webservice 动态调用使用技巧
参考使用
- maven 引用
<dependency>

- 代码
JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
Client client = dcf.createClient("echo.wsdl");
Object[] res = client.invoke("echo", "test echo");
System.out.println("Echo response: " + res[0]);
常见问题
- org.apache.cxf.interceptor.Fault: Unmarshalling Error: unexpected element
忽略错误即可 但是需要注意实际是否需要进行数据校验(以下代码同时添加了一个client 的cache 处理)
public class WsClient {
private static final Logger logger = LoggerFactory.getLogger(WsClient.class);
private static final Cache<String, Client> cache = Caffeine.newBuilder()
.expireAfterAccess(10, TimeUnit.MINUTES)
.maximumSize(10_000)
.build();
public static Client createClient(String endpoint) {
logger.info("create ws client:{}",endpoint);
Client client = JaxWsDynamicClientFactory.newInstance().createClient(endpoint + "?wsdl");
// ignore validation-event-handler fix https://access.redhat.com/solutions/2047853
client.getRequestContext().put("set-jaxb-validation-event-handler", false);
return client;
}
public static Client getClient(String endpoint) {
return cache.get(endpoint,wsURL->createClient(wsURL));
}
}
说明
JaxWsDynamicClientFactory 内部是比较复杂了，使用了动态代码编译以及类加载机制，可以简化我们很多ws 调用的处理
