spring 整合cxf 第二彈（經過測試）以xml格式進行資料互動
阿新 • • 發佈：2019-02-19
為方便打大家學習以及應用，還是從配置檔案、jar、bean開始扯起。。。。。。
1,web.xml 配置檔案基本配置
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <display-name>Spring MVC Application</display-name> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:spring-cxf.xml</param-value> </context-param> <servlet> <servlet-name>mvc-dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>mvc-dispatcher</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <!--spring 整合cxf web配置--> <servlet> <servlet-name>CXFServlet</servlet-name> <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class> </servlet> <!-- CXFServlet Mapping --> <servlet-mapping> <servlet-name>CXFServlet</servlet-name> <url-pattern>/cxf/*</url-pattern> </servlet-mapping> </web-app>
這裡配置的cxf servlet的對應關係，我的攔截路徑是/cxf/ 下的所有url。
2，pom.xml 配置檔案，新增cxf開發需要的maven依賴
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.springapp</groupId> <artifactId>WebCxf</artifactId> <packaging>war</packaging> <version>1.0-SNAPSHOT</version> <name>WebCxf</name> <properties> <spring.version>4.1.1.RELEASE</spring.version> </properties> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <version>2.1</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> <scope>test</scope> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency> <!--CXF 依賴--> <!-- https://mvnrepository.com/artifact/org.apache.cxf/apache-cxf --> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>apache-cxf</artifactId> <version>3.1.10</version> </dependency> </dependencies> <build> <finalName>WebCxf</finalName> <plugins> <plugin> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.6</source> <target>1.6</target> </configuration> </plugin> <plugin> <artifactId>maven-surefire-plugin</artifactId> <configuration> <includes> <include>**/*Tests.java</include> </includes> </configuration> </plugin> </plugins> </build> </project>
3，簡單的spring配置檔案，這裡不多講了。
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> <!--註解驅動--> <mvc:annotation-driven/> <context:component-scan base-package="com.spring"/> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/pages/"/> <property name="suffix" value=".jsp"/> </bean> </beans>
4，針對cxf 實現的需要，增加spring-cxf.xml 配置檔案，這裡在web.xml 裡已經做了引入
<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/beans
http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
http://cxf.apache.org/jaxws
http://cxf.apache.org/schemas/jaxws.xsd">
<!-- Import Apache CXF Bean Definition -->
<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"/>
<!--模擬服務端① webservice-->
<bean id="hello" class="com.spring.service.impl.HelloWordServiceImpl"/>
<!--implementor="#hello" 指向bean id="hello"-->
<jaxws:endpoint id="helloWorld" implementor="#hello" address="/helloWorld" />
<!--模擬服務端②-->
<bean id="user" class="com.spring.service.impl.UserServiceImpl"/>
<jaxws:endpoint id="userPoint" implementor="#user" address="/user"/>
<!--模擬客戶端①-->
<jaxws:client id="client"
serviceClass="com.spring.service.IHelloWord"
address="http://localhost:8080/cxf/helloWorld" />
<!--模擬客戶端②-->
</beans>這裡demo應用的是<!--模擬服務端②-->的這個配置，其他與當前的demo沒有關係。
5，針對xml格式的資料 實現的工具封裝的實現。
package com.spring.utils;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
import org.xml.sax.InputSource;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.StringReader;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
/**
*生成xml格式的檔案
* 解釋xml格式的字串
*/
public class XMLHandler {
/**
* 建立xml
* @return
*/
public static String createXML(){
String xmlStr="";
//doc 的工廠
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
try{
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.newDocument();
document.setXmlVersion("1.0");
//
Element root = document.createElement("root");
document.appendChild(root);
//
Element user = document.createElement("user");
//
Element id = document.createElement("id");
id.setTextContent("1");
user.appendChild(id);
//
Element name = document.createElement("name");
name.setTextContent("張三");
user.appendChild(name);
//
Element sex = document.createElement("sex");
sex.setTextContent("男");
user.appendChild(sex);
//
root.appendChild(user);
