org.springframework.security.access.SecurityConfig：通过构造函数表示的不满意的依赖关系

Question

'org.springframework.security.access.SecurityConfig'：通过构造函数参数0表示的不满意依赖性：没有类型为[java.lang.String]的合格Bean

如何解决此错误？

春季4.1.3

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();
}
}

Answer 1

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

因此，请尝试更改行：

@Import({SecurityConfig.class})

至：

@Import({SecurityConfiguration.class})

Answer 2

我也有同样的例外，事实证明我的AbstractAnnotationConfigDispatcherServletInitializer#getRootConfigClasses返回一个包含org.springframework.security.access.SecurityConfig实例的数组，而不是我自己的WebSecurityConfigurerAdapter实现，该实现也恰好称为SecurityConfig 。 org.springframework.security.access.SecurityConfig构造函数采用单个字符串参数，这是来自不满足的依赖项自动装配错误的出处。

如果您使用的是名为SecurityConfig的类，则使您的导入是从正确的程序包中提取的，因为IDE的“自动导入”功能可能会给您带来麻烦，因为
