Spring integration HTTP客户端与spring集成

我需要编写一个简单的HTTP客户端，使用Spring集成生成简单的GET请求和JSON响应。 调用失败，异常中没有消息：org.springframework.web.client.HttpServerErrorException:500内部服务器错误。 我试着调试Spring代码，并成功地完成了它，直到我有了源代码，即till 在方法AbstractMessageHandler.HandleMessageMessageMessage中 已调用抽象handleMessageInternalMessage消息，该消息引发 例外情况是说，请求 URL={q}&authKey={authKey}&rows={rows}&page={page}&filter={filter} 失败。URL看起来和我引用的一模一样，即表达式没有被执行

消息中的有效负载始终保持其应有的状态-如果输入具有正确的字段值，则为实例

谁能告诉我该怎么办

以下是spring-integration-zt-context.xml：

有效载荷：

private String rows="20";

private String filter = "";


public ZtInputVO() {

public String getQ() {
    return q;
}
public void setQ(String q) {
    this.q = q;
}
public String getAuthKey() {
    return authKey;
}
public void setAuthKey(String authKey) {
    this.authKey = authKey;

    return rows;

}

异常中的URI是原始的未扩展URI；展开将执行到不同的变量中。我们应该/将更改它以记录扩展的URI。但底线是您的服务器不喜欢扩展的URI，并返回了500个内部服务器错误

您可以使用eclipse内置的网络/tcp监视器，也可以使用wireshark检查发送到服务器的实际URL。如果启用，还可以查看服务器日志

或者，在调试器中，转到当前源代码版本4.0.4中的第415行并检查realUri

编辑：异常现在包括中当前可用的扩展URI。

非常感谢。我确实被包含未处理URI的异常消息误导了。你把它修好了真是太好了。
