WebService学习总结九 使用Spring发布WebService

服务端WebService接口使用Spring发布，客户端使用java测试。

服务端：

导入对应的jar包，编写服务接口并实现，和之前方式相同，然后在src下加个配置文件，引入cxf的核心配置。在web.xml引入这个配置文件，开启spring监听，引入CXFServlet处理请求。

package ws.spring.server;

public class UserBean {
	private int id;
	private String name;
	
	public UserBean(int id, String name) {
		super();
		this.id = id;
		this.name = name;
	}
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	@Override
	public String toString() {
		return "UserBean [id=" + id + ", name=" + name + "]";
	}
	
}

package ws.spring.server;

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

@WebService
public interface UserWS {
	@WebMethod
	public UserBean getUserById(int id);
}

package ws.spring.server;

import javax.jws.WebService;

@WebService
public class UserWSImpl implements UserWS {
	public UserWSImpl(){
		System.out.println("初始化 UserWSImpl");
	}
	@Override
	public UserBean getUserById(int id) {
		System.out.println("server getUserById:"+id);
		return new UserBean(1, "张三");
	
	}

}

beans.xml

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

   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  </servlet>
  <servlet-mapping>
    <servlet-name>CXFServlet</servlet-name>
    <url-pattern>/*</url-pattern>
  </servlet-mapping>
</web-app>

客户端：

导入jar包，生成客户端代码，在src下引入配置文件，编写测试类。

生成的客户端代码：

GetUserById.java
GetUserByIdResponse.java
ObjectFactory.java
package-info.java
UserBean.java
UserWS.java
UserWSImplService.java

配置文件：

client-beans.xml

测试代码：

package ws.spring.server;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestClient {

	public static void main(String[] args) {
		ClassPathXmlApplicationContext context=new ClassPathXmlApplicationContext(
				new String[]{"client-beans.xml"});
		UserWS userWS=(UserWS) context.getBean("userClient");
		UserBean userBean=userWS.getUserById(2);
		System.out.println("Client:"+userBean);
	}

}

有个问题：

如果在ws_spring_server项目里，加个jsp页面，当你用http://localhost:8080/ws_spring_server/index.jsp进行访问的时候，会报错：找不到index.jsp的Observer,

问题在于web.xml的配置：

  <servlet>
    <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>/*</url-pattern>
  </servlet-mapping>

/*说明任何请求，都会使用CXFServlet处理，而我们访问index.jsp也使用这个Servlet进行了处理，这样显然不合理。把/*修改为：/WS/*,就可以了加以区分了。WS可以改为任意名称，如/WebService/*.

访问wsdl的时候也需要修改路径，前面加上对应的前缀：如果改为了/WS/*,访问wsdl路径变成了：

http://localhost:8080/ws_spring_server/WS/userws?wsdl。注意：beans.xml不需要做任何修改。

对应的客户端代码的配置需要跟/WS/*，修改为：

address= "http://localhost:8080/ws_spring_server/WS/userws">

前面也加上对应的WS.
