[Java] SSH框架笔记_框架整合示例(一)

本文描述的是框架SSH集成的示例，由于在这个过程中有一些小的细节容易被遗忘，特别撰写了一篇小的博文来记录这个过程，希望对自己以及后来者能够起到积极意义。

本文中使用的框架和版本号为：

struts-2.3.1.2、hibernate-3.6.10、spring-3.1.1

其下载地址分别为：

http://struts.apache.org/download.cgi#struts2312

http://sourceforge.net/projects/hibernate/files/hibernate3/3.6.10.Final/

http://www.springsource.org/download/community?project=Spring%2520Framework&version=3.1.1.RELEASE

分别将其解压，需要注意的是本例中hibernate3还需要的是log4j，spring还需要commons-loging、commons-dbcp和commons-pool，在这里就不再赘述出其下载地址了。

需要删除的重复包为：asm-commons-3.3.jar和javassist-3.11.0.GA.jar

需要使用的JAR包截图：

 接下来在jee中新建一个Dynamic Web Project，选择好运行环境：

 相关文件组织如下：

 源代码列举如下：

UserAction.java

package com.ssh.action;import com.opensymphony.xwork2.ActionSupport;
import com.ssh.pojo.User;
import com.ssh.service.UserService;

public class UserAction extends ActionSupport {

    private static final long serialVersionUID = 1L;

    private User user;
    private UserService service;
    public UserService getService() {
        return service;
    }
    public void setService(UserService service) {
        this.service = service;
    }
    public User getUser() {
        return user;
    }
    public void setUser(User user) {
        this.user = user;
    }

    public String execute(){
        if (service.save(user)!=null) {
            return SUCCESS;
        }else {
            return ERROR;
        }
    }
}

 User.java

package com.ssh.pojo;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name="user")
public class User {
    private Integer id;
    private String username;
    private String password;
    @Id
    @GeneratedValue
    @Column(name="hr_id")
    public Integer getId() {
        return id;
    }
    public void setId(Integer 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;
    }
}

 UserService.java

package com.ssh.service;

import org.hibernate.Session;
import org.hibernate.SessionFactory;

import com.ssh.pojo.User;

public class UserService {
    private SessionFactory factory = null;
    public SessionFactory getFactory() {
        return factory;
    }
    public void setFactory(SessionFactory factory) {
        this.factory = factory;
    }
    public User save(User user){
        Session session = factory.getCurrentSession();
        session.beginTransaction();
        session.save(user);
        session.getTransaction().commit();
        return user;
    }
}

 log4j.properties

### direct log messages to stdout ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

#log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### set log levels - for more verbose logging change 'info' to 'debug' ###

log4j.rootLogger=warn, stdout

#log4j.logger.org.hibernate=info
#log4j.logger.org.hibernate=debug

### log HQL query parser activity
#log4j.logger.org.hibernate.hql.ast.AST=debug

### log just the SQL
#log4j.logger.org.hibernate.SQL=debug

### log JDBC bind parameters ###
#log4j.logger.org.hibernate.type=info
#log4j.logger.org.hibernate.type=debug

### log schema export/update ###
log4j.logger.org.hibernate.tool.hbm2ddl=debug

### log HQL parse trees
#log4j.logger.org.hibernate.hql=debug

### log cache activity ###
#log4j.logger.org.hibernate.cache=debug

### log transaction activity
#log4j.logger.org.hibernate.transaction=debug

### log JDBC resource acquisition
#log4j.logger.org.hibernate.jdbc=debug

### enable the following line if you want to track down connection ###
### leakages when using DriverManagerConnectionProvider ###
#log4j.logger.org.hibernate.connection.DriverManagerConnectionProvider=trace

 然后在Tomcat7上部署该项目即可，在浏览器中输入地址：http://localhost:8080/ssh_demo/register即可进入下面的页面：

 至此，SSH框架整合完成。
