Spring 整合WebService示例

Java常见的建立webService的方式有三种，Axis2（下载：http://axis.apache.org/axis2/java/core/download.cgi）、由JDK开发和Apache CXF等等。这里写一个CXF的例子。

首先是建立一个Web Service 工程，在配置文件web.xml中配置过滤器启动项等

<?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"><display-name></display-name><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list><!-- apach cxf --><servlet><servlet-name>CXFServlet</servlet-name><servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>CXFServlet</servlet-name><url-pattern>/services/*</url-pattern></servlet-mapping><!-- spring --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></context-param><filter><filter-name>openSessionInView</filter-name><filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class><init-param><param-name>sessionFactoryBeanName</param-name><param-value>sessionFactory</param-value></init-param><init-param><param-name>singleSession</param-name><param-value>true</param-value></init-param><init-param><param-name>flushMode</param-name><param-value>AUTO</param-value></init-param></filter><filter-mapping><filter-name>openSessionInView</filter-name><url-pattern>/*</url-pattern></filter-mapping><!-- 已以下是自定义的过滤器，当然这是非必须的 --><filter><filter-name>struts2</filter-name><filter-class>com.gc.filter.StrutsFilter</filter-class></filter><filter-mapping><filter-name>struts2</filter-name><url-pattern>/*</url-pattern></filter-mapping></web-app>

spring的容器的配置：以下是applicationContext.xml文件，请注意xmlns的应用问题

<?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:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context"xmlns:jaxws="http://cxf.apache.org/jaxws" xmlns:jaxrs="http://cxf.apache.org/jaxrs"xsi:schemaLocation="   http://www.springframework.org/schema/beans    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd   http://www.springframework.org/schema/tx    http://www.springframework.org/schema/tx/spring-tx-3.0.xsd   http://www.springframework.org/schema/aop    http://www.springframework.org/schema/aop/spring-aop-3.0.xsd   http://www.springframework.org/schema/context    http://www.springframework.org/schema/context/spring-context-3.0.xsd   http://cxf.apache.org/jaxws    http://cxf.apache.org/schemas/jaxws.xsd    http://cxf.apache.org/jaxrs    http://cxf.apache.org/schemas/jaxrs.xsd">           <context:spring-configured />    <context:component-scan base-package="com.gc" /><beanclass="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"><property name="locations"><value>classpath:jdbc.properties</value></property></bean><bean id="dataSource" destroy-method="close"class="org.apache.commons.dbcp.BasicDataSource"><property name="driverClassName" value="${jdbc.driverClassName}" /><property name="url" value="${jdbc.url}" /><property name="username" value="${jdbc.username}" /><property name="password" value="${jdbc.password}" /><property name="maxActive" value="${jdbc.maxActive}"/><property name="maxIdle" value="${jdbc.maxIdle}"/><property name="maxWait" value="${jdbc.maxWait}"/><property name="defaultAutoCommit" value="${jdbc.defaultAutoCommit}"/></bean><!-- 注解 sessionFactory --><bean id="sessionFactory"class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"><property name="dataSource" ref="dataSource" /><property name="packagesToScan"><list><value>com.gc.model</value></list></property><property name="hibernateProperties"><props><prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop><prop key="hibernate.hbm2ddl.auto">update</prop><prop key="hibernate.show_sql">true</prop><prop key="hibernate.show_formate">true</prop></props></property></bean><!-- 配置 hibernateTemplate  --><bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate"><property name="sessionFactory" ref="sessionFactory"></property></bean><!-- 事务控制 --><bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"><property name="sessionFactory" ref="sessionFactory" /></bean> <tx:annotation-driven transaction-manager="txManager" /> <aop:config><aop:pointcut expression="execution(* com.gc.service.*.*(..))" id="bussinessService"/><aop:advisor pointcut-ref="bussinessService" advice-ref="txAdvice"/></aop:config><tx:advice id="txAdvice" transaction-manager="txManager">    <tx:attributes>   <tx:method name="get*" read-only="true" propagation="NOT_SUPPORTED"/>   <tx:method name="find*" read-only="true" propagation="NOT_SUPPORTED"/>   <tx:method name="regist*" propagation="REQUIRED"/>   <tx:method name="add*" propagation="REQUIRED"/>    <tx:method name="save*" propagation="REQUIRED"/>    <tx:method name="update*" propagation="REQUIRED"/>    <tx:method name="del*" propagation="REQUIRED"/>    </tx:attributes></tx:advice>  <!-- 配置 webservice 接口 --><import resource="classpath:META-INF/cxf/cxf.xml" />   <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml"/>   <import resource="classpath:META-INF/cxf/cxf-servlet.xml" />     <jaxws:endpoint id="userManagerWs" implementor="com.gc.webservice.UserManagerImpl" address="/userManager"/>  </beans>

另附上jdbc.properties和log4j.properties的文件配置

jdbc.driverClassName=com.mysql.jdbc.Driverjdbc.url=jdbc:mysql://localhost:3306/ssh_cxfjdbc.username=rootjdbc.password=rootjdbc.maxActive=100jdbc.maxIdle=30jdbc.maxWait=500jdbc.defaultAutoCommit=true

log4j.appender.stdout=org.apache.log4j.ConsoleAppenderlog4j.appender.stdout.Target=System.outlog4j.appender.stdout.layout=org.apache.log4j.PatternLayoutlog4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c:%L - %m%nlog4j.rootLogger=warn, stdoutlog4j.logger.org.hibernate.tool.hbm2ddl=debug

至于java的文件的书写方式和通常的ssh2开发相识，这里面struts2用到的不多，可用可不用。下面是层次结构图

  只是在spring的配置中加上webservice的内容，在webservice包中注解上webservice，代码如下：

IUserManager接口：

package com.gc.webservice;import java.util.List;import javax.jws.WebService;import com.gc.model.Product;import com.gc.model.User;@WebServicepublic interface IUserManager {public User getUser(String username, String password);public List<User> getUsers();public String addProduct(Product product);public List<Product> getProducts(String productCode, String productName, String userId);public Product getProductById(int productId);public String updateProduct(Product product);public void delProducts(String productIds);}

userManager接口的实现类

package com.gc.webservice;import java.util.List;import javax.annotation.Resource;import com.gc.model.Product;import com.gc.model.User;import com.gc.service.ProductService;import com.gc.service.UserService;public class UserManagerImpl implements IUserManager {private UserService userService;private ProductService productService;public UserService getUserService() {return userService;}@Resourcepublic void setUserService(UserService userService) {this.userService = userService;}public ProductService getProductService() {return productService;}@Resourcepublic void setProductService(ProductService productService) {this.productService = productService;}@Overridepublic User getUser(String username, String password) {return userService.getUser(username, password);}@Overridepublic List<User> getUsers() {return userService.getAllUsers();}@Overridepublic String addProduct(Product product) {return productService.addProduct(product);}@Overridepublic List<Product> getProducts(String productCode, String productName,String userId) {return productService.getProducts(productCode, productName, userId);}@Overridepublic Product getProductById(int productId) {return productService.getProductById(productId);}@Overridepublic String updateProduct(Product product) {return productService.updateProduct(product);}@Overridepublic void delProducts(String productIds) {productService.delProducts(productIds);}}
