JDKWebservice publishing is already built in, but to publish Web services with Web servers such as Tomcat, you need a third-party Web service framework. Axis2 and CXF are the most popular Webservice frameworks at present, these twoA framework has its own advantages, but they are all heavyweight frameworks. JAX-WS RI is a reference implementation of JAX WebService. Compared to Axis2 and CXF, JAX-WS RI is a lightweight framework. Although it’s a lightweight framework, JAX-WS RIIt also provides the function of publishing Webservice in Web server. Official website address https://jax-ws.java.net/. Next, use JAX-WS RI to publish WebService in Tomcat.
Server-side
1、Create a new Maven Web project, add JAX-WS RI reference to the project, and the pom.xml configuration file is as follows:

1 <?xml version="1.0" encoding="UTF-8"?> 2 <project xmlns="http://maven.apache.org/POM/4.0.0" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> 5 <modelVersion>4.0.0</modelVersion> 6 7 <groupId>top.jimc</groupId> 8 <artifactId>wsi</artifactId> 9 <version>1.0-SNAPSHOT</version> 10 <packaging>war</packaging> 11 12 <properties> 13 <junit.version>4.12</junit.version> 14 <jaxws-rt.version>2.2.10</jaxws-rt.version> 15 </properties> 16 17 <dependencies> 18 <!-- junit --> 19 <dependency> 20 <groupId>junit</groupId> 21 <artifactId>junit</artifactId> 22 <version>${junit.version}</version> 23 <scope>test</scope> 24 </dependency> 25 26 <!-- JAXWS-RI --> 27 <dependency> 28 <groupId>com.sun.xml.ws</groupId> 29 <artifactId>jaxws-rt</artifactId> 30 <version>${jaxws-rt.version}</version> 31 </dependency> 32 </dependencies> 33 34 <build> 35 <plugins> 36 <!-- Configure plug-ins that control JDK version--> 37 <plugin> 38 <groupId>org.apache.maven.plugins</groupId> 39 <artifactId>maven-compiler-plugin</artifactId> 40 <version>3.7.0</version> 41 <configuration> 42 <source>1.8</source> 43 <target>1.8</target> 44 <encoding>utf-8</encoding> 45 </configuration> 46 </plugin> 47 </plugins> 48 </build> 49 50 </project>

2、Create service interface:

1 package top.jimc.wsi.api; 2 3 import top.jimc.wsi.entity.Person; 4 5 import javax.jws.WebService; 6 import java.util.Date; 7 8 /** 9 * WebServiceInterface10 * @author Jimc. 11 * @since 2018/8/31. 12 */ 13 @WebService(name = "helloWSoap", targetNamespace = "http://wsi.jimc.top/api/hello") 14 public interface HelloWService { 15 16 /** 17 * Add two integers.18 * 19 * @param x 20 * @param y 21 * @return Added value22 */ 23 Integer add(Integer x, Integer y); 24 25 /** 26 * Return to the current time27 * 28 * @return 29 */ 30 Date now(); 31 32 /** 33 * Getting complex types34 * @param name User name35 * @param age User age36 * @return Return to user class37 */ 38 Person getPerson(String name, Integer age); 39 40 }
View Code
3、Complex type (entity) Person used in services:

1 package top.jimc.wsi.entity; 2 3 import java.io.Serializable; 4 5 /** 6 * @author Jimc. 7 * @since 2018/8/31. 8 */ 9 public class Person implements Serializable { 10 private static final long serialVersionUID = -7211227224542440039L; 11 12 private String name; 13 private Integer age; 14 15 public String getName() { 16 return name; 17 } 18 public void setName(String name) { 19 this.name = name; 20 } 21 public Integer getAge() { 22 return age; 23 } 24 public void setAge(Integer age) { 25 this.age = age; 26 } 27 }
View Code
4、Create a service interface implementation class:

1 package top.jimc.wsi.api.impl; 2 3 import top.jimc.wsi.api.HelloWService; 4 import top.jimc.wsi.entity.Person; 5 6 import javax.jws.WebService; 7 import java.util.Date; 8 9 /** 10 * WebServiceInterface implementation11 * @author Jimc. 12 * @since 2018/8/31. 13 */ 14 @WebService(endpointInterface = "top.jimc.wsi.api.HelloWService", 15 portName = "HelloWSoap", 16 serviceName = "HelloWService", 17 targetNamespace = "http://wsi.jimc.top/api/hello") 18 public class HelloWServiceImpl implements HelloWService { 19 20 @Override 21 public Integer add(Integer x, Integer y) { 22 return x + y; 23 } 24 25 @Override 26 public Date now() { 27 return new Date(); 28 } 29 30 @Override 31 public Person getPerson(String name, Integer age) { 32 Person person = new Person(); 33 person.setName(name); 34 person.setAge(age); 35 return person; 36 } 37 }

5、Create the WebService configuration file sun-jaxws.xml in WEB-INF, where one WebService corresponds to an Endpoint:

1 <?xml version="1.0" encoding="UTF-8"?> 2 <endpoints xmlns="http://java.sun.com/xml/ns/jax-ws/ri/runtime" version="2.0"> 3 <endpoint name="hello" implementation="top.jimc.wsi.api.impl.HelloWServiceImpl" url-pattern="/api/hello"/> 4 </endpoints>
View Code
6、Add WSServlet to web.xml. If the Web project uses Servlet 3, it does not need the following configuration:

1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" 5 version="3.1"> 6 7 <!-- Servlet 3.0Or no configuration is required.--> 8 <servlet> 9 <servlet-name>jaxws</servlet-name> 10 <servlet-class>com.sun.xml.ws.transport.http.servlet.WSServlet</servlet-class> 11 <load-on-startup>1</load-on-startup> 12 </servlet> 13 <servlet-mapping> 14 <servlet-name>jaxws</servlet-name> 15 <url-pattern>/api/hello</url-pattern> 16 </servlet-mapping> 17 </web-app>

7、Start Tomcat to see the effect:
Address bar input: http://localhost:8080/api/hello? WSDL
The above image shows that the interface has been successfully released.

2、The Java class is generated and the generated class is added to the corresponding package of the client:
wsimport -encoding utf-8 -p top.jimc.wst -s E:\Code\Projects\wsp\wst\src\main\java http://localhost:8080/api/hello?wsdl
3、Call interface
