如何使用JAXB使用Jersey 1.17.1生成JSON输出

Question

本网站已经有了这个问题的正确答案.问题是问题是针对泽西岛1.6,泽西岛1.17.1的正确答案是埋在底部.我想我会为这个答案创建一个正确的问题,这样就可以更容易地为那些在这方面苦苦挣扎的人找到帮助(就像我一样).

Answer 1

首先,您需要将其添加到您的web.xml:

<servlet>
    <servlet-name>JerseyServlet</servlet-name>
    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
        <param-value>true</param-value>
    </init-param>

然后,选择要通过网络序列化的任何类,并将此注释添加到它们的顶部:

import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement
public class ...

然后将适当的jar添加到类路径中.添加泽西罐子是不够的,你还需要添加杰克逊.我下载了包含12个不同罐子的拉链.一旦我将所有12个罐子添加到我的类路径中,我终于摆脱了错误,并且很好地返回了JSON.

我希望这有助于某人.

下载带有12个Jars的Zip: 这是包含12个jar文件的zip文件的链接:jersey-archive-1.17.zip

对于Maven用户: 将以下内容添加到您的pom.xml中以分别获取12个罐子:
