SpringMVC与Spring、Hibernate整合
本文采用正向工程
1.搭建工程
工程名称：mvcsh
2.添加支持的jar包
1).spring-3.2.0.jar
注：struts相关的jar不需要
\libs\*.jar
com.springsource.org.aopalliance-1.0.0.jar
com.springsource.org.aspectj.weaver-1.6.8.RELEASE.jar
commons-logging.jar
2).hibernate-distribution-3.6.10.Final.zip
\hibernate3.jar
lib\required\*.jar
backport-util-concurrent.jar
ehcache-1.5.0.jar
c3p0-0.9.1.jar
hibernate-jpa-2.0-api-1.0.1.Final.jar
log4j.jar
slf4j-log4j12-1.6.1.jar
mysql-connector-java-5.1.10-bin.jar
3.添加及修改相关配置文件
1).修改web.xml文件
a.添加spring监听与上下文
<!-- spring 监听器配置 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
b.添加springmvc的配置信息
<!-- springmvc的配置 -->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc-servlet.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
2).添加spring核心配置文件
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: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/tx http://www.springframework.org/schema/tx/spring-tx.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
</beans>
3).添加springmvc核心配置文件
springmvc-servlet.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-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/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
</beans>
4).在springmvc-servlet.xml中添加配置信息
a.扫描注解信息
<!-- 1.自动扫描注解 -->
<context:component-scan base-package="cn.jbit.mvcwithspring.web.annotation"></context:component-scan>
<mvc:annotation-driven/>
b.配置视图解析器
<!-- 2.视图解析器 -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 前缀 -->
<property name="prefix" value="/"></property>
<!-- 后缀 -->
<property name="suffix" value=".jsp"></property>
</bean>
5).添加属性文件jdbc.properties
jdbc.driver = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://localhost:3306/test
jdbc.user = root
jdbc.password =root
6).配置spring的配置，在applicationContext.xml文件中添加如下配置
<!-- 1.加载属性文件 -->
<context:property-placeholder location="classpath:jdbc.properties"/>
<!-- 2.自动描述注解 -->
<context:annotation-config/>
<context:component-scan base-package="cn.jbit"></context:component-scan>
<!-- 3.配置c3p0数据库连接池 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${jdbc.driver}"></property>
<property name="jdbcUrl" value="${jdbc.url}"></property>
<property name="user" value="${jdbc.user}"></property>
<property name="password" value="${jdbc.password}"></property>
</bean>
<!-- 4.配置SessionFactory -->
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<!-- 加载连接池 -->
<property name="dataSource" ref="dataSource"></property>
<!-- hibernate属性 -->
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">true</prop>
<prop key="hibernate.current_session_context_class">thread</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
</props>
</property>
<!-- 扫描注解po类所在的包 -->
<property name="packagesToScan">
<list>
<value>cn.jbit.mvcwithspring.domain</value>
</list>
</property>
</bean>
<!-- 5.配置Hibernater模板 -->
<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
<!-- 6.声明事务管理器 -->
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
<!-- 7.事务驱动 -->
<tx:annotation-driven transaction-manager="transactionManager"/>
4.实体类
/mvcsh/src/cn/jbit/mvcwithspring/domain/Student.java
@Entity
@Table(name="m_student")
public class Student implements Serializable {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private Integer studentNo;
private String studentName;
private Integer age;
//省略get和set方法
}
5.持久层
a.接口
public interface IStudentDao {
//添加
public void insert(Student student);
//查询
public List<Student> select();
}
b.实现类
@Repository
public class StudentDaoImpl implements IStudentDao {
@Autowired
private HibernateTemplate hibernateTemplate;
public void insert(Student student) {
this.hibernateTemplate.save(student);
}
public List<Student> select() {
return this.hibernateTemplate.find("FROM Student");
}
}
6.业务逻辑层
a.接口
public interface IStudentService {
public void save(Student student);
public List<Student> findAll();
}
b.实现类
@Service
@Transactional
public class StudentServiceImpl implements IStudentService {
@Autowired
private IStudentDao studentDao;
public void save(Student student) {
this.studentDao.insert(student);
}
public List<Student> findAll() {
return this.studentDao.select();
}
}
7.控制器
@Controller
@RequestMapping("/student")
public class StudentController {
@Autowired
private IStudentService studentService;
@RequestMapping("/save")
public String save(Student student){
this.studentService.save(student);
return "/savesuccess";
}
@RequestMapping("/list")
public String list(HttpServletRequest request){
List<Student> students = this.studentService.findAll();
request.setAttribute("students", students);
return "/list";
}
}
8.显示层
1).save.jsp
使用表单提交数据
2).list.jsp
<table>
<tr>
<td>学号</td>
<td>姓名</td>
<td>年龄</td>
</tr>
<c:forEach items="${students}" var="s" varStatus="vs">
<tr>
<td>${s.studentNo }</td>
<td>${s.studentName }</td>
<td>${s.age }</td>
</tr>
</c:forEach>
</table>
3).savesuccess.jsp
添加成功的提示信息
