Java 如何将JSON对象从POSTMAN发送到Restful Web服务

我正在尝试将json从POSTMAN发送到RESTfulWebService。我遵循本教程通过邮递员发送json

我的URL:

@POST
    @Path("/insert")
    @Consumes(MediaType.APPLICATION_JSON)
    public String insertData(JSONObject jsonlist) throws UnknownHostException;

@Override
    public String insertData(JSONObject jsonlist) throws UnknownHostException {
        System.out.println(jsonlist);
        insertDataDao.insertData(jsonlist);
        return "SUCCESS";
    }

public  String insertData(JSONObject jsonlist) throws UnknownHostException{
        System.out.println(jsonlist);
        MongoConnection mongoconnection = new MongoConnection();
        MongoClient mongoclient = mongoconnection.getMongoClient();

        MongoDatabase db = mongoclient.getDatabase("mydb");
        MongoCollection<Document> col = db.getCollection("col");

        String jsonString = jsonlist.toString();
        System.out.println(jsonString);

        Document doc = Document.parse(jsonString);
         col.insertOne(doc);
        System.out.println("Inserted Successfully !!!");
        return "SUCCESS";

    }

我的服务方式：

@POST
    @Path("/insert")
    @Consumes(MediaType.APPLICATION_JSON)
    public String insertData(JSONObject jsonlist) throws UnknownHostException;

@Override
    public String insertData(JSONObject jsonlist) throws UnknownHostException {
        System.out.println(jsonlist);
        insertDataDao.insertData(jsonlist);
        return "SUCCESS";
    }

public  String insertData(JSONObject jsonlist) throws UnknownHostException{
        System.out.println(jsonlist);
        MongoConnection mongoconnection = new MongoConnection();
        MongoClient mongoclient = mongoconnection.getMongoClient();

        MongoDatabase db = mongoclient.getDatabase("mydb");
        MongoCollection<Document> col = db.getCollection("col");

        String jsonString = jsonlist.toString();
        System.out.println(jsonString);

        Document doc = Document.parse(jsonString);
         col.insertOne(doc);
        System.out.println("Inserted Successfully !!!");
        return "SUCCESS";

    }

我的建议：

@POST
    @Path("/insert")
    @Consumes(MediaType.APPLICATION_JSON)
    public String insertData(JSONObject jsonlist) throws UnknownHostException;

@Override
    public String insertData(JSONObject jsonlist) throws UnknownHostException {
        System.out.println(jsonlist);
        insertDataDao.insertData(jsonlist);
        return "SUCCESS";
    }

public  String insertData(JSONObject jsonlist) throws UnknownHostException{
        System.out.println(jsonlist);
        MongoConnection mongoconnection = new MongoConnection();
        MongoClient mongoclient = mongoconnection.getMongoClient();

        MongoDatabase db = mongoclient.getDatabase("mydb");
        MongoCollection<Document> col = db.getCollection("col");

        String jsonString = jsonlist.toString();
        System.out.println(jsonString);

        Document doc = Document.parse(jsonString);
         col.insertOne(doc);
        System.out.println("Inserted Successfully !!!");
        return "SUCCESS";

    }

我的刀：

@POST
    @Path("/insert")
    @Consumes(MediaType.APPLICATION_JSON)
    public String insertData(JSONObject jsonlist) throws UnknownHostException;

@Override
    public String insertData(JSONObject jsonlist) throws UnknownHostException {
        System.out.println(jsonlist);
        insertDataDao.insertData(jsonlist);
        return "SUCCESS";
    }

public  String insertData(JSONObject jsonlist) throws UnknownHostException{
        System.out.println(jsonlist);
        MongoConnection mongoconnection = new MongoConnection();
        MongoClient mongoclient = mongoconnection.getMongoClient();

        MongoDatabase db = mongoclient.getDatabase("mydb");
        MongoCollection<Document> col = db.getCollection("col");

