Thanks, it's a bug and be resolved in 2.7.1

@mercyblitz 您好，我的项目中，需要对接别人的feign接口sdk，同时我自己项目提供dubbo接口，但是在引入别人的feign sdk时，启动却报了类似的错误，

ConfigServletWebServerApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type 'org.springframework.core.env.Environment' available: expected single matching bean but found 2: dubboScanBasePackagesPropertyResolver,environment

版本：
org.apache.dubbo:dubbo-spring-boot-starter:2.7.0
org.springframework.cloud:spring-cloud-starter-openfeign:jar:2.0.2.RELEASE

请问是同一个bug吗，还是说我的配置问题

If your Spring Boot/Cloud 2 applications met with this issue , like below:

***************************
APPLICATION FAILED TO START
***************************

Description:

Field env in org.springframework.cloud.netflix.archaius.ArchaiusAutoConfiguration$PropagateEventsConfiguration required a single bean, but 2 were found:
	- dubboScanBasePackagesPropertyResolver: defined by method 'dubboScanBasePackagesPropertyResolver' in class path resource [org/apache/dubbo/spring/boot/autoconfigure/DubboRelaxedBinding2AutoConfiguration.class]
	- environment: a programmatically registered singleton

Action:

Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed

Please add these code for your application to resolve this issue:

Add "spring.main.allow-bean-definition-overriding" into application.properties

spring.main.allow-bean-definition-overriding = true

Re-define the bean named dubboScanBasePackagesPropertyResolver:

    // Bugfix code  to resolve Environment Beans conflict 
    @Primary
    @Bean(name = BASE_PACKAGES_PROPERTY_RESOLVER_BEAN_NAME)
    public PropertyResolver dubboScanBasePackagesPropertyResolver(ConfigurableEnvironment environment) {
        ConfigurableEnvironment propertyResolver = new AbstractEnvironment() {
            protected void customizePropertySources(MutablePropertySources propertySources) {
                Map<String, Object> dubboScanProperties = PropertySourcesUtils.getSubProperties(environment, DUBBO_SCAN_PREFIX);
                propertySources.addLast(new MapPropertySource("dubboScanProperties", dubboScanProperties));
            }
        };
        ConfigurationPropertySources.attach(propertyResolver);
        return new DelegatingPropertyResolver(propertyResolver);
    }


    private static class DelegatingPropertyResolver implements PropertyResolver {

        private final PropertyResolver delegate;

        DelegatingPropertyResolver(PropertyResolver delegate) {
            Assert.notNull(delegate, "The delegate of PropertyResolver must not be null");
            this.delegate = delegate;
        }

        @Override
        public boolean containsProperty(String key) {
            return delegate.containsProperty(key);
        }

        @Override
        @Nullable
        public String getProperty(String key) {
            return delegate.getProperty(key);
        }

        @Override
        public String getProperty(String key, String defaultValue) {
            return delegate.getProperty(key, defaultValue);
        }

        @Override
        @Nullable
        public <T> T getProperty(String key, Class<T> targetType) {
            return delegate.getProperty(key, targetType);
        }

        @Override
        public <T> T getProperty(String key, Class<T> targetType, T defaultValue) {
            return delegate.getProperty(key, targetType, defaultValue);
        }

        @Override

            return delegate.getRequiredProperty(key);
        }

            return delegate.getRequiredProperty(key, targetType);
        }

        @Override
        public String resolvePlaceholders(String text) {
            return delegate.resolvePlaceholders(text);
        }

        @Override
        public String resolveRequiredPlaceholders(String text) throws IllegalArgumentException {
            return delegate.resolveRequiredPlaceholders(text);
        }
    }

sohu234 · 2019-03-01T08:09:07Z

to resolve this problem ,i add @primary annotation on dubboScanBasePackagesPropertyResolver() method, eg:
@bean(name = BASE_PACKAGES_PROPERTY_RESOLVER_BEAN_NAME)
@primary
public PropertyResolver dubboScanBasePackagesPropertyResolver(ConfigurableEnvironment environment) {
ConfigurableEnvironment propertyResolver = new AbstractEnvironment() {
protected void customizePropertySources(MutablePropertySources propertySources) {
Map<String, Object> dubboScanProperties = PropertySourcesUtils.getSubProperties(environment, DUBBO_SCAN_PREFIX);
propertySources.addLast(new MapPropertySource("dubboScanProperties", dubboScanProperties));
}
};
ConfigurationPropertySources.attach(propertyResolver);
return propertyResolver;
}

@sohu234 Thanks for your code, I have updated my bugfix code.

thewkgithub · 2019-03-22T05:43:01Z

各位好.我使用上述的两种方式.还是有如何的错误提示,现在不知如何是好?

dubbo版本2.7.0
springboot版本2.1.3
springcloud版本Greenwich.SR1

According to the above method, I can't solve my problem.
