java - org.springframework.security.access.SecurityConfig : Unsatisfied dependency expressed through constructor

Question

'org.springframework.security.access.SecurityConfig':通过构造函数参数 0 表示的不满足的依赖关系:没有 [java.lang.String] 类型的合格 bean

如何修复这个错误？

Spring 4.1.3

代码

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
    auth.inMemoryAuthentication().withUser("user").password("abc").roles("DBA", "ADMIN");
}

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.authorizeRequests()
            .antMatchers("/abc/**").hasRole("ADMIN")
            .anyRequest().authenticated();
}
}

错误

网络配置

@EnableWebMvc
@Configuration
@Import({SecurityConfig.class})
@ImportResource("classpath*:contexts/all-beans.xml")
@ComponentScan(basePackages = "com.abc.web")
public class WebConfiguration extends WebMvcConfigurerAdapter {
@Override
public void addCorsMappings(CorsRegistry registry) {
    registry.addMapping("/")
            .allowedOrigins("*");
}
}

您正在导入 @Import({SecurityConfig.class})但是在您的项目中，扩展了 WebSecurityConfigurerAdapter 的类是SecurityConfiguration .

所以尝试改变行:

@Import({SecurityConfig.class})

到:

@Import({SecurityConfiguration.class})
