初入WebService

1. 搭建webservice需要用到的jar

2. applicationContext.xml配置文件

   <?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:aop="http://www.springframework.org/schema/aop"
   	xmlns:cxf="http://cxf.apache.org/core" xmlns:jaxws="http://cxf.apache.org/jaxws"
   	xmlns:jaxrs="http://cxf.apache.org/jaxrs"
   
   	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
   	http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.xsd
   	http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">
   
   	<jaxrs:server id="employeeServiceServer" address="/employeeservice">
   		<jaxrs:serviceBeans>
   			<ref bean="employeeService" />
   		</jaxrs:serviceBeans>
   		<jaxrs:providers>
   			<bean class="org.codehaus.jackson.jaxrs.JacksonJsonProvider" />
   		</jaxrs:providers>
   	</jaxrs:server>
   
   	<bean id="employeeService" class="service.EmployeeService" />
   </beans>
   

   　　

3. Web.xml配置

   <?xml version="1.0" encoding="UTF-8"?>
   <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
     <display-name>employee-service</display-name>
   
   <context-param>
   	<param-name>contextConfigLocation</param-name>
   	<param-value>/WEB-INF/applicationContext.xml</param-value>
   </context-param>
   <listener>
   <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
   </listener>
   
       <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>/services/*</url-pattern>
       </servlet-mapping>
     <welcome-file-list>
       <welcome-file>index.html</welcome-file>
       <welcome-file>index.htm</welcome-file>
       <welcome-file>index.jsp</welcome-file>
       <welcome-file>default.html</welcome-file>
       <welcome-file>default.htm</welcome-file>
       <welcome-file>default.jsp</welcome-file>
     </welcome-file-list>
   </web-app>
   

   　　

4. model/employee.java

   package model;
   
   import java.io.Serializable;
   
   public class Employee implements Serializable
   {
       /**
   	 *
   	 */
   	private static final long serialVersionUID = 5954986571237608774L;
   	private String id;
       private String code;
       private String name;
   
       public String getId()
       {
           return id;
       }
   
       public void setId(String id)
       {
           this.id = id;
       }
   
       public String getCode()
       {
           return code;
       }
   
       public void setCode(String code)
       {
           this.code = code;
       }
   
       public String getName()
       {
           return name;
       }
   
       public void setName(String name)
       {
           this.name = name;
       }
   
   	@Override
   	public String toString() {
   		return "Employee [code=" + code + ", id=" + id + ", name=" + name + "]";
   	}
   
   }
   

5. service/employeeservice.java

   package service;
   
   import java.util.ArrayList;
   import java.util.List;
   
   import javax.ws.rs.Consumes;
   import javax.ws.rs.GET;
   import javax.ws.rs.Path;
   import javax.ws.rs.Produces;
   
   import model.Employee;
   
   public class  EmployeeService {
   
   	@GET
       @Path("/employees")
       @Consumes("application/json")
       @Produces("application/json")
   	public List<Employee> findallEmployee(){
   		return initData();
   	}
   
   	public List<Employee> initData(){
   		List<Employee> list = new ArrayList<Employee>();
   		for(int i=0;i<10;i++){
   			Employee emp = new Employee();
   			emp.setId("id"+i);
   			emp.setName("员工"+i);
   			emp.setCode("code"+i);
   			list.add(emp);
   		}
   		return list;
   	}
   
   	public static void main(String[] args) {
   		EmployeeService a = new EmployeeService();
   		for(Employee e:a.findallEmployee()){
   			System.out.println(e);
   		}
   	}
   
   }