        String jsonString = jsonlist.toString();
        System.out.println(jsonString);

        Document doc = Document.parse(jsonString);
         col.insertOne(doc);
        System.out.println("Inserted Successfully !!!");
        return "SUCCESS";

    }

公共字符串insertData（JSONObject jsonlist）抛出UnknownHostException{
System.out.println（jsonlist）；
MongoConnection MongoConnection=新的MongoConnection（）；
MongoClient MongoClient=mongoconnection.getMongoClient（）；
MongoDatabase db=mongoclient.getDatabase（“mydb”）；
MongoCollection col=db.getCollection（“col”）；
字符串jsonString=jsonlist.toString（）；
System.out.println（jsonString）；
Document doc=Document.parse（jsonString）；
insertOne上校（博士）；
System.out.println（“插入成功！！！”；
返回“成功”；
}

但我面临以下例外：

JBWEB000236:Servlet CXFServlet的Servlet.service（）引发异常：java.lang.NoSuchMethodError:javax.ws.rs.InternalServerErrorException.validate（Ljavax/ws/rs/core/Response；Ljavax/ws/rs/core/Response$Status；）Ljavax/ws/rs/core/Response

我无法解决这个问题。有人能帮我解决这个问题吗…

步骤1：打开邮递员键入api url并选择post类型

步骤2：转到标题按钮类型（“内容类型”）第一个输入框，在第二个输入框中键入“application/json”，它会给出自动完成建议

步骤3：转到正文按钮并选择原始单选按钮，然后在同一原始右侧的下拉列表中选择JSON（应用程序/JSON）

步骤4：键入类似json的学生对象

{
  "name": "dummy",
  "marks": "26"
}

POSTMAN V5.2.0测试 网址：

JSON数据：

{"name":"John","firstName":"Smith","lastName":"MT","email":"johnsmt@yahoo.com"}

步骤：

外接程序标题

通过单击

BODY

->

raw

->

JSON（应用程序/JSON）

单击send并查看JSON/XML中的响应文本

注意：

@POST
    @Path("/insert")
    @Consumes(MediaType.APPLICATION_JSON)
    public String insertData(JSONObject jsonlist) throws UnknownHostException;

@Override
    public String insertData(JSONObject jsonlist) throws UnknownHostException {
        System.out.println(jsonlist);
        insertDataDao.insertData(jsonlist);
        return "SUCCESS";
    }

public  String insertData(JSONObject jsonlist) throws UnknownHostException{
        System.out.println(jsonlist);
        MongoConnection mongoconnection = new MongoConnection();
        MongoClient mongoclient = mongoconnection.getMongoClient();

        MongoDatabase db = mongoclient.getDatabase("mydb");
        MongoCollection<Document> col = db.getCollection("col");

        String jsonString = jsonlist.toString();
        System.out.println(jsonString);

        Document doc = Document.parse(jsonString);
         col.insertOne(doc);
        System.out.println("Inserted Successfully !!!");
        return "SUCCESS";

    }

用户在URL中引用REST Spring控制器

@RestController
@请求映射（“/user”）

注册在URL中引用

@RequestMapping（value=“/register”，method=RequestMethod.POST，products=“application/json”，consumes=“application/json”）

我遇到了同样的问题，通过先导入

jersey.json

依赖项，然后将其添加到

web.xml

<init-param>
        <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
        <param-value>true</param-value>
    </init-param>

com.sun.jersey.api.json.POJOMappingFeature
真的

您在服务中使用的是哪个版本的cxf我使用的是2.7.13版本的cxf邮差呼叫没有任何错误。你能在你提出请求的地方添加一些方法的代码吗。方法的返回类型应该是Response@与应用程序运行时相比，dev777jax-rs实现的编译时间不同。检查JBOSS服务器使用的CXF版本。是。我也做了同样的事。但我无法将此json数据发送到webservice。在《邮递员》中单击“发送”按钮，我就面临上面提到的问题
