一、引入lib包
pom.xml，引入需要的jar包
<?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

二、编写配置文件
编写Spring的配置文件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:aop="http://www.springframework.org/schema/aop" xmlns:p="http://www.springframework.org/schema/p" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd"> <!-- 扫描注解，注册bean --> <context:component-scan base-package="com.kszsa"> <!-- 跳过@Controller --> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> </beans>
springMVC的配置文件 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" xmlns:aop="http://www.springframework.org/schema/aop" 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-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd"> <!-- mvc注解 --> <mvc:annotation-driven/> <!-- 扫描 --> <context:component-scan base-package="com.kszsa" use-default-filters="false"> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <!-- 视图解析 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/"></property> <property name="suffix" value=".jsp"></property> </bean> <!-- 解析静态资源 --> <mvc:default-servlet-handler/> </beans>
数据库连接信息配置文件config.properties
#database connection config jdbc.driver = com.mysql.jdbc.Driver jdbc.url = jdbc:mysql://127.0.0.1:3306/xcjgk?useUnicode=true&characterEncoding=utf-8 jdbc.username = root jdbc.password = root diver_name=com.mysql.jdbc.Driver validationQuery.sql=SELECT 1 #hibernate config hibernate.dialect = org.hibernate.dialect.MySQLDialect hibernate.show_sql = true hibernate.format_sql = true hibernate.hbm2ddl.auto =update
hibernate配置文件 spring-hibernate.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:aop="http://www.springframework.org/schema/aop" xmlns:util="http://www.springframework.org/schema/util" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:task="http://www.springframework.org/schema/task" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-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/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd" default-autowire="byName" default-lazy-init="false"> <!-- hibernate --> <!-- 扫描properties配置文件 --> <context:property-placeholder location="classpath:config.properties"/> <!-- 配置数据源1 --> <bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"> <property name="url" value="$jdbc.url" /> <property name="username" value="$jdbc.username" /> <property name="password" value="$jdbc.password" /> <!-- 初始化连接大小 --> <property name="initialSize" value="0" /> <!-- 连接池最大使用连接数量 --> <property name="maxActive" value="50" /> <!-- 连接池最小空闲 --> <property name="minIdle" value="5" /> <!-- 获取连接最大等待时间 --> <property name="maxWait" value="60000" /> <!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 --> <property name="timeBetweenEvictionRunsMillis" value="60000" /> <!-- 配置一个连接在池中最小生存的时间，单位是毫秒 --> <property name="minEvictableIdleTimeMillis" value="300000" /> <property name="validationQuery" value="$validationQuery.sql" /> <property name="testOnBorrow" value="false" /> <property name="testOnReturn" value="false" /> <property name="testWhileIdle" value="true" /> <!-- 开启Druid的监控统计功能 --> <property name="filters" value="stat" /> <!-- 打开removeAbandoned功能 --> <property name="removeAbandoned" value="true" /> <!-- 1800秒，也就是30分钟 --> <property name="removeAbandonedTimeout" value="3600" /> <!-- 关闭abanded连接时输出错误日志 --> <property name="logAbandoned" value="true" /> <!-- Oracle连接是获取字段注释 --> <property name="connectProperties"> <props> <prop key="remarksReporting">true</prop> </props> </property> </bean> <!-- session工厂 --> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource"></property> <property name="packagesToScan" value="com.kszsa"></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">$hibernate.show_sql</prop> <prop key="hibernate.format_sql">$hibernate.format_sql</prop> </props> </property> </bean> <!-- 事务管理器 --> <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 开启事务注解 --> <tx:annotation-driven transaction-manager="transactionManager"/> </beans>
编写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_3_0.xsd" version="3.0"> <display-name>ssht</display-name> <!-- 乱码的处理 --> <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> <!-- spring start --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml,classpath*:spring-*.xml</param-value> <!-- <param-value>classpath:applicationContext.xml</param-value>--> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- spring end --> <!-- spring mvc start --> <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> <!-- spring mvc end --> </web-app>
至此配置文件编写完成
三、编写bean
编写User.java
