在Spring Boot中创建自定义安全配置时出错

Question

ConfigServletWebServerApplicationContext：上下文初始化过程中遇到异常-取消刷新尝试：org.springframework.beans.factory.unsatisfieddependencyException：创建名为“security config”的bean时出错：通过字段“reader repository”表示的不满足依赖项；嵌套异常为org.springframework.beans.factory.BeanCreationException：创建名为“Reader Repository”的bean时出错：调用init方法失败；嵌套异常为java.lang.IllegalArgumentException：不是托管类型：class java.io.Reader

package com.example.readinglist;

import java.io.Reader;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.stereotype.Repository;

@Repository
public interface ReaderRepository extends JpaRepository<Reader, String> {

    UserDetails findOne(String username);

}

ReadingListApplication：

package com.example.readinglist;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class ReadinglistApplication {

    public static void main(String[] args) {
        SpringApplication.run(ReadinglistApplication.class, args);
    }

}

package com.example.readinglist;

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter{

    @Autowired
    private ReaderRepository readerRepository;


    @Override
    protected void configure(HttpSecurity http) throws Exception{

        http.authorizeRequests()
        .antMatchers("/")
        .access("hasRole('Reader')")
        .antMatchers("/**").permitAll().and().formLogin().loginPage("/login")
        .failureUrl("/login?error=true");
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {

        auth.userDetailsService(new UserDetailsService(){

            @Override
            public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
                return readerRepository.findOne(username);
            }
        });
    }
}

您导入了错误的读取器实体-->您导入了“import java.io.Reader；”您需要导入您的自定义阅读器实体类。
