Question

我有一些非常基本的代码来调用webservice。使用RestTemplate（）。getForObject为我提供“不是有效的HTTP URL”错误。

Exception in thread "main" java.lang.IllegalArgumentException:         [localhost:9080/someApp/testWs/partners/1] is not a valid HTTP URL
at org.springframework.web.util.UriUtils.encodeHttpUrl(UriUtils.java:245)
at org.springframework.web.client.RestTemplate$HttpUrlTemplate.encodeUri(RestTemplate.java:651)
at org.springframework.web.util.UriTemplate.expand(UriTemplate.java:140)
at org.springframework.web.client.RestTemplate.execute(RestTemplate.java:400)
at org.springframework.web.client.RestTemplate.getForObject(RestTemplate.java:199)
at org.kofc.test.TestTemplate.main(TestTemplate.java:26)

以下是客户端代码：

package org.smpkg.test;

import org.smpkg.dvo.Prtnr;
import org.springframework.web.client.RestTemplate;

public class TestTemplate 
{

    private static final long serialVersionUID = 1130201273334264152L;
    public static void main(String[] args){
        System.out.println("I am here ....");
        Prtnr partner = new RestTemplate().getForObject("localhost:9080/someApp/testWs/partners/{id}", Prtnr.class, "1");
        System.out.println("partner name is : " + partner.getPrtnrNm());
    }
}

控制器

@RequestMapping(value="/{id}", method=RequestMethod.GET)
@ResponseBody
public Prtnr getPartner(@PathVariable("id") String id){
    ....
    ....
return partner;
    }

访问链接localhost：9080 / someApp / testWs / partners / 1＆gt;返回结果，但使用RestTemplate（）。getForObject（）不起作用。

这是Prtnr课程：

public class Prtnr implements Cloneable, java.io.Serializable {

private static final long serialVersionUID = 201207021420600052L;
private Integer prtnrId;
private String creatUserId;
private Date creatTs;
private String updtUserId;
private Date updtTs;
private String prtnrNm;
private Integer cncilNum;
private Character prtnrTypCd;
private Set<PrtnrGeoInfo> prtnrGeoInfos = new HashSet<PrtnrGeoInfo>(0);
private Set<PrtnrDtl> prtnrDtls = new HashSet<PrtnrDtl>(0);
private Set<SuplyDtl> suplyDtls = new HashSet<SuplyDtl>(0);
private Set<TrnsprtDtl> trnsprtDtls = new HashSet<TrnsprtDtl>(0);
private Set<PrtnrFacil> prtnrFacils = new HashSet<PrtnrFacil>(0);
private Set<PrtnrHumanResrc> prtnrHumanResrcs = new HashSet<PrtnrHumanResrc>(0);
.....
.....
Getters and setters for these properties
...
}

我在服务器端看到的错误是： [12/3/12 10：25：57：764 EST] 00000039 ServletWrappe E SRVE0068E：在servlet的一个服务方法中抛出未捕获的异常：

网络服务的卷曲是：线程“main”java.lang.StackOverflowError中的异常 at org.codehaus.jackson.map.deser.BeanDeserializer.deserialize（BeanDeserializer.java:579） at org.codehaus.jackson.map.deser.SettableBeanProperty.deserialize（SettableBeanProperty.java:299） at org.codehaus.jackson.map.deser.SettableBeanProperty $ MethodProperty.deserializeAndSet（SettableBeanProperty.java:414） at org.codehaus.jackson.map.deser.BeanDeserializer.deserializeFromObject（BeanDeserializer.java:697）在org.codehaus.jackson.map.deser.BeanDeserializer.deserialize（BeanDeserializer.java:580）

我缺少什么？

由于

RestTemplate（）。getForObject给出“不是有效的HTTP URL”
