java.lang.NoClassDefFoundError：net/sf/json/JSONArray

Question

我正在尝试在我的项目中使用 json-lib (net.sj.json)。

我查看了该库所需的一些依赖项，并按字面意思添加了所有依赖项，但仍然得到 NoClassDefFoundError。

java.lang.NoClassDefFoundError: net/sf/json/JSONArray

这是我的依赖项，

谁能帮我解决这个问题？

Answer 1

尝试改变：

    <dependency>
        <groupId>net.sf.json-lib</groupId>
        <artifactId>json-lib</artifactId>
        <version>2.2.3</version>
        <classifier>jdk15</classifier>
    </dependency>

到：

    <dependency>
            <groupId>net.sf.json-lib</groupId>
            <artifactId>json-lib-ext-spring</artifactId>
            <version>1.0.2</version>
    </dependency>

Answer 2

为该引用类找到NoClassDefFoundError，无论它在编译时是否可用。

要解决此错误，请添加 this 最新的 json 依赖项。

<dependency>
    <groupId>net.sf.json-lib</groupId>
    <artifactId>json-lib</artifactId>
    <version>2.4</version>
</dependency>

Answer 3

<dependency>
    <groupId>net.sf.ezmorph</groupId>
    <artifactId>ezmorph</artifactId>
    <version>1.0.6</version>
</dependency>
<dependency>
    <groupId>net.sf.json-lib</groupId>
    <artifactId>json-lib</artifactId>
    <version>2.4</version>
</dependency>