package com.kszsa.user; import javax.persistence.*; @Entity @Table(name="user") public class User @Id @Column(name="id") @GeneratedValue(strategy=GenerationType.IDENTITY) private Integer id; @Column(name="name") private String name; @Column(name="description") private String description; public Integer getId() return id; public void setId(Integer id) this.id = id; public String getName() return name; public void setName(String name) this.name = name; public String getDescription() return description; public void setDescription(String description) this.description = description;
四、编写 DAO
编写通用接口ICommonDao.java
package com.kszsa.common.dao; import java.io.Serializable; import java.util.List; public interface ICommonDao<T,PK extends Serializable> T load(PK id); T get(PK id); List<T> findAll(); void persist(T entity); void add(T entity); void update(T entity); void delete(PK id); void flush();
编写UserDao.java
package com.kszsa.user.dao; import com.kszsa.common.dao.ICommonDao; import com.kszsa.user.User; public interface UserDao extends ICommonDao<User, Integer>
编写UserDao实现类 UserDaoImp.java
package com.kszsa.user.dao; import com.kszsa.user.User; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Repository; import java.util.List; @Repository public class UserDaoImp implements UserDao @Autowired private SessionFactory sessionFactory; private Session getSession() return this.sessionFactory.getCurrentSession(); @Override public User load(Integer id) return (User)this.getSession().load(User.class,id); @Override public User get(Integer id) return (User) this.getSession().get(User.class, id); @Override public List<User> findAll() return this.getSession().createQuery("from User").list(); @Override public void persist(User entity) this.getSession().persist(entity); @Override public void add(User entity) this.getSession().save(entity); @Override public void update(User entity) this.getSession().update(entity); @Override public void delete(Integer id) User user = this.get(id); try this.getSession().delete(user); catch(Exception e) e.printStackTrace(); @Override public void flush() this.getSession().flush();
五、编写service层
编写UserService.java
package com.kszsa.user.service; import com.kszsa.user.User; import com.kszsa.user.dao.UserDaoImp; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import org.springframework.transaction.annotation.Transactional; import java.util.List; @Transactional @Service public class UserService public void show() System.out.println("userService is called..."); @Autowired private UserDaoImp userDaoImp; public User getById(Integer id) return this.userDaoImp.get(id); public List<User> findAll() return this.userDaoImp.findAll(); public void add(User user) this.userDaoImp.add(user); public void update(User user) this.userDaoImp.update(user); public void delete(Integer id) this.userDaoImp.delete(id);
六、编写controller层
编写UserController.java
package com.kszsa.user.controllor; import com.alibaba.fastjson.JSONObject; import com.kszsa.user.User; import com.kszsa.user.service.UserService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; @Controller @RequestMapping("/user") public class UserControllor @Autowired private UserService userService; @RequestMapping("hello") @ResponseBody public String hello(String name) userService.show(); return "hello12345,"+name; @RequestMapping("ceshi") public String ceshi() return "ceshi"; @RequestMapping("add") @ResponseBody public String add(User user) String result = "successs"; userService.add(user); return result; @RequestMapping("delete") @ResponseBody public JSONObject delete(Integer id) JSONObject jsonObject = new JSONObject(); Boolean success = true; String message = "删除用户成功"; try userService.delete(id); catch (Exception e) success = true; message = "删除用户异常，异常信息"+e.getMessage(); jsonObject.put("success",success); jsonObject.put("message",message); return jsonObject; @RequestMapping("update") @ResponseBody public JSONObject update(User user) JSONObject jsonObject = new JSONObject(); Boolean success = true; String message = "更新用户成功"; try userService.update(user); catch (Exception e) success = true; message = "更新用户异常，异常信息"+e.getMessage(); jsonObject.put("success",success); jsonObject.put("message",message); return jsonObject; @RequestMapping("get") @ResponseBody public User get(Integer id) return userService.getById(id);
七、编写前台页面
在webapp目录下，编写首页index.jsp
<html> <body> <h2>Hello World!</h2> </body> </html>
在webapp/WEB-INF/目录下，新建ceshi.jsp
<html> <head> <title>Title</title> </head> <body> AAAAAAAAAAAAAAAAAAAAAAAAAAAAA </body> </html>
至此，所有代码编写完成。
八、运行及接口测试
访问首页：http://localhost:8080/ssht/index.jsp
访问测试页面：http://localhost:8080/ssht/user/ceshi
访问hello，name的rest接口http://localhost:8080/ssht/user/hello?name=xiaodu
访问用户添加页面：http://localhost:8080/ssht/user/add?name=libai&description=shiren
去数据库中查询新增的记录
访问查询用户页面：http://localhost:8080/ssht/user/get?id=6
访问删除用户界面：http://localhost:8080/ssht/user/delete?id=6
到数据库中，查询，发现记录已经删除
