Maven项目整合SSH框架
---------------------siwuxie095
Maven 项目整合 SSH 框架
创建 Maven 项目 maven-ssh，项目目录结构如下：
将 src/main/java 展开如下：
具体实现如下：
1、在 Maven 项目的核心配置文件中进行配置
pom.xml：
<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.siwuxie095.maven</groupId> <artifactId>maven-ssh</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging>
<!-- 归类依赖 --> <properties> <struts.version>2.3.33</struts.version> <spring.version>4.3.7.RELEASE</spring.version> <hibernate.version>5.0.12.Final</hibernate.version> </properties>
<dependencies>
<!-- +++++++ (1) Struts2 相关 +++++++ -->
<!-- Struts2 相关的基本依赖 --> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-core</artifactId> <version>${struts.version}</version> <!-- 由于 Struts2 和 Hibernate 中都有 javassist， 为避免冲突，留下高版本，排除低版本即可
这里，Struts2 中的 javassist 版本更低 --> <exclusions> <exclusion> <groupId>javassist</groupId> <artifactId>javassist</artifactId> </exclusion> </exclusions> </dependency>
<!-- +++++++ (2) Spring 相关 +++++++ -->

<!-- Spring 单元测试相关的依赖 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency>
<!-- +++++++ (3) Hibernate 相关 +++++++ -->

<!-- jsp-api 相关的依赖 --> <dependency> <groupId>javax.servlet</groupId> <artifactId>jsp-api</artifactId> <version>2.0</version> <scope>provided</scope> </dependency>
</dependencies>
</project> |
2、在 src/main/webapp 目录下创建 JSP 页面
add.jsp：
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>添加用户</title> </head> <body>
<form action="${pageContext.request.contextPath }/user_add.action" method="post"> 用户名：<input type="text" name="username" /> 地址：<input type="text" name="address" /> <input type="submit" name="提交" /> </form>
</body> </html> |
succ.jsp：
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>添加成功</title> </head> <body>
<h1>添加成功！<a href="${pageContext.request.contextPath }/add.jsp">继续添加</a></h1>
</body> </html> |
3、在 src/main/java 目录下创建实体类，同时创建其
Hibernate 映射配置文件
User.java：
package com.siwuxie095.entity;
public class User {
Integer uid; String username; String address;
public Integer getUid() { return uid; } public void setUid(Integer uid) { this.uid = uid; }
public String getUsername() { return username; } public void setUsername(String username) { this.username = username; }
public String getAddress() { return address; } public void setAddress(String address) { this.address = address; }
@Override public String toString() { return "User [uid=" + uid + ", username=" + username + ", address=" + address + "]"; }
} |
User.hbm.xml：
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="com.siwuxie095.entity.User" table="t_user">
<id name="uid" column="uid"> <generator class="native"></generator> </id>
<property name="username" column="username"></property> <property name="address" column="address"></property>
</class>
</hibernate-mapping> |
4、在 src/main/resources 目录下创建 Hibernate 核心配置文件
hibernate.cfg.xml：
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory>
<property name="hibernate.show_sql">true</property> <property name="hibernate.format_sql">true</property> <!-- 注意：只有配置 hibernate.hbm2ddl.auto 为 update，才能自动创建表 --> <property name="hibernate.hbm2ddl.auto">update</property> <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property> <!-- 原来的配置： <property name="hibernate.current_session_context_class">thread</property>
在 SSH 框架整合中会报错，要么将这个配置删了，要么改成如下配置
参考链接：http://blog.csdn.net/maoyuanming0806/article/details/61417995 --> <property name="hibernate.current_session_context_class"> org.springframework.orm.hibernate5.SpringSessionContext </property> <!-- 如果没有如下配置，控制台将有如下异常信息： Disabling contextual LOB creation as createClob() method threw error : java.lang.reflect.InvocationTargetException
* 配置 * <property name="hibernate.temp.use_jdbc_metadata_defaults">false</property>
其实该配置加不加都无所谓，并不影响什么
参考链接：http://blog.csdn.net/jiong_long/article/details/51340685 --> <property name="hibernate.temp.use_jdbc_metadata_defaults">false</property>
<mapping resource="com/siwuxie095/entity/User.hbm.xml"/>
</session-factory> </hibernate-configuration> |
5、在 src/main/java 目录下创建 Action 类
UserAction.java：
package com.siwuxie095.action;
import com.opensymphony.xwork2.ActionSupport; import com.opensymphony.xwork2.ModelDriven; import com.siwuxie095.entity.User; import com.siwuxie095.service.UserService;
public class UserAction extends ActionSupport implements ModelDriven<User> {
