Springboot整合Web service介面服務

1、WebService 是一種跨程式語言和跨作業系統平臺的遠端呼叫技術

2、WebService平臺的三大技術:XML+XSD,SOAP,WSDL。

  1)、XML+XSD:WebService採用HTTP協議傳輸資料,採用XML格式封裝資料(即XML中說明呼叫遠端服務物件的哪個方法,傳遞的引數是什麼,以及服務物件的 返回結果是什麼)。XML是WebService平臺中表示資料的格式。除了易於建立和易於分析外,XML主要的優點在於它既是平臺無關的,又是廠商無關 的。無關性是比技術優越性更重要的:軟體廠商是不會選擇一個由競爭對手所發明的技術的。

  2)、SOAP:WebService通過HTTP協議傳送請求和接收結果時,傳送的請求內容和結果內容都採用XML格式封裝,並增加了一些特定的HTTP訊息頭,以說明 HTTP訊息的內容格式,這些特定的HTTP訊息頭和XML內容格式就是SOAP協議。SOAP提供了標準的RPC方法來呼叫Web Service。SOAP協議 = HTTP協議 + XML資料格式


  3)、WSDL:WebService也一樣,WebService客戶端要呼叫一個WebService服務,首先要有知道這個服務的地址在哪,以及這個服務裡有什麼方 法可以呼叫,所以,WebService務器端首先要通過一個WSDL檔案來說明自己家裡有啥服務可以對外呼叫,服務是什麼(服務中有哪些方法,方法接受 的引數是什麼,返回值是什麼),服務的網路地址用哪個url地址表示,服務通過什麼方式來呼叫。WSDL(Web Services Description Language)就是這樣一個基於XML的語言,用於描述Web Service及其函式、引數和返回值。它是WebService客戶端和伺服器端都 能理解的標準格式。因為是基於XML的,所以WSDL既是機器可閱讀的,又是人可閱讀的,這將是一個很大的好處。一些最新的開發工具既能根據你的 Web service生成WSDL文件,又能匯入WSDL文件,生成呼叫相應WebService的代理類程式碼。

3、這裡使用的是maven依賴,修改pom.xml配置檔案,如下所示:

說明:這裡使用springboot2.1.3或者2.2.4.RELEASE都可以,更高版本未測試。

 1 <?xml version="1.0" encoding="UTF-8"?>

建立一個實體類,使用者資訊的返回和封裝,如下所示:

 1 package com.demo.po;
 2 
 3 import java.io.Serializable;
 4 
 5 public class UserInfo implements Serializable {
 6 
 7     /**
 8      * 
 9      */
10     private static final long serialVersionUID = 1L;
11 
12     private Integer userId;// 使用者編號
13 
14     private String userAccount;// 使用者賬號
15 
16     private String userPw;// 使用者密碼
17 
18     private String userName;// 使用者姓名
19 
20     private Integer userAge;// 使用者年齡
21 
22     private String userSex;// 使用者性別
23 
24     public Integer getUserId() {
25         return userId;
26     }
27 
28     public void setUserId(Integer userId) {
29         this.userId = userId;
30     }
31 
32     public String getUserAccount() {
33         return userAccount;
34     }
35 
36     public void setUserAccount(String userAccount) {
37         this.userAccount = userAccount;
38     }
39 
40     public String getUserPw() {
41         return userPw;
42     }
43 
44     public void setUserPw(String userPw) {
45         this.userPw = userPw;
46     }
47 
48     public String getUserName() {
49         return userName;
50     }
51 
52     public void setUserName(String userName) {
53         this.userName = userName;
54     }
55 
56     public Integer getUserAge() {
57         return userAge;
58     }
59 
60     public void setUserAge(Integer userAge) {
61         this.userAge = userAge;
62     }
63 
64     public String getUserSex() {
65         return userSex;
66     }
67 
68     public void setUserSex(String userSex) {
69         this.userSex = userSex;
70     }
71 
72     @Override
73     public String toString() {
74         return "UserInfo [userId=" + userId + ", userAccount=" + userAccount + ", userPw=" + userPw + ", userName="
75                 + userName + ", userAge=" + userAge + ", userSex=" + userSex + "]";
76     }
77 
78 
79 }

定義Webservice介面,介面需要註解@WebService註解和@WebMethod註解的,如下所示:

