本文介绍了Java项目的创建与配置，包括创建项目、构建目录结构。详细阐述了Struts2、Spring和Hibernate的集成过程，如引入依赖、配置相关文件、创建测试类等，还说明了部署和启动测试的步骤，以及解决部分错误的方法。
一。创建项目
先附上测试的数据库
DROP TABLE IF EXISTS `user`; CREATE TABLE `user` ( `id` int(5) NOT NULL AUTO_INCREMENT, `name` varchar(10) COLLATE utf8_bin DEFAULT NULL, `password` varchar(10) COLLATE utf8_bin DEFAULT NULL, `remark` varchar(50) COLLATE utf8_bin DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8 COLLATE=utf8_bin; -- ---------------------------- -- Records of user -- ---------------------------- INSERT INTO `user` VALUES ('1', 'zhangsan', '123456', null); INSERT INTO `user` VALUES ('2', 'lisi', '123', null); INSERT INTO `user` VALUES ('3', 'wangan', '456', null); INSERT INTO `user` VALUES ('4', 'xinxi', '000', null);
1.new->project出现如下
点击next后出现如下填写GroupId和ArtifactId在点击next直至finish
2.构建目录结构
在main下新建java和resources目录如下并将java目录标记为Sources Root，resources标记为Resources Root
在java下新建如下包package
二。Struts2
1.首先引入struts2依赖
注：如果引入所有（spring和hibernate）依赖则在struts.xml中的对应action的类class就会找不到
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-core</artifactId>
<version>2.5.1</version>
</dependency>
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-json-plugin</artifactId>
<version>2.5.1</version>
<scope>compile</scope>
</dependency>
2.WEB-INF下web.xml文件配置
<?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_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>Archetype Created Web Application</display-name> <!--Hibernate Open Session in View Filte --> <!-- <filter> <filter-name>hibernateFilter</filter-name> <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class> singleSession默认为true,若设为false则等于没用OpenSessionInView <init-param> <param-name>singleSession</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>hibernateFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> --> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
3.在resources下添加struts.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<!-- Struts。xml的配置文件 -->
<!-- 所有匹配*.action的请求都由struts2处理 -->
<constant name="struts.action.extension" value="action,," />
<!-- 是否启用开发模式 -->
<constant name="struts.devMode" value="true" />
<package name="default" extends="struts-default" namespace="/">
<!-- 如果不指定method，那么默认方法是execute-->
<!--name:Action类的名字，具有唯一性，页面上通过name来访问Action类 -->
<action name="test" class="com.well.liu.action.TestAction" method="test">
<!-- 配置结果集 :name属性的值一定要与execute方法的返回值一致-->
<result name="test">test.jsp</result>
</action>
</package>
</struts>
4.在action包下创建TestAction类，为了测试在webapp下新建了test.jsp页面
package com.well.liu.action; import com.opensymphony.xwork2.ActionSupport; public class TestAction extends ActionSupport { public String test(){ System.out.println("测试struts2"); return "test"; } }
5.部署
点击如下图
点击+号找到Local
接下来修改名字，选择Deployment点击+号，选择ssh:war exploded,另外Application context填写的如果是ssh，那么访问的时候就是localhost:8080/ssh,部署结束。
6.启动测试
启动后默认访问的是index.jsp页面，可以访问http://localhost:8080/ssh/test
如果页面乱码在头部加上<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
三。Spring
1.首先引入spring相关依赖
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>3.0.6.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>3.0.6.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>3.0.6.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>3.0.6.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-orm</artifactId>
<version>3.0.6.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-tx</artifactId>
<version>3.0.6.RELEASE</version>
</dependency>
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjweaver</artifactId>
<version>1.8.4</version>
</dependency>
<dependency>
<groupId>commons-logging</groupId>
<artifactId>commons-logging</artifactId>
<version>1.2</version>
</dependency>
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-spring-plugin</artifactId>
<version>2.5.1</version>
</dependency>
2.在web.xml中添加listener,并在resources下新建spring,xml文件
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring.xml</param-value>
</context-param>
spring.xml文件
<?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:mvc="http://www.springframework.org/schema/mvc" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:amq="http://activemq.apache.org/schema/core" xmlns:task="http://www.springframework.org/schema/task" 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/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://activemq.apache.org/schema/core http://activemq.apache.org/schema/core/activemq-core.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-4.0.xsd"> <bean id="test" class="com.well.liu.action.TestAction"> </bean> </beans>
