1. 开发环境 IDEA
2. 在pom.xml中配置引用相关的包。
<properties> <junit.version>4.10</junit.version> <log4j.version>2.0</log4j.version> <mysql.jdbc.version>5.1.21</mysql.jdbc.version> <hibernate.version>4.3.5.Final</hibernate.version> <commons.fileupload.version>1.2.1</commons.fileupload.version> <javassist.version>3.12.1.GA</javassist.version> <cxf.version>3.0.2</cxf.version> <spring.version>4.1.3.RELEASE</spring.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <!-- cxf --> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-core</artifactId> <version>${cxf.version}</version> </dependency> <!-- 读取字节码包 --> <dependency> <groupId>javassist</groupId> <artifactId>javassist</artifactId> <version>${javassist.version}</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> <scope>provided</scope> </dependency> <!-- commons配置 --> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>${commons.fileupload.version}</version> </dependency> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>1.4</version> </dependency> <!-- log4j的依赖 --> <dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-api</artifactId> <version>${log4j.version}</version> </dependency> <dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-core</artifactId> <version>${log4j.version}</version> </dependency> <!-- mysql的依赖 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>${mysql.jdbc.version}</version> </dependency> <!-- hibernate部分 --> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>${hibernate.version}</version> </dependency> <!-- c3p0 --> <dependency> <groupId>c3p0</groupId> <artifactId>c3p0</artifactId> <version>0.9.1.2</version> </dependency> <!-- spring --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-hibernate3</artifactId> <version>2.0.8</version> </dependency> <!-- aspectj --> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjrt</artifactId> <version>1.8.4</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.8.4</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjlib</artifactId> <version>1.6.2</version> </dependency> <!-- quartz --> <dependency> <groupId>org.quartz-scheduler</groupId> <artifactId>quartz</artifactId> <version>2.2.0</version> </dependency> <dependency> <groupId>org.apache.velocity</groupId> <artifactId>velocity</artifactId> <version>1.6</version> </dependency> <dependency> <groupId>org.apache.velocity</groupId> <artifactId>velocity-tools</artifactId> <version>1.3</version> </dependency> </dependencies> <build> <finalName>hibernatedemo</finalName> <plugins> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>tomcat-maven-plugin</artifactId> <version>1.1</version> <configuration> <path>/hibernatedemo</path> <port>8080</port> <uriEncoding>UTF-8</uriEncoding> <url>http://localhost:8080/hibernatedemo/index</url> <server>tomcat6</server> </configuration> </plugin> </plugins> </build>
3. 创建Java 代码结构如下：
TestController:
@Autowired private UsersDAO usersDAO; @RequestMapping(value = "/index", method = RequestMethod.GET) public ModelAndView indexGet(){ List<Users> list = usersDAO.getAllUser(); ModelAndView mv = new ModelAndView("index") ; mv.addObject("size", list.size()); return mv; } @RequestMapping(value = "/", method = RequestMethod.GET) @ResponseBody public String defaultGet(){ return "default" ; }
UsersDAO
public class UsersDAO { private SessionFactory sessionFactory; public void setSessionFactory(SessionFactory sessionFactory) { this.sessionFactory = sessionFactory; } public SessionFactory getSessionFactory() { return sessionFactory; } public List<Users> getAllUser(){ String hsql="from Users"; Session session = sessionFactory.openSession(); Query query = session.createQuery(hsql); return query.list(); } }
Users
@Entity() //@Table(name="users") public class Users { public Users(){ } @Id @GeneratedValue public Long id ; public String name; public String email; public String password; public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } }
4. 配置Spring 和 Hibernate4 Xml 设置，文件放在代码目录中的resources文件夹中