//
TransformerFactory transFactory = TransformerFactory.newInstance();
Transformer transFormer = transFactory.newTransformer();
DOMSource domSource = new DOMSource(document);
//export string
ByteArrayOutputStream bos = new ByteArrayOutputStream();
transFormer.transform(domSource, new StreamResult(bos));
xmlStr = bos.toString();
System.out.println("輸出結果"+xmlStr);
//通過輸出流輸出
File file = new File("D:/out/user.xml");
if(!file.exists()){
file.createNewFile();
}
FileOutputStream out = new FileOutputStream(file);
StreamResult xmlResult = new StreamResult(out);
transFormer.transform(domSource, xmlResult);
}catch(Exception e){
e.printStackTrace();
}
return xmlStr;
}
/*public static void main(String[] args) {
createXML();
}*/
/**
* 轉化xml格式的字串
* <?xml version="1.0" encoding="UTF-8" standalone="no"?>
* <root>
* <user>
* <id>1</id>
* <name>張三</name>
* <sex>男</sex>
* </user>
* </root>
*/
public static List<Map<String,Object>> parseXML(String xmlStr){
List<Map<String,Object>> list=null;
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
try{
DocumentBuilder builder = factory.newDocumentBuilder();
StringReader sr = new StringReader(xmlStr);
InputSource is = new InputSource(sr);
Document doc = builder.parse(is);
//
Element rootElement = doc.getDocumentElement();
//
NodeList users = rootElement.getElementsByTagName("user");
//
list=new ArrayList<Map<String, Object>>();
for(int i=0;i<users.getLength();i++){
Node node = users.item(i);
NodeList childs = node.getChildNodes();
Map<String,Object> map=new HashMap<String, Object>();
for(int j=0;j<childs.getLength();j++){
Node childNode = childs.item(j);
String nodeName=childNode.getNodeName();
String value=childNode.getTextContent();
map.put(nodeName,value);
}
list.add(map);
}
}catch(Exception e){
e.printStackTrace();
}
return list;
}
/*public static void main(String[] args) {
String xmlStr="<?xml version='1.0' encoding='UTF-8' standalone='no'?><root><user><id>1</id><name>張三</name><sex>男</sex></user></root>";
List<Map<String, Object>> list = parseXML(xmlStr);
System.out.println("======"+list.toString());
}*/
}
6，定義一個介面實現類，注意該class的註解。
package com.spring.service;
import javax.jws.WebParam;
import javax.jws.WebService;
/**
*
*/
@WebService
public interface IUser {
//獲取xml格式的資料
/**
* 根據傳遞的條件獲取相簿資訊
* xml的格式規範
* <?xml version="1.0" encoding="UTF-8" standalone="no"?>
* <root>
* <user>
* <id>1</id>
* <name>張三</name>
* <sex>男</sex>
* </user>
* </root>
* 這裡的WebParam必須指定，否則呼叫的時候返回null
* @return
*/
String getUser(@WebParam(name = "xmlStr")String xmlStr);
}
7，實現該介面，注意註解的應用。
package com.spring.service.impl;
import com.spring.service.IUser;
import com.spring.utils.XMLHandler;
import javax.jws.WebService;
import java.util.List;
import java.util.Map;
/**
*
*/
@WebService
public class UserServiceImpl implements IUser {
@Override
public String getUser(String xmlStr) {
List<Map<String, Object>> list = XMLHandler.parseXML(xmlStr);
return list.toString();
}
}
8，main方法測試。
package com.spring.test;
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;
import javax.xml.namespace.QName;
/**
*
*/
public class TestClientCxf {
public static void main(String[] args) throws Exception {
String xmlStr="<?xml version='1.0' encoding='UTF-8' standalone='no'?><root><user><id>1</id><name>張三</name><sex>男</sex></user></root>";
JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
org.apache.cxf.endpoint.Client client = dcf.createClient("http://localhost:8080/cxf/user?wsdl");
//url為呼叫webService的wsdl地址
QName name=new QName("http://service.spring.com/","getUser");
//paramvalue為引數值
Object[] objects=client.invoke(name,xmlStr);
//呼叫web Service//輸出呼叫結果
System.out.println("輸出結果："+objects[0].toString());
/*User user = new User(xmlStr);
Object obj = user.getUser();
System.out.println("========="+obj.toString());*/
}
}
http://localhost:8080/cxf/user?wsdl路徑產生的，cxf的服務端搭建是否成功，需要再瀏覽器訪問一下你的配置路徑，/user 定義在spring-cxf.xml 的配置檔案 <jaxws:endpoint id="userPoint" implementor="#user" address="/user"/>
//url為呼叫webService的wsdl地址
QName name=new QName("http://service.spring.com/","getUser");圖中標註的就是名稱空間，getUser 指的是介面的中定義的方法名稱。
到這裡基本就算結束了，總結的不夠精細，還望擔待。
