笔记48 Spring+SpringMVC+Hibernate整合
2024-09-06 06:33:08
搭建Spring+SpringMVC+Hibernate的框架的思路如下：
1、创建Maven项目，按需映入Maven包依赖。
2、搭建Spring：配置Spring对控件层Bean的注入。
3、搭建Hibernate：配置数据源，配置SessionFactory，配置事务。
4、映入SpringMVC：配置SpringMVC配置信息。
5、配置web.xml容器
6、测试三个框架的整合：。
一、创建Maven项目、导入依赖

二、配置web.xml
1.配置Spring的IOC容器
<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>
在src/main/resources下新建文件config，将所有的配置文件放在里面。创建spring配置文件applicationContext.xml
2.配置SpringMVC的核心控制器
<servlet>
<servlet-name>dispatcherServlet</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>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
在config目录中创建SpringMVC的配置文件springmvc.xml
3.配置编码方式（过滤器），这个过滤器必须放在所有过滤器前。
<filter>
<filter-name>characterEncodingFilter</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>
</filter>
<filter-mapping>
<filter-name>characterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
4.为了使用SpringMVC框架实现REST，需配置HiddenHttpMethodFilter。
<filter>
<filter-name>hiddenHttpMethodFilter</filter-name>
<filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>hiddenHttpMethodFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
web.xml
<?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" id="WebApp_1529217958650">
<!-- 配置Spring IOC 容器 -->
<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> <!-- 配置Springmvc的核心控制器 -->
<servlet>
<servlet-name>dispatcherServlet</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>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
<!-- 配置编码方式过滤器，且必须配置在所有的过滤器最前面 -->
<filter>
<filter-name>characterEncodingFilter</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>
</filter>
<filter-mapping>
<filter-name>characterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 为了使用SpringMVC框架实现REST，需配置HiddenHttpMethodFilter -->
<filter>
<filter-name>hiddenHttpMethodFilter</filter-name>
<filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>hiddenHttpMethodFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping> </web-app>
三、配置SpringMVC
1.配置自动扫描的包
<context:component-scan base-package="com.Spittr.dao.impl"
use-default-filters="false">
<context:include-filter type="annotation"
expression="org.springframework.stereotype.Controller" />
<context:include-filter type="annotation"
expression="org.springframework.web.bind.annotation.ControllerAdvice" />
</context:component-scan>
2.配置视图解析器
应用中所有的视图即JSP文件都放入WEB-INF下的view文件夹中。
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/view/">
</property>
<property name="suffix" value=".jsp">
</property>
</bean>
3.配置静态资源
<mvc:default-servlet-handler/>
4.配置注解
<mvc:annotation-driven></mvc:annotation-driven>
springmvc.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:mvc="http://www.springframework.org/schema/mvc" 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-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
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> <!-- 配置自动扫描的包 -->
<context:component-scan base-package="com.Spittr.dao.impl"
use-default-filters="false">
<context:include-filter type="annotation"
expression="org.springframework.stereotype.Controller" />
<context:include-filter type="annotation"
expression="org.springframework.web.bind.annotation.ControllerAdvice" />
</context:component-scan> <!-- 配置视图解析器 -->
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/view/">
</property>
<property name="suffix" value=".jsp">
</property>
</bean>
<!-- 配置静态资源 -->
<mvc:default-servlet-handler/>
<!-- 配置注解 -->
<mvc:annotation-driven></mvc:annotation-driven>
</beans>
四、配置Spring
1.配置自动扫描的包
包含Controller和ControllerAdvice注解的bean交给SpringMVC来扫描，Spring就不再扫描了，所以要把这两个注解排除在外。
<context:component-scan base-package="com.Spittr"
use-default-filters="false">
<!-- 去除由Springmvc负责扫描的注解 -->
<context:exclude-filter type="annotation"
expression="org.springframework.stereotype.Controller" />
<context:exclude-filter type="annotation"
expression="org.springframework.web.bind.annotation.ControllerAdvice" />
</context:component-scan>
2.配置数据源
数据源配置文件：db.properties,也放在config文件夹中。
jdbc.user=root
jdbc.password=123456
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.jdbcUrl=jdbc\:mysql\://localhost\:3306/spittr
<context:property-placeholder location="classpath:/config/db.properties" />
3.配置DataSource，使用c3p0连接池。
<bean class="com.mchange.v2.c3p0.ComboPooledDataSource" id="dataSource">
<property name="user" value="${jdbc.user}"></property>
<property name="password" value="${jdbc.password}"></property>
<property name="driverClass" value="${jdbc.driverClass}"></property>
<property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property>
</bean>
五、配置Hibernate
1.配置SeeionFactory
<bean class="org.springframework.orm.hibernate5.LocalSessionFactoryBean"
id="sessionFactory"> </bean>
在SessionFactory中需要添加以下三个property：
1.1.配置数据源
<property name="dataSource" ref="dataSource"></property>
1.2.配置实体包（pojo）
<property name="PhysicalNamingStrategy">
<bean class="org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl"></bean>
</property>
<property name="packagesToScan" value="com.Spittr.entity"></property>
1.3.配置Hibernate的常用属性
<property name="hibernateProperties">
<props>
<!-- 数据库的方言 -->
<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.hbm2ddl.auto">update</prop>
</props>
</property>
2.配置hibernate的事务管理器
<bean class="org.springframework.orm.hibernate5.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
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"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.1.xsd"> <!-- 配置自动扫描的包 -->
<context:component-scan base-package="com.Spittr"