spring-hibernate.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" 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-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd "> <!-- Hibernate4 --> <!-- 加载资源文件 其中包含变量信息，必须在Spring配置文件的最前面加载，即第一个加载--> <context:property-placeholder location="classpath:persistence-mysql.properties" /> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="packagesToScan"> <list> <!-- 可以加多个包 --> <value>priv.bruce.demoproject.hibernatedemo.model</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop> <prop key="hibernate.dialect">${hibernate.dialect}</prop> <prop key="hibernate.show_sql">${hibernate.show_sql}</prop> <!-- <prop key="hibernate.current_session_context_class">thread</prop> --> </props> </property> </bean> <!-- 数据库映射 --> <!-- class="org.apache.tomcat.dbcp.dbcp.BasicDataSource" --> <!-- class="org.springframework.jdbc.datasource.DriverManagerDataSource" --> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="${jdbc.driverClassName}" /> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.user}" /> <property name="password" value="${jdbc.pass}" /> </bean> <!-- 配置Hibernate事务管理器 --> <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <!-- 配置事务异常封装 --> <bean id="persistenceExceptionTranslationPostProcessor" class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" /> <!-- 声明式容器事务管理 ,transaction-manager指定事务管理器为transactionManager --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="add*" propagation="REQUIRED" /> <tx:method name="get*" propagation="REQUIRED" /> <tx:method name="*" read-only="true" /> </tx:attributes> </tx:advice> <!--<aop:config expose-proxy="true">--> <!--<!– 只对业务逻辑层实施事务 –>--> <!--<aop:pointcut id="txPointcut" expression="execution(* com.lei.demo.service..*.*(..))" />--> <!--<!– Advisor定义，切入点和通知分别为txPointcut、txAdvice –>--> <!--<aop:advisor pointcut-ref="txPointcut" advice-ref="txAdvice"/>--> <!--</aop:config>--> <bean id="usersDAO" class="priv.bruce.demoproject.hibernatedemo.dao.UsersDAO"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> </beans>
系统参数配置文件 persistence-mysql.properties
# jdbc.X jdbc.driverClassName=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://datasource?useUnicode=true&characterEncoding=utf8 jdbc.user=root jdbc.pass=123456 # hibernate.X hibernate.connection.driverClass=org.gjt.mm.mysql.Driver hibernate.connection.url=jdbc:mysql://datasource?useUnicode=true&characterEncoding=utf8 hibernate.dialect=org.hibernate.dialect.MySQL5Dialect hibernate.connection.username=root hibernate.connection.password=pass hibernate.show_sql=true hibernate.hbm2ddl.auto=create-drop
5. Spring Mvc 配置
5.1 webapp中增加view 用做保存 velocity模版
5.2 配置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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>Archetype Created Web Application</display-name> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:/spring-*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 定义DispatcherServlet --> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <!-- 默认/WEB-INF/[servlet名字]-servlet.xml加载上下文， 如果配置了contextConfigLocation参数， 将使用classpath:/lei-dispatcher-servlet.xml加载上下文 --> <param-name>contextConfigLocation</param-name> <param-value>classpath:/dispatcher-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <!-- 拦截匹配的请求，这里所有请求采用名字为lei-dispatcher的DispatcherServlet处理 --> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
5.3 配置 dispatcher-servlet.xml， 文件放在resources文件夹中，也可以自行配置文件所在位置。
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:p="http://www.springframework.org/schema/p" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 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/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd "> <!-- 启动自动扫描该包下所有的Bean(例如@Controller) --> <context:component-scan base-package="priv.bruce.demoproject.hibernatedemo.controller" /> <!-- velocity解析器,替换掉原来的jsp --> <bean id="viewResolver" class="org.springframework.web.servlet.view.velocity.VelocityViewResolver"> <property name="contentType" value="text/html;charset=UTF-8" /> <property name="suffix" value=".html" /> </bean> <bean id="velocityConfig" class="org.springframework.web.servlet.view.velocity.VelocityConfigurer"> <property name="resourceLoaderPath"> <value>WEB-INF/views/</value> </property> <property name="velocityProperties"> <props> <prop key="input.encoding">UTF-8</prop> <prop key="output.encoding">UTF-8</prop> <prop key="contentType">text/html;charset=UTF-8</prop> </props> </property> </bean> </beans>
5.4 创建 模板 index.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> size: $!size </body> </html>
6. 创建数据表，插入一条记录。
CREATE TABLE `users` ( `id` bigint(20) NOT NULL AUTO_INCREMENT, `email` varchar(255) DEFAULT NULL, `name` varchar(255) DEFAULT NULL, `password` varchar(255) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=latin1;
7. 启动项目输入地址： http://127.0.0.1:8080/hibernatedemo/index
显示：size: 1
表示项目已经运行成功
