使用axis1+spring+hibernate搭建webservice框架

原文使用axis1+spring+hibernate搭建webservice框架

源代码下载地址：http://www.zuidaima.com/share/1724478299180032.htm

写在前面的话：

       网上的教程大多都是使用wsdl2java工具构建webservice。本文则直接采用编辑server-config.wsdd来发布webservice，相比而言，可以比较快速的部署一个项目，适应工作需要。

   本教程模拟提供用户接口用于和别的系统结合，主要功能包括接受用户的增删改查。

一数据库创建

    创建数据库webservice

，创建用户表user

，用户表内容如下：

CREATE TABLE ` user ` (
`uid` int ( ) unsigned NOT NULL auto_increment,
`name` varchar ( ) NOT NULL default '' ,
`password` varchar ( ) NOT NULL default '' ,
`nickname` varchar ( ) NOT NULL default '' ,
PRIMARY KEY (`uid`)
) ENGINE=InnoDB DEFAULT CHARSET= gbk;

（您也可以直接使用附件中的sql文件创建数据库）

 

二新建web项目，搭建spring+hibernate框架。

1）新建用户模型，User类，如下：

package com.zuidaima.model;

public class User {
/*
* 用户属性，分别对应user表
*/
/*
* 用户id
*/
private Integer uid;
/*
* 用户名
*/
private String name;
/*
* 密码
*/
private String password;
/*
* 用户昵称
*/
private String nickname;

/*
* 必须提供一不带参数的构造方法，以供hibernate初始化User
*/
public User() {

}

/*
* 使用参数构建User
*/
public User(String name, String password, String nickname) {
this.name = name;
this.password = password;
this.nickname = nickname;
}

public Integer getUid() {
return uid;
}

public void setUid(Integer uid) {
this.uid = uid;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password = password;
}

public String getNickname() {
return nickname;
}

public void setNickname(String nickname) {
this.nickname = nickname;
}
}

另外user的配置文件User.hbm.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 2.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd" >

<hibernate-mapping>
<class name="com.zuidaima.model.User" table="user">
<id name="uid" type="java.lang.Integer" column="UID">
<generator class="native"></generator>
</id>
<property name="name" type="java.lang.String" column="NAME"
length="45" insert="true" update="true" />
<property name="password" type="java.lang.String" column="PASSWORD"
length="45" insert="true" update="true" />
<property name="nickname" type="java.lang.String" column="NICKNAME"
length="45" insert="true" update="true" />
</class>
</hibernate-mapping>

2）新建DAO,UserDAO类，如下：

package com.zuidaima.dao;

import java.util.List;

import org.springframework.orm.hibernate.support.HibernateDaoSupport;
import com.zuidaima.model.User;

public class UserDAO extends HibernateDaoSupport {
public User getUser(int uid) {
return (User) getHibernateTemplate().get(User.class, new Integer(uid));
}

/**
* 添加用户
*
* @param user
*/
public void saveUser(User user) {
getHibernateTemplate().save(user);
}

/**
* 删除用户
*
* @param uid
*/
public void deleteUser(int uid) {
StringBuffer strBuf = new StringBuffer();
strBuf.append("from User as u where u.uid=");
strBuf.append(uid);
getHibernateTemplate().delete(strBuf.toString());
}

/**
* 更新用户
*
* @param user
*/
public void updateUser(User user) {
getHibernateTemplate().saveOrUpdate(user);
}

/**
* 根据用户名查找用户
*
* @param name
* @return user or null
*/
/*
* return null if can't find
*/
public User getUserByName(String name) {
StringBuffer strBuf = new StringBuffer();
strBuf.append("select u from User as u where u.name='");
strBuf.append(name);
strBuf.append("'");
List tempList = getHibernateTemplate().find(strBuf.toString());
if (tempList != null && tempList.size() > 0) {
return (User) tempList.get(0);
} else {
return null;
}
}

/**
* 用户列表
*
* @return user List
*/
public List listUser() {
StringBuffer strBuf = new StringBuffer();
strBuf.append("select u from User as u ");
return getHibernateTemplate().find(strBuf.toString());
}

}

3）新建管理层，UserManager接口和其实现UserManagerImpl。

UserManager接口：

package org.yoo.service;

import java.util.List;

import org.yoo.model.User;

public interface UserManager {

/**
* 根据uid查找用户
* @param uid
* @return user
*/
public User getUserByUid( int uid);
/**
* 增加用户
* @param user
*/
public void saveUser(User user);
/**
* 删除用户
* @param uid
*/
public void deleteUser( int uid);

/**
* 更新用户信息
* @param user
*/
public void updateUser(User user);

/**
* 根据用户名查找用户
* @param name
* @return user
*/
public User getUserByName(String name);

/**
* 用户列表
* @return user List
*/
public List listUser();
}

UserManagerImpl如下：

package com.zuidaima.service.impl;

import java.util.List;

import com.zuidaima.dao.UserDAO;
import com.zuidaima.model.User;
import com.zuidaima.service.UserManager;

public class UserManagerImpl implements UserManager {
private UserDAO userDAO = null;

public void deleteUser(int uid) {
userDAO.deleteUser(uid);

