Java Spring-Rest控制器字符串响应_Java_Spring_Rest_Get

Java Spring-Rest控制器字符串响应

java spring rest

Java Spring-Rest控制器字符串响应,java,spring,rest,get,Java,Spring,Rest,Get,我有一个用于Rest服务的Spring控制器： @Controller @RequestMapping(value = "/sample") public class SampleController { @RequestMapping(value = "/getText", method = RequestMethod.GET, produces = "text/plain") @ResponseBody public String testMethod(@Reques

我有一个用于Rest服务的Spring控制器：

@Controller
@RequestMapping(value = "/sample")
public class SampleController
{
    @RequestMapping(value = "/getText", method = RequestMethod.GET, produces = "text/plain")
    @ResponseBody
    public String testMethod(@RequestParam("locale") final  String locale) {
        return  "Hello Worlds TEXT";
    }
}

当我在

https://localhost:9002/sample/getText?locale=en

，我将收到错误“找不到可接受的表示”。但我需要一个纯文本。你能解释一下我怎么能得到一个简单的文本吗

这个问题没有解决

我有以下几点：

这可能是因为@ResponseBody注释：

@ResponseBody注释告诉控制器返回的对象被自动序列化为JSON并传递回HttpResponse对象。

嘿，你的代码运行得很好。我也试过。请参阅下面的代码。请确保您发送的get请求正确无误

    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.bind.annotation.RequestParam;
    import org.springframework.web.bind.annotation.ResponseBody;

    @Controller
    @RequestMapping(value = "/sample")
    public class SampleController {

        @RequestMapping(value = "/getText", method = RequestMethod.GET, produces = "text/plain")
        @ResponseBody
        public String testMethod(@RequestParam("locale") final String locale) {
            return "Hello Worlds TEXT";
        }

我没问题，只要给客户提供正确的控制器和服务就行了。您应该为ClientResponse设置“application/plain”，例如：

        Client client = Client.create();    
        WebResource resource = client.resource("http://localhost:8181/SpringMVC/sample/getText.do?locale=en");    
        ClientResponse response = resource.accept("application/plain").get(ClientResponse.class);

您的Rest客户端控制器将是：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class CustomerController {
    @Autowired
    RESTfulClient rESTfulClient;

    @RequestMapping(value = "showResponse")
    public String getResponse() {
        String respose = rESTfulClient.getResponse();
        System.out.println("output: "+respose);
        return "showCustomer";
    }
}

Rest客户端服务将类似于：

 import org.springframework.stereotype.Service;

    import com.sun.jersey.api.client.Client;
    import com.sun.jersey.api.client.ClientResponse;
    import com.sun.jersey.api.client.WebResource;

    @Service
    public class RESTfulClient {

       public String getResponse(){
           String output="hello";
             try {
                    Client client = Client.create();    
                    WebResource resource = client.resource("http://localhost:9002/SpringMVC/sample/getText.do?locale=en");    
                    ClientResponse response = resource.accept("application/plain").get(ClientResponse.class);

                    if(response.getStatus() == 200){

                        output = response.getEntity(String.class);
                        System.out.println(output);    

                    }else System.out.println("Somthing went wrong..!");        

                  } catch (Exception e) {    
                          e.printStackTrace();    
                  }
            return output;

            }   
    }

这个问题已经解决了。 Spring的AbstractHttpMessageConverter功能是为我的项目定制的。当我问这个问题时，我并不知道。文本/纯文本没有任何转换器。json只有一个Jaxb2HttpMessageConverter转换器。我添加了转换器：

 <bean id="stringHttpMessageConverter" class="org.springframework.http.converter.StringHttpMessageConverter">
        <property name="supportedMediaTypes">
            <list>
                <util:constant id="text_plain" static-field="org.springframework.http.MediaType.TEXT_PLAIN"/>
            </list>
        </property>
    </bean>

很好。

希望这能帮助别人

尝试使用

MediaType

而不是字符串文字：

products=org.springframework.http.MediaType.TEXT\u PLAIN

从方法中删除

@ResponseBody

的可能重复项。Polywhill，如果我放置products=org.springframework.http.MediaType.TEXT\u PLAIN，则会发生编译时错误尝试使用
