今天在學習Web Service的時候得知Amazon提供了一個搜索的Web Service,于是考慮寫一個方法訪問一下看看..
Amazon Web Service 的WSDL:
http://soap.amazon.com/schemas2/AmazonWebServices.wsdl得到了WSDL以后,在命令行執行:
java org.apache.axis.wsdl.WSDL2Java
http://soap.amazon.com/schemas2/AmazonWebServices.wsdl就會在%AXIS_HOME%目錄下生成一個包結構:com.amazon.soap.*;里面有很多包,不過如果看了上面那個wsdl的話應該知道主要的類是
AmazonSearchService和AmazonSearchPort,前面是服務,后面是調用方法的對象..
AmazonSearchService:
public?interface?AmazonSearchService?extends?javax.xml.rpc.Service?
{
????public?java.lang.String?getAmazonSearchPortAddress();
????public?com.amazon.soap.AmazonSearchPort?getAmazonSearchPort()?throws?javax.xml.rpc.ServiceException;
????public?com.amazon.soap.AmazonSearchPort?getAmazonSearchPort(java.net.URL?portAddress)?throws?javax.xml.rpc.ServiceException;
}AmazonSearchPort:
package?com.amazon.soap;
public?interface?AmazonSearchPort?extends?java.rmi.Remote?{
????public?com.amazon.soap.ProductInfo?keywordSearchRequest(com.amazon.soap.KeywordRequest?keywordSearchRequest)?throws?java.rmi.RemoteException;
????public?com.amazon.soap.ProductInfo?powerSearchRequest(com.amazon.soap.PowerRequest?powerSearchRequest)?throws?java.rmi.RemoteException;
????public?com.amazon.soap.ProductInfo?browseNodeSearchRequest(com.amazon.soap.BrowseNodeRequest?browseNodeSearchRequest)?throws?java.rmi.RemoteException;
????public?com.amazon.soap.ProductInfo?asinSearchRequest(com.amazon.soap.AsinRequest?asinSearchRequest)?throws?java.rmi.RemoteException;
????public?com.amazon.soap.ProductLine[]?blendedSearchRequest(com.amazon.soap.BlendedRequest?blendedSearchRequest)?throws?java.rmi.RemoteException;
????public?com.amazon.soap.ProductInfo?upcSearchRequest(com.amazon.soap.UpcRequest?upcSearchRequest)?throws?java.rmi.RemoteException;
????public?com.amazon.soap.ProductInfo?authorSearchRequest(com.amazon.soap.AuthorRequest?authorSearchRequest)?throws?java.rmi.RemoteException;
????public?com.amazon.soap.ProductInfo?artistSearchRequest(com.amazon.soap.ArtistRequest?artistSearchRequest)?throws?java.rmi.RemoteException;
????public?com.amazon.soap.ProductInfo?actorSearchRequest(com.amazon.soap.ActorRequest?actorSearchRequest)?throws?java.rmi.RemoteException;
????public?com.amazon.soap.ProductInfo?manufacturerSearchRequest(com.amazon.soap.ManufacturerRequest?manufacturerSearchRequest)?throws?java.rmi.RemoteException;
????public?com.amazon.soap.ProductInfo?directorSearchRequest(com.amazon.soap.DirectorRequest?directorSearchRequest)?throws?java.rmi.RemoteException;
????public?com.amazon.soap.ProductInfo?listManiaSearchRequest(com.amazon.soap.ListManiaRequest?listManiaSearchRequest)?throws?java.rmi.RemoteException;
????public?com.amazon.soap.ProductInfo?wishlistSearchRequest(com.amazon.soap.WishlistRequest?wishlistSearchRequest)?throws?java.rmi.RemoteException;
????public?com.amazon.soap.ListingProductDetails?exchangeSearchRequest(com.amazon.soap.ExchangeRequest?exchangeSearchRequest)?throws?java.rmi.RemoteException;
????public?com.amazon.soap.MarketplaceSearch?marketplaceSearchRequest(com.amazon.soap.MarketplaceRequest?marketplaceSearchRequest)?throws?java.rmi.RemoteException;
????public?com.amazon.soap.SellerProfile?sellerProfileSearchRequest(com.amazon.soap.SellerProfileRequest?sellerProfileSearchRequest)?throws?java.rmi.RemoteException;
????public?com.amazon.soap.SellerSearch?sellerSearchRequest(com.amazon.soap.SellerRequest?sellerSearchRequest)?throws?java.rmi.RemoteException;
????public?com.amazon.soap.ProductInfo?similaritySearchRequest(com.amazon.soap.SimilarityRequest?similaritySearchRequest)?throws?java.rmi.RemoteException;
????public?com.amazon.soap.ShoppingCart?getShoppingCartRequest(com.amazon.soap.GetShoppingCartRequest?getShoppingCartRequest)?throws?java.rmi.RemoteException;
????public?com.amazon.soap.ShoppingCart?clearShoppingCartRequest(com.amazon.soap.ClearShoppingCartRequest?clearShoppingCartRequest)?throws?java.rmi.RemoteException;
????public?com.amazon.soap.ShoppingCart?addShoppingCartItemsRequest(com.amazon.soap.AddShoppingCartItemsRequest?addShoppingCartItemsRequest)?throws?java.rmi.RemoteException;
????public?com.amazon.soap.ShoppingCart?removeShoppingCartItemsRequest(com.amazon.soap.RemoveShoppingCartItemsRequest?removeShoppingCartItemsRequest)?throws?java.rmi.RemoteException;
????public?com.amazon.soap.ShoppingCart?modifyShoppingCartItemsRequest(com.amazon.soap.ModifyShoppingCartItemsRequest?modifyShoppingCartItemsRequest)?throws?java.rmi.RemoteException;
}
我打算調用keywordSearchRequest這個方法,這個方法有一個keywordRequest參數,返回一個ProductInfo對象
public?com.amazon.soap.ProductInfo?keywordSearchRequest(com.amazon.soap.KeywordRequest?keywordSearchRequest)?throws?java.rmi.RemoteException;
下面是調用Web Service的類:
/**?*//**

