基于注解的Spring MVC整合Hibernate（所需jar包，spring和Hibernate整合配置，springMVC配置，重定向，批量删除）

大家好，又见面了，我是全栈君。

1、导入jar

2、web.xml配置

<?xml version=”1.0″ encoding=”UTF-8″?>
<web-app version=”2.4″
xmlns=”http://java.sun.com/xml/ns/j2ee“
xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance“
xsi:schemaLocation=”http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd“>

<!– 通过上下文參数指定spring配置文件的位置 –>
<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>classpath:beans.xml</param-value>
</context-param>
<listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<servlet>
  <servlet-name>action</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <init-param>
   <param-name>contextConfigLocation</param-name>
   <param-value>classpath:springMVC.xml</param-value>
  </init-param>
</servlet>
<servlet-mapping>
  <servlet-name>action</servlet-name>
  <url-pattern>/</url-pattern>
</servlet-mapping>
<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
3、bean.xml配置

<?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:mvc=”http://www.springframework.org/schema/mvc“
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/mvc
      http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
      http://www.springframework.org/schema/context
      http://www.springframework.org/schema/context/spring-context-3.0.xsd
      http://www.springframework.org/schema/aop
      http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
      http://www.springframework.org/schema/tx
      http://www.springframework.org/schema/tx/spring-tx-3.0.xsd “>
<!– 注解驱动 –>
<mvc:annotation-driven/>
<!– 组件扫描 –>
<context:component-scan base-package=”cn.itcast.springmvc”></context:component-scan>

<!– 定义数据源 –>
<bean id=”ds” class=”com.mchange.v2.c3p0.ComboPooledDataSource”>
  <property name=”driverClass” value=”com.mysql.jdbc.Driver”></property>
  <property name=”jdbcUrl” value=”jdbc:mysql://localhost:3306/springmvc”></property>
  <property name=”user” value=”root”></property>
  <property name=”password” value=”123456″></property>
  <property name=”initialPoolSize” value=”10″></property>
  <property name=”maxPoolSize” value=”50″></property>
  <property name=”minPoolSize” value=”10″></property>
</bean>

<bean id=”sessionFactory” class=”org.springframework.orm.hibernate3.LocalSessionFactoryBean”>
  <property name=”dataSource” ref=”ds”></property>

  <!– hibernate映射文件的位置 –>
  <property name=”mappingDirectoryLocations”>
   <value>classpath:cn/itcast/springmvc/domain/</value>
  </property>
  <property name=”hibernateProperties”>
   <props>
    <prop key=”hibernate.Dialect”>org.hibernate.dialect.MySQLInnoDBDialect</prop>
    <prop key=”hibernate.show_sql”>true</prop>
    <prop key=”hibernate.hbm2ddl.auto”>update</prop>
   </props>
  </property>
</bean>

<!– 配置事物管理器 –>
<bean id=”txManager” class=”org.springframework.orm.hibernate3.HibernateTransactionManager”>
  <property name=”sessionFactory” ref=”sessionFactory”/>
</bean>

<!– 配置事物的传播特性 (事物通知)–>
<tx:advice id=”txAdvice” transaction-manager=”txManager”>
  <tx:attributes>
   <tx:method name=”save*” propagation=”REQUIRED”/>
   <tx:method name=”delete*” propagation=”REQUIRED”/>
   <tx:method name=”update*” propagation=”REQUIRED”/>
   <tx:method name=”find*” read-only=”true”/>
   <tx:method name=”*” read-only=”true”/>
  </tx:attributes>
</tx:advice>

<aop:config>
  <aop:advisor pointcut=”execution(* *..*ServiceImpl.*(..))” advice-ref=”txAdvice”/>
  <!–
   <aop:advisor advice-ref=”txAdvice” pointcut=”execution(* *..*ServiceImpl.*(..))”/>
   –>
</aop:config>
</beans>

4、SpringMVC.xml配置

5、domain和hbm.xml配置

package cn.itcast.springmvc.domain;

public class Person {

private String id;
private String name;
private Integer age;
private String address;
public String getId() {
  return id;
}
public void setId(String id) {
  this.id = id;
}
public String getName() {
  return name;
}
public void setName(String name) {
  this.name = name;
}
public Integer getAge() {
  return age;
}
public void setAge(Integer age) {
  this.age = age;
}
public String getAddress() {
  return address;
}
public void setAddress(String address) {
  this.address = address;
}
}

—————————-

Person.hbm.xml

xml version=”1.0″?>

}

public void savePerson(Person p) {
sf.getCurrentSession().save(p);
}

public void deletePersonById(String id) {
  Person p = new Person();
  p.setId(id);