 1 package com.demo.service;
 2 
 3 import javax.jws.WebMethod;
 4 import javax.jws.WebParam;
 5 import javax.jws.WebService;
 6 
 7 /**
 8  * 
 9  * @author
10  *
11  */
12 @WebService // 定義介面為一個webservice服務,定義服務,在類上邊,作用在具體類上
13 public interface UserInfoWebService {
14 
15     /**
16      * 定義方法為一個webservice方法
17      *  
18      * @WebParam-定義引數,在方法引數前邊,用於定義wsdl中的引數對映,定製單個引數到web service訊息部分和xml元素的對映關係 
19      *  
20      * @param userId
21      * @return
22      */
23     @WebMethod // 定義方法,在公開方法上邊,此註解用在方法上,用於修改對外暴漏的方法,定製返回值到wsdl部分和xml元素的對映關係
24     public String getUserInfo(@WebParam(name = "userId") String userId);
25 
26 }

定義介面實現類:targetNamespace 的值最好是包名反寫,endpointInterface 是webservice介面的地址,這裡引數配置也可以使用自動生成的,看個人需求的,注意這裡我配置之後報錯了(說明:是因為我配置錯誤,報的錯,但是不影響SoapUI工具呼叫,但是客戶端訪問就報錯了,這裡進行說明一下),所以去掉自定義配置了,讓其自動生成了。

注意給這個類新增@Component直接注入到spring中,或者在配置類中注入bean的方式進行注入到容器中,如下所示:

 1 package com.demo.service.impl;
 2 
 3 import javax.jws.WebService;
 4 
 5 import com.demo.po.UserInfo;
 6 import com.demo.service.UserInfoWebService;
 7 
 8 /**
 9  * 
10  * @author
11  *
12  */
13 // @WebService(
14 // targetNamespace = "http://impl.service.demo.com/",
15 // endpointInterface = "com.demo.service.impl.UserInfoWebServiceImpl")
16 @WebService
17 public class UserInfoWebServiceImpl implements UserInfoWebService {
18 
19     @Override
20     public UserInfo getUserInfo(Integer userId) {
21         System.out.println("---------------------------------userId--------------------------- : " + userId);
22         UserInfo userInfo = new UserInfo();
23         userInfo.setUserId(userId);
24         userInfo.setUserAccount("張姍姍");
25         userInfo.setUserPw("123456");
26         userInfo.setUserAge(26);
27         userInfo.setUserSex("");
28         userInfo.setUserName("張姍姍");
29         return userInfo;
30     }
31 
32 }

定義Web service介面服務的配置類:該類的作用是將改Web service服務以userInfoWebService的名稱釋出出去,如下所示:

 1 package com.demo.config;
 2 
 3 import javax.xml.ws.Endpoint;
 4 
 5 import org.apache.cxf.Bus;
 6 import org.apache.cxf.bus.spring.SpringBus;
 7 import org.apache.cxf.jaxws.EndpointImpl;
 8 import org.apache.cxf.transport.servlet.CXFServlet;
 9 import org.springframework.boot.web.servlet.ServletRegistrationBean;
10 import org.springframework.context.annotation.Bean;
11 import org.springframework.context.annotation.Configuration;
12 
13 import com.demo.service.UserInfoWebService;
14 import com.demo.service.impl.UserInfoWebServiceImpl;
15 
16 /**
17  * 
18  * @author
19  *
20  */
21 @Configuration
22 public class WebServiceConfig {
23 
24     @Bean(name = "cxfServlet")  // 注入servlet bean name不能dispatcherServlet ,否則會覆蓋dispatcherServlet
25     public ServletRegistrationBean<CXFServlet> cxfServlet() {
26         return new ServletRegistrationBean<CXFServlet>(new CXFServlet(), "/webservice/*");
27     }
28 
29     @Bean
30     public UserInfoWebService userInfoWebService() {
31         return new UserInfoWebServiceImpl();
32     }
33 
34     @Bean(name = Bus.DEFAULT_BUS_ID)
35     public SpringBus springBus() {
36         return new SpringBus();
37     }
38 
39     @Bean
40     public Endpoint endpoint() {
41         // 引數二,是SEI實現類物件
42         EndpointImpl endpoint = new EndpointImpl(this.springBus(), this.userInfoWebService());
43         // 釋出服務
44         endpoint.publish("/userListService");
45         return endpoint;
46     }
47 
48 }

在瀏覽器輸入http://localhost:8080/webservice/userListService?wsdl,如下所示:

在將Springboot和CXF整合之後,如果沒有在配置類中配置ServletRegistrationBean的話,訪問地址是無法獲取到wsdl的穩定的,解決辦法就是new ServletRegistrationBean<CXFServlet>(new CXFServlet(), "/webservice/*");注入一個bean。

