java cxf webservice 传输文件异常

利用cxf传输大文件会报如下异常,请高手帮忙:

CXF webservice传递复杂对象Map

1. 用cxf写了一个webservice,测试的时候可以传入String,为了传入Map,写了转换类,在Myeclipse10上是可以传Map的,现在项目用的是2014,用maven搭建的,移植的时候发现不能传Map了,求大神指教,下面上图 配置文件 ![图片说明](https://img-ask.csdn.net/upload/201610/26/1477449168_232536.png) service ``` @WebService @SOAPBinding(style=Style.RPC) public interface TestService { public String test(String s); public String sendMap(@XmlJavaTypeAdapter(StringObjectMapAdapter.class) Map<String, Object> data); } ``` 实现类 @WebService @SOAPBinding(style=Style.RPC) public class TestServiceImpl implements TestService { @Override public String test(String s) { return s; } @Override public String sendMap(@XmlJavaTypeAdapter(StringObjectMapAdapter.class) Map<String, Object> data) { return data.toString(); } } ``` ``` 转换类和转换类型类 public class Data { private List<Entry> list = new ArrayList<Entry>(); public void addEntry(String fieldName, Object fieldValue) { Entry entry = new Entry(); entry.setKey(fieldName); entry.setValue(fieldValue); list.add(entry); } public List<Entry> getList() { return list; } public void setList(List<Entry> list) { this.list = list; } public static class Entry { private String key; private Object value; public String getKey() { return key; } public void setKey(String key) { this.key = key; } public Object getValue() { return value; } public void setValue(Object value) { this.value = value; } } } ``` public class StringObjectMapAdapter extends XmlAdapter<Data, Map<String, Object>> { @Override public Map<String, Object> unmarshal(Data data) throws Exception { Map<String, Object> map = new HashMap<String, Object>(); for (Data.Entry entry : data.getList()) { map.put(entry.getKey(), entry.getValue()); } return map; } @Override public Data marshal(Map<String, Object> map) throws Exception { Data data = new Data(); for (Map.Entry<String, Object> entry : map.entrySet()) { data.addEntry(entry.getKey(), entry.getValue()); } return data; } } ``` 客户端测试类 public class ClientTest { public static void main(String[] args) { JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance(); //webservice地址 String path = "http://127.0.0.1:8080/Demo/services/TestService?wsdl"; // 创建客户端连接 Client client = dcf.createClient(path); HTTPConduit http = (HTTPConduit) client.getConduit(); HTTPClientPolicy hcp = new HTTPClientPolicy(); hcp.setConnectionTimeout(2000);//连接超时 hcp.setReceiveTimeout(200000);//请求超时 http.setClient(hcp); Object[] obj = null; Map map = new HashMap<String,Object>(); map.put("a", "111"); try { //将map序列化后调用接口方法 Data map1 = new StringObjectMapAdapter().marshal(map); // obj = client.invoke("sendMap", map1); obj = client.invoke("sendMap", map); } catch (Exception e) { } String returnData = obj[0].toString();//返回的数据串 System.out.println(returnData); } }

java调用webservice接口发送xml报文

1.webservice接口是axis1发布的 2.请求报文格式如下 ``` <?xml version="1.0" encoding="gbk"?><SOAP-ENV:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"> <SOAP-ENV:Header xmlns="http://hwsoft.vms.cn"> <sysID>SW</sysID> <sysPassWord>123456</sysPassWord> <requestTime>2016-01-28</requestTime> <currentPage>1</currentPage> <pageSize>2</pageSize> <totalNum>100</totalNum> </SOAP-ENV:Header> <SOAP-ENV:Body xmlns="http://hwsoft.vms.cn"> <KPRQQ>2015-01-28</KPRQQ> <KPRQZ>2016-01-29</KPRQZ> <RZJG></RZJG> <FPDM></FPDM> <FPHM></FPHM> <FPLX></FPLX> </SOAP-ENV:Body> </SOAP-ENV:Envelope> ``` 如果我要调用这个接口并且严格按照这个格式发送请求,需要用什么方式调用? 求大神给个实例参考。

无代码时代来临,程序员如何保住饭碗?

编程语言层出不穷,从最初的机器语言到如今2500种以上的高级语言,程序员们大呼“学到头秃”。程序员一边面临编程语言不断推陈出新,一边面临由于许多代码已存在,程序员编写新应用程序时存在重复“搬砖”的现象。 无代码/低代码编程应运而生。无代码/低代码是一种创建应用的方法,它可以让开发者使用最少的编码知识来快速开发应用程序。开发者通过图形界面中,可视化建模来组装和配置应用程序。这样一来,开发者直...
