小编lik*_*amp的帖子

我在网上查看了几乎所有与此问题相关的答案,但无法在我的代码中找出问题所在.

这是我的JSP页面.

<form:form method="POST" commandName="category" modelAttribute="category" action="search_category">
    <form:input path="category_name" /> 
    <input type="submit" value="Submit">  
</form:form>

当我删除

<form:input path="category_name" /> 

它工作正常.我可以与我的控制器通信.所以问题与这条线有关.

@Controller
public class SearchCategory {

    @Autowired      
    private CategoryService categoryService;

    @RequestMapping(value = "/search_category",  method = RequestMethod.POST)
    public @ResponseBody String searchCategoryFromDatabase(@ModelAttribute("category") Category category, BindingResult result){        

        return "something";
    }
}

这是我的web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

当我想从不同的服务器访问远程 Wildfly 服务器上的 EJB 时，出现以下错误。

Error: Authentication failed: all available authentication mechanisms failed:
   JBOSS-LOCAL-USER: javax.security.sasl.SaslException: Failed to read server challenge [Caused by java.io.FileNotFoundException: /../wildfly/standalone-/tmp/auth/X.challenge (No such file or directory)]
   DIGEST-MD5: Server rejected authentication

如果我在服务器内访问 EJB，我不会收到任何身份验证错误。我使用以下方式访问服务器；

http-remoting://server1:8080

基本上如果我在server1中调用这个，就没有问题。如果我从 server2 调用它，我会收到错误。我假设它在 server2 中查找 server1 中存在的 auth 文件。

我不确定是否必须在 EJB 或 Wildfly 上进行一些配置才能启用来自不同服务器的访问。我确实完成了网上提供的所有步骤，但显然我遗漏了一些东西。

从 Xcode 构建我的 React Native 项目会出现以下错误；

Multiple commands produce '/Users/USERNAME/Library/Developer/Xcode/DerivedData/PROJECT-grjkuplqgvolxebnwadcuuhwkdak/Build/Intermediates.noindex/ArchiveIntermediates/PROJECT/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/AccessibilityResources.bundle':
1) Target 'React-Core.common-AccessibilityResources' has create directory command with output '/Users/USERNAME/Library/Developer/Xcode/DerivedData/PROJECT-grjkuplqgvolxebnwadcuuhwkdak/Build/Intermediates.noindex/ArchiveIntermediates/PROJECT/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/AccessibilityResources.bundle'
2) Target 'React-Core.common-CoreModulesHeaders-AccessibilityResources' has create directory command with output '/Users/USERNAME/Library/Developer/Xcode/DerivedData/PROJECT-grjkuplqgvolxebnwadcuuhwkdak/Build/Intermediates.noindex/ArchiveIntermediates/PROJECT/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/AccessibilityResources.bundle'

我检查了“多个命令产生”错误的其他答案，但到目前为止还没有运气。不过，它们主要与矢量图标有关。

如何修复 AccessibilityResources 的此错误？