使用SoapUI工具或者自己編寫客戶端去測試服務介面,這裡先使用SoapUI工具進行測試,稍後自己編寫客戶端進行呼叫測試,如下所示:

SoapUI工具安裝參考https://www.cnblogs.com/Sweettesting/p/11399534.html,我這裡使用的還是5.1.2版本,有的使用的是5.3.0版本的,介面略有不通。

SoapUI工具使用教程參考:https://blog.csdn.net/w0002399/article/details/82051404

這裡可以選擇使用上面的xml介面或者使用下面的表單介面都可以,看個人需求,效果如下所示:

4、如何進行客戶端訪問呢,簡單的客戶端訪問,動態呼叫的方式,缺點是隻能返回Object物件,如下所示:

 1 package com.demo.utils;
 2 
 3 import org.apache.cxf.endpoint.Client;
 4 import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;
 5 
 6 public class WebServiceClient {
 7 
 8     public static void main(String[] args) {
 9         // 代理工廠
10         JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
11         // 介面地址,這裡如果是不是本公司的,需要將wsdl下載到本地的專案中,然後引用本地的哦
12         Client client = dcf.createClient("http://localhost:8080/webservice/userListService?wsdl");
13         // 可以在此處配置入攔截器或者出攔截器
14         // client.getOutInterceptors().add(new ClientLoginInterceptor(USER_NAME,PASS_WORD));
15         Object[] objects = new Object[0];
16         try {
17             // invoke("方法名",引數1,引數2,引數3....);
18             // 切記invoke的第一個引數是方法的名稱,第二個引數是一個可變引數
19             objects = client.invoke("getUserInfo", 1);
20             System.out.println("返回資料:" + objects[0]);
21         } catch (java.lang.Exception e) {
22             e.printStackTrace();
23         }
24     }
25 
26 }

此時,如果啟動專案,會報下面的錯誤,解決方法就是右擊專案,Properties,然後找到Java Build Path,使用jdk的環境即可,如果使用jre的環境就會報下面的錯誤:

修改完jdk的環境之後,如果啟動客戶端訪問,就會報下面的錯誤,這裡就需要注意了,

解決方案:@WebService(targetNamespace = "http://service.demo.com/", endpointInterface = "com.demo.service.impl.UserInfoWebService")。

  這個註解裡面targetNamespace是一定要寫的,這是指名我們暴露出去的介面在哪,不寫對映不到,就會報No operation was found with the name {http://impl.service.demo.com/}getUserInfo.這個錯誤 ,請注意targetNamespace最後面有一個斜線。endpointInterface="com.demo.service.impl.UserInfoWebService" 這個是告訴介面是那個,不配置也報錯。

17 public class UserInfoWebServiceImpl implements UserInfoWebService {
18 
19     @Override
20     public UserInfo getUserInfo(Integer userId) {
21         System.out.println("---------------------------------userId--------------------------- : " + userId);
22         UserInfo userInfo = new UserInfo();
23         userInfo.setUserId(userId);
24         userInfo.setUserAccount("張姍姍");
25         userInfo.setUserPw("123456");
26         userInfo.setUserAge(26);
27         userInfo.setUserSex("");
28         userInfo.setUserName("張姍姍");
29         return userInfo;
30     }
31 
32 }

5、下面使用代理類工廠的方式,獲取到自己的物件,進行呼叫,返回自己需要的內容,如下所示:

 1 package com.demo.utils;
 2 
 3 import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
 4 
 5 import com.demo.po.UserInfo;
 6 import com.demo.service.UserInfoWebService;
 7 
 8 public class WebServiceClient {
 9 
10     public static void main(String[] args) {
11         try {
12             // 介面地址
13             String address = "http://localhost:8080/webservice/userListService?wsdl";
14             // 代理工廠
15             JaxWsProxyFactoryBean jaxWsProxyFactoryBean = new JaxWsProxyFactoryBean();
16             // 設定代理地址
17             jaxWsProxyFactoryBean.setAddress(address);
18             // 設定介面型別
19             jaxWsProxyFactoryBean.setServiceClass(UserInfoWebService.class);
20             // 建立一個代理介面實現
21             UserInfoWebService userInfoWebService = (UserInfoWebService) jaxWsProxyFactoryBean.create();
22             // 資料準備
23             Integer userId = 1;
24             // 呼叫代理介面的方法呼叫並返回結果
25             UserInfo userInfo = userInfoWebService.getUserInfo(userId);
26             System.out.println("返回結果: " + userInfo);
27         } catch (Exception e) {
28             e.printStackTrace();
29         }
30     }
31 
32 }

返回結果,如下所示:
