已解決：Spring Security：找不到WebSecurityConfigurerAdapter.class

我遇到了Spring Security的一個問題。我正在嘗試將其配置爲進行簡單登錄，但出現錯誤。下面是配置代碼：已解決：Spring Security：找不到WebSecurityConfigurerAdapter.class

package com.drg.AppConfig; 

import org.springframework.context.annotation.ComponentScan; 
import org.springframework.context.annotation.Configuration; 
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder; 
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; 

/** 
* Created by me on 09-Aug-17. 
*/ 

@Configuration 
@EnableWebSecurity 
public class SecurityConfiguration extends WebSecurityConfigurerAdapter { 
    @Override 
    protected void configure(AuthenticationManagerBuilder auth) throws Exception { 
     auth.inMemoryAuthentication() 
       .withUser("user").password("password").roles("USER").and() 
       .withUser("admin").password("password").roles("USER","ADMIN"); 
    } 

    @Override 
    protected void configure(HttpSecurity http) throws Exception { 
     http.authorizeRequests() 
       .antMatchers("/auth").permitAll() 
       .antMatchers("/").permitAll() 
       .antMatchers("/program/").access("hasRole(ROLE_USER')") 
       .antMatchers("/admin").access("hasRole(ROLE_ADMIN')") 
       .anyRequest().permitAll(); 
    } 

}

這裏是錯誤：Spring Security的我已經添加了以下相關

可能有人請幫助我在這裏找到解決方案？我如何避免我遇到的異常。請注意，該類是從Maven依賴項下載的。

能幫你在你的M2存儲庫驗證，如果你有罐子彈簧安全-config-4.2.3-RELEASE.jar？另外我有一個類似的配置，但我不使用配置和EnableWebSecurity在您的IDE類 – cralfaro

看到maven依賴項，並檢查是否彈簧安全jar被添加，並有類裏面 –

你說這個類已被下載，由於依賴但你確定嗎？類似於其他人所說的，你是否已經在項目目錄中執行了'mvn clean install'並且已經看到從Maven倉庫下載了依賴項？ –

解決方案：似乎春天的安全庫沒有添加到項目構建配置中的工件。此外，我已經改變了SecurityConfiguration類體：

@Autowired 
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception { 
     auth 
       .inMemoryAuthentication() 
       .withUser("user").password("password").roles("USER").and() 
       .withUser("admin").password("password").roles("USER","ADMIN"); 

    } 

    @Override 
    protected void configure(HttpSecurity http) throws Exception { 
     http.authorizeRequests() 
       .antMatchers("/").permitAll() 
       .antMatchers("/admin").access("hasRole('ADMIN')") 
       .and().formLogin(); 
     http.csrf().disable(); 
    }

我已經添加了初始化類巫婆延伸AbstractSecurityWebApplicationInitializer

package com.dragos.config; 

import org.springframework.security.web.context.AbstractSecurityWebApplicationInitializer; 





public class SecurityWebApplicationInitializer extends AbstractSecurityWebApplicationInitializer { 
}
