小编kri*_*aex的帖子

我不明白Spock测试中Mock,Stub和Spy之间的区别,我在网上看过的教程并没有详细解释它们.

我有一个使用Comparable <>定义'自然排序顺序'的对象.这些存储在TreeSet中.

除了删除和重新添加对象之外,还有另一种方法可以在更新用于定义排序顺序的成员时更新排序吗？

在调试时,Eclipse中的Debug视图显示调用堆栈.哪个好.但是我希望能够过滤掉我绝对不关心的所有调用,例如Spring和JUnit runner.

这是我现在调用堆栈的一个例子.我想把这些条目保持为粗体,同时隐藏所有其他条目.有可能以任何方式吗？(插件,下一个Eclipse发行版,配置......)

我在新标签页中打开了image/x-png类型的图片,但Chrome刚下载了它.我用Google搜索并发现Chrome不会将image/x-png解释为图像文件.

所以,我想编辑Chrome的MIME类型映射.可能吗？

当我使用imaps连接到我的imap服务器时,它很脆弱.

你能告诉我如何忽略javamail中的服务器证书错误

将 Java 版本更改为 17 后，我无法构建 Gradle 项目。

我正在使用 Gradle 7.3.1 版本，并且 Gradle 属性中有以下行：

org.gradle.jvmargs=-Dfile.encoding=UTF-8 -Xms1g -Xmx4g -XX:+UseG1GC -XX:+CMSClassUnloadingEnabled

然后我得到以下错误

Unrecognized VM option 'CMSClassUnloadingEnabled'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

如果我删除-XX:+CMSClassUnloadingEnabled然后我收到此错误：

Unable to make field private int java.lang.reflect.Field.modifiers accessible: module java.base does not "opens java.lang.reflect" to unnamed module @1b9ee3e0

之后mvn clean install我看到下列情况除外: …

我已经看到已经提出了一些这个问题的实例.但是,我相信我满足这些解决方案中列出的标准.即我很确定我的课程路径上有所需的罐子+我的原理配置地址按顺序查看.

一个解决方案提到该问题可能是由于在类路径上有另一个XML解析器引起的.我在我的类路径上有dom4j,但我已将其删除以进行测试,问题仍然存在.

这是我的类路径:

在我的请求中,我有一个参数名称"accessToken",如何从ProceedingJoinPoint获取请求参数值？

public Object handleAccessToken(ProceedingJoinPoint joinPoint) throws Throwable { 
    final Signature signature = joinPoint.getStaticPart().getSignature();
    if (signature instanceof MethodSignature) {
        final MethodSignature ms = (MethodSignature) signature;
        String[] params = ms.getParameterNames();
        for (String param : params) {
            System.out.println(param);
            // here how do i get parameter value using param ?
        }
    }
}

通话方式:

public MyResponse saveUser(
    @RequestParam("accessToken") String accessToken,
    @RequestBody final UserDto userDto
) {
    // code 
}

我想在AOP中获取此访问令牌.

提前致谢.

我有一个项目的.classpath文件,其中包含所有类路径条目.现在它有以下入口 -

<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/J2SE-1.5">
</classpathentry>

现在,从这个条目开始,我想以编程方式通过java代码找到所有与这个库相关的jar文件？有没有办法阅读所有的罐子？
