一、建立项目(SpringMVC+Spring+hibernate的maven项目)
二、创建结构
三、添加pom文件内容
-<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"> <modelVersion>4.0.0</modelVersion> <groupId>maven</groupId> <artifactId>maven</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <name/> <description/> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <!--<hibernate.version>5.2.10.Final</hibernate.version>--> <hibernate.version>4.2.5.Final</hibernate.version> <spring.version>4.3.10.RELEASE</spring.version> </properties> <dependencies> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <version>2.1</version> <scope>provided</scope> </dependency> <!-- mysql数据库驱动 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.37</version> </dependency> <!-- aspectjweaver.jar这是Spring AOP所要用到的包 --> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.7.1</version> </dependency> <!-- hibernate4 --> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>${hibernate.version}</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-entitymanager</artifactId> <version>${hibernate.version}</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-ehcache</artifactId> <version>${hibernate.version}</version> </dependency> <dependency> <groupId>org.hibernate.javax.persistence</groupId> <artifactId>hibernate-jpa-2.0-api</artifactId> <version>1.0.1.Final</version> </dependency> <!-- spring mvc --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <!-- spring3 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-expression</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> <exclusions></exclusions> </dependency> <!--jsp页面使用的jstl --> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> </dependencies> <build> <plugins> <plugin> <artifactId>maven-war-plugin</artifactId> </plugin> <plugin> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.5</source> <target>1.5</target> </configuration> </plugin> </plugins> </build></project>-
四、添加相关配置文件内容
1.web.xml
-<?xml version="1.0" encoding="UTF-8"?><web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaeehttp://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <display-name></display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <!-- spring hibernate --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-hibernate.xml,classpath:spring.xml</param-value> </context-param> <!-- openSessionInView配置 --> <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> <filter-mapping> <filter-name>openSessionInViewFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!--spring mvc 配置 --> <servlet> <servlet-name>spring-mvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring-mvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!-- encodeing --> <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> <!-- encoding filter for jsp page --> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener></web-app>-
2.spring-mvc.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:mvc="http://www.springframework.org/schema/mvc" 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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> <!-- 注解扫描包 --> <!--影响返回之后的页面跳转--> <context:component-scan base-package="com.ssh.controller" /> <!--影响页面的启动，dao和service都得添加，为什么？ 是因为Controller通过@Autowired注入了service，然后service通过@Autowired注入了Dao 所以在编译加载的时候会通过注解进行寻找相关内容，所以需要将dao和service的路径都写上 （已经测试过了，将service中通过@Autowired注入dao的注释掉，将下面的dao路径删除，编译不会出错， 但是调用相关方法就会报找不到dao的类的错误）--> <!--<context:component-scan base-package="com.ssh.dao,com.ssh.service" />--> <!-- 开启mvc注解 --> <mvc:annotation-driven /> <!--自动装配DefaultAnnotationHandlerMapping和AnnotationMethodHandlerAdapter --> <mvc:default-servlet-handler /> <!--页面相关的控制内容--> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <property name="suffix" value=".jsp" /> <!-- 视图文件类型 --> <property name="prefix" value="/WEB-INF/jsp" /> <!-- 视图文件的文件夹路径 --> </bean></beans>-
3.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/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsd"> <!-- 自动扫描dao和service包(自动注入) --> <context:component-scan base-package="com.ssh.dao,com.ssh.service" /></beans>-
