java - 如何在Spring Boot中更改ProviderSignInController中的属性signUpUrl

Question

简而言之

我需要更改 Spring Boot 自动配置中定义的 bean 的属性值，该属性无法从 application.properties 进行配置

描述性

我想更改 bean ProviderSignInController 的 signUpUrl。根据文档，这是无法在属性文件中更改的。

http://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html

所以我做了这样的事情。

@Configuration
public class SomeConfig {

    @Autowired
    public void configureProviderSignInController(ProviderSignInController signInController){
        signInController.setSignUpUrl("/register");
    }

最终出现以下错误

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.springframework.social.connect.web.ProviderSignInController] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}
    at org.springframework.beans.factory.support.DefaultListableBeanFactory.raiseNoSuchBeanDefinitionException(DefaultListableBeanFactory.java:1301)
    at org.springframework.beans.factory.support.DefaultListableBeanFactory.doResolveDependency(DefaultListableBeanFactory.java:1047)
    at org.springframework.beans.factory.support.DefaultListableBeanFactory.resolveDependency(DefaultListableBeanFactory.java:942)

但是根据自动配置，这个bean应该可用

https://github.com/spring-projects/spring-boot/blob/master/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/social/SocialWebAutoConfiguration.java

如果我做错了，请帮助和指导我。

该错误描述问题是您没有在 configureProviderSignInController 的方法签名中实例化类型为 ProviderSignInController 的 bean。相反，您需要使用 Controller 所需的正确构造函数签名在您的配置之一中实例化和配置 Controller :

@Configuration
@EnableSocial
public class SocialConfig implements SocialConfigurer {

    ...

    @Bean
    public ProviderSignInController providerSignInController(
                ConnectionFactoryLocator connectionFactoryLocator,
                UsersConnectionRepository usersConnectionRepository) {
        ProviderSignInController controller = new ProviderSignInController(
            connectionFactoryLocator, usersConnectionRepository,
            new SimpleSignInAdapter());
        controller.setSignUpUrl("/register");
        return controller;
    }

}

或者，如果您使用 XML 配置:

<bean class="org.springframework.social.connect.signin.web.ProviderSignInController">
    <!-- relies on by-type autowiring for the constructor-args -->
    <property name="signUpUrl" value="/register" />
</bean>
