Question

在我的应用程序中，我在触发代码

RestTemplate client=new RestTemplate();
if(ipaddress.length>0)
{
    for (int i = 0; i < ipaddress.length; i++) {
        System.out.println(baseUrl+"/grid/api/proxy?id="+ipaddress[i]);
        ResponseEntity<Object> object= client.getForEntity(baseUrl+"/grid/api/proxy?id="+ipaddress[i], Object.class);
        System.out.println(object);
    }
}

结果对象返回如下所示：

<200 OK,{success=true,
         msg=proxy found !,
         id=http://192.168.3.37:5555,

                  capabilities=[{seleniumProtocol=WebDriver, 
                                 platform=WIN8_1, 
                                 browserName=firefox}, 
                                {seleniumProtocol=WebDriver, 
                                 platform=WIN8_1, 
                                 browserName=chrome}, 
                                {seleniumProtocol=WebDriver, 
                                 platform=WIN8_1, 
                                 browserName=internet explorer}]}},
        {Content-Type=[application/json;charset=UTF-8], 
         Content-Length=[1185], 
         Server=[Jetty(7.x.y-SNAPSHOT)]}>

如果我在响应实体方法中使用JSONObject而不是Object，我会得到{}

如何将Object转换为JSONObject？

注意：我的应用程序不是Web应用程序。

您可以在配置RestTemplate时在application-context.xml中使用以下代码。

<beans:bean id="restTemplate" class="org.springframework.web.client.RestTemplate">
    <constructor-arg ref="httpClientFactory" />
    <property name="messageConverters">
        <list>
            <beans:bean
                class="org.springframework.http.converter.ByteArrayHttpMessageConverter" />
            <beans:bean
                class="org.springframework.http.converter.FormHttpMessageConverter" />
            <beans:bean
                class="org.springframework.http.converter.StringHttpMessageConverter" />
            <beans:bean
                class="org.springframework.http.converter.xml.SourceHttpMessageConverter" />
            <beans:bean
                class="org.springframework.http.converter.xml.MarshallingHttpMessageConverter">
                <constructor-arg>
                    <beans:bean class="org.springframework.oxm.xstream.XStreamMarshaller" />
                </constructor-arg>
            </beans:bean>
            <ref bean="jsonConverter" />
        </list>
    </property>
</beans:bean>
<beans:bean id="jsonConverter"
    class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
    <property name="supportedMediaTypes" value="application/json" />
</beans:bean>
<beans:bean id="annotationMethodHandlerAdapter"
    class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
    <property name="messageConverters">
        <list>
            <ref bean="jsonConverter" />
        </list>
    </property>
</beans:bean>

希望这些东西可以帮助你。如果有任何疑问，请告诉我。

ResponseEntity<Object> object= client.getForEntity(baseUrl+"/grid/api/proxy?id="+ipaddress[i], Object.class);

在这里你可以传递你想要的对象，我建议如果你知道返回的对象结构来创建一个虚拟mixin类，HttpMessage转换器将负责将它转换为你的虚拟类。如果您希望其他JSON提供程序负责反序列化，您可以在ResponseEntity<T>中传递String并手动反序列化。

样本用法：

ResponseEntity<Identifier> postForEntity = postForEntity = getTemplate().postForEntity(builder.toUri(), entity, Identifier.class);
        logger.info("creating creative result : "+postForEntity.getBody());

响应无法转换为JSON
