Question

error Balana error 我正在研究月食，我已经在月食中添加了Maven，现在我想与Balana一起测试一些我编写的策略。

我已经编辑了pom文件并添加了此依赖项：

<dependencies>
    <dependency>
        <groupId>org.wso2.balana</groupId>
        <artifactId>org.wso2.balana</artifactId>
        <version>1.1.12</version>
    </dependency>
</dependencies>

当我尝试通过Balana开始学习时，请编写以下代码：

私人静态Balana巴拉那；

private static void initBalana（）{

try{
        // using file based policy repository. so set the policy location as system property
        String policyLocation = (new File(".")).getCanonicalPath() + File.separator + "resources";
        System.setProperty(FileBasedPolicyFinderModule.POLICY_DIR_PROPERTY, policyLocation);
    } catch (IOException e) {
        System.err.println("Can not locate policy repository");
    }
    // create default instance of Balana
    balana = Balana.getInstance();
}

它在大多数代码中给了很多错误！

编辑：首先，它给出了图片... 我曾尝试解决它，但是出现了其他错误。因此：

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory

    at java.lang.ClassLoader.loadClass(Unknown Source)
    ... 3 more

任何帮助...谢谢...

Answer 1

由于您在类路径中缺少logfactory类，因此引发了以上异常添加此依赖项

<dependency>
    <groupId>commons-logging</groupId>
    <artifactId>commons-logging</artifactId>
    <version>1.1.1</version>
</dependency>
