2019獨角獸企業重金招聘Python工程師標準>>>

一、準備

軟件環境：

JDK1.8, Eclipse JEE 4.4, Maven-3.2.5, Spring-4, CXF-3.1.5

二、創建項目

新建一個Maven項目，在pom.xml里添加spring依賴

<dependencyManagement><dependencies><dependency><groupId>io.spring.platform</groupId><artifactId>platform-bom</artifactId><version>1.1.3.RELEASE</version><type>pom</type><scope>import</scope></dependency></dependencies> </dependencyManagement>

添加cxf依賴，或是從apache cxf官網下載已編譯的文件，通過BuildPath添加

<dependency><groupId>org.apache.cxf</groupId><artifactId>apache-cxf</artifactId><version>3.1.5</version><type>zip</type> //因為Maven遠程倉庫只有zip，tar.gz等壓縮包，沒有對應jar包，所有要指定type </dependency>

用過BuildPath添加 右鍵項目---》 Build Path---》 Configure Build Path---》 Add Library---》 在對話框中選擇CXF Runtime---》 如果是第一自使用CXF，則需要配置CXF，點擊Configure installed runtimes，新增一個CXF---》 添加成功，在Libraries里會多出一個Apache CXF Libary[3.1.5]

三、編寫類文件

新建一個接口類

@WebService public interface ICXFService{@WebMethodpublic String sayHello(@WebParam(name="username") String username); }

說明： @WebService：標記表示該接口是一個WebService服務。 @WebMethod：標記表示WebService中的方法。 @WebParam(name="paramName")表示方法中的參數，name屬性限制了參數的名稱，若沒有指定該屬性，參數將會被重命名。

新建一個實現類

public class CXFService implements ICXFService{public String sayHello(String username){return "Hello, "+username; } }

在WEB-INF下新建cxf-servlet.xml

<?xml version="1.0" encoding="UTF-8"?> <!-- Licensed to the Apache Software Foundation (ASF) under one or more contributor license agreements.

在web.xml中添加cxf配置信息

<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>/*</url-pattern> </servlet-mapping><session-config><session-timeout>60</session-timeout> </session-config>

在src\main\resources下新建client-beans.xml

<?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:jaxws="http://cxf.apache.org/jaxws"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://cxf.apache.org/jaxwshttp://cxf.apache.org/schema/jaxws.xsd"> <bean id="client" class="com.demo.cxfws.service.ICXFService" factory-bean="clientFactory" factory-method="create" /><bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean"><property name="serviceClass" value="com.demo.cxfws.service.ICXFService" /><property name="address" value="http://localhost:8080/cxfws/sayHello" /></bean> </beans>

編寫測試

public class TestCXF {public static void main(String[] args) {ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] {"client-beans.xml"});ICXFService service = (ICXFService) context.getBean("client");String str = service.sayHello("zhangsan");System.out.println(str);} }

四、遇到的問題

Eclipse在創建Maven的時候會創建index.jsp文件。而pom.xml文件里只有junit依賴，所有還需手動添加servlet-api

<dependency><groupId>javax.servlet</groupId><artifactId>servlet-api</artifactId><version>2.5</version> </dependency>

還有一個問題如下Eclipse JAX-RS (REST Web Services) 2.0 requires Java 1.6 or newer

如果遇到了，在pom.xml添加：

<build><plugins><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><version>3.1</version><configuration><source>1.8</source><target>1.8</target></configuration></plugin></plugins> </build>

如果還不行，右鍵項目，點擊Properties，在Java Compiler里選擇Compiler Level為1.8

項目報錯提示沒有src\main\java，src\test\resources，src\test\java等文件夾

解決辦法：進入Java Build Path下的Source選卡，移除打小紅叉的文件夾，然后自己右鍵項目新建Source Folder。
