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效果，还是用了Moxy。

Note:共享库不是必需的！

The shared library

我创建了一个具有以下依赖项和描述符的 Maven 项目。

pom.xml

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

        <version>${jackson.annotations.release}</version>
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.jaxrs</groupId>
        <artifactId>jackson-jaxrs-json-provider</artifactId>
        <version>${jackson.annotations.release}</version>
    </dependency>

    <!-- Jersey dependencies -->
    <dependency>

MANIFEST.MF

Manifest-Version: 1.0

Implementation-Version: 1.0

Specification-Version: 1.0

Web Application

我添加web.xml和weblogic.xml.

web.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>

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

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

Solution

我已经检查了文件夹oracle_common\modules我已经找到了所有Jackson需要依赖。所以我更喜欢配置Jersey禁用MOXy如下：

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;
    }
}

注意：

• 该方法getProperties()附带javax.ws.rs 2.0;
• no specific shared library is necessary for Jackson, but just for jstl and jax-rs 2.0;
• 里面没有任何信息web.xml是必须的;
• 据@abbas报道，JAX-RS 2.0默认带有Weblogic 12.2.1.3.0，在我的例子中，我有一个传递依赖javax.ws.rs:jsr311-api所以方法getProperties()没有被调用。

最终的 weblogic.xml

<?xml version="1.0" encoding="UTF-8"?>
<weblogic-web-app xmlns="http://xmlns.oracle.com/weblogic/weblogic-web-app">

    <context-root>/web-app</context-root>
    <container-descriptor>
        <prefer-application-packages>
            <package-name>org.apache.commons.net.*</package-name>
        </prefer-application-packages>
    </container-descriptor>

    <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>
</weblogic-web-app>

在 pom.xml 中提及 JAX-RS 2.0 作为依赖项

<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，您不需要将其部署为共享库。
