Java  web project ( spring Integrated webservice in project To open the interface to the outside world:

Get ready:

Using cxf with good compatibility with spring

The jar download address for cxf: http://cxf.apache.org/download.html

Choose zip format to download, jar in lib directory after decompression

The minimum jar s required are as follows:

One: Create a web service server

1) Create a service interface

package com.service;  
  
import javax.jws.WebParam;  
import javax.jws.WebService;  
  
@WebService  
public interface IHelloWorld {  
    public String sayHello(@WebParam(name = "arg0") String text);  
}  

2) Is an interface implementation class

package com.service.impl;  
  
import javax.jws.WebService;  
  
import com.service.IHelloWorld;  
  
@WebService(endpointInterface = "com.service.IHelloWorld")  
public class HelloWorldImpl implements IHelloWorld {  
    public String sayHello(String text) {  
        return "Hello : " + text;  
    }  
}  

3) Create a spring configuration file to add service classes to the container

webservice.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:p="http://www.springframework.org/schema/p"  
    xmlns:jaxws="http://cxf.apache.org/jaxws"  
    xmlns:cxf="http://cxf.apache.org/core"  
    xsi:schemaLocation="http://www.springframework.org/schema/beans  
    http://www.springframework.org/schema/beans/spring-beans-2.5.xsd  
    http://cxf.apache.org/jaxws  
    http://cxf.apache.org/schemas/jaxws.xsd">  
  
    <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" />  
  
    <!--Below class Property values must exactly match the package path of the service implementation class in your project-->  
    <bean id="hello" class="com.service.impl.HelloWorldImpl"/>  
    <jaxws:endpoint id="helloWorld" implementor="#hello" address="/HelloWorld" />  
</beans>  

Add a webservice.xml configuration file to the web.xml

<context-param>  
    <param-name>contextConfigLocation</param-name>  
    <param-value>  
        /WEB-INF/webservice.xml       
    </param-value>  
</context-param>  

4) Add cxf servlet to web.xml

<servlet>  
    <display-name>CXF Servlet</display-name>  
    <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>/webservice/*</url-pattern>  
</servlet-mapping>  

The webservice server is now created.

Access: http://localhost:8080/test/webservice/HelloWorld?wsdl in a browser (test is the project name).If something similar to

<wsdl:definitions xmlns:ns1="http://service.com/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://impl.service.com/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" name="HelloWorldImplService" targetNamespace="http://impl.service.com/">
. . . . 

Configuration was successful.

Following are a few runtime error resolution tips

1:webservice.xml prompts cxf.xml, cxf-servlet.xml is not found, the path I wrote above is classpath*:META-INF/cxf/cxf.xml, where classpath is followed by a'*'symbol, unsigned means that only the cxf.xml file is found under the class path, plus sign means that not only the XML file is found under the class path, but also under the class pathFind the XML file in the jar package.So if we don't have a configuration file such as cxf.xml under the project class path, we have to append * to the classpath so that the spring container will find it in the jar package we've added.

2: If you do not write a mapping path as /* when using a cxf servlet, otherwise you will not be able to access the project home page, you can write as a request path for a cxf servlet as / webservice/* or a path that has not been used in other projects.

2: Create a web service client

Clients can be used in the same project as servers test Or create a new one Java Project for testing.

When creating a new Java project test, assume that the corresponding jar package, like the server, uses spring and assumes the spring jar package.

I'm creating a new project here and still using spring to test

1) First, create a service interface that is the same as the server side. (You can omit this step if the client and server sides are in the same project.)

package com.service;  
  
import javax.jws.WebParam;  
import javax.jws.WebService;  
  
@WebService  
public interface IHelloWorld {  
    public String sayHello(@WebParam(name = "arg0") String text);  
}  

2) Create spring-client.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:p="http://www.springframework.org/schema/p"  
    xmlns:jaxws="http://cxf.apache.org/jaxws" xmlns:cxf="http://cxf.apache.org/core"  
    xsi:schemaLocation="http://www.springframework.org/schema/beans   
    http://www.springframework.org/schema/beans/spring-beans-2.5.xsd  
    http://cxf.apache.org/jaxws   
    http://cxf.apache.org/schema/jaxws.xsd">  
  
    <bean id="client" class="com.service.IHelloWorld" factory-bean="clientFactory" factory-method="create" />  
    <bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">  
        <property name="serviceClass" value="com.service.IHelloWorld" />  
        <property name="address" value="http://localhost:8080/test/HelloWorld" />  
    </bean>  
</beans>  

3) Test Class

[java] view plain copy

1. package com.test;  
2.   
3. import org.springframework.context.ApplicationContext;  
4. import org.springframework.context.support.ClassPathXmlApplicationContext;  
5.   
6. import com.service.IHelloWorld;  
7.   
8. public class Test {  
9.     public static void main(String[] args) {  
10.         ApplicationContext ctx = new ClassPathXmlApplicationContext("spring-client.xml");  
11.         IHelloWorld client = (IHelloWorld) ctx.getBean("client");  
12. String result = client.sayHello; (Hello!)
13.         System.out.println(result);  
14.     }  
15. }  

Show after successful run

Hello: Hello!
