WebLogic 12.1.3中的JSON-B作为JDK 8的新功能

标签： java weblogic

我试图在运行于WebLogic 12c（12.1.3）中的简单RESTful中实现JSON-B，该项目的部署没有错误，但是在调用JsonbBuilder.create（）

时

Resource.java 

@POST
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.TEXT_PLAIN)
public String getText(String arg) {
    Jsonb jsonb = JsonbBuilder.create();
    RespSmsNexmo respFromJson = jsonb.fromJson(arg, RespSmsNexmo.class);

    return respFromJson.text;
}

它产生了这个：

在pom.xml文件中，我没有声明任何依赖项，因为JDK 8足以使用JSON-B

pom.xml 

<dependencies>
    <dependency>
        <groupId>javax</groupId>
        <artifactId>javaee-api</artifactId>
        <version>8.0</version>
        <type>jar</type>
    </dependency>

    <dependency>
        <groupId>javax</groupId>
        <artifactId>javaee-web-api</artifactId>
        <version>8.0</version>
        <scope>provided</scope>
    </dependency>
</dependencies>

我会很乐意解决这个问题。

WebLogic正在Java 8上运行，如下所示：

答案 0 :(得分：2)

我做了一个简单的测试隔离，我的意思是，没有在WebLogic中部署应用程序，而是在终端中运行，并且我得到了非常相似的错误：

Exception in thread "main" javax.json.bind.JsonbException: JSON Binding provider org.eclipse.yasson.JsonBindingProvider not found
    at javax.json.bind.spi.JsonbProvider.provider(JsonbProvider.java:120)

经过研究，我发现here对于添加一些依赖关系是必需的：

<dependency>
    <groupId>javax.json.bind</groupId>
    <artifactId>javax.json.bind-api</artifactId>
    <version>1.0</version>
</dependency>

<dependency>
    <groupId>org.eclipse</groupId>
    <artifactId>yasson</artifactId>
    <version>1.0</version>
</dependency>

<dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>javax.json</artifactId>
    <version>1.1</version>
</dependency>

测试可以按预期进行。 现在的主题是，我无法在添加此依赖项的WebLogic中部署项目。因此，我将在另一个线程中对此进行询问。
