[英]jersey json trying to unmarshall to same object

问题描述

我是球衣和杰克逊的新手。 在我的Web服务中，有两种方法，一种用于GET（学生的json返回），一种用于POST（消耗教师）。 第二个也试图解组将json发布给Student。

这是我的网络服务 

@GET
@Path("/print/{name}")
@Produces(MediaType.APPLICATION_JSON)
public Student produceJSON( @PathParam("name") String name) {

    Student st = new Student(name, "Diaz", 22, 1);

    return st;
}

@POST 
@Path("/send")
@Consumes(MediaType.APPLICATION_JSON)
@Produces("text/html")
public Response consumeJSON(Teacher teacher){


    return Response.ok().build();

}
<?xml version="1.0" encoding="UTF-8"?>

这是我的web.xml 

<servlet>
    <servlet-name>jersey-helloworld-serlvet</servlet-name>
    <servlet-class>
                 com.sun.jersey.spi.container.servlet.ServletContainer
            </servlet-class>
    <init-param>
         <param-name>com.sun.jersey.config.property.packages</param-name>
         <param-value>com.javacodegeeks.enterprise.rest.jersey</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>jersey-helloworld-serlvet</servlet-name>
    <url-pattern>/rest/*</url-pattern>
</servlet-mapping>

pom.xml中的依赖项 

    <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-server</artifactId>
        <version>1.9</version>
    </dependency>

        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-json</artifactId>
        <version>1.9</version>
    </dependency>

发布Ajax Jquery请求 

$.ajax({
      type: "POST",
        headers: {          
            Accept : "text/html; charset=utf-8",         
           "Content-Type": "application/json; charset=utf-8"   
        },
      url: "http://localhost:8086/JAXRS-HelloWorld/rest/jsonServices/send",
      data: JSON.stringify({"name": "John", "surname": "doe" }),
      success: alert("successs"),
      dataType: "application/json",
    });

并得到错误

学生 （id，名字，姓氏，年龄）， 老师 （姓名，姓氏）

从错误中您可以看到，球衣试图解编给Student，即使没有使用过Student也无法在Student中找到字段名称。

不是：在POST服务中，我使用了Student，并将其更改为Teacher。 这个问题可以和任何兑现有关吗？

这是某种版本问题。 现在，我将其升级到jersey 2.x和jackson 2.x，他们似乎完美地合作了。