如果你的spring.xml文件uri地址出错，解决点击菜单栏“File”→“Settings”→“Languages&Frameworks”
将之前的struts.xml中的<action name="test" class="com.well.liu.action.TestAction" method="test">class改为"test",也就是说与spring.xml中bean的id相对应，然后运行即可
四。Hibernate
1.引入hibernate依赖
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>3.6.5.Final</version>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.34</version>
</dependency>
<dependency>
<groupId>commons-dbcp</groupId>
<artifactId>commons-dbcp</artifactId>
<version>1.4</version>
</dependency>
2.View--》Tool windows---->Database
找到所需连接的数据库
依次填写如下即可
右键点击项目添加support支持
找到Hibernate并且打勾添加 import database schema打勾 含义:导入数据库模式
填写如下信息（数据源、实体生成包model位置、勾选需要生成的实体、勾选右下角最下面的两个按钮）即可生成实体和映射文件
3.编写代码
spring.xml文件
<?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:mvc="http://www.springframework.org/schema/mvc" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:amq="http://activemq.apache.org/schema/core" xmlns:task="http://www.springframework.org/schema/task" 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/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://activemq.apache.org/schema/core http://activemq.apache.org/schema/core/activemq-core.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-4.0.xsd"> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://localhost:3306/user?characterEncoding=utf-8" /> <property name="username" value="root" /> <property name="password" value="root" /> </bean> <!--SessionFactory配置--> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean" destroy-method="destroy"> <property name="dataSource" ref="dataSource"/> <property name="mappingResources"> <list> <value>com/well/liu/model/UserEntity.hbm.xml</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop> <prop key="hibernate.show_sql">false</prop> </props> </property> </bean> <bean id="userDao" class="com.well.liu.dao.UserDao"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <bean id="test" class="com.well.liu.action.TestAction"> <property name="userService" ref="userService"></property> </bean> <bean id="userService" class="com.well.liu.service.impl.UserServiceImpl"> <property name="userDao" ref="userDao"></property> </bean> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"></property> </bean> <!-- 定义事务通知 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <!-- 定义方法的过滤规则 --> <tx:attributes> <!-- 所有方法都使用事务 --> <tx:method name="*" propagation="REQUIRED"/> </tx:attributes> </tx:advice> <!-- 定义AOP配置 --> <aop:config> <!-- 定义一个切入点 --> <aop:pointcut expression="execution (* com.well.liu.service.*.*(..))" id="services"/> <!-- 对切入点和事务的通知，进行适配 --> <aop:advisor advice-ref="txAdvice" pointcut-ref="services"/> </aop:config> </beans>
在包dao下新建UserDao
package com.well.liu.dao; import com.well.liu.model.UserEntity; import org.springframework.orm.hibernate3.support.HibernateDaoSupport; public class UserDao extends HibernateDaoSupport { public UserEntity getUser(int id){ return this.getHibernateTemplate().get(UserEntity.class,id); } }
在包service下新建UserService
package com.well.liu.service; import com.well.liu.model.UserEntity; public interface UserService { public UserEntity getUser(int id); }
在包impl下新建UserServiceImpl
package com.well.liu.service.impl; import com.well.liu.dao.UserDao; import com.well.liu.model.UserEntity; import com.well.liu.service.UserService; public class UserServiceImpl implements UserService { private UserDao userDao; public UserDao getUserDao() { return userDao; } public void setUserDao(UserDao userDao) { this.userDao = userDao; } @Override public UserEntity getUser(int id) { UserEntity userEntity = userDao.getUser(id); return userEntity; } }
TestAction类
package com.well.liu.action; import com.opensymphony.xwork2.ActionSupport; import com.well.liu.model.UserEntity; import com.well.liu.service.UserService; public class TestAction extends ActionSupport { private UserService userService; public UserService getUserService() { return userService; } public void setUserService(UserService userService) { this.userService = userService; } public String test(){ UserEntity userEntity = userService.getUser(1); System.out.println(userEntity); return "test"; } }
启动后会报如下错误
在网上找了资料将classpath改成classpath*、在pom中增加配置都还是同样的问题
最后将UserEntity.hbm.xml移动到resources下启动成功后后访问http://localhost:8080/ssh/test，出现地址则成功
