Spring+SpringMVC+Hibernate入門案例
阿新 • • 發佈：2018-12-07
在這裡實現Spring+SpringMVC+Hibernate的一個小Demo，內容包含一些增刪改查。
pom.xml先奉上：
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" 一：連線資料庫，因為使用的是Hibernate，所以需要寫一些資料庫相關的配置資訊，新建config,properties.xml，將你的資料庫相關的配置資訊填寫好。
## 引入Spring配置 application configs##
#jdbc c3p0 config##
jdbc.driver = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://這裡寫的是伺服器地址:3306/這裡是資料庫名稱?useUnicode=true&characterEncoding=utf-8
jdbc.username = root
jdbc.password = root
#hibernate config##
hibernate.dialect = org.hibernate.dialect.MySQLDialect
hibernate.show_sql = true
hibernate.format_sql = false
hibernate.hbm2ddl.auto = update
hibernate.cache.use_second_level_cache = true
hibernate.cache.use_query_cache = true
hibernate.cache.region.factory_class = org.hibernate.cache.ehcache.EhCacheRegionFactory
hibernate.cache.provider_configuration_file_resource_path = ehcache.xml二：Hibernate是包含一級和二級快取，一級快取是預設開啟的，二級快取就需要手動開啟，所以這裡也把快取的配置寫上去，建立一個名為ehcache.xml檔案，配置快取資訊。
<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../config/ehcache.xsd">
<diskStore path="D:/ehcache" />
<!-- DefaultCache setting. -->
<defaultCache
maxElementsInMemory="1000"
eternal="false"
timeToIdleSeconds="120"
timeToLiveSeconds="120"
maxElementsOnDisk="1000000"
overflowToDisk="true"
memoryStoreEvictionPolicy="LRU">
</defaultCache>
<!-- Special objects setting. -->
<cache
name="org.andy.work.entity.AcctUser"
maxElementsInMemory="2"
memoryStoreEvictionPolicy="LRU"
eternal="true"
diskPersistent="false"
overflowToDisk="false"
maxElementsOnDisk="1000000" />
</ehcache>三：書寫Hibernate的配置檔案，建立一個名為spring-hibernate.xml的xml檔案，配置一些bean實體（很重要）
<?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:tx="http://www.springframework.org/schema/tx"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-4.1.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-4.1.xsd">
<!-- 配置資料來源 c3p0 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
destroy-method="close">
<property name="driverClass" value="${jdbc.driver}" />
<property name="jdbcUrl" value="${jdbc.url}" />
<property name="user" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<!-- 請求超時時間 -->
<property name="checkoutTimeout" value="30000" />
<!-- 每60秒檢查所有連線池中的空閒連線。預設值: 0，不檢查 -->
<property name="idleConnectionTestPeriod" value="30" />
<!-- 連線資料庫連線池最大空閒時間 -->
<property name="maxIdleTime" value="30" />
<!-- 連線池初始化連線數 -->
<property name="initialPoolSize" value="5" />
<property name="minPoolSize" value="5" />
<property name="maxPoolSize" value="20" />
<!--當連線池中的連線耗盡的時候c3p0一次同時獲取的連線數。預設值: 3 -->
<property name="acquireIncrement" value="5" />
</bean>
<!-- 配置過濾器-->
<bean name="myInterceptior" class="org.liang.work.filter.MyInterceptor"/>
<!-- 配置hibernate的SessionFactory -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<!-- 注入資料來源 相關資訊看原始碼 -->
<property name="dataSource" ref="dataSource" />
<!-- 配置過濾器 -->
<property name="entityInterceptor" ref="myInterceptior"></property>
<!-- hibernate配置資訊 -->
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">${hibernate.dialect}</prop>
<prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
<prop key="hibernate.format_sql">${hibernate.format_sql}</prop>
<prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>
<!--開啟二級快取 ehcache-->

<prop key="hibernate.cache.provider_configuration_file_resource_path">${hibernate.cache.provider_configuration_file_resource_path}</prop>
</props>
</property>
<!-- 掃描hibernate註解配置的entity -->
<property name="packagesToScan" value="org.liang.work.entity" />
</bean>
<!-- 配置事務管理器 -->
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<!-- 配置事務增強處理Bean，指定事務管理器 -->
<tx:advice id="transactionAdvice" transaction-manager="transactionManager">
<!-- 配置詳細事務處理語義 -->
<tx:attributes>
<tx:method name="insert*" propagation="REQUIRED" />