use-default-filters="false">
<!-- 去除由Springmvc负责扫描的注解 -->
<context:exclude-filter type="annotation"
expression="org.springframework.stereotype.Controller" />
<context:exclude-filter type="annotation"
expression="org.springframework.web.bind.annotation.ControllerAdvice" />
</context:component-scan> <!-- 配置数据源 -->
<context:property-placeholder location="classpath:/config/db.properties" /> <!-- 配置DataSource -->
<bean class="com.mchange.v2.c3p0.ComboPooledDataSource" id="dataSource">
<property name="user" value="${jdbc.user}"></property>
<property name="password" value="${jdbc.password}"></property>
<property name="driverClass" value="${jdbc.driverClass}"></property>
<property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property>
</bean> <!-- 配置SeeionFactory -->
<bean class="org.springframework.orm.hibernate5.LocalSessionFactoryBean"
id="sessionFactory">
<!-- 配置数据源 -->
<property name="dataSource" ref="dataSource"></property>
<!-- 配置实体包（pojo） -->
<property name="PhysicalNamingStrategy">
<bean
class="org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl"></bean>
</property>
<property name="packagesToScan" value="com.Spittr.entity"></property> <!-- 配置Hibernate的常用属性 -->
<property name="hibernateProperties">
<props>
<!-- 数据库的方言 -->
<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.hbm2ddl.auto">update</prop>
</props>
</property>
</bean> <!-- 配置hibernate的事务管理器 -->
<bean class="org.springframework.orm.hibernate5.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
</beans>
六、测试
1.测试是否能得到配置文件applicationContext.xml
private ApplicationContext ctx = null;
ctx = new ClassPathXmlApplicationContext("/config/applicationContext.xml");
System.out.println(ctx);
2.测试是否能获取数据源
DataSource dataSource = ctx.getBean(DataSource.class);
System.out.println(dataSource.getConnection().toString());
3.测试Hibernate中SessionFactory是否能获取
SessionFactory sessionFactory = ctx.getBean(SessionFactory.class);
System.out.println(sessionFactory);
4.对数据库进行操作
首先创建实体类：Spitter.java
package com.Spittr.entity; import java.io.Serializable; import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table; @Entity
@Table(name = "spitter")
public class Spitter implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
int id;
String username;
String password;
String email; public Spitter() {
// TODO Auto-generated constructor stub
} public Spitter(String username, String password, String email) {
super();
this.username = username;
this.password = password;
this.email = email;
} public int getId() {
return id;
} public void setId(int 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;
} public String getEmail() {
return email;
} public void setEmail(String email) {
this.email = email;
}
}
测试
Session session = sessionFactory.openSession();
Transaction transaction = session.beginTransaction();
Spitter spitter = new Spitter("222qqqq222", "123123", "123213");
session.save(spitter);
transaction.commit();
session.close();
testSSH.java
package com.Spittr.test; import java.sql.SQLException; import javax.sql.DataSource;
import javax.transaction.HeuristicMixedException;
import javax.transaction.HeuristicRollbackException;
import javax.transaction.RollbackException;
import javax.transaction.SystemException; import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext; import com.Spittr.entity.Spitter; public class testSSH { private ApplicationContext ctx = null; @Test
public void testDataSource() throws SQLException, SecurityException, RollbackException, HeuristicMixedException,
HeuristicRollbackException, SystemException { ctx = new ClassPathXmlApplicationContext("/config/applicationContext.xml");
System.out.println(ctx);
// System.out.println();
// 测试数据源
DataSource dataSource = ctx.getBean(DataSource.class);
System.out.println(dataSource.getConnection().toString()); // 测试SessionFactory
SessionFactory sessionFactory = ctx.getBean(SessionFactory.class);
System.out.println(sessionFactory); // 测试操作数据库表(session)
Session session = sessionFactory.openSession();
Transaction transaction = session.beginTransaction();
Spitter spitter = new Spitter("222qqqq222", "123123", "123213");
session.save(spitter);
transaction.commit();
session.close(); } }
七、配置过程中遇到的问题
1.classpath的相关问题
| 前缀 | 说明 |
|---|---|
| classpath | 优先本项目class路径查找，没有的话依次在其他jar包中class路径查找，找到第一个匹配的为止 |
| classpath* | 加载到所有class路径下的配置文件，包括jar包的class路径下，最终加载所有匹配的 |
| file | 通过URL加载，来源为文件系统（注意文件读取权限） |
| http | 通过URL加载，来源为网络 |
在maven项目中，classpath对应的目录是Webapp\target\classes，也就是把配置文件都放入src/main/resources目录下即可，本例中是把config文件夹放入src/main/resources中，所以在读取config中的配置文件时，所以才会使用classpath:/config/***形式。
2.hibernate的配置
org.hibernate.cfg.NamingStrategy接口允许你为数据库中的对象和schema 元素指定一个“命名标准”. 你可能会提供一些通过Java标识生成数据库标识或将映射定义文件中"逻辑"表/列名处理成"物理"表/列名的规则. 这个特性有助于减少冗长的映射定义文件。
但是在Hibernate到5.1的后，hibernate.ejb.naming_strategy将不再被支持，而是被替换成了两个属性：
- hibernate.physical_naming_strategy：隐式命名策略，使用此属性当我们使用的表或列没有明确指定一个使用的名称。
- hibernate.implicit_naming_strategy：物理命名策略，用于转换“逻辑名称”(隐式或显式)的表或列成一个物理名称。
①对于physical_naming_strategy有两个常用的配置：
- org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy
- org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
对于PhysicalNamingStrategyStandardImpl有DefaultNamingStrategy的效果；对于SpringPhysicalNamingStrategy有
ImprovedNamingStrategy的效果。
②在sessionFactory的bean里配置。
<property name="PhysicalNamingStrategy">
<bean class="org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl"></bean>
</property>
或
<property name="ImplicitNamingStrategy">
<bean class="org.hibernate.boot.model.naming.ImplicitNamingStrategyLegacyHbmImpl" />
</property>
