Spring发布WebService(CXF)

CXF可以发布的SOAP Service 和 RESTful Service。

一、SOAP Service

1.引入jar包

<dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-frontend-jaxws</artifactId>
            <version>3.1.6</version>
        </dependency>
        
        <!-- https://mvnrepository.com/artifact/org.apache.cxf/cxf-core -->
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-core</artifactId>
            <version>3.1.6</version>
        </dependency>
        
        <!-- https://mvnrepository.com/artifact/org.apache.cxf/cxf-rt-transports-http -->
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-transports-http</artifactId>
            <version>3.1.6</version>
        </dependency>

2.配置web.xml

<!-- Spring和mybatis的配置文件,Spring和CXF的配置 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring-cxf.xml</param-value>
	</context-param>
	
	<!--定义一个cxf的servlet-->
    <servlet>
        <servlet-name>CXFServlet</servlet-name>
        <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
    </servlet>
    
    <servlet-mapping>
        <servlet-name>CXFServlet</servlet-name>
        <url-pattern>/webservice/*</url-pattern>
    </servlet-mapping>

3.编写接口

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService
public interface SayHelloService {
	
	@WebMethod
	public String SayHello(String name);
}

4.实现接口

import javax.jws.WebService;

import com.it.service.SayHelloService;

@WebService(endpointInterface="com.it.service.SayHelloService")
public class SayHelloServiceImpl implements SayHelloService {
	
	public String SayHello(String name) {
		return "你好"+name;
	}
}

5.配置spring-cxf.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/beans
	    http://www.springframework.org/schema/beans/spring-beans.xsd
        http://cxf.apache.org/jaxws 
        http://cxf.apache.org/schemas/jaxws.xsd">
  <!-- 引cxf的一些核心配置 -->
  <import resource="classpath:META-INF/cxf/cxf.xml"/>
  
  <jaxws:endpoint 
  id="SayHelloService" 
  implementor="com.it.service.impl.SayHelloServiceImpl" 
  address="/SayHelloService"/>
</beans>

6.访问http://ip:port/项目/webservice可以看到SOAP Service，就说明成功了。

二、RESTful Service

1.引入jar包(在上面的基础之上添加)

<dependency>
	       <groupId>org.apache.cxf</groupId>
	       <artifactId>cxf-rt-frontend-jaxrs</artifactId>
	       <version>3.1.6</version>
       </dependency>

	   <!-- CXF jaxrs description 依赖 -->
	   <dependency>
	       <groupId>org.apache.cxf</groupId>
	       <artifactId>cxf-rt-rs-service-description</artifactId>
	       <version>3.1.6</version>
	   </dependency>

2. 配置web.xml

<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring-cxf.xml,classpath:spring-cxf2.xml</param-value>
	</context-param>

3. 编写接口

public interface TestRestService {
    public String sayHello( String userName);
}

4.实现接口

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

import org.springframework.stereotype.Component;

import com.it.service.SayHelloService;

@Component
@Path("/test")
public class TestRestServiceImpl implements SayHelloService {

	@GET
	@Path("/hello/{username}")
    //@Produces({ MediaType.APPLICATION_XML })
	public String SayHello(@PathParam("username") String name) {
		String rs = "你好"+name;
		System.out.println(rs);
		return rs;
	}
}

5. 配置spring-cxf2.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:jaxrs="http://cxf.apache.org/jaxrs"
   xsi:schemaLocation="http://www.springframework.org/schema/beans
	    http://www.springframework.org/schema/beans/spring-beans.xsd
        http://cxf.apache.org/jaxrs
        http://cxf.apache.org/schemas/jaxrs.xsd
        ">
  <!-- 引cxf的一些核心配置 -->
  <import resource="classpath:META-INF/cxf/cxf.xml"/>
  
  <jaxrs:server id="TestRestService" address="/TestRestService">
        <jaxrs:serviceBeans>
          <ref bean="testRestServiceImpl" />
        </jaxrs:serviceBeans>
  </jaxrs:server>
</beans>

6. 访问 http://ip:port/项目/webservice可以看到RESTful Service，就说明成功了。

7.RESTful Service 可以这么使用http://ip:port/项目名/webservice/{address}/{path...}/{参数...}

如：http://127.0.0.1/SSM/webservice/TestRestService/test/hello/superman

三、访问地址中的webservice是在web.xml里进行配置的。具体位置如下。

<servlet-mapping>

        <servlet-name>CXFServlet</servlet-name>
        <url-pattern>/webservice/*</url-pattern>
    </servlet-mapping>
