<bean name="userDao" class="com.Gary.dao.UserDao">
<!-- 注入sessionFactory (用到了HibernateDaoSupport) -->
<property name="sessionFactory" ref="sessionFactory"></property>
</bean> </beans>
applicationContext.xml
在web.xml中扩大session范围【扩大session范围<filter>一定要放在启动struts上】
<!-- 扩大session范围 -->
<filter>
<filter-name>openSessionInView</filter-name>
<filter-class>org.springframework.orm.hibernate5.support.OpenSessionInViewFilter</filter-class>

<url-pattern>/*</url-pattern>
</filter-mapping> </web-app>
web.xml
六、整合事务
在applicationContext.xml中配置事务
<!-- 事务的核心管理器 -->
<bean name="transactionManager"
class="org.springframework.orm.hibernate5.HibernateTransactionManager">
<!-- 需要sessionFactory -->
<property name="sessionFactory" ref="sessionFactory"></property>
</bean> <!-- 通知 -->
<tx:advice id="advice"
