Question

I m试图利用阿帕奇-CXF在日本宇宙航空研究开发机构-RS的前线开发一个REE服务。对于开端人,我有一个称为<条码>测试的方法,该方法接收<条码>、条码信息和<条码>。我希望客户能够把这些参数输入到一个局域网信息机构。我似乎无法做到这一点。

在我之前,这里有一些细节:

I m using CXF without Spring
It s not a web app, so I don t have the WEB-INF folder with the web.xml
I test the service using SoapUI and Postman (Google Chrome application)

我收到以下代码<代码>。 WARNING: javax.ws.rs.BadRequestException: HTTP 400 Bad Request:

DemoService.java

@WebService(targetNamespace = "http://demoservice.com")
@Path("/demoService")
public interface DemoService {
    @POST
    @Path("/test")
    @Produces(MediaType.APPLICATION_JSON)
    @Consumes(MediaType.APPLICATION_JSON)
    public String test (String message, int value);
}

DemoserviceImpl.java

public class DemoServiceImpl implements DemoService {
    @Override
    public String test(String message, int value) {
        return "test message: " + message + " value =  : " + value;
    }
}

DemoServer.java

public class DemoServer{
    public static void main(String[] args) {

        JAXRSServerFactoryBean serverFactory = new JAXRSServerFactoryBean();
        DemoService demoService = new DemoServiceImpl();
        serverFactory.setServiceBean(demoService);
        serverFactory.setAddress("http://localhost:9090");
        serverFactory.create();
    }
}

Testing with {"message":"hello there!", "value":"50"} to the URL http://localhost:9090/demoService/test gave a HTTP 400 Bad Reuest.

Then I saw this question on S.O.: How to access parameters in a RESTful POST method and tried this:

添加了DemoServer的以下nes类。 java:

    @XmlRootElement
    public static class TestRequest {
        private String message;
        private int value;

        public String getMessage() { return message; }
        public void setMessage(String message) { this.message = message; }
        public int getValue() { return value; }
        public void setValue(int value) { this.value = value; }
    }

我还修改了“民主服务”接口和执行,将这一类别作为<条码>测试<>/代码>方法的参数,尽管这最终仍不是我想要做的事。 (在此说明执行情况,问题已久)

@Override
public String test(TestRequest testRequest) {
    String message = testRequest.getMessage();
    int value = testRequest.getValue();
    return "test message: " + message + " value =  : " + value;
}

And to fix this error that I got: SEVERE: No message body reader has been found for class DemoService$TestRequest, ContentType: application/json (in Postman I see error 415 - unsupported media type) I added the following dependencies (jettison and another thing) to the POM.xml:

<dependency>
    <groupId>org.codehaus.jettison</groupId>
    <artifactId>jettison</artifactId>
    <version>1.3.5</version>
</dependency>
<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-rt-rs-extension-providers</artifactId>
    <version>2.6.0</version>
</dependency>

我在一份吉斯蒂尔·波萨雷斯的请求中,用以下信对这项服务进行了测试:

{"testRequest":{"message":"hello there!", "value":"50"}}

这一工作。尽管这一解决办法是,我使用测试研究组来概括参数的工作,但这不是解决办法一。我想通过JSON电文中的两个参数,而不必引入这一试卷(明示)。

问题:

Would this be easier to implement using Jersey?
I don t have a web.xml nor a WEB-INF folder, so I can t configure CXF in a cxf.xml file can I? A lot of tutorials online seem ot use a lot of XML configuration, but I don t want to deploy a framework like TomEE or Spring or Glassfish just to do that.
Searching online for solutions, I came across Spring Boot. Would you recommend using that, perhaps? Would that make developing web services like this easier?
Also, how do I get it to return the value in JSON format (or is it not supposed to do that for Strings?)

Answer 1

我的朋友向我指出了这一分点交换问题:JAX-RS 多个目标

and also the following documentation: http://cxf.apache.org/docs/jax-rs-and-jax-ws.html

which states:

public class CustomerService { public void doIt(String a, String b) {...}; }

By default JAX-RS may not be able to handle such methods as it requires that only a single parameter can be available in a signature that is not annotated by one of the JAX-RS annotations like @PathParam. So if a String a parameter can be mapped to a @Path template variable or one of the query segments then this signature won t need to be changed :

@Path("/customers/{a}") public class CustomerService { public void doIt(@PathParam("a") String a, String b) {...}; }

因此,为了回答我的问题,诺先生无法回答。