private User user=new User();
@Override public User getModel() { return user; }
private UserService userService;
public void setUserService(UserService userService) { this.userService = userService; }
public String add() { userService.add(user); return "add"; }
} |
6、在 src/main/java 目录下创建 Service 类
UserService.java：
package com.siwuxie095.service;
import org.springframework.transaction.annotation.Transactional;
import com.siwuxie095.dao.UserDao; import com.siwuxie095.entity.User;
@Transactional public class UserService {
private UserDao userDao;
public void setUserDao(UserDao userDao) { this.userDao = userDao; }
public void add(User user) { userDao.add(user); }
} |
7、在 src/main/java 目录下创建 DAO 接口及其实现类
UserDao.java：
package com.siwuxie095.dao;
import com.siwuxie095.entity.User;
public interface UserDao {
void add(User user);
} |
UserDaoImpl.java：
package com.siwuxie095.dao.impl;
import org.springframework.orm.hibernate5.support.HibernateDaoSupport;
import com.siwuxie095.dao.UserDao; import com.siwuxie095.entity.User;
/** * 让 DAO 接口实现类继承 HibernateDaoSupport 类，直接获取 HibernateTemplate */ public class UserDaoImpl extends HibernateDaoSupport implements UserDao {
@Override public void add(User user) {
// 直接通过 this 获取 HibernateTemplate，调用 save() 方法保存 this.getHibernateTemplate().save(user);
/* * 此时，也可以获取 SessionFactory * * 法一：this.getSessionFactory() * 法二：this.getHibernateTemplate().getSessionFactory() * * * 此时，也可以获取 Session * * 法一：this.getSessionFactory().getCurrentSession() * 法二：... */ }
} |
8、在 src/main/resources 目录下创建 Struts2 核心配置文件
struts.xml：
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<package name="demo" extends="struts-default" namespace="/">
<action name="user_*" class="userAction" method="{1}"> <result name="add">/succ.jsp</result> </action>
</package>
</struts> |
9、在 src/main/resources 目录下创建 Spring 核心配置文件
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:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.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">
<!-- (1) --> <!-- 配置 C3P0 连接池 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="driverClass" value="com.mysql.jdbc.Driver"/> <!-- jdbc:mysql:///maven_db 是 jdbc:mysql://localhost:3306/maven_db 的简写 --> <property name="jdbcUrl" value="jdbc:mysql:///maven_db"/> <property name="user" value="root"/> <property name="password" value="8888"/> </bean>
<!-- SessionFactory 对象的创建交给 Spring 进行管理 --> <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean"> <!-- 因为在 Hibernate 核心配置文件中，没有数据库配置， 而是在 Spring 的核心配置文件中进行配置，所以需要 注入 dataSource LocalSessionFactoryBean 中有相关属性，所以可以 注入 --> <property name="dataSource" ref="dataSource"></property> <!-- 指定 Hibernate 核心配置文件的位置 --> <property name="configLocations" value="classpath:hibernate.cfg.xml"></property> </bean>
<!-- (2) --> <!-- 配置 Action 对象 --> <!-- 注意：由于 Action 对象是多实例的，所以服务器启动时， 不会被创建，只有在访问时，才会被创建 --> <bean id="userAction" class="com.siwuxie095.action.UserAction" scope="prototype"> <property name="userService" ref="userService"></property> </bean>
<!-- 配置 Service 对象 --> <bean id="userService" class="com.siwuxie095.service.UserService"> <property name="userDao" ref="userDaoImpl"></property> </bean>
<!-- 配置 Dao 实现类对象 --> <bean id="userDaoImpl" class="com.siwuxie095.dao.impl.UserDaoImpl"> <!-- 注入 SessionFactory 对象 --> <property name="sessionFactory" ref="sessionFactory"></property> </bean>
<!-- (3) --> <!-- 配置事务管理器 HibernateTransactionManager --> <bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager"> <!--注入 SessionFactory 对象 --> <property name="sessionFactory" ref="sessionFactory"></property> </bean>
<!-- 开启事务注解 --> <tx:annotation-driven transaction-manager="transactionManager"/>
</beans> |
10、在部署描述文件中进行配置
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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> <display-name>maven-ssh</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list>
<!-- 配置 Struts2 的核心过滤器 --> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter>
<filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
<!-- 配置 Spring 的监听器 ContextLoaderListener --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>
<!-- 配置 Spring 核心配置文件的位置（路径） --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param>
</web-app> |
11、访问路径
http://localhost:8080/maven-ssh/add.jsp
