ssh框架的搭建,后面再基于maven搭建补全:
Xml配置
1. spring整合hibernate框架(xml文件配置)
spring的配置文件:applicationContext.xml
hibernate的配置文件:hibernate.cfg.xml
struts2的配置文件:struts.xml
数据库链接配置:db.properties
2) . 实体类下 xxx.hbm.xml 文件
<?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">
<hibernate-mapping>
<!-- 创建类和表的对于关系 -->
<class name="com.web.domain.User" table="t_user">
<id name="id">
<generator class="identity"></generator>
</id>
<property name="name"></property>
<property name="age"></property>
</class>
</hibernate-mapping>
3)在applicationContext.xml文件中配置hibernate的相关配置
A.设置数据源
B.设置hibernate相关配置
C.加载hbm.xml配置文件内容
<!-- 加载properties文件 -->
<context:property-placeholder location="classpath:db.properties" />
<!-- 配置连接池 -->
<bean id="c3p0DataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${jdbc.driverClass}" />
<property name="jdbcUrl" value="${jdbc.url}" />
<property name="user" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
</bean>
<!-- 将hibernate相关配置写在spring的配置文件中 -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
<!-- 加载连接池 -->
<property name="dataSource" ref="c3p0DataSource"></property>
<property name="hibernateProperties">
<!-- 加载hibernate配置 -->
<props>
<prop key="hibernate.show_sql">true</prop> <!-- 可以将向数据库发送的sql显示出来 -->
<prop key="hibernate.format_sql">true</prop> <!-- 格式化sql -->
<prop key="hibernate.hbm2ddl.auto">update</prop> <!-- 自动创建表 -->
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> <!-- hibernate的方言 -->
</props>
</property>
<!-- 加载hbm配置文件 -->
<property name="mappingResources">
<list>
<value>com/web/domain/User.hbm.xml</value>
</list>
</property>
</bean>
2. spring整合struts2框架(xml文件配置)
1).在applicationContext.xml配置文件中添加dao和service
<bean id="userDao" class="com.web.dao.UserDaoImpl"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 声明service --> <bean id="userService" class="com.web.service.UserServiceImpl"> <property name="userDao" ref="userDao"></property> </bean>
2).applicationContext.xml中设置事务管理
<!-- 通知 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="find*" read-only="true"/>
<tx:method name="add"/>
<tx:method name="update"/>
<tx:method name="delete"/>
</tx:attributes>
</tx:advice>
<!-- 切面 -->
<aop:config>
<aop:pointcut expression="execution(* com.web.service..*(..))" id="myPointcut"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="myPointcut"/>
</aop:config>
<!-- spring管理struts框架 -->
<bean id="userAction" class="com.web.action.UserAction">
<property name="userService" ref="userService"></property>
</bean>3).struts.xml文件
<package name="default" extends="struts-default" namespace="/"> <action name="user_*" class="userAction" method="add"> <result name="success">/success.jsp</result> </action> </package>
4).web.xml文件的配置
<!-- spring框架的相关配置 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- struts核心拦截器的配置 --> <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>
注解配置
Web.xml文件中的内容和xml整合的内容一样
1. 在applicationContext.xml文件中,开启识别注解
<!-- 开启注解扫描 -->
<context:component-scan base-package="com.web"></context:component-scan>
2.domain实体类的注解
@Entity //定义一个实体类
@Table(name="t_user",catalog="sshtest")
public class User {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY) //主键生成策略
private int id;
@Column
private String name;
private int age;
3. Dao的注解
@Repository("userDao")
public class UserDaoImpl extends HibernateDaoSupport implements IUserDao {
@Autowired
@Qualifier("sessionFactory")
public void setSuperSessionFactory(SessionFactory factory){
super.setSessionFactory(factory);
@Override
public void add(User user) {
this.getHibernateTemplate().save(user); // session.save()
}
4. Service的注解
@Service("userService")
@Transactional //事务管理
public class UserServiceImpl implements IUserService {
@Autowired
@Qualifier("userDao")
private IUserDao userDao;
5. Action的注解(注意struts.xml文件中必须有struts标签)
@Controller
@Scope("prototype")
@Namespace("/")
@ParentPackage("struts-default")
类上的注解
方法上的注解
@Action(value="user_add",results={@Result(name="success",location="/success.jsp")})
<!-- 加载properties文件 -->
<context:property-placeholder location="classpath:db.properties" />
<!-- 开启注解扫描 -->
<context:component-scan base-package="com.web"></context:component-scan>
<!-- 配置连接池 -->
<bean id="c3p0DataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${jdbc.driverClass}" />
<property name="jdbcUrl" value="${jdbc.url}" />
<property name="user" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
</bean>
<!-- 将hibernate相关配置写在spring的配置文件中 -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
<!-- 加载连接池 -->
<property name="dataSource" ref="c3p0DataSource"></property>
<property name="hibernateProperties">
<!-- 加载hibernate配置 -->
<props>
<prop key="hibernate.show_sql">true</prop> <!-- 可以将向数据库发送的sql显示出来 -->
<prop key="hibernate.format_sql">true</prop> <!-- 格式化sql -->
<prop key="hibernate.hbm2ddl.auto">update</prop> <!-- 自动创建表 -->
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> <!-- hibernate的方言 -->
</props>
</property>
<!-- 加载注解类 -->
<property name="packagesToScan">
<list>
<value>com.web.domain</value>
</list>
</property>
</bean>
<!-- 事务管理 --> //如果不设置,底层默认是read-only
<bean id="transactionManager"
class="org.springframework.orm.hibernate5.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
<!-- 事务注解启动 -->
<tx:annotation-driven transaction-manager="transactionManager" />
