Consider defining a bean of type 'org.springframework.security.authentication.AuthenticationManager' in your configuration.

在你的配置中考虑定义一个类型为 'org.springframework.security.authentication.AuthenticationManager' 的bean。

你可以创建一个配置类，在该类中创建一个对应的bean。在Spring Boot 1.4及以后的版本中，你需要手动创建一个RestTemplate的配置。以下是一个示例代码：

package com.xxx.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;

@Configuration
public class Config {
    @Bean
    public AuthenticationManager authenticationManager() {
        // 实现认证管理器的逻辑
    }
}

在上述示例中，我们创建了一个名为authenticationManager的bean，其类型为'org.springframework.security.authentication.AuthenticationManager'。你可以根据你的具体需求来实现该bean中的认证管理器逻辑。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
