AngularJS 客户端，JAX-RS Jersey Rest 服务 - 应用程序/json 客户端请求抛出“解析媒体类型错误”

【问题标题】：AngularJS Client, JAX-RS Jersey Rest Service - application/json client request throwing 'Error parsing media type'AngularJS 客户端，JAX-RS Jersey Rest 服务 - 应用程序/json 客户端请求抛出“解析媒体类型错误”
【发布时间】：2013-08-02 02:43:31
【问题描述】：

我正在使用以下 AngularJS 客户端代码向球衣休息服务执行带有 JSON 格式有效负载的 HTTP 发布请求

patientMgmtModule.controller('NewPatientCtrl',
function NewPatientCtrl($scope, $http)
{
    $scope.addPatient = function (){

    var patientJSON = angular.toJson($scope.Patient);
    console.log("Patient (JSON) is ============> " + patientJSON);

    $http({
      method: 'POST',
      data: $scope.Patient,
      url:'/ManagePatient/AddPatient',
      headers: {'Content-Type':'application/x-www-form-urlencoded;application/json;'}
    });
};

} );

我对 Jersey 有以下 maven 依赖项：

 <dependency>
    <groupId>org.glassfish.jersey.archetypes</groupId>
    <artifactId>jersey-quickstart-webapp</artifactId>
    <version>2.0</version>
  </dependency>
  <dependency>
    <groupId>org.glassfish.jersey.containers</groupId>
    <artifactId>jersey-container-servlet-core</artifactId>
    <version>2.0</version>
  </dependency>

在服务器端，我有

import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import com.hms.app.ui.beans.Patient;

@Path("/ManagePatient")
public class PatientController {

  @POST
  @Path("/AddPatient")
  @Consumes({MediaType.APPLICATION_JSON})
  public String addPatient(Patient patient) {
    System.out.println("Sarat's servlet called" );
    //patient.toConsole();
    System.out.println("Done Calling Patient To Console");
    return "Done Calling Patient To Console";
  } 
}

当我在客户端提交表单时，我在 chrome 控制台中看到以下错误 -

POST http://localhost:8080/HMS_Web/services/ManagePatient/AddPatient 500 (Internal Server Error) angular.min.js:99

在服务器端，我看到了（高级细节 1）：

SEVERE: Servlet.service() for servlet [Jersey REST Service] in context with path [/HMS_Web] threw exception
org.glassfish.jersey.message.internal.HeaderValueException: Unable to parse "Content-Type" header value: "application/x-www-form-urlencoded;application/json;"

最后的堆栈跟踪是这样的：

Caused by: java.text.ParseException: Expected separator '=' instead of '/'

实施 LoggingFilter 后 - 我看到服务器正在响应 HTTP 415。

    【解决方案1】：

    您的 Content-Type 标头无效（请参阅规范 14.17 Content-Type）。根据您的 JAX-RS 资源，您应该使用 application/json 作为 Content-Type（没有 application/x-www-form-urlencoded）：

    $http({
  method: 'POST',
  data: $scope.Patient,
  url:'/ManagePatient/AddPatient',
  headers: {'Content-Type':'application/json'}
});

    编辑 1：

    如果您想查看到达您服务器的请求，您可以注册LoggingFilter，它会向您显示一些有用的信息。您可以在以下位置开启它：

    web.xml（将其添加到 JAX-RS servlet 定义中）：

    <init-param>
    <param-name>jersey.config.server.provider.classnames</param-name>
    <param-value>org.glassfish.jersey.filter.LoggingFilter</param-value>
</init-param>

    Application分机：

    public class MyApplication extends Application {

    @Override
    public Set<Class<?>> getClasses() {
        return new HashSet<Class<?>>() {{
            // Add your resources.
            add(HelloWorldResource.class);

            // Add LoggingFilter.
            add(LoggingFilter.class);
        }};
    }
}

    ResourceConfig 实例（演示也在这里输出实体）：

    public class MyApplication extends ResourceConfig {

    public MyApplication() {
        // Resources - add your package name here to enable package scanning.
        packages(...);

        // Enable LoggingFilter & output entity.     
        registerInstances(new LoggingFilter(Logger.getLogger(MyApplication.class.getName()), true));
    }
}

    编辑 2：

    Jersey 2.x 不支持开箱即用的 application/json 媒体类型 - 您需要将其中一个 JSON 模块添加到您的类路径（请参阅用户指南中的 JSON 部分），例如：

    <dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-moxy</artifactId>
    <version>2.0</version>
</dependency>

    【讨论】：

    • 但没有 (application/x-www-form-urlencoded) - 来自 Angular js 客户端的请求不会作为 json 请求发布到服务器端......它被发布为文本/html。
    • 你为什么会这样认为？您可以尝试将 LoggingFilter 注册到您的 Jersey 2.x 应用程序中以查看从 JS 客户端发送的标头吗？
    • 我正在尝试将 LoggingFilter 添加为 specified here...但这似乎不起作用！试图弄清楚如何为泽西岛实现 LoggingFilter .. 感谢您的指导！
    • 查看答案，了解如何在 Jersey 2.x 中注册 LoggingFilter。
    • 感谢 v.v.v.v.much 的帮助...我能够配置 LoggingFilter。我看到请求被发布到服务器并且服务器正在响应 http 代码 415。（使用此信息更新了问题）...试图弄清楚如何解决它。
