从Moxy到Jackson的Weblogic 12.2.1.3 [英] Weblogic 12.2.1.3 from Moxy to Jackson

问题描述

我想将JSON解析器从Moxy更改为Jackson，并且我遵循了共享库方法，但没有任何结果，仍使用Moxy.

I would like to change the JSON parser from Moxy to Jackson, and I have followed the shared library approach, but without any result, Moxy is still used.

注意:共享库不是必需的！！

Note: the shared library is not necessary!!!

我创建了一个具有以下依赖项和描述符的maven项目.

I have created a maven project with the following dependencies and descriptors.

 <properties>
    <jackson.annotations.release>2.8.6</jackson.annotations.release>
    <jersey.version>2.22.4</jersey.version>

MANIFEST.MF

Web应用程序

我添加web.xml和weblogic.xml.

Web Application

I add the web.xml and the weblogic.xml.

<servlet>
    <servlet-name>com.dummy.MyApplication</servlet-name>
        <init-param>
            <param-name>jersey.config.server.provider.classnames</param-name>
            <param-value>com.fasterxml.jackson.jaxrs.json.JacksonJaxbJsonProvider</param-value>
        </init-param>
</servlet>

<servlet-mapping>
    <servlet-name>com.dummy.MyApplication</servlet-name>
    <url-pattern>/api/*</url-pattern>
</servlet-mapping>

weblogic.xml

<?xml version="1.0" encoding="UTF-8"?>
<weblogic-web-app xmlns="http://xmlns.oracle.com/weblogic/weblogic-web-app">
    <library-ref>
        <library-name>jstl</library-name>
        <specification-version>1.2</specification-version>
        <implementation-version>1.2</implementation-version>
        <exact-match>false</exact-match>
    </library-ref>
    <library-ref>
        <library-name>jackson-weblogic</library-name>
        <specification-version>1.0</specification-version>
        <exact-match>false</exact-match>
    </library-ref>
</weblogic-web-app>

然后，我在weblogic.xml共享库中进行引用，但仍使用Moxy.我做错了什么吗?

Then I reference in the weblogic.xml the shared library, but Moxy is still used. Have I done something wrong?

更新:我已经添加了Web应用程序的web.xml和weblogic.xml.

Update: I have added the web.xml and the weblogic.xml of the web application.

我检查了文件夹oracle_common\modules，并且找到了所需的所有Jackson依赖项.因此，我更喜欢将Jersey配置为禁用MOXy，如下所示:

I have checked the folder oracle_common\modules and I have found all the Jackson dependencies needed. So I have preferred to configure Jersey to disable the use of MOXy as follows:

import javax.ws.rs.core.Application;
public class MyApplication extends Application
{
    @Override
    public Map<String, Object> getProperties()
    {
        Map<String, Object> proprties = new HashMap<>();
        proprties.put("jersey.config.server.disableMoxyJson", true);

        return proprties;
    }
}

关注:

• 方法getProperties()随javax.ws.rs 2.0一起提供；
• Jackson不需要特定的共享库，只需jstl 和jax-rs 2.0;
• web.xml内不需要任何信息；
正如@abbas所报告的，
• 默认情况下，Weblogic 12.2.1.3.0附带有JAX-RS 2.0，在我的情况下，我对javax.ws.rs:jsr311-api具有传递依赖，因此未调用方法getProperties().

• that the method getProperties() comes with javax.ws.rs 2.0;
• no specific shared library is necessary for Jackson, but just for jstl and jax-rs 2.0;
• no info inside web.xml is required;
• as reported by @abbas JAX-RS 2.0 comes by default with Weblogic 12.2.1.3.0 in my case I has a transitive dependency on javax.ws.rs:jsr311-api so the method getProperties() was not invoked.

推荐答案

Mention JAX-RS 2.0作为pom.xml中的依赖项

Mention JAX-RS 2.0 as a dependency in your pom.xml

<dependency>
    <groupId>javax.ws.rs</groupId>
    <artifactId>javax.ws.rs-api</artifactId>
    <version>2.0.1</version>
    <scope>provided</scope>
</dependency>

在WebLogic 12.2.1中，您无需将其部署为共享库.

In WebLogic 12.2.1 you do not need to deploy it as a shared library.
