java - 为 oxm jaxb2 spring 服务获取 406。编码请求体有效，返回响应体无效

Question

我已将其简化为最简单的示例。我正在使用 Poster 并将标题“Content-Type”添加为“application/xml”。如果没有它，我会收到 415 错误，甚至无法进入 Controller ，有了它，我会进入 Controller 并在绑定(bind)响应之前死亡，因此 system.err.println 会执行，然后它会退出。设置内容类型后，我收到 406 错误(但仍然进入我的 Controller )。

Controller :

package test.test.test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class HomeController {
    @Autowired
    @RequestMapping(value = "/", method = RequestMethod.POST)
    @ResponseBody
    public TestResponse getTest(@RequestBody TestRequest testRequest) {
        System.err.println("testRequest: " + testRequest.getTestData());
        TestResponse t= new TestResponse();
        t.setResponseData("stuff");
        return t;
    }
}

请求:

package test.test.test;
import java.io.Serializable;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
 public class TestRequest implements Serializable {
    private static final long serialVersionUID = -4928814568645262069L;
    private String testData;

    @XmlElement
    public String getTestData() {
         return testData;
     }

     public void setTestData(String testData) {
        this.testData = testData;
    }
}

回复: 包test.test.test;

import java.io.Serializable;


@XmlRootElement
public class TestResponse implements Serializable {

    /**
     * 
     */
    private static final long serialVersionUID = 2007976182805052992L;
    private String responseData="test";
    @XmlElement
    public String getResponseData() {
        return responseData;
    }

    public void setResponseData(String responseData) {
        this.responseData = responseData;
    }
}

Answer 1

您需要向客户端请求添加一个值为 application/xml 的 Accept header 。

406 状态代码意味着服务器认为您的客户端无法接受它正在准备的内容。
