Maven4MyEclipse 搭建ssh2+extjs项目(4)struts2.3.4+hibernate4.2.0+spring3.1.2
1编辑pom.xml
1.1加入第3方依赖包
<dependencies> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.0.1</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.6.8.RELEASE</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.14</version> </dependency> <dependency> <groupId>javassist</groupId> <artifactId>javassist</artifactId> <version>3.9.0</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.0.5</version> </dependency> <dependency> <groupId>cglib</groupId> <artifactId>cglib</artifactId> <version>2.2.2</version> </dependency>
1.2 加入struts2相关包
<dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-spring-plugin</artifactId> <version>2.3.4</version> </dependency> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-core</artifactId> <version>2.3.4</version> </dependency>

1.4加入spring相关包
<dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>3.1.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>3.1.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>3.1.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>3.1.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-asm</artifactId> <version>3.1.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>3.1.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>3.1.2.RELEASE</version> </dependency>
2.编辑web.xml
<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> </filter> <filter> <filter-name>hibernateOpenSessionInViewFilter</filter-name> <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class> </filter> <filter> <filter-name>struts2</filter-name> <filter-class> org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter </filter-class> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <filter-mapping> <filter-name>hibernateOpenSessionInViewFilter</filter-name> <url-pattern>*.action</url-pattern> </filter-mapping> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>*.action</url-pattern> </filter-mapping> <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> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener>（编码，struts2过滤器，spring监听器，防止内存泄露过滤器，OpenSessionInViewFilter）
3.编辑application.xml
<!-- 使用annotation 自动注册bean,并保证@Required,@Autowired的属性被注入 -->
<context:component-scan base-package="com.jjee" />
<!-- DataSource 详细参数可以参考个人知识管理的C3P0的详细配置说明详解 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
destroy-method="close">
<property name="driverClass" value="com.mysql.jdbc.Driver" />
<property name="jdbcUrl"

</bean>
<bean id="sessionFactory"

4.配置struts.xml
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"> <struts> <constant name="struts.devMode" value="true" /> <package name="basicstruts2" extends="struts-default"> <action name="index" class="com.jjee.web.Action_"> <result name="success">/success.jsp</result> <result name="error">/error.jsp</result> </action> </package> </struts>顺便配置要测试的action
5.测试
5.1.保存数据
分3层的包
Action_.java
package com.jjee.web;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import com.jjee.service.UserService;
import com.opensymphony.xwork2.ActionSupport;
public class Action_ extends ActionSupport {
private static final Logger logger = Logger.getLogger(Action_.class);
/*
* (non-Javadoc)
*
* @see com.opensymphony.xwork2.ActionSupport#execute()
*/
@Autowired
protected UserService userService;
@Override
public String execute() throws Exception {
// TODO Auto-generated method stub\
try {
if (userService.save()) {
return "success";
}
} catch (Exception e) {
return "error";
}
return "success";
}
}
UserService.java
package com.jjee.service;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.jjee.dao.BaseDao;
import com.jjee.entity.User;
import com.jjee.web.Action_;
@Service
public class UserService {
private static final Logger logger = Logger.getLogger(Action_.class);
@Autowired
protected BaseDao baseDao;
public boolean save() throws Exception {
// TODO Auto-generated method stub
logger.debug("debug===============");
User user = new User();
user.setName("这是用户名11111111111111");
baseDao.save(user);
return true;
}
}
BaseDao.java
package com.jjee.dao;
import java.io.Serializable;
import java.util.List;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.criterion.Example;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
/**
*
* @ClassName:BaseDao
* @Description:dao 基类，包括增删改查
* @author:gaoFeng
* @date:2013-2-27 下午2:31:42
*/
@Repository
public class BaseDao extends ReadDao implements Serializable {
@Autowired
private SessionFactory sessionFactory;
public Session getSession() {
return sessionFactory.getCurrentSession();
}
public <T> void save(T t) throws Exception {
getSession().save(t);
//throw new Exception("==================asdf");
}只贴上来保存数据的代码
User.java
package com.jjee.entity;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import static javax.persistence.GenerationType.IDENTITY;
import javax.persistence.Id;
import javax.persistence.Table;
/**
* User entity. @author MyEclipse Persistence Tools
*/
@Entity
@Table(name = "user", catalog = "jjee")
public class User implements java.io.Serializable {
// Fields
private Integer id;
private String name;
// Constructors
/** default constructor */
public User() {
}
/** full constructor */
public User(String name) {
this.name = name;
}
// Property accessors
@Id
@GeneratedValue(strategy = IDENTITY)
@Column(name = "id", unique = true, nullable = false)
public Integer getId() {
return this.id;
}
public void setId(Integer id) {
this.id = id;
}
@Column(name = "name", length = 10)
public String getName() {
return this.name;
}
public void setName(String name) {
this.name = name;
}
}部署测试一下
查看数据表
5.2测试事务回滚
加上抛异常代码
页面测试
看数据表
看后台显示
ok测试成功
