在 Spring.NET 验证中加载正确的上下文

Question

问题：当我尝试使用配置文件中的 Sprint.NET 验证来验证名为 StudyEnvironment 的业务对象时，我遇到了此异常。

'StudyEnvironment' node cannot be resolved for the specified context [Validation.Models.StudyEnvironment].

以下是重现异常的步骤，它在最后一行引发。

问题：我在这里遗漏了什么吗？我是否需要在配置文件中以某种 xml 格式声明我的业务对象？或者 Spring.NET 只是神奇地选择了它，我是 Spring.NET 的新手。

步骤 1：定义一个类

namespace Validation.Models
{
    public class StudyEnvironment
    {
        private Guid id;
        public String Name { get; set; }


        public StudyEnvironment()
        {
            this.id = Guid.NewGuid();
        }   
    }
}

在 web.config 中添加验证部分

<configuration>
  <configSections>
    <sectionGroup name="spring">      
      <section name="parsers" type="Spring.Context.Support.NamespaceParsersSectionHandler, Spring.Core"/>
      <section name="context" type="Spring.Context.Support.ContextHandler, Spring.Core" />
      <section name="objects" type="Spring.Context.Support.DefaultSectionHandler, Spring.Core" />
    </sectionGroup>
  </configSections>
  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
    <spring>
      <context>
        <resource uri="config://spring/objects" />
      </context>            
      <objects xmlns="http://www.springframework.net" xmlns:v="http://www.springframework.net/validation">        
        <v:group id="envValidator">
          <v:required id="environmentValidator" test="StudyEnvironment.Name">
            <v:message id="error.environmentName.required" providers="errors"/>
          </v:required>
        </v:group>
      </objects>
      <parsers>
        <parser type="Spring.Validation.Config.ValidationNamespaceParser, Spring.Core" />
      </parsers>    
    </spring>
</configuration>

步骤 3：验证调用

StudyEnvironment env = new StudyEnvironment();
env.Name = "test";

IValidator validator = ContextRegistry.GetContext().GetObject("envValidator") as IValidator;
IValidationErrors validationErrors = new ValidationErrors();
bool isValid = validator.Validate(env, validationErrors);

Answer 1

试试这个：

<v:group id="envValidator">
   <v:required id="environmentValidator" test="Name">
      <v:message id="error.environmentName.required" providers="errors"/>
   </v:required>
</v:group>
