Description:

Field authenticationManager in cn.netkiller.oauth2.config.AuthorizationServerConfigurer required a bean of type 'org.springframework.security.authentication.AuthenticationManager' that could not be found.

The injection point has the following annotations:
	- @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

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

注入 @Bean @Override public AuthenticationManager authenticationManagerBean() 即可解決

		
package cn.netkiller.oauth2.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

@EnableGlobalMethodSecurity(prePostEnabled = true)
@Configuration
@EnableWebSecurity
public class WebSecurityConfigurer extends WebSecurityConfigurerAdapter {

	public WebSecurityConfigurer() {
		// TODO Auto-generated constructor stub
	}

	// 此處必須聲明這個bean類，否則無法注入AuthenticationManager
	@Bean
	@Override
	public AuthenticationManager authenticationManagerBean() throws Exception {
		return super.authenticationManagerBean();
	}

	protected void configure(HttpSecurity http) throws Exception {
		http.formLogin().and().authorizeRequests().anyRequest().authenticated().and().logout().permitAll().and().csrf().disable();
	}
