所以我想通过DropWizard资源更改用于验证模型的验证消息.

我正在使用java bean验证注释.例如,这是我要验证的字段之一:

@NotEmpty(message = "Password must not be empty.")

我可以使用验证器按预期测试它的工作原理.

但是,当我使用DropWizard对资源进行验证时,它会为该消息添加一些额外的内容.我看到的是这个 - password Password must not be empty. (was null)我发现这里的代码 - https://github.com/dropwizard/dropwizard/blob/master/dropwizard-validation/src/main/java/io/dropwizard/validation/ ConstraintViolations.java

具体这个方法 -

public static <T> String format(ConstraintViolation<T> v) {
    if (v.getConstraintDescriptor().getAnnotation() instanceof ValidationMethod) {
        final ImmutableList<Path.Node> nodes = ImmutableList.copyOf(v.getPropertyPath());
        final ImmutableList<Path.Node> usefulNodes = nodes.subList(0, nodes.size() - 1);
        final String msg = v.getMessage().startsWith(".") ? "%s%s" : "%s %s";
        return String.format(msg,
                             Joiner.on('.').join(usefulNodes),
                             v.getMessage()).trim();
    } else {
        return String.format("%s %s (was %s)",
                             v.getPropertyPath(),
                             v.getMessage(),
                             v.getInvalidValue());
    }
}

有什么办法可以覆盖这种行为吗？我只想显示我在注释中设置的消息...

我正在尝试从C#运行一个powershell脚本.我没有问题将字符串传递给脚本但是当我尝试将数组传递给powershell脚本时,会抛出异常.这是C#代码:

string [] test = {"1","2","3","4"};

RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();
Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration);

runspace.ApartmentState = System.Threading.ApartmentState.STA;
runspace.ThreadOptions = PSThreadOptions.UseCurrentThread;

runspace.Open();
RunspaceInvoke invoker = new RunspaceInvoke();
invoker.Invoke("Set-ExecutionPolicy Unrestricted");

Pipeline pipeline = runspace.CreatePipeline();
Command myCmd = new Command(@"C:\test.ps1");
CommandParameter param = new CommandParameter("responseCollection", test);
myCmd.Parameters.Add(param);
pipeline.Commands.Add(myCmd);

// Execute PowerShell script
Collection<PSObject> results = pipeline.Invoke();

这是powershell脚本:

param([string[]] $reponseCollection)
$a = $responseCollection[0]

每次执行此代码时抛出:

Cannot index into a null array.

我知道在将字符串传递给powershell脚本时执行powershell脚本的代码是正确的,它已经过全面测试.

我有以下代码,我测试和工作:

    using (new Impersonator("Administrator", "dev.dev", #########"))
    {
        RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();
        Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration);

        runspace.Open();

        RunspaceInvoke scriptInvoker = new RunspaceInvoke(runspace);
        scriptInvoker.Invoke("Set-ExecutionPolicy Unrestricted");

        Pipeline pipeline = runspace.CreatePipeline();
        Command myCmd = new Command(@"C:\test.ps1");
        myCmd.Parameters.Add(new CommandParameter("upn", upn));
        myCmd.Parameters.Add(new CommandParameter("sipAddress", sipAddress));
        pipeline.Commands.Add(myCmd);

        // Execute PowerShell script
        Collection<PSObject> results = pipeline.Invoke();
    }

但是,当我尝试将该函数包含在另一个项目中,以便从Web服务调用它时,它会抛出一个execption:

    System.Management.Automation.CmdletInvocationException: Access to the registry key 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell' is denied. ---> System.UnauthorizedAccessException: Access to the registry key 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell' is denied.

我不知道为什么会这样.任何帮助,将不胜感激.
