Spring Boot Togglz -没有类型为UserProvider错误的合格bean

Question

我正在尝试将togglz添加到我的sprint启动应用程序中，但是在启动时我得到了以下错误：

2016-12-21 12:41:34.482 ERROR 43583 --- [ost-startStop-1] o.s.b.c.embedded.tomcat.TomcatStarter    : Error starting Tomcat context: org.springframework.beans.factory.UnsatisfiedDependencyException

似乎在配置上有问题，但是我似乎已经按照https://www.togglz.org/documentation/spring-boot-starter.html上的建议把一切都准备好了

我的设置如下：

package com.togglz;

import java.io.File;

import org.springframework.stereotype.Component;
import org.togglz.core.Feature;
import org.togglz.core.manager.TogglzConfig;
import org.togglz.core.repository.StateRepository;
import org.togglz.core.repository.file.FileBasedStateRepository;
import org.togglz.core.user.FeatureUser;
import org.togglz.core.user.SimpleFeatureUser;
import org.togglz.core.user.UserProvider;

@Component
public class TogglzConfiguration implements TogglzConfig {

    public Class<? extends Feature> getFeatureClass() {
        return Features.class;
    }

    public StateRepository getStateRepository() {
        return new FileBasedStateRepository(new File("application-local.properties"));
    }

    public UserProvider getUserProvider() {
        return new UserProvider() {
            @Override
            public FeatureUser getCurrentUser() {
                return new SimpleFeatureUser("admin", true);
            }
        };

    }
}

和

package com.togglz;

import org.springframework.stereotype.Component;
import org.togglz.core.Feature;
import org.togglz.core.annotation.Label;
import org.togglz.core.context.FeatureContext;


    @Component
    public enum Features implements Feature {

        @Label("Feature1")
        FEATURE_ONE,

        @Label("Feature2")
        FEATURE_TWO;

        public boolean isActive() {
            return FeatureContext.getFeatureManager().isActive(this);
        }
    }

我的应用程序属性文件包含以下内容：

togglz:
  enabled: true
  feature-enums: com.togglz.Features
    FEATURE_ONE: true
    FEATURE_TWO: false

其他人有没有经历过这个问题，或者知道如何解决它？我希望我的getUserProvider()能处理一些事情，但可能不是..

Answer 1

你在你的函数中缺少 @Bean注解，这是一个问题。

Spring正在尝试搜索togglz配置其用户提供程序所需的userprovider bean

Answer 2

看起来Spring Boot版本的升级成功了……