4.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" xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsd"> <!-- 引入属性文件 --> <context:property-placeholder location="classpath:config.properties" /> <!-- 第二种形式加载properties配置文件 --> <!--<bean id="propertyConfigurer"--> <!--class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">--> <!--<property name="locations">--> <!--<list>--> <!--<value>classpath:config.properties</value>--> <!--</list>--> <!--</property>--> <!--</bean>--> <!-- 配置数据源 --> <bean name="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" > <property name="url" value="${jdbc_url}" /> <property name="username" value="${jdbc_username}" /> <property name="password" value="${jdbc_password}" /> <property name="driverClassName" value="${driverClassName}"/> </bean> <!-- 配置hibernate session工厂 --> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <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">${hibernate.show_sql}</prop> <prop key="hibernate.format_sql">${hibernate.format_sql}</prop> <prop key="current_session_context_class">thread</prop> </props> </property> <!-- 自动扫描注解方式配置的hibernate类文件 --> <property name="packagesToScan"> <list> <!-- 此处与entity实体路径对应 --> <value>com.ssh.entity</value> </list> </property> </bean> <!-- 配置事务管理器 --> <bean name="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 注解方式配置事物 --> <tx:annotation-driven transaction-manager="transactionManager" /></beans>-
5.config.properties
-#\u5C5E\u6027\u6587\u4EF6#Oracle \u7684\u914D\u7F6E#hibernate.dialect=org.hibernate.dialect.OracleDialect#driverClassName=oracle.jdbc.driver.OracleDriver#validationQuery=SELECT 1 FROM DUAL#jdbc_url=jdbc:oracle:thin:@localhost:1521:orcl#jdbc_username=#jdbc_password=#SQLServer \u7684\u914D\u7F6E#hibernate.dialect=org.hibernate.dialect.SQLServerDialect#driverClassName=net.sourceforge.jtds.jdbc.Driver#validationQuery=SELECT 1#jdbc_url=jdbc:jtds:sqlserver://127.0.0.1:1433/sy#jdbc_username=#jdbc_password=#Derby \u7684\u914D\u7F6E#hibernate.dialect=org.hibernate.dialect.DerbyDialect#driverClassName=org.apache.derby.jdbc.EmbeddedDriver#validationQuery=SELECT 1#jdbc_url=jdbc:derby:sy;create=true#jdbc_username=#jdbc_password=#MySQL \u7684\u914D\u7F6E#hibernate.dialect=org.hibernate.dialect.MySQLDialecthibernate_dialect=org.hibernate.dialect.MySQLDialect#hibernate_dialect=org.hibernate.dialect.MySQLMyISAMDialectdriverClassName=com.mysql.jdbc.DrivervalidationQuery=SELECT 1jdbc_url=jdbc:mysql://localhost:3306/sshtext?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNulljdbc_username=rootjdbc_password=roothibernate.hbm2ddl.auto=updatehibernate.show_sql=truehibernate.format_sql=falsesessionInfoName=sessionInfouploadFieldName=filedatauploadFileMaxSize=20971520uploadFileExts=txt,rar,zip,doc,docx,xls,xlsx,jpg,jpeg,gif,png,swf,wmv,avi,wma,mp3,miduploadDirectory=attached-五、添加相关类
1.entity
-package com.ssh.entity;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.Id;/** * Created by mk on 2017/8/5. */@Entity(name="t_user")public class UserEntity { @Id @GeneratedValue private int id; private String name; private String password; public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; }}-
2.Dao
-package com.ssh.dao;import com.ssh.entity.UserEntity;/** * Created by mk on 2017/8/5. */public interface UserDao { public int insert(UserEntity userEntity);}-
3.DaoImpl
-package com.ssh.dao.impl;import com.ssh.dao.UserDao;import com.ssh.entity.UserEntity;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Repository;/** * Created by mk on 2017/8/5. */@Repositorypublic class UserDaoImpl implements UserDao { @Autowired SessionFactory sessionFactory; public int insert(UserEntity userEntity) { Session session = sessionFactory.getCurrentSession(); return (Integer)session.save(userEntity); }}-
4.Service
-package com.ssh.service;import com.ssh.entity.UserEntity;/** * Created by mk on 2017/8/5. */public interface UserService { public int insert(UserEntity userEntity);}-
5.ServiceImpl
-package com.ssh.service.impl;import com.ssh.dao.UserDao;import com.ssh.entity.UserEntity;import com.ssh.service.UserService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;/** * Created by mk on 2017/8/5. */@Servicepublic class UserServiceImpl implements UserService { @Autowired UserDao userDao; public int insert(UserEntity userEntity) { return userDao.insert(userEntity); }}-
6.Controller
-package com.ssh.controller;import com.ssh.entity.UserEntity;import com.ssh.service.UserService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;/** * Created by mk on 2017/8/5. */@RequestMapping("/user1")@Controllerpublic class userController { @Autowired UserService userService; @RequestMapping("/testindex") public String inset(Model model){ UserEntity userEntity = new UserEntity(); userEntity.setName("1"); userEntity.setPassword("123"); int result = userService.insert(userEntity); model.addAttribute("result",result); return "/test"; }}-
外.text.jsp
-<%-- Created by IntelliJ IDEA. User: mk Date: 2017/8/5 Time: 17:53 To change this template use File | Settings | File Templates.--%><%@ page contentType="text/html;charset=UTF-8" language="java" %><html><head> <title>Title</title></head><body> ${result}<br></body></html>-六、建立数据库相关内容
1.建立数据库
2.建立表（和entity中的字段类型对应）
-CREATE TABLE `t_user` ( `id` int(100) NOT NULL AUTO_INCREMENT, `name` varchar(255) DEFAULT NULL, `password` varchar(255) DEFAULT NULL, PRIMARY KEY (`id`)) ENGINE=InnoDB AUTO_INCREMENT=18 DEFAULT CHARSET=utf8;-七、配置tomcat
