如何轻松地将杰克逊用于泽西岛 [英] How to easily use Jackson for Jersey

问题描述

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Jackson来转换POJO，只需要很少或更少的开销。如何告诉J2ME框架使用另一个转换器？

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 Jackson for converting POJOs with little or less overhead. How would do I tell the J2ME framework to use another converter?

我的web.xml如下所示：

My web.xml looks like this:

<!-- 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>

推荐答案

只需添加jackson JAR并修改web.xml像这样：

simply add the jackson JARs and modify the web.xml like this:

<!-- 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.jackson.jaxrs</param-value>    <!--  use jackson 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>

所需的杰克逊JAR（ http://jackson.codehaus.org/ ）是：

The required Jackson JARs ( http://jackson.codehaus.org/ ) are:

jackson-core-asl-1.9.10.jar
jackson-core-lgpl-1.9.10.jar
jackson-jaxrs-1.9.10.jar
jackson-mapper-asl-1.9.10.jar
jackson-mapper-lgpl-1.9.10.jar
jackson-mrbean-1.9.10.jar
jackson-smile-1.9.10.jar
jackson-xc-1.9.10.jar
