概述：近年来，注解式开发越来越流行，虽然不如xml式开发更优秀，但是它的简单易上手仍然吸引大多数程序员的追捧，熟练掌握注解式开发已经称为程序员不可或缺的技能之一！  
下面将使用我最近的一个书城小项目为大家带来开发的一些必要配置:  
注：jdk1.8+web3.1

1.整体结构：

![Center][]

2.Maven的pom依赖：

<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>com.gdq</groupId> <artifactId>bookStore</artifactId> <version>1.0</version> <packaging>war</packaging> <description>基于SSH框架的网上书城</description> <dependencies>   <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>4.3.8.RELEASE</version> </dependency>   <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.3.8.RELEASE</version> </dependency>   <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>4.3.8.RELEASE</version> </dependency>   <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>5.2.10.Final</version> </dependency>   <dependency> <groupId>com.mchange</groupId> <artifactId>c3p0</artifactId> <version>0.9.5.2</version> </dependency>   <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.39</version> </dependency>   <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency>  <dependency> <groupId>taglibs</groupId> <artifactId>standard</artifactId> <version>1.1.2</version> </dependency>   <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> <scope>provided</scope> </dependency>  <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.3.8.RELEASE</version> </dependency>  <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> <scope>provided</scope> </dependency>  <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.3.3</version> </dependency>  <dependency> <groupId>net.sf.json-lib</groupId> <artifactId>json-lib</artifactId> <version>2.4</version> <classifier>jdk15</classifier> </dependency> </dependencies> <build> <plugins>  <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.6.0</version> <configuration> <source>1.8</source> <target>1.8</target> <encoding>UTF-8</encoding> </configuration> </plugin> </plugins> </build> </project>

3.web.xml

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1"> <display-name>bookStore</display-name>  <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>  <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.xml</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>springMVC</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>

4.全局配置(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: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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd 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">  <context:property-placeholder location="classpath:dbconfig.properties" /> <context:component-scan base-package="com.qf"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan>  <bean id="ds" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="${jdbc.driver}" /> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> </bean>  <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">  <property name="dataSource" ref="ds"></property>  <property name="hibernateProperties"> <props>  <prop key="hibernate.dialect">org.hibernate.dialect.MySQL57Dialect</prop>  <prop key="hibernate.show_sql">true</prop>  <prop key="hibernate.format_sql">true</prop>  <prop key="hibernate.hbm2ddl.auto">update</prop>   <prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate5.SpringSessionContext</prop> </props> </property>  <property name="packagesToScan" value="com.gdq.bean"></property> </bean>  <bean id="txManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <tx:annotation-driven transaction-manager="txManager"/> <aop:aspectj-autoproxy></aop:aspectj-autoproxy> </beans>

5.springMVC.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:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">  <context:component-scan base-package="com.gdq.web.controller"></context:component-scan>  <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">    <property name="suffix" value=".jsp"></property> </bean> </beans>

6.deconfig.properties（数据库配置）

jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/gdq?characterEncoding=UTF-8 jdbc.username=root jdbc.password=123456

7.bean层实现

package com.gdq.bean; import java.util.Date; import java.util.Set; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.FetchType; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; import javax.persistence.OneToMany; import javax.persistence.OneToOne; import javax.persistence.Table; import org.springframework.format.annotation.DateTimeFormat; @Entity @Table(name = "tb_user") public class User { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private long id; @Column(length = 20) private String username;// 用户名 private String password;// 密码 @Column(length = 2) private String gender;// 性别 @Column(length = 100) private String email;// 邮箱 @Column(length = 11) private String telephone;// 电话 @Column(length = 200) private String introduce;// 简介 private String activeCode;// 激活码 @Column(length = 5) private String role;// 角色 private int state;// 0代表未激活，1代表已激活，2代表注销 @DateTimeFormat(pattern="yyyy-MM-dd HH:mm:ss")//springMVC自动格式化 private Date registTime;// 注册时间 public long getId() { return id; } public void setId(long 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 getGender() { return gender; } public void setGender(String gender) { this.gender = gender; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } public String getTelephone() { return telephone; } public void setTelephone(String telephone) { this.telephone = telephone; } public String getIntroduce() { return introduce; } public void setIntroduce(String introduce) { this.introduce = introduce; } public String getActiveCode() { return activeCode; } public void setActiveCode(String activeCode) { this.activeCode = activeCode; } public String getRole() { return role; } public void setRole(String role) { this.role = role; } public int getState() { return state; } public void setState(int state) { this.state = state; } public Date getRegistTime() { return registTime; } public void setRegistTime(Date registTime) { this.registTime = registTime; } }

8.dao层实现

@Repository public class UserDaoImpl extends HibernateDaoSupport implements UserDao { @Autowired private SessionFactory factory; @PostConstruct public void injectSessionFactory() { super.setSessionFactory(factory); } public User insertUser(User user){ getHibernateTemplate().save(user); return user; }

9.service层实现

@Service @Transactional public class UserServiceImpl implements UserService{ @Autowired private UserDao userDao; public User regUser(User user) throws UserException { return userDao.insertUser(user); }

10.controller层实现

@Controller public class UserController { @Autowired private UserService userService; @RequestMapping("/RegistServlet") public String register(User user) throws UserException { if(userService.regUser(user)!=null) { //发送激活码 return "registersuccess"; }else {//失败跳转回去 return "register"; } }
