Jenkins HelloWorld插件在重新启动后不会保持配置

我一直在尝试创建我的第一个jenkins插件。一切都很好，只是在jenkins服务重新启动后，全局配置不会持久化

只要服务没有重新启动，配置就可以正常保存

全局配置文件

<j:jelly xmlns:j="jelly:core" xmlns:st="jelly:stapler" xmlns:d="jelly:define" xmlns:l="/lib/layout" xmlns:t="/lib/hudson" xmlns:f="/lib/form">

心满意足 假的

描述符本身如下所示

// Overridden for better type safety.
// If your plugin doesn't really define any property on Descriptor,
// you don't have to do this.
@Override
public DescriptorImpl getDescriptor() {
    return (DescriptorImpl)super.getDescriptor();
}

/**
 * Descriptor for {@link HelloWorldBuilder}. Used as a singleton.
 * The class is marked as public so that it can be accessed from views.
 *
 * <p>
 * See <tt>src/main/resources/hudson/plugins/hello_world/HelloWorldBuilder/*.jelly</tt>
 * for the actual HTML fragment for the configuration screen.

@Extension // This indicates to Jenkins that this is an implementation of an extension point.
public static final class DescriptorImpl extends BuildStepDescriptor<Builder> {
    /**
     * To persist global configuration information,

    public FormValidation doCheckName(@QueryParameter String value)
            throws IOException, ServletException {

            return FormValidation.warning("Isn't the name too short?");
        return FormValidation.ok();
    }

    public boolean isApplicable(Class<? extends AbstractProject> aClass) {

    }

    /**

@Extension//这向Jenkins表明这是一个扩展点的实现。
公共静态最终类描述符RIMPL扩展了BuildStepDescriptor{
/**

*只需将其存储在字段中并调用save（）。
*
*
*如果不希望字段被持久化，请使用transient。
*/
私用法语；
/**
*对表单字段“name”执行动态验证。
*
*@param值
*此参数接收用户键入的值。
*@返回
*指示验证结果。此结果将发送到浏览器。
*/
public FormValidation doCheckName（@QueryParameter字符串值）
抛出IOException、ServletException{
如果（value.length（）==0）
return FormValidation.error（“请设置名称”）；
if（value.length（）<4）
returnformvalidation.warning（“名称不是太短了吗？”）；
返回FormValidation.ok（）；
}
公共布尔值是可应用的（类），因此这是hello world应用程序的问题。您需要在构造函数中定义要加载配置的值

public DescriptorImpl(){
        load();
    }

这解决了我看到的配置未持久化的问题。
