javaEE

Java Struts Hibernate Bean JSP

准备条件：
1．建WEB工程：ssh2
2．建数据库ssh2,表user
3．导入struts2,hibernate,spring包,注意包冲突，另导入commons-dbcp.jar, commons-pool.jar数据库连接池包
具体步骤如下：
1．实体类
1.1 User.java

package com.ssh2.bean;

public class User {
	
	private int id;
	private String firstname;
	private String lastname;
	private int age;
	
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getFirstname() {
		return firstname;
	}
	public void setFirstname(String firstname) {
		this.firstname = firstname;
	}
	public String getLastname() {
		return lastname;
	}
	public void setLastname(String lastname) {
		this.lastname = lastname;
	}
	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
	
}

2．数据库层
2.1 UserDAO.java

package com.ssh2.dao;

import java.util.List;

import com.ssh2.bean.User;

public interface UserDAO {
	public void saveUser(User user);
	public void updateUser(User user);
	public void deleteUser(User user);
	public List<User> getAllUsers();
	public User getUser(Integer id);
}

2.2 UserDAOImpl.java

package com.ssh2.dao.impl;

import java.util.List;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.ssh2.bean.User;
import com.ssh2.dao.UserDAO;

public class UserDAOImpl extends HibernateDaoSupport implements UserDAO {

	public void saveUser(User user) {
		this.getHibernateTemplate().save(user);
	}
	
	@SuppressWarnings("unchecked")
	public List<User> getAllUsers() {
		List<User> users=(List<User>)this.getHibernateTemplate().find("from User");
		return users;
	}
	
	public User getUser(Integer id) {
		return (User)this.getHibernateTemplate().get(User.class, id);
	}
	
	public void updateUser(User user) {
		this.getHibernateTemplate().saveOrUpdate(user);
	}
	
	public void deleteUser(User user) {
		this.getHibernateTemplate().delete(user);
	}
}

3．业务逻辑层
3.1 UserService.java

package com.ssh2.service;

import java.util.List;

import com.ssh2.bean.User;

public interface UserService {
	public void addUser(User user);
	public void updateUser(User user);
	public void deleteUser(User user);
	public List<User> getAllUsers();
	public User getUser(Integer id);
}

3.2 UserServiceImpl.java

package com.ssh2.service.impl;

import java.util.List;

import com.ssh2.bean.User;
import com.ssh2.dao.UserDAO;
import com.ssh2.service.UserService;

public class UserServiceImpl implements UserService {
	
	private UserDAO userDAO;
	
	public void setUserDAO(UserDAO userDAO) {
		this.userDAO = userDAO;
	}

	public void addUser(User user) {
		userDAO.saveUser(user);
	}
	
	public List<User> getAllUsers() {
		return userDAO.getAllUsers();
	}

	public User getUser(Integer id) {
		return userDAO.getUser(id);
	}
	
	public void updateUser(User user) {
		userDAO.updateUser(user);
	}
	
	public void deleteUser(User user) {
		userDAO.deleteUser(user);
	}
}

4．表示层

	}

	public void setUser(User user) {
		this.user = user;
	}
	
	public void setUserService(UserService userService) {
		this.userService = userService;
	}

	@Override
	public String execute() throws Exception {
		userService.addUser(user);
		return SUCCESS;
	}
}

import com.ssh2.service.UserService;

@SuppressWarnings("serial")
public class ListUserAction extends ActionSupport {

	private UserService userService;
	
	public void setUserService(UserService userService) {
		this.userService = userService;
	}

	@Override
	@SuppressWarnings("unchecked")
	public String execute() throws Exception {
		List<User> users=userService.getAllUsers();
	    Map request=(Map)ActionContext.getContext().get("request");
	    request.put("users", users);
		return SUCCESS;
	}
}

		return SUCCESS;
	}
}

9 楼 stuxnet 2013-01-23

struts 内action间的跳转要加"redirect-action"

8 楼 stuxnet 2013-01-23

亲，struts.xml怎么报错咧Invalid result location value/parameter

7 楼 stuxnet 2013-01-22

求项目war包或者rar包

6 楼 stuxnet 2013-01-22

不错求jar包，及相关的xml配置文件

xiaoyao7707 写道

楼主您好，您的http://lijunaccp.iteye.com/admin/blogs/838758

这个链接我看不了，在哪还能看到您的web.xml的配置呢

应该是可以看到的，主要内容是：

1.需要导入struts2-spring-plugin-2.1.8.1.jar包
这个包是Struts与spring整合的必须的
3.看下asm.jar文件有没有重复的，有的话保留asm.jar,删除另外一个。
4.web.xml中找到如下并改正，Struts2的核心类是下面这个。
<filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
5.想修改spring配置文件的位置
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/bean.xml</param-value>
</context-param>
6.web.xml例子如下：
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>

<filter>
<init-param>
<param-name>config</param-name>
<param-value>struts-default.xml,struts-plugin.xml,../struts.xml</param-value>
</init-param>
<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>

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

</web-app>

楼主很有心啊
写的灰常仔细

不过，美中不足的是 web.xml 文件的配置漏写了哈。。。。

期待楼主将功补过！

谢谢这位兄弟提醒，我也发现了这个问题，已在这个链接中写得很详细，谢谢指正。
