HTTP 415不支持的媒体类型

Question

我已经创建了一个示例web服务来进行post调用。

我使用的是Jersey JAX-RS和Maven。

<servlet>
    <servlet-name>provider-serlvet</servlet-name>
    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
        <init-param>
            <param-name>javax.ws.rs.Application</param-name>
            <param-value>org.is.ws.provider.rest.ProviderAggregateApplication</param-value>
        </init-param>
        <init-param>
            <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
            <param-value>true</param-value>
         </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>provider-serlvet</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

@POST
@Path(RESOURCE_PATH)
@Produces("text/plain")
public String getPCP(){
    return "Hello";
}

    "patientID": "1234567890",
    "patientIDType": "XYZ"
  }

我删除了pom.xml中的所有依赖项代码，并添加了以下代码，这些代码包括jersey-core、jersey-bundle、jersey-json

 <dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-bundle</artifactId>
    <version>1.19</version>
</dependency>
<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-json</artifactId>
    <version>1.19</version>
</dependency>
<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-core</artifactId>
    <version>1.19</version>
</dependency>
