How to easily use Hymanson for Jersey
提问by daskai0815
I want to use Jersey for implemnting some Java REST services. The default POJO converter JAXB handles JSON objects a bit strange, so I want to use Hymanson for converting POJOs with little or less overhead. How would do I tell the J2ME framework to use another converter?
我想使用 Jersey 来实现一些 Java REST 服务。默认的 POJO 转换器 JAXB 处理 JSON 对象有点奇怪，所以我想使用 Hymanson 以很少或更少的开销来转换 POJO。我如何告诉 J2ME 框架使用另一个转换器？
My web.xml looks like this:
我的 web.xml 看起来像这样：
<!-- Jersey JAVA REST implementation -->
<servlet>
<servlet-name>Jersey</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>org.foobar.rest.services</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Jersey</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>

simply add the Hymanson JARs and modify the web.xml like this:
只需添加 Hymanson JAR 并像这样修改 web.xml：
<!-- Jersey JAVA REST implementation -->
<servlet>
<servlet-name>Jersey</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>org.foobar.rest.services;org.codehaus.Hymanson.jaxrs</param-value> <!-- use Hymanson for JSON -->
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Jersey</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
The required Hymanson JARs ( http://Hymanson.codehaus.org/) are:
所需的 Hymanson JAR ( http://Hymanson.codehaus.org/) 是：
Hymanson-core-asl-1.9.10.jar
Hymanson-core-lgpl-1.9.10.jar
Hymanson-jaxrs-1.9.10.jar
Hymanson-mapper-asl-1.9.10.jar
Hymanson-mapper-lgpl-1.9.10.jar
Hymanson-mrbean-1.9.10.jar
Hymanson-smile-1.9.10.jar
Hymanson-xc-1.9.10.jar

In addition to registering Hymanson 1.x provider, you can alternatively use Hymanson 2.x JSON provider (with Hymanson 2.x databind and core module it depends on): https://github.com/FasterXML/Hymanson-jaxrs-json-providerIt auto-registers itself with service provider interface (1.x did not since it was feared users might be surprised by this, since it's based on existence of a jar in classpath instead of explicit choice).
除了注册 Hymanson 1.x provider，您还可以使用 Hymanson 2.x JSON provider（使用 Hymanson 2.x 数据绑定和它依赖的核心模块）：https: //github.com/FasterXML/Hymanson-jaxrs-json -provider它自动向服务提供者接口注册自己（1.x 没有，因为它担心用户可能会对此感到惊讶，因为它基于类路径中存在的 jar 而不是显式选择）。
EDIT (Sep 2013): As pointed out by @koppor, this module is being deprecated, and replacement ones (JSON, XML, Smile) can be found from https://github.com/FasterXML/Hymanson-jaxrs-providers(thanks!)
编辑（2013 年 9 月）：正如@koppor 所指出的，该模块已被弃用，可以从https://github.com/FasterXML/Hymanson-jaxrs-providers找到替换模块（JSON、XML、Smile）（感谢！）