}

public User getUserByName(String name) {

return userDAO.getUserByName(name);
}

public User getUserByUid(int uid) {

return userDAO.getUser(uid);
}

public List listUser() {

return userDAO.listUser();
}

public void saveUser(User user) {
userDAO.saveUser(user);

}

public void updateUser(User user) {
userDAO.updateUser(user);

}

/*
* Ioc By Spring
*/
public void setUserDAO(UserDAO userDAO) {
this.userDAO = userDAO;
}

}

 

4）配置xml文件。

Spring-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"
"http://www.springframework.org/dtd/spring-beans.dtd">

<beans>

<!-- ==DATA SOURCE======================================== -->
<!-- Data Source for MYSQL -->
<bean id="dataSource_MYSQL"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName">
<value>org.gjt.mm.mysql.Driver</value>
</property>
<property name="url">
<value>jdbc:mysql://127.0.0.1:3306/webservice?useUnicode=true&characterEncoding=GBK</value>
</property>
<property name="username">
<value>root</value>
</property>
<property name="password">
<value>111111</value>
</property>
</bean>

<!--==SESSION FACTORY===================================== -->
<!-- Hibernate SessionFactory -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate.LocalSessionFactoryBean">
<property name="dataSource">
<ref local="dataSource_MYSQL" />
</property>

<property name="mappingResources">
<list>
<value>com/zuidaima/model/mysql/User.hbm.xml</value>
</list>
</property>

<property name="hibernateProperties">
<props>
<!--sql dialect for MYSQL -->
<prop key="hibernate.dialect">
net.sf.hibernate.dialect.MySQLDialect
</prop>
<prop key="connection.pool.size">10</prop>
<prop key="statement_cache.size">25</prop>
<prop key="jdbc.fetch_size">50</prop>
<prop key="jdbc.batch_size">30</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="cglib.use_reflection_optimizer">true</prop>
</props>
</property>
</bean>
<!--==TRANSACTION======================================= -->
<!-- Transaction manager for a single Hibernate SessionFactory -->
<bean id="transactionManager"
class="org.springframework.orm.hibernate.HibernateTransactionManager">
<property name="sessionFactory">
<ref local="sessionFactory" />
</property>
</bean>
</beans>

Spring-dao.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"
"http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean id="userDAO" class="com.zuidaima.dao.UserDAO">
<property name="sessionFactory">
<ref bean="sessionFactory" />
</property>
</bean>
</beans>

Spring-service.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"
"http://www.springframework.org/dtd/spring-beans.dtd">

<beans>
<bean id="userManager" class="com.zuidaima.service.impl.UserManagerImpl">
<property name="userDAO">
<ref bean="userDAO" />
</property>
</bean>
</beans>

(您也可以将这三个文件合并在一个文件中，我将它们分开是觉得便于管理。另外如果这部分的配置您不明白，请先查看有关spring+hibernate的相关文章)

5）构建bean工厂

在此只前，都是和利用spring+hibernate搭建web项目一致，这一步开始要有些不同了。由于axis1不支持spring，所以无法直接创建spring的容器，我们需要自己构建bean工厂。

创建BeanxmlFactoryl类，如下：

package com.zuidaima.beanfactory;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.zuidaima.service.UserManager;

/**
* 单列模式的bean工厂类 SpringBean Factory
*
* @author yoo
*
*/
public class BeanxmlFactory {
private static BeanxmlFactory beanxmlfactory = null;
private UserManager userManager = null;

/*
* 私有的构造方法
*/
private BeanxmlFactory() {
/**
* 读取spring+hibernate的配置文件
*/
String[] configs = { "/spring-config.xml", "/spring-dao.xml",
"/spring-service.xml" };
ApplicationContext context = new ClassPathXmlApplicationContext(configs);
/*
* 获取制定的bean
*/
this.userManager = (UserManager) context.getBean("userManager");
}

/*
*
*/
public synchronized static BeanxmlFactory getInstance() {
if (beanxmlfactory == null) {
beanxmlfactory = new BeanxmlFactory();
}
return beanxmlfactory;
}

public UserManager getUserManager() {
return userManager;
}

}

到此我们的web项目已经搭建完成了，余下的事情就是构建webservice的服务了。

三构建service

1）新建一个类，我们命名它为UserService。该类利用由Spring提供的UserManager Bean，生产用户的增加和删除服务，如下：

package com.zuidaima.webservice;

import java.util.ArrayList;
import java.util.List;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import com.zuidaima.beanfactory.BeanxmlFactory;
import com.zuidaima.model.User;
import com.zuidaima.service.UserManager;

public class UserService {
private static Log log = LogFactory.getLog(UserService.class);
private UserManager userManager = null;

/*
* 获取spring提供的userManager bean
*/
public UserService() {
this.userManager = BeanxmlFactory.getInstance().getUserManager();
}

/**
* 使用信息创建用户
*
* @param name
*            用户名
* @param password
*            密码
* @param nickname
*            昵称
* @return user‘uid or error code 0 用户名已存在 -1 创建用户出错
*/
public int createUserByUserInfo(String name, String password,
String nickname) {
log.info("come in createUser method");
int resultCode = 0;
try {
User userTemp = userManager.getUserByName(name);
if (userTemp == null) {
User user = new User(name, password, nickname);
userManager.saveUser(user);
resultCode = user.getUid().intValue();
} else {
resultCode = 0;
}
} catch (Exception e) {
log.error("createUser have error:", e);
resultCode = -1;
}
return resultCode;
}

/**
* 删除用户
*
* @param uid
* @return boolean value
*/
public boolean deleteUser(int uid) {
log.info("come in deleteUser method");
boolean resultCode = true;
try {
userManager.deleteUser(uid);
} catch (Exception e) {
log.error("deleteUser have error:", e);
resultCode = false;
}
return resultCode;
}

}

2）添加axis1所需要的jar包。

复制axis-1_4"lib下所有的包到你的项目lib下。

(可以到apache网站上下载axis-1——4，或者在本文附件中获取)

3）Ok，最重要的一步，也是最奇妙的一步来了，构建server-config.wsdd，即利用axis1搭建webservice服务的描述文件。在web.xml同目录下，新建一xml文件，命名为server-config.wsdd文件类容如下：

<?xml version="1.0" encoding="UTF-8"?>
<deployment xmlns="http://xml.apache.org/axis/wsdd/"
xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
<globalConfiguration>
<parameter name="wsdlTargetNamespace" value="http://model.yoo.org" />
<parameter name="adminPassword" value="admin" />
<parameter name="attachments.implementation"
value="org.apache.axis.attachments.AttachmentsImpl" />
<parameter name="sendXsiTypes" value="true" />
<parameter name="sendMultiRefs" value="true" />
<parameter name="sendXMLDeclaration" value="true" />
<parameter name="axis.sendMinimizedElements" value="true" />
<requestFlow>
<handler type="java:org.apache.axis.handlers.JWSHandler">

</handler>

<parameter name="extension" value=".jwr" />
</handler>
</requestFlow>
</globalConfiguration>
<handler name="LocalResponder"
type="java:org.apache.axis.transport.local.LocalResponder" />
<handler name="URLMapper" type="java:org.apache.axis.handlers.http.URLMapper" />
<handler name="Authenticate"
type="java:org.apache.axis.handlers.SimpleAuthenticationHandler" />
<!--服务的名称 -->
<service name="UserService" provider="java:RPC">
<parameter name="scope" value="Request" />
<!--所有的方法都可以访问 -->
<parameter name="allowedMethods" value="*" />
<!-- 服务指向的类 -->
<parameter name="className" value="com.zuidaima.webservice.UserService" />
</service>
<!-- other service -->
<!-- 可以部署多个服务 -->
<!-- <service name="balabala" provider="java:RPC"> <parameter name="allowedMethods"
value="*"/> <parameter name="scope" value="Request"/> <parameter name="className"
value="balabala"/> </service> -->
<!-- axis1 -->
<service name="AdminService" provider="java:MSG">
<parameter name="allowedMethods" value="AdminService" />
<parameter name="enableRemoteAdmin" value="false" />
<parameter name="className" value="org.apache.axis.utils.Admin" />
<namespace>http://xml.apache.org/axis/wsdd/</namespace>
</service>
<service name="Version" provider="java:RPC">
<parameter name="allowedMethods" value="getVersion" />
<parameter name="className" value="org.apache.axis.Version" />
</service>
<transport name="http">
<requestFlow>
<handler type="URLMapper" />
<handler type="java:org.apache.axis.handlers.http.HTTPAuthHandler" />
</requestFlow>
</transport>
<transport name="local">
<responseFlow>
<handler type="LocalResponder" />
</responseFlow>
</transport>
</deployment>

4）最后一步，需要使用tomcat支持我们搭建的webservice。编辑web.xml，编辑后的文件内容如下：

<?xml version="1.0" encoding="ISO-8859-1"?>

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web

</servlet-mapping>

<!-- uncomment this if you want the admin servlet -->
<!-- <servlet-mapping> <servlet-name>AdminServlet</servlet-name> <url-pattern>/servlet/AdminServlet</url-pattern>
</servlet-mapping> -->

<session-config>
<!-- Default to 5 minute session timeouts -->
<session-timeout>5</session-timeout>
</session-config>

<!-- currently the W3C havent settled on a media type for WSDL; http://www.w3.org/TR/2003/WD-wsdl12-20030303/#ietf-draft for now we go with the basic 'it's XML' response -->
<mime-mapping>

<welcome-file>index.jsp</welcome-file>
<welcome-file>index.html</welcome-file>
<welcome-file>index.jws</welcome-file>
</welcome-file-list>

</web-app>

到此，我们可以歇口气啦，我们已经搭建好了一个简单的webservice了。

项目截图：



该项目由于我对webservice不熟悉，所以只是把文档涉及到的代码搭建成了maven工程，花了不少时间也没验证通过，大家谁有能力的帮忙验证下吧。