package?org.zsu.zouang;
import?java.rmi.RemoteException;
import?javax.xml.rpc.ServiceException;
import?com.amazon.soap.AmazonSearchPort;
import?com.amazon.soap.AmazonSearchServiceLocator;
import?com.amazon.soap.Details;
import?com.amazon.soap.KeywordRequest;
import?com.amazon.soap.ProductInfo;
/**?*//**

public?class?MyAmazonClient?{
????/**?*//**

????public?static?void?main(String[]?args)?{
????????KeywordRequest?keyword?=?new?KeywordRequest();
????????keyword.setKeyword("Java");
????????keyword.setMode("books");
????????keyword.setTag("D3HW0PG66IPLAM");
????????keyword.setDevtag("D3HW0PG66IPLAM");
????????keyword.setPage("1");
????????keyword.setType("heavy");
????????keyword.setSort(null);
????????keyword.setVariations(null);
????????keyword.setLocale(null);
????????//?TODO?Auto-generated?method?stub
????????try?{
????????????AmazonSearchPort?port?=?new?AmazonSearchServiceLocator().getAmazonSearchPort();
????????????ProductInfo?info?=?port.keywordSearchRequest(keyword);
????????????System.out.println("Number?of?Results?:"?+?info.getTotalResults());
????????????Details[]?details?=?info.getDetails();
????????????for(Details?d?:?details){
????????????????System.out.println("ISBN?:"?+?d.getIsbn()?+?"?Name:"?+?d.getProductName());
????????????}
????????}?catch?(RemoteException?e)?{
????????????//?TODO?Auto-generated?catch?block
????????????e.printStackTrace();
????????}?catch?(ServiceException?e)?{
????????????//?TODO?Auto-generated?catch?block
????????????e.printStackTrace();
????????}
????}
} 返回的結果:
-?Unable?to?find?required?classes?(javax.activation.DataHandler?and?javax.mail.internet.MimeMultipart).?Attachment?support?is?disabled.
