Apache CXF Spring 休息服务 POST 请求 returns "msg" : "Stream closed"

Question

我使用 Apache Cxf，Spring Jax-rs 服务，我有以下服务定义和提供的实现，

定义

    @POST
    @Path("/generateAddress")
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces({MediaType.APPLICATION_JSON})
    WalletInfo generateAddress(final String walletName, String currencyName);

实施

public synchronized WalletInfo generateAddress(final String walletName, String currencyName) {

        WalletInfo walletInfo = IWalletInfoDao.getWalletInfoWithWalletNameAndCurrency(walletName, currencyName);
        return walletInfo;
}

当我用 cURL 发出 POST 请求时 curl -H "Content-Type: application/json" -X POST -d '{"walletName":"Icecream5500","currencyName":"Bitcoin"}' http://localhost:8080/api/rest/wallet/generateAddress

我收到 JSON 回复，

{
  "msg" : "Stream closed",
  "date" : "2017-08-28T09:22:027Z"
}

我很确定 generateAddress 方法工作正常。什么是
这里的问题，特别是当您在执行 POST 请求时在 Spring Apache Cxf 项目中收到消息 Stream closed 时？显然，如果需要，我可以提供更多信息。服务器日志正常，没有发现异常。

POST 主体与方法的参数不匹配，这首先造成了问题。我已经在以下选项中解决了这个问题。

我新建了一个class

public class CreateWalletWithNameAndCurrency {

    String walletName;

    String currencyName;

    public CreateWalletWithNameAndCurrency(String walletName, String currencyName) {
        this.walletName = walletName;
        this.currencyName = currencyName;
    }

    public CreateWalletWithNameAndCurrency() {
    }

    public String getWalletName() {
        return walletName;
    }

    public String getCurrencyName() {
        return currencyName;
    }

    public void setCurrencyName(String currencyName) {
        this.currencyName = currencyName;
    }

    public void setWalletName(String walletName) {
        this.walletName = walletName;
    }
}

我像这样更改了 POST 请求的定义，

@POST
@Path("generateAddress")
@Consumes(MediaType.APPLICATION_JSON)
@Produces({MediaType.APPLICATION_JSON})
WalletInfo generateAddress(CreateWalletWithNameAndCurrency createWalletWithNameAndCurrency);

下面提供了实现，

public synchronized WalletInfo generateAddress(CreateWalletWithNameAndCurrency createWalletWithNameAndCurrency) {

        String walletName = createWalletWithNameAndCurrency.getWalletName();

        String currencyName = createWalletWithNameAndCurrency.getCurrencyName();

        WalletInfo walletInfo = iWalletInfoDao.getWalletInfoWithWalletNameAndCurrency(walletName, currencyName);


    // some more code 
}

终于，我可以像这样完成 POST 请求了，

curl -H "Content-Type: application/json" -X POST -d '{"walletName":"Copenhangen","currencyName":"Bitcoin"}' http://localhost:8080/rest/wallet/generateAddress
