Java 在http请求连接器中传递动态查询参数和路径参数

java spring mule

Java 在http请求连接器中传递动态查询参数和路径参数,java,spring,mule,mule-studio,mule-component,Java,Spring,Mule,Mule Studio,Mule Component,我希望将查询参数和路径参数列表传递给http请求mule连接器。此连接器的输入是一个pojo列表，其中包含查询和路径参数的值 http请求连接器如下所示： <http:request config-ref="HTTP_Request_Configuration" path="/rates/api/v1/rates/{in}.csv" method="GET" doc:name="End_HTTP request"> <http:request-builder> &

我希望将查询参数和路径参数列表传递给http请求mule连接器。此连接器的输入是一个pojo列表，其中包含查询和路径参数的值

http请求连接器如下所示：

<http:request config-ref="HTTP_Request_Configuration" path="/rates/api/v1/rates/{in}.csv" method="GET" doc:name="End_HTTP request">
<http:request-builder>
    <http:query-param paramName="api_key"
        value="abcde" />
    <http:query-param paramName="quote" value={target_currency} />
    <http:query-param paramName="date" value={date} />
    <http:query-param paramName="fields" value="averages" />
    <http:uri-param paramName="in" value={source_currency} />
</http:request-builder>

如果http请求连接器的输入是数据类的对象，那么如何设置查询和路径参数

有人能帮我举个例子吗

多谢各位

我认为您需要在流中添加一个数据对象（流变量）。然后可以在请求生成器中使用变量，如

{flowVars.variable.someproperty}

首先必须将对象数据（即有效负载）中的值分配给所需的变量（targetCurrency、date、sourceCurrency），然后必须将变量的值分配给查询参数和路径参数。这里有一个例子：

这是我正在使用的类：

package com.testing.domain;

import java.util.List;

public class GeneralRequest {
    private String processTypeJob;
    private String waitTime;
    private List<String> processIds;
    private String processTypeGroup;
    private List<JobConfiguration> jobConfigurations;

    public String getProcessTypeJob() {
        return processTypeJob;
    }
    public void setProcessTypeJob(String processTypeJob) {
        this.processTypeJob = processTypeJob;
    }
    public List<String> getProcessIds() {
        return processIds;
    }
    public void setProcessIds(List<String> processIds) {
        this.processIds = processIds;
    }
    public String getProcessTypeGroup() {
        return processTypeGroup;
    }
    public void setProcessTypeGroup(String processTypeGroup) {
        this.processTypeGroup = processTypeGroup;
    }
    public List<JobConfiguration> getJobConfigurations() {
        return jobConfigurations;
    }
    public void setJobConfigurations(List<JobConfiguration> jobConfigurations) {
        this.jobConfigurations = jobConfigurations;
    }
    public String getWaitTime() {
        return waitTime;
    }
    public void setWaitTime(String waitTime) {
        this.waitTime = waitTime;
    }



}

有关更多信息，请参见下一个链接：

在“http:request”之前，流的有效负载是多少？是数据列表还是仅是数据类的实例？。因为在问题的第一部分你谈论一个列表，在最后一部分你谈论一个对象。

package com.testing.domain;

import java.util.List;

public class GeneralRequest {
    private String processTypeJob;
    private String waitTime;
    private List<String> processIds;
    private String processTypeGroup;
    private List<JobConfiguration> jobConfigurations;

    public String getProcessTypeJob() {
        return processTypeJob;
    }
    public void setProcessTypeJob(String processTypeJob) {
        this.processTypeJob = processTypeJob;
    }
    public List<String> getProcessIds() {
        return processIds;
