ofbiz的服务(service)export成web service的方法(8)

返回参数为多种数据类型的AXIS处理

假设写如下一个ofbiz的服务：

1.      <service name="findPersonByPartyId" engine="java"
2.             location="org.ofbiz.party.party.TestParty" invoke="findPersonByPartyId" auth="false" export="true">
3.         <description>test</description>
4.         <attribute name="partyId" type="String" mode="INOUT" optional="false"/>
5.         <attribute name="firstName" type="String" mode="OUT" optional="false"/>
6.         <attribute name="lastName" type="String" mode="OUT" optional="false"/>
7.         <attribute name="salary" type="Double" mode="OUT" optional="false"/>
8.     </service>

这个服务中的返回参数有string和double两种数据类型，实现的代码如下：

1. public static Map findPersonByPartyId(DispatchContext dctx, Map context) {
2.         GenericDelegator delegator = dctx.getDelegator();
3.         String partyId = (String)context.get("partyId");
4.         Map result = new HashMap();
5.                         
6.         try{
7.             GenericValue person = delegator.findByPrimaryKey("Person", UtilMisc.toMap("partyId", partyId));
8.             String firstName = (String)person.get("firstName");
9.             String lastName = (String)person.get("lastName");
10.             
11.             result.put("partyId",partyId);
12.             result.put("firstName", firstName);
13.             result.put("lastName",lastName);
14.             result.put("salary", new Double(1.12));
15.             
16.         }catch(GenericEntityException e){
17.             return ServiceUtil.returnError("partyId #" + partyId + "not found!");
18.         }                
19.         return result;
20.     }

编译发布后，客户端调用如下：

2. import java.util.*;
3. import java.net.*;

54.                 
55.         System.out.println(partyId + ":" + firstName + " " + lastName + "'s salary is " + salary);
57.     } catch (MalformedURLException ex) {

68. }     

如此而已……