<tx:method name="update*" propagation="REQUIRED" />
<tx:method name="delete*" propagation="REQUIRED" />
<tx:method name="get*" propagation="SUPPORTS" read-only="true" />
<tx:method name="find*" propagation="SUPPORTS" read-only="true" />
<tx:method name="select*" propagation="SUPPORTS" read-only="true" />
<tx:method name="load*" propagation="SUPPORTS" read-only="true" />
<!-- 其他採用預設事務方式 -->
<tx:method name="*" />
</tx:attributes>
</tx:advice>
<!-- Spring aop事務管理 -->
<aop:config>
<!-- <!– 配置切入點 –>-->
<aop:pointcut id="transactionPointcut"
expression="execution(* org.liang.work.service..*Impl.*(..))" />
<!--<!– 指定在txAdvice切入點應用txAdvice事務增強處理 –>-->
<aop:advisor pointcut-ref="transactionPointcut"
advice-ref="transactionAdvice" />
</aop:config>
</beans>四：編寫spring-mvc.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:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p" 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
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">
<!-- 自動掃描@Controller注入為bean -->
<context:component-scan base-package="org.liang.work.controller" />
<!-- 以下為SpringMVC配置 -->
<mvc:annotation-driven>
<!-- 返回json資料，@response使用 -->
<mvc:message-converters register-defaults="true">
<bean
class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/html;charset=UTF-8</value>
<value>application/json;charset=UTF-8</value>
</list>
</property>
</bean>
</mvc:message-converters>
</mvc:annotation-driven>
<!-- 對模型檢視名稱的解析，即在模型檢視名稱新增前後綴 -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/views" />
<property name="suffix" value=".jsp" />
</bean>
</beans>五：編寫spring.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">
<!-- 載入配置檔案 -->
<context:property-placeholder location="classpath:config.properties"/>
<!-- 掃描service自動注入為bean -->
<context:component-scan base-package="org.liang.work.service,org.liang.work.dao,org.liang.work.service.impl,org.liang.work.dao.impl" />
</beans>六：編寫web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="WebApp_ID" version="2.5">
<display-name>springmvc_demo</display-name>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring.xml,classpath:spring-hibernate.xml</param-value>
</context-param>
<filter>
<filter-name>encodingFilter</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>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- openSessionInView配置 作用是延遲session關閉到view層 -->
<filter>
<filter-name>openSessionInViewFilter</filter-name>
<filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
<init-param>
<param-name>singleSession</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<!-- 監聽servletContext，啟動contextConfigLocation中的spring配置資訊 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 防止spring記憶體溢位監聽器 -->
<listener>
<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
</listener>
<servlet>
<description>spring mvc servlet</description>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<!-- 此處配置的是SpringMVC的配置檔案 -->
<param-value>classpath:spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<filter-mapping>
<filter-name>openSessionInViewFilter</filter-name>
<url-pattern>*.htmls</url-pattern>
</filter-mapping>
<!-- 配置session超時時間，單位分鐘 -->
<session-config>
<session-timeout>30</session-timeout>
</session-config>
<welcome-file-list>
<welcome-file>/index.html</welcome-file>
</welcome-file-list>
</web-app>以上，框架的各種配置檔案基本搭建完成，我這裡省略了日誌配置檔案。接下來就是程式碼的編寫：
結構如下圖中;
重點內容
我這裡直接貼上各層程式碼,介面層的就不貼了，直接貼他的實現類：
1，controller
package org.liang.work.controller;
import org.apache.log4j.Logger;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.jboss.logging.annotations.Param;
import org.liang.work.dto.ResponseWrapper;
import org.liang.work.entity.AcctUser;
import org.liang.work.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import java.util.Date;
import java.util.List;
import java.util.UUID;
